Fiberglass painting specifications. Painting fiberglass: varieties, application features, installation. What glue to glue fiberglass

Painting fiberglass gossamer - a popular option for repair and finishing materials fiberglass. You can recall another similar material, the so-called fiberglass wallpaper - but this is a ready-made finish and it is suitable for even walls. And if the walls need to be leveled, cracks removed, then the fiberglass gossamer will cope with this better and faster than plaster. It is a thin (25–50 g/sq.m), opaque and pliable canvas, which, thanks to its texture, perfectly strengthens and levels the walls before painting.

How is fiberglass cobweb made?

Despite the name, fiberglass gossamer is not woven. Fiberglass consists of glass fibers, which, according to the technology, are distributed and joined together by pressing with an organic resin additive. The canvas undergoes crystallization, and it is easy to twist it into a roll. In this form, packed in a shrink film, the gossamer is delivered to the consumer.

Why do you need a fiberglass web?

Fiberglass gossamer as a new generation material meets modern requirements for wall repair. In addition to good plastering properties, a fiberglass sheet creates a reinforced, non-collapsing layer on which painting or wallpapering can be carried out. And this is done, unlike a number of plastering and painting works, quickly - by sticking to the wall.

The finished result is a flat surface: textureless, rough, resistant to moisture and mechanical damage, environmentally friendly, breathable and fireproof. And, most importantly, durable - it can be repainted over and over again at will.

Where can it be applied?

Manufacturers recommend cobweb fiberglass for already plastered walls and ceilings, or lined with drywall. Fiberglass can successfully replace the finishing putty. Especially on surfaces that are prone to cracking: the gossamer will prevent cracking and the formation of damage and flaws - that is, all those imperfections that we usually see on walls prepared without fiberglass layers.

The use of cobwebs is relevant when walls need additional reinforcement and strength without increasing the load. And also if it is necessary to hide the joints between the slabs, in particular, gypsum boards (which, when stored in a warehouse, absorb excess moisture and deform when dried).

It is advisable to use the web in new buildings: it prevents wall and ceiling defects that form after shrinkage, greatly simplifies the maintenance of surfaces and guarantees their long-term operation.

Due to its properties, fiberglass perfectly serves in rooms with high humidity: kitchens, bathrooms, sanitary rooms.

The material can also be used for roofing, wall reinforcement, pipeline protection, waterproofing and design purposes.

Why fiberglass is preferred: about the benefits

It is worth buying fiberglass from a specific manufacturer if the description of the material has the advantages described below. For example, German-made fiberglass gossamer "Vitrulan" is environmentally friendly and recommended for use in children's and health institutions. It can be guaranteed to be used for painting - unlike other brands, Vitrulan does not act as a roughness behind the paint layer.

The practice of using gossamer fiberglass shows that it has:

1. Resistance to the accumulation of moisture - water-repellent properties testify to this.
2. Resistance to damage - the surface cannot be scratched or punctured.
3. Fire safety - fiberglass materials do not ignite.
4. Reinforcing ability - the fibers of the canvas after it is glued to the surface do not stretch and create a monolithic layer.
5. Environmentally friendly - gossamer fiberglass consists of substances that are involved in the manufacture of glass, therefore it does not contain harmful compounds, is not an allergen, and does not enter into chemical reactions with the environment.
6. Vapor-air permeability - the canvas "breathes", that is, it allows air and steam to pass through, preventing the development of mold and fungus, and waterlogging of the premises.

Fiberglass is convenient to transport and work with: the gossamer is sold in rolls of meter width and optimal (20 and 50) lengths.

The price of a cobweb for repairing walls for painting

Prices for a gossamer per roll 1m x 50m, i.e. for 50 squares from 278 rubles. per roll.

At its low price, fiberglass gossamer creates all the conditions for savings: it does not require an expensive amount of rough finishing and plastering. The cost depends on the density of the canvas and its length in a roll.

In any case, this is an ideal option for developers and customers. repair work who want to get effective results quickly.

The choice of glue for cobwebs

Traditional PVA glue is not suitable for gluing fiberglass materials - yellow spots may appear on the surface of the coating. You need to use a special adhesive recommended by the manufacturer. For example, Virtulan offers customers its own special adhesives and other related products.

