Finishing of external walls on a grid. Overview and advice on choosing reinforcing meshes for wall plastering. Technical nuances of installation and overlay

Not a single repair is complete without leveling the surfaces, the plaster additionally serves as protection, heat and sound insulation, thereby performing non-aesthetic and practical functions. For the reliability and strength of the rough finish, a grid is needed for plastering walls, ceilings, floors, which fixes the leveling layer, prevents the mortar from peeling and cracking.

Scope and types of reinforcing mesh for plaster

Previously, shingles were used to fix the plaster, nails were often stuffed, later a chain-link appeared. These traditional technologies have been preserved to this day, and along with them, new materials have appeared that significantly improve the quality of the rough finish, facilitate and speed up the repair process. Today, reinforced mesh for wall plastering is presented in a wide range and its choice depends on the type of mortar, layer thickness, application area: exterior or interior decoration, and operating conditions: microclimate. Plaster mesh is the basis of the leveling layer, which makes it reliable, resistant to mechanical stress, able to withstand difficult chemical and biological operating conditions. Prevents flaking, bubbling and cracking of the solution.

What are the grids for plaster - choose not to be mistaken

High requirements for the quality of repairs, new technologies in the preparation and finishing of surfaces, a variety of mortars based on cement, lime, gypsum with the addition of additives forced the construction market to respond with new auxiliary materials. Used for different purposes different types plaster mesh.

metal

Traditionally, plaster metal meshes are used as a reinforcing layer: welded, woven, made by expanded metal.

Steel mesh for plastering walls, it happens with cells of different sizes. It consists of metal rods of different thicknesses, soldered by welding at the intersections. Very durable product, with high physical and mechanical characteristics, but only suitable for interior decoration in rooms with a dry microclimate, as under the influence of humidity, corrosion can form on the grid, which will lead to the destruction of the plaster layer.

Welded grating - an indispensable solution for thick layers of finishes

Galvanized mesh for wall plastering is the most popular option for exterior facade and basement works, it is not afraid of corrosive deposits. Cells from small to large, fixed in knots by welding.

Reinforcing mesh for wall plastering - chain-link, universal for a thick leveling layer, suitable for all types of mortars. Thanks to the movable wicker knot system, it can be used not only for finishing surfaces made of brick, concrete, stone, but also for aerated concrete and wooden walls where the material is constantly working under the influence of climatic conditions. In addition, the chain-link is relevant in new buildings, where wall shrinkage is inevitable.

Rabitsa - traditional way reinforcement for plaster

Expanded metal mesh for wall plastering is made in a special way. Holes are cut out from a whole sheet of metal under a press, then the web is stretched to obtain diamond-shaped cells. The absence of welded joints gives the product strength; expanded metal mesh for plaster is used internal walls, under a thin layer up to 30 mm.

New technologies

Along with metal products, meshes made of modern, synthetic materials are widely used for the manufacture of a reinforcing frame for a leveling plaster layer.

For aerated concrete and brick walls in the best possible way a plastic masonry mesh is suitable for plastic plaster with a small cell, for finishing facades and plinths with a larger one. It tolerates large temperature deltas, -40 o - + 100 o C, and is suitable for use on a heat-insulating layer.

Fiberglass mesh for plastering exterior walls and interior decoration is made of glass without alkaline impurities, an additional component is aluminum, which increases the mechanical strength of the fabric many times over. It is not afraid of chemical and biological influences, does not rot, is considered a universal material for all types of plastering work. Facade fiberglass mesh for plastering is made of extra-strong fiber, withstands thick layers of mortar, can be used for insulation.

Polyurethane mesh for plastering the facade and rooms is available with cells of different sizes, it is relevant for all types of mixture, it is possible to reinforce thin and thick plaster layers. The material is light, inert to different kind impact, the best solution for large areas, including industrial buildings, warehouses, private houses.

