Cracks at the joints of the gypsum board will not appear if you stick the fiberglass under the putty

It can be very upsetting when, after the end of a long and expensive repairs cracks suddenly appear on the ceiling or walls in those places where the joints pass between sheets of drywall or other facing material. To prevent this from happening experienced builders it is recommended not to be limited to a serpyanka mesh for reinforcing the seams, but to completely glue the surfaces with fiberglass with your own hands.

It is much easier to glue fiberglass than wallpaper, it takes a little time, but as a finish, you can be sure and not afraid that, due to shrinkage of the house or temperature changes, repairs will soon be required again. Let's find out what kind of material it is, how it "works" and what is needed for its installation.

Fiberglass

Fiberglass is a fiberglass non-woven material that looks like a thin blotter. It is produced by pressing, not by weaving fibers. By itself, it does not have strength, it breaks easily, but after gluing to the surface, subject to strict observance of the technology, it forms a reinforcing coating that is very resistant to deformation effects.

Fiberglass is sold in rolls of 45-50 meters with a width of 1 meter, and may differ in density. It has a front and a seamy side, which must be taken into account when installing.

The price of the material is low, depending on the density, a roll can cost from 300 to 1000 rubles. This is not something worth saving on since re-repair as a result of the appearance of cracks, it will be much more expensive.

Auxiliary materials and tools

Of course, the fiberglass itself will not stick to the wall, for this you need special glue and standard set tools:

• The glue is sometimes supplied with the fiberglass. If this is not the case, buy glass wallpaper glue - no other, including PVA or a composition for heavy wallpaper, is suitable;

Note. Calculating required amount glue, multiply the consumption declared for fiberglass by 1.5-2, since fiberglass is highly absorbent. In addition, the instruction requires the already glued canvases to be coated with an adhesive on top.

• To apply glue, which has a rather thick consistency, it is best to use a wide bristle brush on the surface;
• It is convenient to smooth the fiberglass with a special plastic wallpaper spatula, which experts call "shark fin";

Wallpaper spatula and the lines along which it expels air from under the canvas

• You will also need a sharp painter's knife and a long ruler or wide spatula for joining the canvas and trimming gaps.

Installation technology

During self repair many questions often arise.

In our case, the most important are the following:

• How to prepare a surface for fiberglass reinforcement;
• How to glue it correctly;
• Do I need to putty the fiberglass before finishing.

We will answer in this sequence.

Preparing walls for reinforcement

Before gluing the fiberglass to the wall or ceiling, the surface must be leveled with a putty (see Aligning the walls with a putty according to all the rules). This stage can be skipped only if it has already been putty before, the coating is even, strong.

Small cracks with a thickness of not more than 1 mm are allowed.

• Large cracks on the plastered surface are embroidered and sealed in several steps with putty or a special compound for joints;
• Joints between drywall sheets (see How to putty drywall joints according to technology) and other sheet facing materials, as well as the places of their attachment to the frame, are also putty, and the seams must be reinforced with a serpentine;

• After the “patches” have dried, the entire surface is leveled with a putty and sanded until a flat surface is obtained;

It often happens that the repair made does not please for long with an impeccable look. Painted or plastered surfaces are covered with a network of cracks, and the wallpaper begins to move away from the walls and become covered with “wrinkles”. To avoid similar problems allows preliminary preparation surfaces - reinforcement (strengthening), leveling, application of a composition to improve adhesion - a fairly large amount of work.

They can be replaced by gluing fiberglass based on fiberglass threads. It will help to strengthen the walls and ceiling, get rid of small cracks. The topcoat will lie flat, no defects will arise even if the walls of the building shrink.

The material is suitable for application in both residential and office, industrial premises. The main thing is to choose the right type of fiberglass.

Peculiarities

Fiberglass is used for rough finishing to prevent cracking finishing material, its deformation during shrinkage. The material is nonwoven sheets based on fiberglass filaments that are compressed. Material release form - rolls 1 m wide. Material length - 20 and 50 m.

GOST dictates different thicknesses of threads and their interlacing in a chaotic manner, which provides a reinforcing effect. The density of the material is 20-65 g / m2. Depending on the purpose of the material, rolls of one density or another are selected. Optimal for internal works is fiberglass with a density of 30 g / m2.

Due to its low density, the material looks like a translucent canvas, for which it received another name - "cobweb". Another name is glass-fleece.