You need to buy glue with a margin, counting on more consumption compared to conventional wallpaper. Dilute according to the instructions, taking into account the proportions - not thicker and not thinner than recommended, and then there will be no unexpected surprises.

How to use the web: conditions

When sticking, you must follow the same measures as for any wallpaper. Desirable:

• prevent drafts during work and until the walls dry;
• ensure dryness in the room;
• avoid direct sunlight on the canvas;
• maintain a constant air temperature.

Preparatory work

Surfaces (walls, ceilings) are prepared in the same way as for wallpaper, but leaving small cracks - they will be reliably closed by fiberglass and will not allow to increase. But if the cracks are deep and it is possible to apply putty with a spatula, then it is better to do this. After drying, sand with abrasive paper.

Thus, under the fiberglass, the gossamer requires a relatively flat surface, ideally treated with a deep penetration primer.

Cutting and gluing the first sheet

When unfolding the rolls, you should pay attention to the manufacturer's indication of where the front part is located. It matters even though both parts look the same.

The edge will have to be cut a little with scissors if the edges of the canvas are wrapped or damaged.

On the prepared surface with a roller or spatula, apply glue liberally (to the width of the roll). In contact with the canvas, the glue will quickly absorb, and there will be no excess that needs to be removed. The glue dries for about 15 minutes, this is enough time to adjust the first canvas.

You can cut canvases of any length, the main thing is to be comfortable. But if for walls the length can be solid, to the full height (plus 5 cm), then for the ceiling it is necessary to cut off pieces of one and a half meters. Otherwise, it will be inconvenient to work, and the canvas will stick poorly.

You need to work from the corner of the room. Applying to the smeared surface, smooth it with your hands, leveling it with respect to the corner, and spread the glue under the canvas with a spatula, removing air bubbles. The standard technique is from the middle to the edge, as is done with ordinary wallpaper. On the ceiling, it is better to glue the sheets along the room from the door to the window.

So, the sheet stuck securely to the surface. It is necessary to cut off excess centimeters if they are “formed”, and again coat with glue on top for better impregnation, distributing it with a spatula. If the canvas is evenly darkened from the moisture of the glue, it means that it is well saturated.

Shutdown

The next canvas is glued with an overlap - and glue, respectively, must be applied with the edge of the previous canvas captured. You need to work with the next sheet in the same way as with the first: stick, impregnate, press.

It is important to achieve the invisibility of the butt weld. To do this, you need to draw a line with the blade of a sharp knife - cut through both layers from top to bottom. Saturate the seam again with glue. The cutting line of the seam can be uneven, after finishing it becomes imperceptible.

In the corners, it is better to cut the canvas and paste patches.

Fiberglass may not hold back the gap in the event that the joining of the canvases takes place next to the assembly seam between the drywall sheets, and even more so along it. It is better if the seams of the wall and fiberglass are a couple of centimeters apart.

Canvas Safety

It is required to comply with elementary safety precautions: in work, use gloves, in which to fill the sleeves of clothing, put on a hat and a respirator. This precaution protects against getting the smallest sharp fibers of the material on the skin and in the respiratory tract.

Further processing can be carried out after the glue has dried - usually in a day. Before painting, the surface is puttied. In one or two layers - it's up to the master, it depends on whether you need to hide the texture and reduce the amount of paint.

In practice, puttying is often skipped and glue is applied liberally instead. The cobweb is great for repairing walls for painting, less paint is consumed, but the result is, so to speak, an amateur: when it dries, the structure of the cobweb appears on the surface, and smoothness cannot be achieved in the next series of paints.

Spider web for volumetric ceilings

A canvas made of pressed cobweb fibers allows you not only to work, but to create. At least this is possible with German quality materials. With Vitrulan fiberglass, for example, you can dream up using it for 3D format ceilings.

Once having become fashionable, over the years, the volumetric ceiling has only strengthened and developed design techniques. Today there are more of them thanks to modern materials. Cutting the fiberglass into pieces, sticking them on the protruding curved sections plasterboard ceiling, you can make a strong and durable surface of the shade that you need.

What if there is still a crack?

If the fiberglass is of high quality, like Vitrulan, then with strict observance of the requirements for laying the canvas, the surface will not crack.