Biaxially oriented polymer networks - a new word in finishing materials. Lightweight, not subject to corrosive changes, alkali is not terrible, is not an obstacle to magnetic field, elastic, easily transforms to any base, therefore it is convenient for finishing curved and rounded structures. Polymer mesh for plaster is an indispensable solution for finishing conductive communications, facades and internal works. Heavy-duty polypropylene facade mesh for plaster withstands thick layers of heavy cement compositions, the use of the product in the reinforcement of bridges and roads only confirms the strength of the material.

Secrets of the masters

The variety of types of reinforcing meshes for plaster sometimes confuses home craftsmen who perform Finishing work with your own hands. There are a few simple rules that will help you figure out which grid and under what conditions it is better to choose:

• With a layer thickness of up to 30 mm, it is recommended to give preference to a fiberglass fabric punching cloth, it shrinks on a quick-drying mortar, and stabilizes the surface.
• Metal gratings are recommended for layer thicknesses of 30 mm or more. For outdoor work, as well as in baths and pools, galvanized products are relevant.
• The plastic grid is suitable for gypsum finishes, while the mini-cell sheet is suitable for finishing putty.
• For sealing seams and cracks - sickle, self-adhesive tape, it reliably protects the weak area, giving it strength.
• When reinforcing slopes under a thick layer of mortar, a metal grate should be used, with a thin layer - fiberglass, even if the thickness of the plaster does not exceed 5 mm, slopes with a width of 150 mm or more must be reinforced.
• For finishing furnaces, a chain-link is used for a cement-clay layer and fiberglass for thin plaster.

Convenient way to fasten and reinforce corners

Plastering a wall is not a complicated process, but sometimes there is a risk of the mixture running off. It is in such a situation that a reinforced mesh cannot be dispensed with. Although the question often arises whether there is a need for it. To make the finish of high quality and reliable, this is the best solution.

The plaster on the mesh sinks into the cells and no longer flows down. When such a coating hardens, it turns out reliably and durable. According to the masters, this method is becoming more and more popular because of its effectiveness. But you need to pay attention to some points, one of which is the application layer. If it is up to 10 millimeters, then the use of reinforcement is not required. If this thickness increases, then you definitely can’t do without an addition.

Which grid to choose?

Today there are enough offers on the market, for this reason it is not always easy to find the right one. To make a choice quickly, it is important to consider the characteristics. According to them, each person builds a choice and decides what will be effective. If there is no experience, then it is better to consult with the masters or study similar information.

To create a reinforcing material, manufacturers use a variety of components:

• Fiberglass. A unique modern composition that allows you to work with a small layer of plaster, making it as reliable as possible.
• Polymers. It is a plastic that is used in many industries today. It shows itself as one of the most reliable, but it does not weigh down the entire structure and is inexpensive.
• Metal. This is a classic that has been in demand on the market for many years. But at the same time, a metal mesh, the price of which is high (90 rubles per square meter), does not lose its leading position.

The choice is made depending on the construction process. It is not worth overpaying, as each type will have a price if it is not necessary. So before choosing, you need to understand what each of them represents.

Fiberglass

Today it is used often, because it is easy to use. This is a canvas with small cells, created from fiberglass. Plaster on a grid of this type is most often performed inside any room. Although in some cases it happens that they are used outside.

Experts highlight one main advantage - there is no need to level the walls before starting work. Such a canvas is attached to any surface, and plastering begins. Most often, a plaster finish appears on it. Since the work in the end turns out to be simple, a person without experience can take it on.

Polymers

Today, plastic is everywhere, and it is not uncommon in interior decoration. Polymer mesh plastering is fast and convenient. The fact is that such protection turns out to be reliable and comparable to metal, but at a price several times lower. Cost is the main stumbling block today.