A feature of the material is the presence of the front and back sides in it. WITH inside the front side is located, it is smoother. The back is more fuzzy for better adhesion to the surface.

Fiberglass can be attached to any type of surface, including for putty, painting, decorative plaster... Preventing cracking of the finish, the material allows the walls to "breathe".

Advantages and disadvantages

The main advantage of the material is the ability to eliminate cracks and deformations in the finish. Fiberglass has good adhesion, which ensures its tight adhesion to different types of surfaces.

The material is hypoallergenic, since it is based on natural ingredients(quartz or silicate sand), so it can even be used in childcare facilities. Thanks to good vapor permeability, it is possible to obtain "breathable" surfaces.

Among other "pluses" are the following:

• good moisture resistance, so the material is suitable for use in rooms with high humidity (bathroom, kitchen);
• fire safety, since the material is not flammable;
• not affected by fungi, mold;
• non-hygroscopicity of the material, due to which the optimal microclimate is always maintained in the room;

• does not attract dust and dirt;
• high density, which provides the effect of reinforcement and slight leveling of surfaces;
• wide temperature range of use (-40 ... + 60C);
• the ability to use on different types surfaces, apply for painting, putty, wallpaper;
• the ability to use on surfaces subject to increased vibration load;

• wide scope - in addition to strengthening surfaces, fiberglass, like fiberglass, can be used in roofing and waterproofing works;
• high elasticity and low weight, which simplifies the installation of fiberglass;
• light weight.

The disadvantage is the formation of the smallest particles of fiberglass, which appear during the cutting and installation of the blade. They can cause burns if they come into contact with the skin. This can be avoided by protecting the exposed areas of the skin, and the respiratory organs with a respirator.

Fiberglass is often called a type of fiberglass. However, such statements are erroneous. The materials differ in production technology: glass fiber wallpaper is made of fiberglass by weaving, and fiberglass - from fiberglass threads by pressing. This difference determines and different areas material applications: glass wallpaper is used for the topcoat, while canvas is used to prepare the surface for further finishing.

Views

Painting glass canvas may have different density... Based on this, there are 3 groups of "cobwebs":

Density 25 g / m2

The material is ideal for gluing to the ceiling for painting, therefore it is also called ceiling. The light weight of the canvas does not put stress on the surface and absorbs less paint. It can be used on a relatively flat ceiling with small cracks.

Density 40 g / m2

A multipurpose fiberglass, which is recommended for surfaces more damaged by cracks than the ceiling. Performance characteristics allow the use of fiberglass of a given density for walls, for ceilings finished with dilapidated plaster, as well as on surfaces with a high vibration load. The topcoat is also varied, plaster, paint, wallpaper, based on fiberglass or non-woven coatings.

Density 50 g / m2 or more

Technical features allow the material to be used in industrial premises, garages, as well as on surfaces subject to large destruction with deep cracks. This type of "cobweb" is the most durable, and its use is more costly. The costs are associated with the purchase of the material itself (the higher the density, the more expensive), as well as with the increased consumption of glue.

Manufacturers

Today on construction market You can find glass wallpaper of various brands. We offer you a selection of manufacturers who have won the trust of buyers.

Vitrulan

German company takes a leading place in the production of fiberglass. Vitrulan is engaged in the production of wallpaper, including water-active, the range is replete with materials and tools for painting works, as well as variations of fiberglass. The manufacturer also produces already painted canvases, fiberglass, which imitates fabric textures, has a varied relief.

Buyers note the high performance properties of the material and, importantly, the absence of fiberglass chips when cutting and installing the blade. Finally, the manufacturer produces material with a wide variation in density - from 25 to 300 g / m2,

The company regularly updates its assortment offering innovative solutions. So, those who do not want to bother with glue can purchase glass cloth from the Agua Plus collection. It already contains an adhesive composition. It can be "activated" by wetting plain water... After that, the glue appears on the surface of the "spider web", it is ready for gluing.

Wellton and Oscar

The products are manufactured by the Alaxar production group, which unites leading companies from Germany, Finland, and Sweden. The main activity is the production of wall and ceiling coverings. In addition, related products and tools are produced.

The brand boasts a wide range of premium materials and more available options... Of the features - a wide selection of material in terms of density (from 40 to 200 g / m2), the ability to purchase material by meter, as well as its high performance properties, including the possibility of multiple staining.