But even if such a possibility is allowed, then the disadvantage can be eliminated quickly: with a patch from the same fiberglass. To do this, cut off a piece 4-5 cm larger than the crack and glue it over the putty. Cut with a clerical knife in the same way as the removal of the edge at the joints of the sheets. The line will thus be drawn through two layers of canvas and putty. Now you need to remove unnecessary trimmings (putty along with the canvas) and glue the patch into the resulting “bald” area. Then work again with putty - apply in two layers, i.e. straighten and sand.

If the fiberglass is damaged

It happens that the buyer came across a roll that was damaged due to improper transportation or careless storage. Edge damage will not affect performance in any way. The web can be glued even on curved surfaces. Therefore, you can cut off pieces in parts and glue them with an overlap.

Good results saving time and money

Perhaps you think drywall won't crack, or you want to line up the seams of reinforced concrete floors. In these cases, some cunning craftsmen suggest using fiberglass, cutting it into strips and gluing the joints between the plates with them. The stripes will not be visible after puttying and stripping. Of course, the seams must first be leveled with a gypsum composition, and then the fiberglass gossamer must be glued on.

However, after trying this method, you will understand why it is more reliable to strictly adhere to the technology, that is, a full-fledged sticker of fiberglass.

If you correctly paste and successfully paint the fiberglass gossamer, the walls and ceiling will be protected from cracking and emerging defects. This is an excellent solution for decorative plasters. A minimum of problems in the process of finishing work and a maximum of overhaul time - this is savings.

Not everyone knows what fiberglass for painting is: this innovative finishing material appeared on the market relatively recently and is actively gaining popularity due to its valuable properties. Like other types of modern materials, painting fiberglass gossamer gives previously inaccessible advantages in the process of finishing work.

Scope of material

What it is? Fiberglass is a non-woven fabric obtained by pressing and consisting of the smallest glass fibers. This is a thin translucent material, therefore, in professional jargon, fiberglass painting is often called a gossamer.

Why do you need painting fiberglass? It allows you to guaranteed to avoid visible damage to the walls and ceiling. The appearance of cracks on surfaces covered with plaster and putty is not always associated with the unprofessionalism of the workers who performed the repair. Cracking is caused physical properties traditional building materials which, under the influence of dry air, shrink over time.

Another reason for the appearance of cracks is the constant vibration characteristic of houses located next to a highway or railway. Due to the appearance of cracks, it used to be often updated decorative coating.

The use of fiberglass allows you to get perfectly smooth, durable and not subject to cracking walls and ceilings.

Hypoallergenic, Fire safety, ease of use, durability and the ability to pass water vapor, due to which the surfaces to be decorated have optimal moisture, cause the increasing use of gossamer for reinforcing walls and ceilings.

Specifications

Painting fiberglass is a light fibrous material obtained from natural raw materials, which is quartz sand.

The gossamer fiberglass is supplied in rolls, the length of the web is 50 m, the width is 1 m.

The density of fiberglass varies from 25 to 50 g/m 2 .

For walls, it is better to choose fiberglass of a higher density, and for a ceiling - less.

Application of the material is possible at temperatures from - 40 to + 60 ° C, which makes it suitable for any climatic conditions.

The web is breathable and hygienic: it does not electrify, does not accumulate dust, withstands wet cleaning, mold and fungus do not form on it. The material does not release into the air harmful substances and does not support combustion. All this, coupled with resistance to mechanical damage and the ability to quickly apply, gives the cobweb an advantage over other types of finishing materials.

Precautionary measures

Fiberglass gossamer forms a hard wear-resistant coating on the wall that can be washed, but it acquires these qualities only in combination with glue. Before talking about getting on the walls, you should take care of the precautions.

The material not yet glued is fragile enough, and its small particles can get into the respiratory tract. Once on the skin and mucous membranes, glass fibers cause irritation, so it is imperative to use a respirator, goggles and overalls when working.

It is possible to glue the cobweb only at a certain temperature (from + 15 to + 25 ° C) and air humidity not more than 60%. During the work, drafts are unacceptable, it is required to exclude direct sunlight.

How to glue fiberglass? It is necessary that the walls are pre-aligned and puttied. Before gluing, it is necessary to carefully putty and reinforce the seams between the plates and further ensure that they do not coincide with the boundaries of the glass sheets. Fiberglass is glued to the putty only after applying a deep penetration primer, which will avoid overspending of the adhesive.