The main plus is that the design does not receive a large load, but the reliability is not reduced. In hardware stores there is always such a grid with different cells and thickness. When it is applied, it is possible to easily level walls with a large deflection, up to about 20 millimeters. Plastering on a mesh of this format is a relatively easy process.

metal

The most common option today is a metal mesh. Because when there are large drops and holes on the surface, you simply cannot do without it. But the most common is the plastering of facades on a grid. And for efficiency, the mixture is made from cement. On sale, everyone will find several basic modifications:

• The use of thin wire is carried out by means of a woven system. Such grids are effective both inside and outside of any room. Basically, the cell dimensions of such a grid are 10 x 10 mm. The plaster mesh 10 x 10 is fixed easier than any other, because it is not very rigid. But during operation it shows itself as one of the reliable elements in the decoration.
• Chain-link mesh - it is wicker-reinforced. The price of a metal mesh is up to 200 rubles per square meter. It is often used not only in decoration, but also in any other construction processes. Works well in large areas. She has the size of one cell in standard terms slightly larger than the first (20 x 20 millimeters).
• There is another mesh manufacturing system - this is the welding of individual rods of various thicknesses. The application is extensive - they are mainly used to ensure that buildings or any structures do not precipitate during operation. Cells can have different sizes (the most popular is a plaster mesh 10 x 10 mm). Everyone chooses the right one depending on the type of work.
• Expanded fittings. It is created using a special technology, which gives it maximum strength. For this, a special machine is used, on which a metal sheet is stretched. In the process, cells of equal size are formed. As a result, the grid for plaster of this sample withstands a thick layer of plaster, and also gives strength to the created structure.

These are the main types that are easy to find on the market. But before you start, you need to decide what you need. The use of metal allows you to increase the bearing capacity and make the finish durable. Therefore, this method is considered the most common and high-quality. Working with each grid implies its own stages and rules. Fasteners specific, depending on the selected material.

Application of fiberglass

As already noted, such a mesh is light and it does not need to use a special type of fixation for it - a solution is quite suitable. To make it neat and even, it is slightly pressed with a spatula. For convenience, the mesh is cut into strips, but when laying, an overlap is made between them. If the site has an extraordinary surface, then any fasteners can be used for reliability. But after plastering they should not stick out. When finishing wooden structure latches can be staples from a construction stapler.

The use of other types

Polymer compounds are most often attached in the same way as fiberglass, because they have almost the same thickness. If this is not enough, then it is quite possible to cope with self-tapping screws. It is also necessary to overlap at the junction of the strips. The procedure is simple, but do not skip a few little things.

Metal mesh is used most often when you need to create a large layer of plaster. It is for this reason that it is important to securely fix the entire base. Only after that do the execution technology begin:

An important feature is that you need to achieve maximum tension without sagging of the material. If voids are formed in the plaster, this reduces its bearing capacity and all meaning is lost. The whole process of fixing the grid is simple, but you can’t skip anything. Every person without experience in applying plaster will cope with this procedure for short term. But before you start, stock up on everything you need.

How to set up beacons?

You can't do without them. When the grid is selected and located on the working surface, it is worth installing beacons, so to speak, guides for the rule. According to them, it turns out to make the layer as even and monolithic as possible. To make a rule, you need to take a small piece of metal profile up to one and a half meters in size, so that it is convenient to move it. Beacons are fixed with gypsum or any mortar that is in use. But the guides must be set strictly according to the level.

How does the finishing process take place?

According to the masters, if there is a grid of any design, then plastering usually occurs in two layers, although many experts increase this application to three.

Everyone must make his own decision depending on the condition of the surface. But the order is always the same and it should be followed:

• Applying the first layer is not difficult, because you just need to throw on the plaster. This requires a craftsman. The composition is taken on it and applied to the wall with a sharp movement. To do this, the mixture should not be too thick. Thanks to this process, the layer is obtained as durable as possible.
• As soon as the first begins to dry out, you can begin to impose a second. It should already be kneading tighter like dough.
• All work is carried out from the bottom up. After that, they begin to stretch the rule over the entire area, slightly shifting from side to side. This allows you to make the entire surface more even.
• But the third layer is done as needed. It is necessary to visually assess the surface - if something went wrong, then you can make a third application, but already thinner, just to even out the errors. The technology for performing plastering work is simple.
• When this is done, the beacons are removed, and the holes from them are smeared with the same composition.

Finish

This completes the plastering. In order for the surface of the treated area to be neat, it is worth making a finishing grout. The composition is taken more liquid. Such manipulations will not be difficult for anyone.