Together with fiberglass, you can pick up glue for fixing it from the same manufacturers, which is very convenient.

The cost of the material is lower (about 1,500 rubles per roll), but it tends to crumble, and therefore requires overalls for installation. There are minor defects on the surface of the fiberglass.

Of the domestic manufacturers, the products of the companies "Technonikol", "Germoplast", "Isoflex" deserve attention. The first manufacturer offers increased strength fiberglass, which is successfully used for decoration industrial premises, roofing insulation, as well as heavily damaged surfaces. The advantage of the majority of domestic glass fibers is their affordability.

Russian manufacturer X-Glass is one of those who manufacture glass non-woven fabric in accordance with European requirements. It is distinguished by its versatility of use, perfectly reinforces surfaces, hiding small and medium cracks and preventing the appearance of new defects. The collection of the brand is not as diverse as compared to European competitors, but X-Glass products are notable for their affordability. In other words, it is great option for low-cost repairs without concessions to the quality of the coating.

Reviews

According to independent consumer ratings, the leading positions are occupied by glass fabrics of the Oscar brand, slightly inferior to them are the products of the Wellton company. Many users note that the cost of the roll is above average, but the higher price is compensated for by the impeccable quality of the material and the ease of its application.

Wellton fiberglass is actively recommended for stickers on ceilings and plasterboard surfaces., noting the ease of application, good adhesion rates, the ability to carry out subsequent finishing work on the next day. Among the disadvantages is the appearance of stabbing fiberglass particles during installation.

Those who are professionally engaged in apartment renovation strongly recommend using Wellton, especially in new buildings. It is important to carefully protect your hands and face from glass dust; ideally, wear protective clothing.

It is better to refuse to buy cheap Chinese and domestic glass fibers. The material spreads out under the action of glue, requires considerable effort to fix, and when further painting at the joints, it sometimes clings to the roller and lags behind the wall.

Preparatory work

Gluing fiberglass is a simple process that you can do yourself. Before starting work, make sure that your hands are protected with gloves and your respiratory organs with a respirator. This is because fiberglass can form particles when cut. They can cause burns if they come into contact with the skin.

The use of the material begins with its cutting. The size of the piece of material you need is one that is comfortable to work with. As a rule, fiberglass is glued to the wall immediately from ceiling to floor. However, you can divide it into 2 parts and glue them one on top of the other. To fix the "spider web" on the ceiling, professionals recommend cutting a canvas no more than 1-1.5 m long.

Determine the front of the material before sticking it on. When the roll is unrolled, it will be inside. The outer side (to which the glue is applied) is rougher.

Also, at the stage of preparatory work, the glue should be diluted according to the instructions. Adhesives designed specifically for fiberglass should be used. Each type of canvas has its own glue. Adhesive for non-woven wallpaper is also suitable, it will hold glass fleece of any density.

Usage

Fiberglass is used when performing many types of construction and finishing works:

• wall reinforcement for a better finish;
• preventing the formation of cracks in the topcoat and masking existing cracks;
• preparation of walls for application decorative coating- when using fiberglass, you do not need to putty the surfaces with finishing putty;
• alignment of walls;

• creation of original effects on the surface of the topcoat (for example, marble effect);
• use at roofing works ah as a basis for bituminous mastic(apply special types materials that improve the adhesion of the roof and mastic);
• pipeline protection;
• waterproofing works - fiberglass is used to strengthen and protect polyethylene sheets;
• organization of drainage systems.

The material is suitable for application on any surface - concrete, plasterboard, and can even be glued on top of the layer old paint(it is better to scratch furrows on it to improve traction).

The use of the "cobweb" is recommended especially for those surfaces that are exposed to constant mechanical stress. Wallpaper, paint and other materials, fixed on top of glass fiber, will last you longer without changing the original attractive appearance, even if the structure shrinks.

The glued web of "cobweb" allows you to abandon many operations. You do not need to prime the surfaces, you also do not need finishing puttying (if you do not plan to glue the wallpaper). If the walls are relatively flat, without potholes, then it is enough to fix the fiberglass.

The glued fiberglass dries quickly, and the application of subsequent finishing will be faster. This will save you time and effort on repairs.

It is ideal for application under ceiling covering as it will provide a flawless finish. The fiberglass mat glued to the outer corners will help to quickly and beautifully glue the wallpaper in this area.