The technology assumes that the cobweb can only be glued special formulations that do not contain starch, such as Bostic, Oscar, Wellton adhesives, produced by fiberglass manufacturers. The same compositions

It should be borne in mind that the material has a wrong side and a smoother front side: it is important not to confuse.

Sticking rules

You need to stick the material as follows:

• cut the material into strips, according to the height of the walls with an allowance of up to 10 cm;
• according to the instructions, prepare a solution from dry matter - the preparation time should not exceed 15 minutes (the finished solution is also sold, but it is much more expensive);
• evenly, without gaps, apply glue to the wall or ceiling - you need to cover the area with glue a little more than the width of the first canvas;
• strictly vertically, pressing with a roller or a flexible plastic spatula, glue the first canvas, - gluing starts from the corner closest to the window, the canvas is back to back;
• apply the next portion of glue and overlap the second canvas - in order for the paint to look even, the pile on the canvases should be directed in one direction;
• cut off the excess under the ceiling, above the floor and exactly along the joint with a clerical knife (to make it even, it is convenient to press a wide spatula to the borders and cut along its edge);
• cover the pasted canvases with glue on top - you need to stop when the color becomes uniform.

The video will tell you how to stick fiberglass sheets on the ceiling.

It is important that the room remains closed until the adhesive has dried completely. A draft can completely destroy the results of the work, causing peeling of the canvases.

How to prepare fiberglass for painting

Masters are often interested in questions: is it necessary to prime fiberglass, and is it necessary to putty fiberglass and why is this done? It is not necessary to prime the coating before or painting, because the walls have already been primed before gluing it. In addition, the adhesive acts as a primer.

The question of whether puttying is necessary does not have a definite answer. Fiberglass has a beautiful texture, which is sometimes preferable to keep, but the paint consumption will be very high and at least 4-5 layers will be required. The paint will make the joints noticeable: even if they are made perfectly, their very presence will by no means decorate the room. Puttying fiberglass before painting is better for another reason: small fibers can get into the air, which is harmful to health, and putty completely excludes their penetration.

What to putty? There is no special putty on fiberglass; you can use any gypsum or polymer-based finishing mixture, as long as it is of good quality.

How to putty painting fiberglass? The technology has some features:

• by the time the putty is applied, the glue must be completely dry;
• if the coating was pasted a few days ago, it must be cleaned of dust;
• the adjacent surface is protected with masking tape;
• putty is applied in two layers with an interval of a day;
• the thickness of the first layer should not exceed 2 mm;
• the second layer should be just as thin and completely overlap the first;
• after drying, the putty is polished with a bar with sandpaper with a grain size of not more than P150.

Puttying fiberglass allows you to get a perfectly flat, durable surface.

Fiberglass painting

How to paint fiberglass? If it is decided to paint fiberglass without prior puttying, no priming is required, but its texture will be visible even under many layers of paint. But still painted walls or the ceiling will have a more attractive appearance if they were previously puttied; in this case, a primer must be applied. To paint walls, it is better to choose water-based paints that adhere well and are easy to work with.

Fiberglass painting is carried out using the same technology as painting other materials.

The paint is applied with a roller until there are no uneven tone areas on the painted surface.

Is it possible on fiberglass? Yes, because this material is not finished. Fiberglass for wallpaper is a common finishing option, but the surface must be puttied and primed before final finishing.

Fiberglass is rarely used as a decorative coating, but as a reinforcing material it is indispensable. Its use will allow you to achieve a perfectly smooth surface, and cosmetic repairs will not be required much longer.

Hello to all readers. This time we will talk about fiberglass as a savior from cracks. We will find out what it is in general, what properties it has, what benefits it brings and, most importantly, how to glue it?

Painting fiberglass, or fiberglass "cobweb" (these concepts are equivalent) - this is not exactly glass wallpaper, although it is very similar to them. It, like them, consists of fiberglass threads, but these threads are connected not on a loom, but by pressing, much like paper. Fiberglass is thin translucent sheets that look like a "blotter". To the touch - quite smooth, but noticeably prickly - glass fibers after all. Canvas is sold in rolls, usually 1 meter wide, 50 meters long. When I saw him for the first time in my life, I thought: “Can THIS really reinforce something?” After all, it is very easy to tear it even with a finger until it is pasted. It turned out that it could.

