How to fix a cracked one. How to repair a cracked bumper yourself. Video about sealing defects with fiberglass

Once upon a time, slate roofing was considered perhaps the most versatile: affordable, durable and unpretentious. Cheap and cheerful, as they say. But for all the strength of asbestos fibers, such sheets are not very resistant to mechanical stress: over time, many small cracks always appear on them, through which moisture easily seeps through.

Luckily, at least a slate roof doesn't corrode like a metal roof that rusts from the slightest scratch, but repairs will still need to be done from time to time. So how to close a crack in the slate and stop the further destruction of other sheets? Now we will understand everything in more detail.

Fragile slate is damaged quite easily:

1. from impact loads. From careless walking on the roof.
2. From microcracks due to falling tree branches.
3. From mosses, lichens and other misfortunes. Moss and lichens, which are especially fond of slate, not only deprive it of its aesthetics, but also slowly destroy it!
4. From time. Unfortunately, the service life of a slate roof is not long, and after 10-12 years the first cracks and holes appear.
5. From constantly stagnant rainwater. Any roof, and not only slate, has weak spots around skylights and pipes. Immediately pay attention to these elements - it is not difficult to seal them.
6. The angle of the roof is not suitable for slate roofing.
7. The laying of slate was carried out with certain violations, and the material constantly experiences excessive stress. It’s also bad if during installation you used ordinary nails without rubber gaskets to fasten the sheets - then you can’t do without cracks.
8. Careless transportation and storage. Such defects may not be detected immediately, but they will immediately become noticeable from walking on them on the roof.
9. Sharp temperature changes. Believe me, any asbestos-cement material does not like this.
10. Due to disproportionately small holes for screws or nails. Do not forget that metal is characterized by seasonal expansion, and therefore you need to leave a little more space for such fastening (but not so that it becomes numb rainwater). That's why rubber gaskets are needed.

And finally, snow can add new problems. The fact is that the slate roof does not have such smoothness as the metal one, and snow constantly lingers on it. And just a little sunlight is enough to flood all this snow cap from below - as a result, the melted water flows down to the eaves, where it meets with a new layer of snow (the eaves always colder than the roof above living quarters). Here, the melt water freezes again and, in the form of ice, is already destroying not only slate sheets, but also drainage system. In addition, all this mass, under natural expansion from low temperature, is clogged under the sheets and from there, melting, it falls directly onto the rafters or into the insulation.

Also, often the cause of cracks in slate lies in its incorrect manufacturing technology. And at several stages:

• During the preparation of the mortar, less cement was added than the factory recipe required (guess why).
• Gross violations of the production technology of slate sheets (handicraft production).
• Short asbestos fibers were used in the slate (and this is the manufacturer's decision).
• Poor quality processing of finished slate sheets (lack of control).
• Reduction of material opening period (a need 28 days).

And now let's talk about how and how to fix holes and cracks on the slate roof of the house.

How to detect coating defects?

Agree that it is quite difficult to notice new defects or cracks on an outwardly heterogeneous slate roof, while on a smooth seam roof or corrugated board it is easy to do even from a neighboring building. So pay attention to these warning signs that your roof needs urgent repair:

The fact is that unnoticed leaks are quite insidious: the rafters are immediately saturated with moisture, the thermal insulation becomes damp and deteriorates, and the ceiling needs repair. Go to the attic if you have such suspicions: if you smell dampness, then there is a problem. And individual mold spots indicate that there is a crack somewhere in the slate, but so far it does not make itself felt, except for small leaks. Check the under roof space of the slate roof also after every downpour.

We put a "diagnosis" on the cracks of the sheets

If the cracks went along the protruding waves of slate, then the bookmarks must be applied both from below and from above.

Cracks in the lower waves require the most complex solutions. After all, it is here that water will constantly stagnate, and it is rather difficult to achieve the necessary tightness.

But let's look first at the crack itself - a lot depends on this:

1. A crack that goes along the top wave of slate(it is the easiest to spot), usually does not leak due to the fact that the water under it does not stagnate. This is the most harmless crack, and it is easy to repair it - just bend the galvanized iron and slip it under the slate, and cover the crack itself with a special roofing tape.
2. A crack that goes along the bottom wave, the most dangerous - here you can not do without leaks. Use sealant, patch and folded sheet.
3. A crack that went across the slate sheet the most dangerous! And leaks alone are indispensable here - the crack will expand and move on to subsequent waves in the future.

Have you decided on your next renovation? Proceed with caution! Remember that in many countries of the world this roofing is completely prohibited due to harm to health, and therefore, when dismantling old sheets or machining, protect yourself from asbestos fibers. Here's how professional teams do it:

How to fix cracks and holes in slate?

Before applying any patch, it is important to completely clean the repaired surface of debris and moss, and then wash it with a powerful jet of water. And here is how to close up holes and holes in the slate on the roof with available materials and novelties of the construction market:

Method number 1. Cement and sand

Prepare a mixture of one part dry cement and two sifted sand. Fill with water and stir until desired consistency. close up. Let the cracks dry well and paint them in a suitable color.