When applying the glue to the fiberglass, it is best to apply it slightly wider than the material's width, as it absorbs the glue quickly. When gluing the canvas to the wall, iron it well with a clean rag, and when it "grabs" a little - run it with a spatula. This will help eliminate air bubbles from the space between the web and the base. After the fiberglass is securely attached to the wall, apply glue to the front side so that it darkens with the glue.

Fiberglass has found its application in the construction and renovation of buildings, as a material that strengthens the enclosing surfaces, used to insulate structures. At its core, it is a reinforcing element, replacing steel reinforcement.

Fiberglass - what is this material

Reinforcing material - fiberglass, used in the decoration of ceilings and walls, is produced in the form of non-woven fiberglass sheets. It is often called a "spider web" because of minimum thickness fibers and often combine the concept of fiberglass and fiberglass wallpaper. Although it is completely two various materials according to its characteristics, production method and field of application. If fiberglass wallpaper is made on weaving equipment, then the "spider line" is made by pressing. But these two materials have common characteristics:

• they perfectly tolerate exposure to a humid environment;
• antiallergenic;
• are made from environmentally friendly raw materials;
• are not afraid of high temperatures;
• not electrostatic;
• hygroscopic and breathable;
• not susceptible to mold and various pathogenic fungi;
• can be colored repeatedly.

Fiberglass is produced in various thicknesses, which determines its density. The minimum density is 20 grams per one square meter, maximum 50 grams. A material with a lower thickness is used when finishing surfaces with coloring compositions, a denser fiberglass is used when surfaces require leveling and strengthening. On sale fiberglass is presented in rolls of a meter wide, 20 or 50 meters long.

What is fiberglass for?

Primarily non-woven fiberglass material is used to reinforce bearing capacity enclosing surfaces (walls, ceiling), when there are already significant cracks or to prevent their appearance. The use of fiberglass in homes is especially important. new building when shrinkage processes constantly affect the building envelope.

It is also good to use reinforcing material in old buildings, when the plaster on the walls and ceilings is already weak. When leveling walls with plasterboard or installing suspended multi-tiered ceiling structures the use of the "cobweb" would be more than appropriate. Adhering the fiberglass will help to avoid frequent repairs and ensure that there are no cracks on surfaces treated with this method. Moreover, the surfaces can be:

• brick;
• concrete;
• wooden;
• plastic;
• metal.

Considering that the material made from fiberglass is not afraid of exposure to water, it can be used to decorate walls and ceilings in rooms such as bathrooms, saunas and swimming pools, if the finish is painting. Fiberglass under the wallpaper is not glued.

Walls trimmed with fiberglass, claws of pets, mechanical impact in the form of blows, accidental contact with chemically active substances will not be scary either.

In addition to using fiberglass on walls and ceilings, it can be used as one of the layers of noise or waterproofing "pie" when installing floors and mastic roofs.

How to glue fiberglass on walls

First of all, you need to determine the front and back of the material. Typically, the outside on a roll is the wrong side. If you feel the material, then on the one hand it is smoother, on the other, fleecy. Seamy side with a fleecy texture, respectively, face surface has a smooth texture. Sticking should be done with the wrong side to the surfaces for better adhesion. But, even if they are confused, nothing terrible will happen if the sticker process itself is done correctly and efficiently.

Only the surface of the walls is treated with glue; it is not required to coat the fiberglass material with glue. The walls are preliminarily cleaned of dust, dirt and primed either special formulations or adhesive solution poor concentration. Deep cracks and depressions are repaired with plaster and primed again. After the primer has dried, you can start gluing the "cobweb".

It is necessary to use protective equipment- with gloves, a respirator and protect the skin of the body with work clothes. The smallest fiberglass particles irritate the skin and respiratory organs.

How to glue fiberglass for painting

The material is cut into strips corresponding to the height of the walls with the addition of 10-15 cm along the length, so that it is possible to combine the pattern of fibers at the joints. Cobweb fabrics are glued only “end-to-end”. It is allowed to overlap the material at the joints if it is required to paste over curved surfaces or structures that are complex in shape, as well as if the material in the roll already has damaged edges. As well as regular wallpaper, the first panel is glued strictly vertically using a plumb line or building level... A piece of material is applied to the glue-coated wall and without special efforts smoothed with a roller or a special spatula.