The canvas is not afraid of water, fire, chemicals, mechanical influences, it does not accumulate static electricity and does not cause allergies. It turns out that he has all the advantages of glass wallpaper, which, by the way, are mentioned in the article about wallpapering. But it does not serve finishing walls, but only for reinforcing the surface of ceilings, walls, plasterboard boxes, etc. Exactly this effective remedy against cracks of all known to me. I without fail paste over all drywall constructions with it, as the most dangerous material in terms of the potential appearance of cracks at the joints.

Surface preparation, adhesive selection

Surface preparation for gluing fiberglass is done in the same way as described in the article about wallpaper. The only difference is that you can not close up small cracks, but glue directly on them. What cracks are considered small? I count the ones that the spatula blade can't get into. If the crack is wider, you need to repair it with some kind of strong putty, such as Uniflot, and sand it. Tools for work are also identical, only a seam roller is not needed here. For gluing, a special glue for glass wall paper is used, it is often put complete with a canvas. It is imperative to observe the proportion of water / glue indicated on the package, the glue should not be liquid. Its consumption will be serious, noticeably higher than when pasting with simple wallpaper, so you need to buy it with a good margin. And, I almost forgot - the windows on the day of work should be closed.

Sticking

Gluing fiberglass is easy, easier than ordinary wallpaper. By the way, I advise you to use a dense canvas - 45-55 g / sq.m. The glue is applied to the surface of the wall or ceiling, and it is applied boldly, because it will immediately be absorbed into the canvas, it will practically not need to be driven out from under the sheet. The canvases are cut for reasons of convenience: the full length can be cut off on the wall, and two running meters, more is already inconvenient. It is necessary to keep track of where the fiberglass has the front side - it is difficult to distinguish by sight. Usually his “face” is directed inside the roll, but it can be anything, carefully read the label. By the way, I advise you to use a long sleeve, gloves, a respirator and a hat - glass fiber particles will fly all over the room, prick the skin, and, God forbid, get into your nose - you will sneeze for a long time. But this is only in the process of gluing.

So, they applied a wide fat strip of glue, for example, to the ceiling. We take our first canvas and apply it to the surface, leading the edge along the corner, and smooth it lightly with the palm of our hand over the entire area. That's it, the sheet is stuck, now you need to expel excess glue and air from under it with a wallpaper spatula, it's very simple, we make movements from the middle of the canvas to the edges. As soon as the job is done, we cut off the excess against the wall, again we take a roller or brush and cover our sheet with glue. Yes, yes, this is a must, the canvas must be completely saturated with glue, and in order to achieve this, you must again rub the glue into the canvas with a wallpaper spatula, as if puttying it. It is clearly visible to the light whether the canvas has been soaked; when it is well saturated, it is darker. We rub the glue until our entire sheet becomes a uniform tone and wet to the touch.

We cut the second canvas. It is better to glue them along the room, overlapping. We glue the strip behind the first sheet with a slight approach to it. We stuck the second sheet, expelled glue and air from under it, now we take a sharp clerical knife and cut the overlap through two layers, removing excess from above and from under the sheet, thereby obtaining a perfect imperceptible seam; and then soak it well. We will do the same later with longitudinal joints. The evenness of the cut does not matter - the seams, although they will be visible to the eye, will not be felt by the fingers at all, which means that we will not get any drops on the ceiling in the future. On internal and outside corners we always cut the canvas, unlike simple wallpaper, at least, because it will tear anyway. Do not press hard on the knife. Our hero is very easy to cut.

Fiberglass dries completely, usually in a day. Someone immediately paints it. I would not advise doing this, but would advise to putty (at least 2 layers) for painting. Firstly, if you immediately paint on the canvas, the paint leaves immeasurably, it simply soaks into it. Secondly, no matter how many layers you apply, the texture of the fiberglass will still be visible, and this does not look very cool. After puttying, the usual-looking smooth ceiling is obtained, which already looks much better after painting.

Despite all the advantages, the hero of this article has weakness. This place is the seams. If the crack under the canvas runs parallel to the seam between the sheets and is closer than 1 centimeter to it, it will come out. Moreover, it will come out along the seam between the canvases, even if the crack is not directly under it. This can happen in the case of a plasterboard surface, if by chance the joint of the canvas coincides with the joint of drywall sheets, as in the photo:

Therefore, I always photograph the surface of a wall or ceiling made of HA before plastering it under fiberglass. So my seams will definitely not match, and there will be no cracks.