Conclusion

So, we found out how the plastering of the walls is done on the grid. As you can see, the materials can be different. But the technology of plastering on a grid is approximately the same.

Plaster is one of the most famous types of wall decoration. In order for the solution to last a long time and provide strength, it must be reinforced with a special mesh. In this article, we will take a closer look at the types of reinforcing meshes and tell you how to install them correctly.

Types of plaster meshes

Grids for wall plastering can be made of metal or polyurethane. They are glued to the wall with glue, self-tapping screws or screws. The canvas is sold in special rolls and has different dimensions, depending on the area of ​​\u200b\u200bthe wall that is being plastered.

There are a huge number of types of plaster meshes for plastering walls. Let's look at the main ones:

How to apply plaster

Depending on the method of applying the plaster, the reinforcing mesh can be fixed different ways. The first plaster layer is reinforced on top of the mixture, while it needs to be slightly pressed into the wall.

Advice! Before applying the last layer, we recommend fixing the mesh with special tools. If the area of ​​the wall to be treated is not too large, the mortar itself can be used as a fastener. To do this, apply the mixture at the attachment points, the entire wall does not need to be processed.

Which is better to choose

When choosing a reinforcing material for walls, first of all, evaluate the thickness of the future layer of plaster. You need to choose from the following options:

Plastic variant

When purchasing it for a wall, remember that the density must be more than 110 grams per square meter and alkali resistant. The minimum layer thickness is 3 mm and the maximum is twenty. Before proceeding to work, the rolls must be cut according to the area of ​​\u200b\u200bthe wall. They depend on the chosen placement method - along or across. If there are defects on the wall, it is better to place the material along the seams of the mortar. Make sure that the entire surface area is covered. It is better to trim with a margin of ten centimeters in order to further strengthen the seams.

Plastic Mesh Attachment Technique

The first step is to apply the first layer of plaster on the wall. Next, a plastic mesh is already superimposed, while it needs to be pressed as hard as possible. Then a second layer of plaster is applied. It is not necessary to wait for drying, plastering can be continued immediately. The plastic mesh should be placed in the middle of the wall. It can also be used for exterior wall decoration.

Most often, screws or brackets are used for mounting on the wall, and then they are already processed. But this method is only suitable for a thin layer of plaster. In this case, the grid will be located exactly in the middle. If the thickness is more than 10 mm, then it should be applied to the hats of pre-installed beacons. In this case, adjacent canvases will need to be placed with an overlap of 10 mm. And only after that it will be possible to continue plastering the wall surface.

When working with a plastic mesh, the plaster must be applied evenly. In this case, it is better to start from the middle of the wall, distributing the mixture in different directions. We recommend pressing the corners with a rule or a wide spatula.

Working with a metal structure

This option is used if it is planned to apply plaster more than 30 mm. The material is distinguished by its light weight, easy installation and, despite the metal base, quite good protection against rust. But, unfortunately, for outdoor work, the installation of such a canvas is not suitable.

First of all, the metal mesh will need to be degreased. To do this, it can be washed with water or simply rubbed with a damp cloth. The installation process consists of the following steps:

It will be necessary to apply the solution twice, and it will be possible to continue only after the first stage of the plaster has completely dried. It is applied using a trowel, the plaster is pressed into the mesh so that the mixture reaches the very wall. Then it is distributed over the entire plane of the wall with a spatula.

Plaster mesh netting

The chain-link mesh, or as it is also called braided, has a design with a cell diameter of two centimeters. This canvas is mainly used for reinforcing large areas or facades of the house. At the same time, the chain-link is perfect for outdoor work, due to its materials it is well protected from weather influences. The method of mounting on the walls is no different from metal installation. It is light enough that even a beginner can easily cope with such work.