If necessary, overlapping stickers are applied to the edges of adjacent panels to such a width that the damaged edge can be removed later. Immediately, without waiting for the glue to dry and using a clerical knife, two edges are cut. Carefully lifting the cut parts of the panels, remove the damaged edges of the upper and lower panels. The joint is primed with glue and ironed again with a spatula or roller and left until the glue is completely dry.

How to glue fiberglass to the ceiling

The preparation of the ceiling is carried out according to the same algorithm as the walls. But for pasting the ceiling surface, a "spider web" of low density is most often used, a maximum of 25g / kV. m. Material of high density may simply not hold on to the ceiling. The gluing process should be started from the window in the opposite direction. All windows and doors must be closed to prevent drafts.

The adhesive is applied with a brush or roller to the ceiling surface, after which pieces of fiberglass are applied to the ceiling and smoothed with a dry clean roller or wallpaper spatula. The glued "cobweb" is painted in two layers, taking a break from work to dry each layer. With this method of the sticker, the texture of the fiberglass, the pattern of the fibers will be visible.

If you want to make the ceiling as smooth and shiny as possible, a layer of putty is applied over the glued material. After drying, it is carefully sanded with the smallest sandpaper so as not to touch the fibers of the "cobweb".

To make the joints of the fiberglass material invisible, the panels are glued in two ways:

1. The first is with a couple of millimeters gap at the junction. This gap is then carefully putty and sanded. Once the paint has been applied, the joint will be virtually invisible when viewed directly. If the eye falls on the joint from the side, then dark stripes are visible on the width of the applied putty layer. This is explained by the fact that when sanding the putty, not only the texture of the material is disturbed, but also the fiberglass itself, as a result of which the light from the surface treated in this way is not reflected.
2. The second method consists in gluing the fiberglass without leaving a gap, directly "in the joint" or even with an overlap. But even with this method, the junctions of two adjacent strips of material can be visible when looking at the ceiling directly.

It happens that after drying, air bubbles form on the pasted surface. In such places, the fiberglass is carefully cut out, being careful not to damage the base base, and a new piece is glued in.

What glue to glue the fiberglass

Glass-fiber material is glued with special compounds designed specifically for it. The manufacturer must indicate this in general information on the package. Experts recommend using glue "Wellton", "Oscar", "Oscar Pigment" or "KLEO Ultra". Compositions are sold both dry and ready-to-use. Suitable both for gluing a painting "spider web", and for glass cloth wallpaper.

If Cleo Ultra glue is used, it is recommended to add PVA to it in a ratio of 1 to 6. This will increase the reliability and durability of the glued fiberglass.

Glass fiber paint

When gluing the "cobweb" for the purpose of its further coloring, it is necessary to choose a coloring composition. It is recommended to use water-based formulations:

• latex paints;
• acrylic;
• silicone.

The most affordable price will be acrylic paint, which creates a matte surface, latex, with which you can make the surface glossy, is more expensive, but its quality characteristics are also higher. The most expensive is silicone-based paint, which has the property of repelling dust and dirt. It practically does not have the disadvantages inherent in the first two. The surface, painted with such a composition, is easy to damp cleaning.

How to glue fiberglass on drywall

Before sticking the "cobweb" on the plasterboard surface, it is treated with a putty, applying the composition with a thin continuous layer. If the putty is applied in separate places, then later, after painting, the surface may be heterogeneous in color.

At the same time, all joints, points of attachment of sheets with self-tapping screws, and other flaws plasterboard surface must be pre-glued with a special tape - "serpyanka" and putty flush with the main sheets. If this is not done, then all the irregularities will be clearly visible on the painted surface. In addition, self-tapping screws that are not hidden under a layer of putty, over time, under the influence of the water contained in the paint formulations, can appear on finished wall or ceiling rusty stains, which will be difficult to get rid of.

After the putty layer has dried, the surface is cleaned with fine emery paper. This is followed by the priming stage with the composition deep penetration in two layers. Moreover, the second time the primer is applied no earlier than the first layer dries.

Fiberglass is glued to the surface of the gypsum board sheets in the same way as on all other surfaces. Myself technological process is no different from similar work on the surfaces of walls or ceilings. You just need to wait until the primer layer is completely dry.