If the crack nevertheless slipped upward, it is easy to fix it once and for all. To do this, you need to glue a piece of canvas of such a size directly on top of the putty directly on the glue that it covers a space of at least 3 cm from the crack in all directions. Cut it around the crack with pressure right through the putty, then peel and remove the putty in this area right with the canvas that was under it. As a rule, when wet, it is removed quite easily if you pry with a knife. Our ready-made patch is glued to this place, which automatically fits perfectly on the site in shape. After that, you need to let the canvas dry and putty the place of repair again with 2-3 layers.

Perhaps that's all. Subscribe to updates if you want to be the first to know about new articles. And good luck with the repair!

In rooms with high level patency, decorative functions and high wear resistance of finishing materials are important. The simplest and most economical option is pre-gluing the walls with fiberglass, and then painting them.

Before starting work related to the use of fiberglass, you will have to carry out work, including puttying, priming. As soon as the plastered and primed wall is completely dry, you can continue to work, that is, proceed to decorating the walls with fiberglass.

What is fiberglass?

Painting fiberglass is called environmentally friendly modern material, based on mineral fiberglass and certain organic resins. This non-woven solid fiber does not have a pronounced pattern, which is characteristic of glass wall paper, in it the glass fiber threads are arranged in a chaotic manner.

Fiberglass has an acceptable cost, it is often called fiberglass, a common name is “spider line”, since this material has a soft and pleasant texture. There is a division of this material into different classes depending on the density (thickness).

The cost of fiberglass depends on the density, as well as its performance characteristics. Professionals recommend choosing fiberglass for arranging the surface of the ceiling to take several different classes at once, that is, in the range of 25-35 g / m 2, getting a guaranteed light and reliable coating.

If the density of fiberglass is higher, it will be able to withstand significant mechanical loads, no unpleasant cracks and deformations will form on it.

It is an erroneous opinion that cullet and gossamer are one material. - rolled decorative coating, which is produced by weaving from fiberglass.

Fiberglass is a special material obtained by pressing fiberglass threads for decorating walls. Fiberglass does not have a special pattern, so it can be painted an unlimited number of times. In terms of cost, the difference between fiberglass and glass fiber is 2-2.5 times.

Material Advantages

• increased fire safety;
• durability;
• heat resistance;
• durability.

Do not miss the opportunity to use them in your modern and stylish interior.

Work order

Let's try to understand the subtleties technological process and also give some useful tips those who want to perform these actions on their own and means.

1. First you need to cut a roll of fiberglass, cut into several pieces of the required length, not forgetting about 10-15 cm allowances to match the pattern. Do not forget that the fiberglass Gossamer is painted after gluing, the canvas must retain a certain pattern, otherwise there will be all joints are visible, the aesthetic characteristics of the surface will be violated. To glue the first piece of fiberglass, you will need a building level.



2. All subsequent pieces of fiberglass are glued end-to-end, in case of damage at the ends of the web, overlapping is performed. If you have chosen the method of gluing fiberglass cloths with an overlap, all damaged edges after gluing will have to be cut off, thus obtaining a completely even joint.
3. Next, the glued web is evenly smoothed with a wallpaper spatula.

How to glue fiberglass on the surface of the ceiling and walls

Special adhesive for fiberglass

1. For gluing fiberglass, you will need a special glue, on its label there should be information that this glue is suitable for working with fiberglass.



2. The glue must be made by a reputable manufacturer, otherwise you cannot be sure of its quality.



Also note that you will have to apply the adhesive directly to the walls or ceiling, not to the fiberglass.

It is important to start pasting in the direction from the light, that is, start from the wall that is near the window. Masters with fiberglass skills recommend using a material whose density is 25 g / m 2.



If an inexperienced builder purchases fiberglass of a higher density, there is a high risk that after a while it will simply fall off the wall.



When pasting the ceiling or walls with fiberglass, the windows in the room must be closed, that is, drafts are not allowed. It is advisable to carry out any work related to gluing fiberglass to the ceiling (walls) in special protective clothing, for example, use gloves and a robe.



Otherwise, there is a high risk that irritation will appear on the skin, allergic reactions are not excluded. You can use a respirator to protect your respiratory organs from dust.



Fiberglass can be painted only after it is completely dry. Want to see the fiberglass texture? In this case, apply no more than two coats of paint to the walls, all before gluing the fiberglass to the wall surface.