Conclusion

As you can see, the reinforcing mesh has a positive effect on strengthening the wall surface. It will protect the plaster from possible peeling. This material can be used for both internal and external work. The installation itself will not take much time and effort, because the process is quite easy. The main thing is to follow the instructions given in the article, and the result will not be long in coming. We recommend watching the tutorial video:

Plaster is today one of the most popular materials for wall and ceiling decoration. Not so long ago, shingles for plaster were widely used to strengthen the surface of walls and ceilings. Today, it is increasingly being replaced by a reinforcing mesh for plaster. In order for the plaster layer to last as long as possible, it must be properly reinforced with a special plaster mesh. The mesh for plaster can be metal or polyurethane and is attached to the surface with glue, self-tapping screws, screws or other devices of the same purpose. As a rule, it is sold in rolls and can have different sizes.

There are the following types of plaster meshes:

• masonry mesh - plastic, made of a polymeric substance, has a mesh size of 5x5 mm, used for brickwork;
• mesh station wagon (small)- made of polyurethane, mesh size, 6x6 mm, well suited for reinforcing both finishing and plaster mixtures. It has wide functionality, allows you to carry out plaster work on any area;
• mesh station wagon (medium)- has the same structure as the small station wagon, cell size 13x15 mm;
• mesh station wagon (large)- differs in cell size - 22x35 mm, it is used for reinforcing large areas, such as warehouses, shop facades and other large structures;
• fiberglass mesh - its fibers consist of fiberglass processed in a special way, has a cell size of 5x5. Resistant to temperature and chemical influences, heavy-duty, can withstand heavy loads. This base is widely used for reinforcement and has almost no restrictions.
• Plurima mesh is a 2-axis oriented plaster mesh, made of polypropylene, has a mesh size of 5x6 mm. It is characterized by chemical inertness and lightness and can be used both for outdoor and indoor work.
• armaflex - polypropylene mesh, with reinforced knots, has a mesh size of 12x15 mm. Differs in superstrength, suitable for use in areas with an increased load of the plaster layer;
• mesh syntoflex- made of polypropylene, has a mesh size of 12x14 and 22x35 mm. Lightweight, chemical resistant. Can be used for interior and exterior decoration.
• steel mesh - basically it has steel bars that are soldered at the nodes, as well as a wide range of cells. It withstands the load perfectly, but can only be used for interior decoration, since steel is not able to withstand precipitation.
• mesh galvanized- is a network interwoven from galvanized rods, soldered in knots, has a wide variety of cell sizes. Differs in durability, is suitable both for external, and internal works, can be applied in any conditions.

Depending on how you apply the plaster (cover or spray), a metal mesh for plaster, or a plastic one can be fixed different ways. The lower plaster layer is reinforced with the selected mesh over the applied mortar of the required thickness, slightly pressing it.

The ideal option for applying the final - decorative or covering layer, is to first attach the rebar to a dry surface using special tools. If the surface to be treated is small, the fastener itself can serve directly. plaster mortar. In these cases, it should be applied pointwise, only to secure the mesh. After that, the required thickness of the plaster layer is evenly smeared over the entire surface.

What is the best plaster mesh to use?

When choosing a plaster mesh, the thickness of the plaster on the mesh always comes to the fore. It is necessary to calculate the lowest point on the ceiling using a laser or building level, then mark it and estimate the maximum thickness of the future plaster layer.

Depending on the result, you should choose one of the options:

1. If the thickness of the plaster layer does not exceed 20 mm, in the absence of rustication on the base of the ceiling, it is possible to apply plaster without a grid. We proceed directly to the installation of beacons.
2. If there are rustications on the ceiling, or the future plaster layer will be from 20 to 30 mm, it is advisable to use plaster mesh from fiberglass. The main purpose of such grids is to protect the surface from cracks.
3. With a layer thickness of more than 30 mm, you can not do without a metal reinforcing mesh. A metal mesh under the plaster will prevent it from peeling off the base under its own weight.
4. With an uneven ceiling, when the height differences can be more than 50 mm, it is better to completely abandon the plaster. In this case, it is easier to use a stretch or suspended ceiling.

Installation of fiberglass mesh

When buying mesh, remember that its cells must exceed 5x5mm, and its density must be from 110 to 160 g/m2. In addition, the material must be alkali resistant. The minimum thickness of the plaster layer when using fiberglass mesh is 3 mm, the maximum is 30 mm.