Method number 2. Butyl rubber tape

A special butyl rubber tape is also good as a patch for holes and cracks. What is good, its surface is made of non-woven material, so that it is good to paint such a patch in the desired shade. And it's easy to work with:

• Step 1. Degrease the repaired area of ​​the slate sheet with gasoline.
• Step 2 Remove the protective strip from the tape and stick it to the damaged area.
• Step 3. Paint in color so that your roof does not look "patched".

Ready-made butyl patches are also used for repairs:

To seal cracks in slate, sickle is also used - a tape that gives strength to the putty joint of sheets. To do this, a layer of bitumen is first applied to the crack, then a sickle is applied to it, and then everything is again smeared with bitumen.

Or use the more expensive one modern version tapes that are designed specifically for the repair of such roofs:

Method number 3. hot bitumen

It is not difficult to prepare bituminous mastic on a fire:

1. We kindle a fire, put two bricks on the sides.
2. We take an old bucket, put a piece of bitumen in it.
3. We put the bucket on the fire and stir gently so that nothing catches fire.

If you work in sub-zero temperatures, add 10% waste to the bitumen to give it elasticity and avoid cracking the mastic. Especially if you process the edges of slate sheets:

Hot bitumen is also suitable for sealing small cracks:

But remember that any putty gives only a temporary effect. The problem with using traditional slate putties is that this roofing material little pliable for expansion, while putties usually have a completely different coefficient. That's why after a few cycles of temperature fluctuations, leakage problems return again. And sometimes it is much easier and more reliable to simply replace the defective sheet.

Method number 4. Putty from asbestos, cement and PVA

First, we take asbestos in finished form. If you didn’t manage to get one, just grate it from a piece of slate. Be sure to protect your respiratory tract during this work!

So, to prepare the mixture, you will need to mix 2 parts of cement, 3 asbestos and liquid solution from PVA glue and water, taken equally. Stir the mixture until it thickens like sour cream. If you cleaned part of the slate before repairing, wait until it dries completely. Next, apply the prepared mixture, treat with a solution of PVA and water (now the ratio is 1: 3) and apply 2 more layers of the mixture.

Method number 5. Finished putties

For the repair of such a roof, ready-made mixtures are well suited, which include waterproofing materials. You need to work with them like this:

• Step 1. We clean the repaired surface well.
• Step 2. Degrease the area with a solvent or acetone, dry well.
• Step 3. We prime the surface with a repair mixture, only diluted to a liquid state.
• Step 4. We apply the mixture with a special gun or spatula.
• Step 5. After 6 hours, cover with fiberglass and put a new layer of the mixture.

Please note that to carry out such repair work on a slate roof it is necessary in dry and cloudy weather so that the necessary components in the mixtures dry slowly.

Method number 6. Foam and epoxy

Close up cracks and holes in slate also liquid foam, but for this you will have to purchase a whole bottle. Practiced among home craftsmen and the so-called "three-layer" method:

• Step 1. We clean and degrease the area.
• Step 2. We close the crack with mounting foam.
• Step 3. Dry or just leave for a day.
• Step 4. Apply sealant.
• Step 5. Cover it all with resin.

Epoxy resin is also suitable for repairing a slate roof, which is much less destroyed under ultraviolet rays than polystyrene.

This is an expensive but reliable method to cope with small problems, although it is inconvenient to use it on an inclined plane. So, if the slate sheet is split along its entire length, fasten the wavy joints with epoxy glue. But first, fix them together from below with mounting tape, and only then fill the gap from above.

Method number 7. Tin patch

This method is suitable for repairing large holes and cracks in a slate roof. So, step by step:

• Step 1. Cut out a patch from tin, roll it into a tube.
• Step 2. We push it into the hole so that a hole can be made in the middle of the patch.
• Step 3. Insert a bolt with a gasket into the hole and press it.
• Step 4 Fill gaps with building sealant.

The repair of a slate roof must be approached seriously. If the patch will allow even a little water to pass further, the rafters will eventually become completely unusable.

Method number 8. Drying oil with chalk

This is one of the most proven folk methods. So, we clean the cracks, carefully cover them up, and after drying, paint with oil paint. That's all!

Method number 9. Moisture resistant glue

• Step 1. We wash the sheets well with ordinary water, three of them with a stiff brush.
• Step 2. We are waiting for the slate to dry and seal each hole with a piece of dense fabric so that its edges extend beyond the hole by about 3-4 cm. To do this, we impregnate the patch with moisture-resistant glue.
• Step 3. On top of the patch, once again apply a layer of glue (Emalit).
• Step 4 Turn over the damaged sheet and fill the hole with concrete.
• Step 5. Once the mortar has set, glue another patch.
• Step 6 At the end of the crack, we drill a hole and seal it with an elastic sealant.

Method number 10. Aluminium foil

Ordinary aluminum foil will also help to cope with cracks:

• Step 1. Remove the old fasteners from the sheet.
• Step 2. Round off the corners of the patch.
• Step 3. Fasten the foil and press it with a self-tapping screw.
• Step 4 If the slate on your roof is colored, repaint the patch in the same color.