Painting fiberglass, called the "spider web" due to its external similarity with the spider's network, is widely used as a finishing and at the same time reinforcing material when performing interior work.

The use of a fiberglass-based canvas eliminates the formation of cracks during the drying of the plaster and the shrinkage of the building, and simplifies the preparation of plasterboard walls for painting.

As a result, it is possible to achieve a higher quality finish on walls and ceilings.

Choosing glue for paint cobwebs

Fiberglass is glued to a special glue for glass. The most popular among professional finishers are adhesives of the following brands:

• OSCAR is an acrylic-based universal dispersion adhesive. Designed for gluing fiberglass painting canvas and glass wallpaper for painting on various surfaces(concrete, brick, drywall, OSB, etc.).

Glue Oscar for fiberglass gossamer is available in the form of a ready-made solution, as well as in the form of a dry powder.

The composition of the adhesive includes an antiseptic additive that prevents the formation of mold in rooms with high humidity. The adhesive is applied directly to the surface to be pasted, which facilitates the workflow, the high elasticity of the composition allows you to adjust the position of the canvas.

• BOSTIK 70 is a modern adhesive based on water dispersion (PVA) and starch. Designed specifically for gluing gossamer, glass and fiberglass.

Suitable only for dry rooms. Works great on both absorbent (drywall, chipboard, concrete, brick and plaster walls) and painted surfaces. Bostic glue for cobwebs is sold ready-made, in plastic 15-liter buckets.

• Nortex is a universal adhesive based on modified starch with the addition of an antifungal component. Produced in a dry and ready-to-use form, suitable for all types of cullet (fiberglass).

When dry, Nortex becomes colorless and leaves no stains. The sticker is dense "cobwebs" is made immediately after applying the adhesive to the wall.

Step-by-step instructions - how to glue a cobweb on the ceiling and walls

Painting fiberglass is the most affordable and most effective material for dealing with cracks in walls and ceilings.

It perfectly masks the joints of GVL and KGL sheets, making the surface monolithic and more durable.

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

• primer (you can use ready-made glue for fiberglass);
• roller for applying glue to the wall;
• a clean, dry cloth to remove excess glue;
• plastic spatula for leveling wallpaper;
• a construction knife with replaceable blades and a wide metal spatula for cutting wallpaper;
• ladder;
• respirator (to prevent fiberglass particles from entering the lungs).

Working with a "cobweb" in complexity does not differ from the process of gluing ordinary wallpaper without fitting and takes place in several stages:

1. Surface preparation. First you need to clean the wall / ceiling from dirt and peeling plaster, putty large flaws, if any, and prime the surface with a latex primer or a weak solution of glass wallpaper glue.

1. Applying glue. With a fluffy roller or a wide brush, apply the adhesive to the wall or ceiling (approximately one glass of glue per 1 square meter of wall). It is desirable to apply glue on the surface to be treated with the expectation of 2-3 strips of canvas.

1. On a wall/ceiling evenly covered with glue, a “cobweb” canvas is superimposed and evenly straightened so that there are no wrinkles and bubbles. It is convenient to expel air from under the wallpaper using a wide plastic spatula, moving in a herringbone pattern (from the middle to the edges). Then, in the same way, the second strip of fiberglass is glued end-to-end with the previous one.

Which side to glue the cobweb? Indeed, fiberglass has two sides, the wrong side and the front. You need to glue the wrong side - the one that has a more fleecy structure.

Second way: Unfortunately, it is not always possible to join two fiberglass sheets perfectly evenly, especially when the edges of the canvas are damaged.

In this case, the cobweb is glued in a different way - overlapping, followed by cutting two canvases with a construction knife.

To achieve a perfect joint in the center of the resulting overlap, both layers are cut with a sharp knife and the cut strips of both sheets are carefully removed.

FAQ

On what surface can you glue the "cobweb"?

Virtually any - concrete, wood, drywall, plastic, cleaned brickwork etc. The most important thing is to prepare the walls and ceiling - putty large holes and cracks, remove all protruding bumps and primer.

What is the consumption of glue for fiberglass gossamer?

Dry glue like Oscar will need about 400-500 grams per 50 square meters"webs". The consumption of finished glue is about one liter per 5 square meters of fiberglass.