Before starting work, the mesh is cut to size into canvases. The size of the canvases will depend on how you are going to arrange the grid - across or along. In the presence of rustication on the ceiling, the grid must be placed in one piece along each of the seams. If there are no rusts, then there is not much difference in the location of the grid, you just need to make sure that the entire surface is covered with a grid. It is better to cut off with a margin of 10-15 cm to strengthen the seams between the walls and the ceiling.

Glass cloth overlay technique

First, the first layer of putty or plaster is applied to the entire surface. A plaster mesh is applied on top of it, and then a plaster mesh is recessed, after which a second layer can be applied. It is permissible to perform this operation in one pass, or wait for the intermediate drying of the first layer. Fiberglass mesh, therefore, should be placed in the middle of the plaster layer.

Builders most often use screws and staples to attach the fiberglass mesh to the base, and then plaster directly over it. This method will be justified for a thin plaster layer (putty). The mesh in this case will indeed be located in the middle of the plaster. However, if the thickness of the plaster is 10 mm or more, the mesh will definitely be on the edge, while reinforcing not the plaster itself, but the surface.

It would be optimal to use the following order of installation of the plaster mesh:

1. Marking under the beacons, the holes should be drilled, and then the dowels should be inserted.
2. Installation and leveling of screw heads along each line of plaster beacons.
3. Application of the first layer of plaster along the width of the grid.
4. Through the heads of the screws, a mesh is laid on the fresh plaster. Nearby - an adjacent layer of plaster, on top of it a grid, and so on until the wall itself. It is necessary to place adjacent canvases on top of each other with an overlap of at least 10 mm.
5. Then the metal beacons are put on, and the plaster is applied over them as usual.

Mentioning the fiberglass mesh for plastering, it is worth noting that the solution should be applied evenly over the entire surface of the canvas, and smoothing should be started from the middle of the plaster mesh in opposite directions. The ends of the sheets at the corners must be pressed with a rule, or with a wide spatula. With a second spatula, the mesh is smoothed down the wall.

The sequence of actions when installing a metal reinforced mesh

Metal reinforced plaster mesh is used if it is necessary to apply a plaster layer of 30 mm or more. It is advisable to opt for a galvanized metal mesh with cells of 10x10 or 12x12 mm. Also suitable is a galvanized expanded metal mesh, with cells 10x25 mm. The mesh is very light in weight, with a minimum thickness of the plaster layer, it easily adapts to the surface, cuts well and will not leave rust marks.

Before you start working with a metal mesh, it must first be degreased. Galvanized mesh can be simply washed with water or wiped with a damp cloth.

Stages of work:

1. Cut the mesh into sheets using scissors for metal. The dimensions of each canvas will depend on how you are going to place the plaster mesh - along the ceiling, or across. In the presence of rustication on the ceiling, the mesh is located in one piece along each seam.
2. Using a hammer drill, drill 6 mm holes with a drill (drill). The depth of the holes should be 2-3 mm more than the length of the dowel. The hole spacing is 25-30 cm. So, with a step size of 25 cm per 1 square meter, you will need to make about 16 holes for dowels.
3. Insert the dowels into the holes, and then use the mounting tape and screws to fix the plaster mesh on the ceiling surface. Its edges must be securely fastened. We have an overlap of about 10 cm on one another, adjacent canvases. If the mesh lags behind the ceiling in some places, you will need to drill additional holes for mounting.
4. Install metal plaster beacons on the reinforced and stretched plaster mesh.

When applying plaster on beacons with a layer of 30 mm or more, it may be necessary to plaster in 2 layers with intermediate drying of the first. The first plaster layer is thrown onto the metal mesh using a trowel, pressing the plaster mortar so that it passes through the mesh and catches on the ceiling surface. Then the solution is evenly spread with a spatula or grater. The second plaster layer can be applied only after the first layer has completely dried.

When using galvanized metal expanded metal mesh, the minimum layer thickness will depend on the thickness of this mesh. For example, with a thickness of 0.5-1 mm, a layer of plaster of 5 mm is enough.