Painting fiberglass is a material consisting of special glass fiber filaments. The second name is cobweb. Certified, done by Specifications... It is produced by the principle of pressing, at the end of the work sheets are obtained, the density of which is 25 - 55 g / m2. Possess properties:

• Waterproof;
• Are not afraid of fire;
• Resistant to chemicals;
• Capable of reinforcing walls;
• Do not attract dust;
• At the heart of natural substances;
• Allow air to pass through;
• Vapor permeable;
• Able to prevent the formation of fungal infections, mold;
• Safe for health, anti-allergenic.

In some qualities they are similar to paper or fiberglass. Fiberglass holtex lacks a crisp top and interlaced pattern. The surface can be painted an unlimited number of times.

Why do we need a fiberglass cobweb if the walls will be painted? In order not to prime, putty, level it is enough, stick the "cobweb". Concrete, chipboard, gypsum board, metal or plastic can be pasted over. The "gossamer" hides gaps, cracks, irregularities on the surface, preventing the appearance of new imperfections. Provides additional protection to walls before painting. Best suited for ceilings.

Advice: if there is a need to putty the fiberglass, the best tool will be a wide spatula for the final work.

There are several types of fiberglass. The most durable is the cobweb. The density of the first economy option is 1 * 20 g per sq. M. The density of the second option contains 40 grams per square meter. Heavy in weight, but cheaper. The third type is the most durable - 1 * 50 g per sq. M. Able to hide the volumetric imperfections of the walls. It is used on large perimeters. In terms of pricing policy, it is expensive.

Advantages and disadvantages of fiberglass gossamer

Like any material, x-glass "spider web" has its own characteristics, positive and negative qualities.

Technical characteristics and field of application of the material

If you use a glass canvas painting, you will get an environmentally friendly room. Fiberglass spider web for painting is produced by many manufacturers, which one to choose? Wellton (W30, W40, W50), Semtex, Holtex, glass, Weltex, Polinet are the best on the market.

The price for one roll is 500 - 800 rubles. The volume is 25 m2 or 50 m2. Universal width 1 m.

Painting fiberglass cobweb has application in repair work walls, ceilings. Fiberglass, velton, properly glued to plastered or plasterboard walls. Replaces finishing putty. Glued special glue, primed, putty, dries, then painted with a roller.

If you avoid putty, then you need to prime with a liquid solution, paint. In this case, you need a lot of paint. What for? Because you need to paint 3-4 times. How to paint a fiberglass spider web is presented in the video:

How to properly glue a glass canvas painting with photos and videos

Is it possible to glue the wallpaper on a spider web on fiberglass - this phrase is often heard by consultants of building stores. There is a special technology for working with the material. Before gluing, preparatory work is carried out. If the walls have minor flaws, nothing should be repaired. In case of naivety of large cracks, treat with a putty. After drying, go through the plaster. The result is a smooth surface treated with a primer solution.

Now let's start gluing. Apply glue liberally to a dry wall or ceiling. It is recommended to apply approximately the size of one sheet. Thanks to the good fit, there will be no excess glue under the fiberglass. For the convenience of work, cut the sheets in advance. It is important not to confuse the front side. Gradually applying the side of the canvas to the wall, you need to smooth it out with your hands or with a construction triangle. Remove air, excess glue after gluing in the same way. Then remove the excess length, saturate the sheet with glue on top. Smooth out after a while finished surface spatula again. Another sheet is glued with an overlap. Saturate the surface adhesive composition overlapped ready-made glued sheet. For an even and inconspicuous seam, cut a strip through both layers. After the joint, grease well with glue. The result is a smooth seam without sticky tapes. In the corners, Oscar's fiberglass is cut. It will take a day to dry. Then he starts finishing. If the wall will be painted, putty the surface 2 times. For gluing wallpaper - 1 time.

Glue consumption per 1m2

Glue for fiberglass, a cobweb will need a special one, such as for fiberglass. It is not often that manufacturers sell it in a set of fiberglass. For quality work, you must use the instructions correctly to avoid a liquid consistency. You need to buy glue with a margin, because you need a lot of consumption. Oskar-profi glass canvas painting does not like through air when drying. It is recommended to close doors and windows during work. On average, 200 ml is used for 1 liter of water. glue.

Ready-made glue based on PVA, starch is on sale. On average, a 15 kg bucket of glue is used for 25 m2. Accordingly, 0.4 kg of glue will be used for 1 m2. You can determine exactly how much glue you need using the description on the package.