In extreme cases, it is easier to replace any section of a slate roof than to repair it. Then cut out the necessary elements from the new sheets:

Often, the ridge of a slate roof also becomes unusable, which is not difficult to replace with metal or wood:

How to protect the slate from further destruction?

The situation is worse if the roof began to burst in different places. This is usually indicative of installation errors in due course, and the usual repair of the slate on the roof will only give a temporary effect. It is urgent to stop the destruction process:

• Method number 1. To prevent cracking, temporarily place a strip of cloth soaked in paint over the crack.
• Method number 2. Also, so that the crack does not go further, a hole is drilled in it and fixed with a self-tapping screw. Moreover, such a hole must be sealed with an additional roofing sealant, which will tighten, like rubber, the edges of the hole.

But, if in the next decade you are not going to change the entire roof, then approach the issue of repair more globally:

Or like this:

That's all! Choose the method for which you already have materials and you know how to work with them.

Being the most durable roofing material, slate has been used to cover buildings since the middle of the last century. But in spite of all his positive traits, time and mechanical influences can cause unexpected damage. And in this case, it is very important to know how to repair a crack in the slate, or to eliminate the resulting chip.

1 Crack in the slate - is it worth sounding the alarm?

To avoid having to completely replace the sheet, which is daunting task, you can use various methods fixing the defect. And, despite the requirement for certain skills, it is easier than replacing the entire sheet.

Most often, damage occurs due to the "aging" of the slate. But besides this, there are other reasons:

• the kit included a sheet created in violation of manufacturing technology;
• poor quality of processing the sheet itself at the final stage;
• low-quality asbestos material;
• error in choosing the angle of inclination when laying it;
• violation of the order of laying sheets, which caused additional stress;
• special nails were not used to fasten the slate;
• the crack appeared during the drilling of slate or its cutting;
• hard material on the roof as a result of gusts of wind or pranks of children.

Often roofing manufacturers do not comply with curing time requirements. It is determined by the standards in 28 days. But, as always, profit becomes a priority. Many reduce this period by sending unseasoned sheets for sale. This is the main reason for the increased fragility of slate. But the experience of roofing masters is the source of many recipes for repairing cracks and chips in slate.

Our advice and knowledge will help you choose the most suitable method. It is important to ensure that the problem is resolved as quickly as possible. Especially when the weather conditions do not allow for a long time to think.

2 Slate crack repair - ways to restore damaged sheets

One of the options when sealing cracks in slate requires a repair mixture, which is prepared independently. It consists of: asbestos, cement, water, PVA glue. The preparation of the mixture should be carried out in compliance with the ratio of asbestos and cement - 3 to 1, water and PVA glue are added in equal amounts to obtain the consistency of a homogeneous sour cream. It is very important to pay attention to the mixing process - the formation of lumps should not be allowed.

Before applying the solution, the crack must be prepared. If this is just a crack, then a sickle (fiberglass tape) is fixed on top of it, along the entire length. If there is significant damage or a hole, then it must be filled, for example, with raw rubber. On the damaged surface, you can now apply the resulting solution, trying to do it evenly. And it will be very good if the mixture significantly covers the damage zone.

Another method is based on the use of special aluminum foil. It is necessary to first apply the adhesive of the universal group to the foil, and then apply it to the damaged area. This provides a very strong connection between the foil and the roof, preventing water from entering. There is another way to cover up cracks in slate. For these purposes, silicone paste must be available. The pre-damaged area of ​​the slate must be cleaned, degreased and dried. The paste will stick well only on such an area.

The fourth option, demonstrating the possibility of how to close a crack in slate, is the proven method of using butyl rubber tape. The self-adhesive tape has high adhesive qualities. It is able to stick very firmly to almost any material - wood, plastic, iron, glass, film. When gluing a crack on asbestos slate, a high-quality overlay is obtained that does not allow water to enter, withstands any climatic influences, temperature changes. This tape is not afraid of dirt, dust or ultraviolet.

Based on the options described, you first need to decide what is best to cover up the cracks in the slate, or use tapes to get the most efficiency from the method used and lower costs for this repair.

3 How to close a crack in slate - basic rules

The first step in the slate repair process is always the preparation of the repair area. In no case should you start work if this stage has not been completed. Each material, and especially the repair mortar, is most effective at the very beginning after its preparation. Any delay leading to its untimely use could be a practical failure. The solution will lose its properties and will not provide high-quality protection.

The trash is removed first. The site of damage is thoroughly washed and degreased. Here you can use gasoline. When working with asbestos solution, it is necessary to use a respirator. The mixture does not need to be prepared in in large numbers. Its properties are lost with prolonged non-use. It is enough to knead in small volumes, covering the crack zone gradually. The solution itself is poured into the crack sequentially, twice. It is required to achieve a layer thickness of at least two millimeters.

If the damage is significant - the split occurred along the entire length of the sheet, you can use epoxy resin to glue parts of the sheet. Previously, an adhesive tape is used for connection from the inside. You can use a fixed galvanized patch - silicone or bituminous mastic is used in the junction area. This option is often used if the crack has passed over the entire surface of the sheet, starting from the site of the previous repair. To do this, the old fasteners are removed. After repairing the sheet, both parts of the slate are attached in new places.