The mesh increases the strength of the solution when applied to large areas and transitions between different materials walls. Plastering the facade along the grid is necessary when working in new buildings, the walls of which are still sagging.

The reinforcing material can be metal, polymer or fiberglass. Its choice depends on the application.

What can be a grid

Often applied to concrete, brick and wooden facades the finish is cracking and peeling off. To prevent this from happening, the surfaces are reinforced with a mesh.

Woven

Woven mesh. This is a thin, but strong and flexible material, woven by weaving from wire of various sections. a grid with square cells 1 × 1 cm and a zinc coating. Sold in rolls.

chain link

A woven mesh or netting has a cell diameter of 2 cm, used to strengthen significant layers.

Types of metal meshes

Welded

Welded mesh has square cells. It is produced by spot welding of the intersections of the wire, the bars of which are located perpendicular to each other. The material is galvanized or polymer-coated light low-carbon wire. A welded mesh is used to prevent cracking of the finish during active settlement. We recommend using a grid with cells of 2-3 cm.

expanded metal

It is made on a special press from sheets of metal. The resulting material has diamond-shaped cells, which are staggered. Used for relatively. The rolls are 1m wide.

With a sufficiently thin layer of plaster, a mesh of fiberglass or polymers is used.

Facade plastering

Polymer mesh (price - from 2150 rubles)

Use a metal mesh when applying a finishing layer of 3 cm or more. The chain-link is not yet used for reinforcement.

Unroll the mesh roll. Measure the height of the surface from the roof to the ground with a tape measure. Cut the desired number of panels with scissors for metal.

Straighten and fix the mesh with screws or nails on the primed surface so that adjacent sheets overlap by 10 cm.

Mix the solution with an antiseptic. The latter will ensure that mold spots do not appear on the surface.

Throw the first primer layer of the solution with a spatula or trowel and level it with a rule. Let the mixture dry and apply a second leveling coat. It is thinner, so spread it with a trowel or large spatula.

If the mass lay unevenly, after it has completely dried, we recommend using a finishing putty. When it hardens, correct the irregularities with a fine sandpaper.

Polymer mesh is often used. It is resistant to chemical influences, so it does not spoil the finish coating during operation.

Measure with a tape measure and cut the mesh webs. If the base is dense, apply a thin layer of mortar and press the reinforcing material into it. If the walls are porous or wooden, you can fix the mesh with a stapler.

After fixing it, evenly distribute the mass over its entire surface so that the network does not look out.

Grid plastering - technology for working with polymers:

Start applying the solution from the middle of the canvas and continue to its edges, as if you were gluing wallpaper and expelling air from under them.

Note! Polymer meshes are elastic, so they stretch. Work carefully and do not allow the formation of bubbles from the reinforcement material.

Facing trim

The most common method of applying a top coat to both interior and exterior is to paint them. Before work, evaluate the quality of the base, repair cracks if necessary, make sure that the layer has a strong bond with the surface, does not peel off and putty the walls.

• After the putty has hardened, sand the surfaces with sandpaper. Before painting with adhesive paint, treat the area with a water-based primer. Pay special attention to the question of how to paint the plaster.

Note! If the finish is fresh, it may have an excess of alkali, so the use of solvent-based formulations is undesirable. When using organic solvent paints, be aware that the surface must be protected with a synthetic primer.

• Paint with a roller, carefully and without gaps, processing the entire surface. After the first coat of paint has dried, apply the second.

Advice on how to paint the facade plaster. It is better to use alkyd, acrylic and latex compounds for this purpose.

• Indoors second most popular top coat are wallpapers that also require careful preparation.
• Remove old wallpaper, if any. Before, make sure that it is firmly held.
• Rinse the cleaned surface with water and inspect for cracks. If necessary, cover with putty.
• Level the treated areas with sandpaper.
• Prepare wallpaper paste.

The rolls always have instructions for gluing the material and recommendations for the selection of glue. The technique of working with wallpaper on plastered walls does not differ from similar operations on other surfaces.