Among the various repair methods, there is a method in which polyurethane foam is used. In the case of large holes, it is blown into the damaged area, observing the rules for using such material. And here it is necessary to fulfill one condition - when the foam has frozen, it must be cut along the contour of the sheet. On the outside of the slate along the damage, the foam itself must be protected by the sealant. According to it, additional processing is carried out with roofing mastic, which is intended for waterproofing roofs.

The repair of a crack that has damaged a slate sheet will be successful if high adhesion of materials is ensured - it is better to prime the damaged area with PVA glue.

And one more very important rule. In case of severe damage, for example, partial destruction of the sheet, the formation of significant and even several holes, the only solution is to completely replace such a slate sheet. Repair will not provide the slate with the required properties, will not be able to protect it from further damage and soaking. And this, in turn, will lead to leakage. In addition, the result will be meaningless financial and labor costs.

Despite the fact that the roofing of asbestos-cement sheets is durable after decades, external atmospheric and climatic factors have an impact on the material. Something has to be replaced, something to patch up, somewhere to block. This is where the application of knowledge in the field of construction is required, and if you know how to repair a crack in the slate on the roof, then such work will not seem difficult.

Cosmetic repairs will help extend the operational life of the roof for up to 10 years. Therefore, the topic is especially relevant. In the past, roofing was completed using oil paints and fabric strips. This technique was not famous for its special effect, and the state of the overlap improved for only a couple of years. Available today modern materials making the process of eliminating cracks and chips on the roof more efficient.

Simple house roof renovation

Roof leakage indicates damage to the integrity of the material. To get rid of this problem, you can use one of the effective ways. Any of them is easily applicable in practice and is not difficult, but here it is important to know how to close a crack in the slate on the roof. In 90% of cases, patching or sealing of the affected area of ​​the roof will be required.

Familiarize yourself with the options for action in the event of a roof leak, the easiest and fastest method to fix a leak, the slate patch technique. It is important to talk about such details in advance.

The most common technology for the restoration of asbestos-cement damaged sheets is the use of asbestos paste.

How to work with the material: application features

Using asbestos paste to seal cracks, take care of the preliminary dismantling of the damaged roof fragment and lower it to the ground.

What is required to prepare the composition

The mixture consists of two components: asbestos and cement. This pasta is easy to make at home.

Components:

• asbestos - 3 parts;
• cement - 1 part;
• water - 0.5 parts;
• dispersion polyvinyl acetate adhesive - 0.5 parts.

Water and glue can be added as needed until the paste reaches a creamy consistency.

For cooking:

• prepare a separate container;
• pour out required amount asbestos and cement (proportion 3:1);
• mix the ingredients thoroughly;
• add water and dispersion adhesive;
• Stir the paste until a smooth creamy consistency is achieved.

How to work with asbestos mixture

Knowing how to close a crack in the slate on the roof, you can get to work. Try to use cooked pasta immediately. During storage, the composition loses its properties. Therefore, prepare exactly as much grout as is needed to repair the roof of the house.

preparatory moment

Before sealing the roof, prepare the damaged area:

• clean the slate from debris;
• thoroughly rinse the place of the broken slate and degrease it. Gasoline is suitable for such purposes;
• if an ordinary crack has formed on the surface, stick a fiberglass tape (sickle) along the entire length, extending it by 5 cm in each direction from the crack (vertically);
• fill the voids of the crack with raw rubber or caulk them. The fibrous material can be further treated with a hydrophobic composition.

Application of asbestos cement paste

The composition is applied to the damaged area gradually, evenly distributing each of the layers over the surface. In this case, the total thickness of the applied paste must reach at least 2 mm. After the patch has dried, the seam must be treated with sandpaper.

When carrying out restoration, try to cover up so that the coverage area extends beyond the crack. Having repaired broken slate sheets, you can not worry that the roof will leak for the next 8-10 years.

Use of foil

Asbestos paste is not the only option for treating roof damage. If you do not know how to repair a crack in the slate on the roof, use foil instead of paste, on which a little universal glue is applied and applied to the damaged area from the wrong side. The tight fit of the patch is ensured by rounding the corners, so they bend less. The connection of the foil with the reconstructed surface is strong due to the universal adhesive composition used and reliably protects the interior of the attic from the penetration of water and moisture.

If you want to seal up that part of the roof where the fastener passes, then close the crack with foil and drill a hole for the fasteners in another part of the sheet.

After repair, the removed slate sheet is mounted in place. Do not forget about the use of special rubber gaskets for nails to protect the corrugated board from damage during installation. After completing the reconstruction, disguise the patch to match the tone of the roofing material. At this stage, work is carried out in dry weather, and when applying paint, a brush or roller is used. It is better to apply several layers, starting to re-paint only after the first has completely dried.

Some of the methods do not involve the dismantling of damaged products in the place where the slate burst. How to close the crack, if you need to go upstairs, read on. Such work is done directly on the roof, and for this it is vital to provide insurance.

Silicone paste for roof repair

Often, silicone paste is used to repair the roof. The tool is characterized by increased adhesion to materials made from asbestos cement.

Getting started, the damaged area is prepared: cleaned of dust and small dirt crumbs, using a brush for cleaning metal products. To do this, use acetone or a special solvent.

Before sealing the crack, it is filled with crushed asbestos chips, which are then filled with silicone glue for slate. Such a restoration is not difficult to carry out, and the whole process takes a maximum of a day and ends at the stage of tinting the treated area under the general style of the roof. At the same time, coloring plays not only an aesthetic role, but also gives the connection additional reliability. Coloring in this case is simply necessary. Upper layer allows you to fix a multi-layer patch, because asbestos cement sheets themselves porous.

Repairing damage with mastic

It is important to remember that at the joints, slate sheets are processed with mastic with a special reinforcing filler of a wavy structure.

Bitumen is melted in a separate container, after grinding. Foam and impurities formed in the process are removed. The melting process takes place at temperatures above 200°C until the bitumen is completely dehydrated. The grout consists not only of bitumen, a filler is added to the composition, which is preheated to a temperature of 110 ° C.

Hot mastic, using a spatula or other suitable tool, is applied to the surface prepared for repair.

Sometimes a kind of rubber paint for slate is used to restore damaged sheets. The tool has increased adhesive and strength properties. This method of slate restoration is gaining popularity.

How to use mounting foam to seal cracks in slate

Applying for recovery mounting foam, slate is pre-cleaned and degreased. Foam is blown into the resulting crack, but some free space is left for the sealant, which, after the foam has hardened, is squeezed out in a dense layer over the foam. Bituminous mastic is applied over the patch that has formed, which helps to seal the crack in the slate and protect the interior of the attic from atmospheric precipitation.

Now you understand all the complexities of slate repair. How to repair holes and cracks - you know, you understand the details, but this is the main thing when carrying out restoration work with asbestos-cement sheets.

Slate is an asbestos-cement roofing material with a wide range of applications that has been in demand for many decades.

Even with the appearance of new analogues on the roofing market, slate remains the most popular among them.

Slate properties

Slate was invented over a hundred years ago. It is used in regions with both hot and cold climates. The service life of slate reaches 50 years, but in most cases 20-30 years.

Atmospheric precipitation practically does not affect the operation of slate.

One of the main properties of a slate roof is its small thermal conductivity. When the roof of the house is heated by the sun's rays, the climate under the slate remains quite comfortable. And in the cold season, has good thermal insulation.

Another very important advantage of slate is good sound insulation. Compared to metal roofs, it perfectly soundproofs the blows of hail, rain, and therefore you will practically not receive discomfort from showers and thunderstorms.

Slate - heavy and brittle material and this is its main disadvantage.

Material disadvantages

Reasons for the destruction of slate sheets

Asbestos cement slate is a rather fragile material, and it is often

Often problems arise precisely because of incorrect fasteners, therefore during installation, it is very important to follow the installation technique. Do not pierce the sheets with nails, and before installation, you need to drill it in the attachment points.

When the lathing is done correctly - there is no sagging and the step of the lathing is observed, then the roof will serve for many years.

During operation, the slate is constantly exposed to negative factors. environment, which affects the condition of the roof is not the best way.

NOTE!

The main reasons for the destruction of slate during operation are sagging from heavy snow masses. Also a negative factor is stagnant rainwater falling on the roof of the branch.

As a consequence of this microcracks appear, which further lead to the destruction of the coating. Also, slate can be spoiled by mosses growing on it, lichens, they release acid-containing substances that destroy it.

How to detect coating defects in a timely manner

Leaks are very undesirable consequences of a violation of the roofing system. They appear from various kinds of damage:

• biological;
• Mechanical influences;
• weather conditions.

To prevent roof leaks, from time to time it is necessary to inspect the slate. Common defects in slate roofs are chips on the surface and edges of slate sheets. Most often, the causes of repair arise due to the "aging" of the material.

Slate repair - how to fix a crack in the slate on the roof

If you still need to repair the slate, there is a crack or gap, there are many ways to repair.

So, how to fix a hole in the slate on the roof:

• First way: to seal cracks, you can make a special solution, it contains asbestos, cement, water and PVA glue. Water and glue according to 1:1, asbestos and cement 3:1. Stir to a paste-like consistency and apply to the crack (the crack should first be caulked).
• Second way: Can be used mounting foam for blowing cracks. After the foam hardens, the excess foam must be cut off, and on top of the cut, smear with sealant and a layer of roofing mastic for waterproofing.
• Third way: Aluminium foil often used as a material for sealing cracks in slate. The foil is folded in several layers, smeared with roofing sealant and applied to the area that is damaged.
• Fourth way: Can be used special silicone paste but it is very important that the surface is clean, dry and free of grease. After application, it is necessary to wait for complete drying. Only under such conditions will there be a waterproofing effect from the application.
• Fifth way: Available for sale ready mix putty, which are also used to cover cracks and seams and it costs less than silicone paste. To do this, it is enough to buy a ready-made composition. The surface must also be clean, dry and free of grease. Before application, the surface to be repaired must be primed with a conventional repair primer. After application, wait about six hours for drying, and if necessary, apply several more layers of the mixture.
• Sixth way: Applies also butyl rubber tape. It is easy to work with, because its surface is made of non-woven material, which is good if you need to stain in the future. It sticks to almost any kind of surface, withstands temperature extremes well and endures the negative effects of weather conditions.
• Seventh way: Seam sealing method hot bitumen. Bitumen is very easy to use. For putty, you need to take a piece of bitumen, heat it over a fire in a special bowl, stirring gently to 160 degrees. In this state, it can be poured into the cracks.
• Eighth way: Of the proven folk methods, the best is chalk with drying oil. We mix, cover the cracks, after drying, paint with oil paint. Ready!

Repair with rubber tape

Repair with bituminous mastic

If all the above methods did not help you, or the area in need of repair is too large, you need to think about replacing the sheet or the entire roofing material.

To replace one sheet of slate, you must:

1. Unscrew fasteners that hold the sheet.
2. First we take out the damaged sheet from under the neighboring sheet, under it we put a bar that will temporarily hold it.
3. Further attaching a new sheet into specially prepared holes.

When replacing one or more sheets does not solve the problem, or the slate is too worn out, then the slate coating is completely changed. To increase the strength, abestos-cement slate is painted with oil paint.

Use any oil paint, while it is possible to cover both old sheets and new ones. The paint that covers the slate should be liquid enough to lay down in a thin layer and be well absorbed. If necessary, it can be diluted with a solvent.

For a quality repair, be sure to clean the surface and degrease it. The primer contributes to a good adhesion of the material, so this step should not be neglected. Compliance with these simple tips will help to ensure the durability of the repair.

The cause of damage to the body kit may be careless driving, a traffic accident or hitting an obstacle. Damaged part spoils appearance car. Therefore, it is important to know what to do when the bumper cracked, and how to repair it yourself.

Depending on the degree of damage, the methods of restoring a damaged car body element also differ. Repair of cracks is carried out using:

• Putties

Small chips, scratches and microcracks must be covered with putty.

• Bonding

Allows you to repair small cracks.

• seals

It makes it possible to restore the body kit after receiving severe damage and the appearance of large cracks.

• "Welding"

A plastic patch is applied. The method is applicable in case of serious splitting of the bumper and the appearance of holes.

To carry out the work, you will need the following tools and materials:

• Building hair dryer and soldering iron.
• Brass mesh, staples from a construction gun, or metal tape.
• Wide and narrow spatulas made of rubber.
• Putty.
• Epoxy resin and fiberglass patch.
• White-Spirit, acetone, or alcohol based cleaners.
• Airbrush.
• Plastic solder.
• Primer.
• Grinding machine and circles to it, or a bar.
• Sandpaper of different grits.
• Mini drill or drill.
• Clamps.
• Paint in a can or spray can.

Bumper preparation

Damaged bumper, it is better to dismantle. This will allow for a more efficient and reliable repair. In general, the list preparatory work before restoring the body kit, it looks like this:

1. It is necessary to thoroughly wash and dry the body protective element.
2. The area of ​​damage must be sanded and sanded. You can remove the paintwork with a grinder. In addition to the directly affected area, grinding should be done 3-5 centimeters near the cracks.
3. Degrease the work surface. The procedure will need to be repeated after removing each layer of paint.
4. The edges of the cracks must be sharpened in the form of the Latin letter V.
5. Using a drill, drill a crack on both sides. This will prevent it from spreading throughout the part.

After the preparatory measures have been carried out, you can proceed directly to the repair.

The bumper must be thoroughly washed. To do this, use a soap solution. In some cases, automobile detergents. For drying, use such a tool as a building hair dryer.

Soldering large cracks

If the bumper burst badly, then it is soldered. The operation allows you to give a damaged part a second life. However, you need to know how to solder a crack in the body kit. The operation is carried out in stages:

1. Fixing the two parts of the body kit. Clamps are used for this. Two surfaces to be soldered are tightly applied to each other and securely fixed in this position.
2. Soldering on the outside of the bumper. Do not leave large gaps between stitches.
3. Reinforcement of the damaged area. It is carried out from the inside of the bumper. A mesh or staples are soldered into the structure. This step allows you to increase the strength of the weld.

For soldering, it is recommended to use a powerful soldering iron (at least 100 W). The tool must be held in such a way that it does not burn through the plastic. It is also worth buying a device with a wooden handle (the plastic one will melt after the tool has been used for a long time). For more precise soldering, the tip can be sharpened and cleaned.

After soldering, the body kit is ready for further operation. Only, it remains to give the restored part an attractive appearance.

Using a hot air gun

When repairing severe damage, use a building hair dryer. With its help, the edges of the cracks are melted, as a result, a strong and reliable weld appears in place of the burst part of the body kit. To make the design more durable, use plastic strips 1 cm thick. They can be purchased separately, or cut from an old donor body kit.

When soldering, use the same type of plastic that the bumper is made of. Otherwise, the seam will turn out to be non-monolithic, which will lead to an early destruction of the structure.

The method is effective in the absence of some parts of the body kit, serious cracks and holes.

Bumper bonding

Small cracks can be sealed. This do-it-yourself bumper repair method is most popular with motorists, as it is technologically simple and effective. As an adhesive, special glue for plastic, acetone, and liquid plastic are used. To obtain a polymer seam, a two-component 3M composition is used.

When gluing, it is necessary to fix the bumper tightly, otherwise, the halves may be displaced and the symmetry of the part may be violated. You will need to wait until the adhesive is completely dry.

Gluing with acetone is performed as follows: a substance is applied to the crack, as a result of which part of the plastic dissolves, forming a strong seam. Later, it is treated with an adhesive from 3M. Allow to dry and mask the traces of body kit restoration.

Alternative! Medium damage can be sealed with a mixture of glue and soda. To do this, you need to tightly connect the split parts, pour soda along the entire length of the crack, and apply glue to it. As a result of a chemical reaction, a strong seam is formed.

We went into the bathroom, and there is a puddle on the floor next to the ceramic toilet, and you are completely unaware of what it could be? If the gasket at the entrance to the drain tank is leaky, work for a couple of minutes, another thing is when the problem arose due to a crack in the same tank or the bowl of the plumbing fixture itself.

In this case, not so easy work is ahead, which can even end with a complete replacement of equipment. If you want to know how to close a crack and how you can glue the toilet yourself, read our article further.

What could have happened

Before we learn how to seal a ceramic toilet, let's understand where our crack came from, so as not to waste time in vain.

Falling objects	In a cramped bathroom in a city apartment, everyone wants to make the most of its space. Therefore, over the toilet bowl, a cabinet is often installed with different household chemicals and often with tools. By negligence, they can fall into the toilet, because of which it will immediately crack.
Sudden temperature drop	Ceramics do not like sudden changes in temperature. In this case, an uneven expansion of the material is created, due to which internal stresses increase in it. The result of such actions is a crack. This can happen due to a faulty mixer, when pipes with cold water hot will come out. Plastic parts will begin to deform. After that, cold water will rush again, which may cause cracks, and you will have to think about how to seal the toilet bowl.
Incorrect assembly	Do not apply force in large quantities during the process. Make sure the bolts are evenly tightened. Otherwise, these two conditions will become harbingers of the appearance of cracks. In this case, the tank and the toilet can burst after a while, even a very long one.

1. Close the toilet lid. A seemingly simple operation will help protect the bowl from foreign objects that can cause chips and cracks. In addition, your valuables will also not fall into the water.
2. Do not pour hot liquid into the toilet, be sure to let it cool. Agree, the purchase of a new toilet and its installation will cost much more than an old pot or pan.
   This also applies to winter. Do not direct water at a temperature of 80-90˚ into the toilet bowl.

Tip: if there is no other way to remove water from heating radiators, push the hose into the sewer riser.

1. During assembly, make sure that there are no distortions, and do not apply excessive force, remember that the product is made of clay, not metal or wood. If the toilet cistern is cracked, you will find out how to seal it in the article below.

So, we found out what can basically lead to cracks in a ceramic toilet bowl or cistern. Now let's move on to repairing them.

How to independently glue the toilet and drain tank

We use universal glue

This method will help repair the product when a fragment has broken off that is not related to ensuring tightness. For example, a part of the base and an eyelet for attaching a shelf.

Buy any generic adhesive from a reputable manufacturer, the price can't be cheap. Henkel's "Supermoment" is quite suitable.

The instruction is as follows:

1. Clean the surface of the defect from crumbs and dust.
2. Let the product dry completely.
3. Degrease surfaces with gasoline or acetone.
4. Apply glue and press the broken fragment. Fix in any way for the time indicated in the instructions for the composition.

Tip: the adhesive joint should not be loaded, as it will be much inferior in strength to solid faience.

Crack only outside

In this case, consider the moment when an object fell into the toilet bowl and damaged it. Universal glue is better to replace the two-component epoxy resin.

So, how to glue the toilet:

1. Prepare the components - resin and hardener, as well as a container for mixing them.
2. Dry the surfaces to be bonded well.
3. Close the water supply to the tank, install a fan, wipe off any drops. Make sure the bonding area is completely dry.
4. Degrease surfaces.

1. Mix the resin and hardener together according to the manufacturer's recommendations.
2. Apply adhesive to the surfaces to be bonded.
3. Be sure to fix the gluing area in any way. For example, you can use ordinary adhesive tape by sticking it on the outside of the bowl.
4. When the resin is dry, carefully sand down the glue lines where they are visible. First use sandpaper M20 or M40, then felt. Otherwise, pollution will accumulate here.

The crack is visible on both sides of the bowl

Now we will find out how to seal a crack in the toilet, which affects its tightness. In this case, it is also necessary not to allow the defect to increase.

Prepare:

• epoxy resin with hardener;
• drill with a thin drill bit for tiles;
• grinder with a stone disk;
• sandpaper and felt for grinding the gluing area.

It remains to learn how to seal the toilet with your own hands:

1. Drill 2 thin through holes at the ends of the crack. So you stop its lengthening.
2. Using a grinder, select a recess along the entire crack by about 50% of the thickness of the faience. At the same time, do not forget that overheating the material will only aggravate the situation, it may begin to crack in other places. It doesn't matter where you do it - outside or inside the bowl, the crack will still be noticeable.

AT modern world it is difficult to imagine life without a toilet bowl, a cistern and other plumbing amenities. Of course, they need timely care. But, like everything in the world, plumbing can also sometimes break down, and then you have to repair it. Don't wait for your toilet to completely fall apart.

As soon as even the smallest malfunction, crack, do not postpone the repair, but begin to act.

Then your bathroom will last a very long time and in good condition.

If the toilet is cracked

Repairing a toilet, at first glance, may seem complicated, so many simply call a master who will do everything, but will definitely take some money from you. Perhaps this seems the only way out, especially if you have never encountered such problems before. And many simply do not know how to seal the toilet. But don't jump to conclusions. Try to repair the damage yourself, especially if the problem is that your toilet or cistern is cracked. After all, the crack can be glued. The main thing is not to panic and do the job carefully.

So, if you are faced with the fact that your toilet has cracked, then you first need to find out exactly where the breakdown occurred. And it’s not at all necessary to count how much money you have left in your wallet and remember where there is a plumbing store nearby, because you can fix this problem yourself with the help of improvised means. Consider the moments when you have a crack on the toilet bowl, drain tank, or if a piece of ceramic has broken off from them. All this is fixable if you approach this matter correctly.

Toilet drawing.

If your toilet has a crack, it needs to be sealed as soon as possible. Firstly, so that it does not become even larger, and secondly, so that water does not seep through. To seal the crack that has formed on the toilet, you must have glue. It must be waterproof. You can also use cold welding or silicone sealant. Find sandpaper and a spatula. Well, if you also have a building hair dryer.

When you have found everything you need for repairs, you can go directly to it and proceed. Take a building hair dryer and warm up the crack. This must be done not only outside, but also inside. Such actions are necessary in order for excess moisture to evaporate. It is necessary to degrease the surface on both sides. To do this, use either acetone or solvents. Next, gently coat the surface with epoxy. Then stick strips of plastic on both sides and wait for everything to dry. And at the very end, it is necessary to apply waterproof glue to the crack.

But it happens that a piece of ceramic just broke off from the toilet bowl. Then you will need glue, which must be waterproof. Apply a thin layer of glue to the broken piece, press it to the place from which it broke off, and after four hours it will stick. Next, process the seam that you have formed with seam putty or epoxy with filler. After that, it is better to clean that place with sandpaper.

Solving the problem with the drain tank

If the problem is that it was the drain tank that cracked, then you need to determine exactly where the crack is. They usually appear on the walls of the toilet bowl. This is due to the fact that mechanical impacts most often occur on the walls. Having decided to repair the tank, you need to make sure that the water is blocked and there is no water inside it. Next, you need to carefully open the lid of the tank (after all, if you break it, you are unlikely to be able to find the same one) and dry it completely. And only after these steps can you treat the crack with a sealant and wait until it dries.

Now you need to try the drain tank. To do this, try to draw water into it and wait until the tank is full. And after that, you can see if it is leaking or if your efforts were not in vain. But, if, nevertheless, after your actions, the tank leaks, then in this case you will have to change it. This rarely happens, basically, it can be repaired by yourself, even if it is cracked.

Plastic buckets, canisters and tanks - things on suburban area necessary. Often, in the conditions of a summer residence, it is not possible to change an old bursting plastic container for a new product, but, if desired, it can always be repaired. How this can be done is described below.

If the bottom of a plastic bucket has burst, then it is useless to try to seal it. No glue can withstand the long-term pressure of the liquid poured into the container, and over time, the crack on the plastic will definitely open.

It is much more reliable to repair a broken bucket by sealing a crack in it with another suitable piece of plastic.

For this you will need:
large and powerful soldering iron;
plastic tape, which, for example, can be cut out of an unnecessary PET bottle, or a plastic tie;
any detergent.

It is necessary to solder the crack both inside the bucket and outside, and it is recommended to start from the inside, since there the edges of the crack can be superimposed on each other quite tightly, resting them against the surface on which the bucket stands.

If you start work from the outside of the crack, then its edges will spring, fall through and it will be difficult to impose them tightly on each other.

However, for convenience of perception, let us consider, after all, how a crack is sealed on a plastic bucket from its outer side, bearing in mind that it is already closed inside the container.

So, in order to solder a plastic bucket:
1. Its surface around the crack is thoroughly washed and degreased.

2. Turn on the soldering iron, wait for it to warm up and move its tip along the crack with smooth movements to the right and left, without pressing on the plastic so as not to burn it. Thus, melting the plastic at the edges of the crack, the tip of the soldering iron passes along its entire length.

3. Sequentially lay the plastic tape on the crack, starting from a point slightly further than its beginning. At the same time, the tape is heated with a soldering iron so that the melted plastic fills the crack cavities, that is, figuratively speaking, it is soldered.

4. After soldering, the cracks get a seam, which is additionally smoothed out with a hot soldering iron, moving its tip along this kind of “welded” line.

This is how easy and without any special tricks you can solder a crack on a plastic bucket or any other container made of plastic. Inside the bucket, the seam is made using the same technology.

It remains only to check whether it leaks after repair.