• Liquid glue retains its qualities for 10 days after opening.
• To prepare a dry mixture, it will take 15 minutes to swell.
• High-quality glue does not stain, does not stain, odorless.
• Colorless when dry.
• Contains antifungal components.
• The composition contains chalk for flexible application.
• Dries completely in 2 days.

These are the characteristics of the trademarks: Kleo, Metylan, Quelyd, Pufas. Sold in liquid and dry form. Dry packaging in 250 and 500 grams. Liquid glue is produced in 5 kg, 10 kg, 15 kg.

Tip: It is not recommended to save and add more water, otherwise the material will not be strong and will begin to flake off.

Photo gallery of finished works

Many people consider renovation to be an occupation that will certainly take a lot of time and effort. And that is why it is so important for them that, in the end, everything is done perfectly and remains so as long as possible. Here, it is in order for such desires to become a reality that a glass canvas was created, which is also called a "cobweb".

What is fiberglass

Probably, many have never even heard of this. building material, like fiberglass and therefore it is important to first find out what it is and what it is made of. So, this material made of quartz or silicate sand, or rather, glass. “It's fragile,” you probably think. The fact is that the cobweb is made of the finest glass threads, and as a result of pressing them, an incredibly strong, very flexible and thin fabric is obtained.
This type of material is used to reinforce the surfaces of walls, ceilings, etc. It prevents the appearance of cracks on the surface, evens it out, and also fixes the putty or plaster. Fiberglass can be painted, primed, wallpaper glued to it, etc. It guarantees the preservation of the integrity of the finish.

What are the advantages?

This type of material, like fiberglass "cobweb" is gaining more and more popularity among people every day. construction profession... But what contributes to this? What are the advantages of this material? So, here are just a few of them:

1. Resistant to moisture, so it can be used even in rooms with high humidity, such as a bathroom, kitchen, and so on.
2. It differs in that it does not attract dust at all.
3. It allows air to pass through with ease.
4. Prevents mold and mildew from spreading.
5. It is safe for humans and environmentally friendly.
6. Resistant to fire.
7. It is very easy to clean from dirt with a damp, clean sponge or cloth.
8. Also resistant to corrosion.
9. Does not contain substances that can cause an allergic reaction in a person.
10. Does not accumulate static electricity.

This material is not only very strong, reliable and inexpensive, but it is also quite easy to work with. If everything is done according to the rules, then after completing the repair, you will admire your transformed home for more than one year.

Cons of fiberglass and precautions

Any finishing material has both positive sides and negative. However, before deciding whether it is right for you for the job or not, you should weigh the pros and cons.
So, the main drawback is the smallest particles of fiberglass, which inevitably form during work. So, for example, when cutting material and gluing it. On contact with the skin, they can cause irritation. To avoid this, it is necessary to wear thick gloves and overalls for work.
Experts also advise, in no case to start working with fiberglass, if your eyes, nose and mouth are not protected. To do this, you can use a bandage or a respirator and goggles. If you dress correctly, then in the process of work you will receive absolutely no harm to your health.

Almost every surface, be it a ceiling or a wall, needs finishing... In order to make this process much easier, fiberglass is glued. When using it, the need to use a starting putty is completely eliminated.
Experts recommend using this type of finishing material without fail for those surfaces that are very often exposed to mechanical damage or there is a threat of cracks. Fiberglass is able to strengthen these surfaces, and this is possible due to the fact that it is incredibly strong and durable.
Most of all given view material is suitable for finishing the ceiling surface. It is very important to consider here that it can be glued to almost any wall or ceiling. For example, this reinforcing material can be used to strengthen surfaces such as: concrete, plastered, made of drywall, and so on. As a result, you get a very flat surface that can be finished at your discretion, for example, paint, putty, glue wallpaper, and so on.

Advantages of fiberglass in various fields of application

However, this type of material can be used not only to strengthen the surfaces of the walls and ceiling. It can be applied in other areas as well:

1. Fiberglass is used during roofing works. So, there are such types that are used as a basis for bituminous mastic.
2. With this material, you can protect the pipeline.
3. To strengthen the walls. In this case, a glass fiber painting is used. It creates a reliable protective layer that will protect the surface from cracks, both small and large enough. And he is able to prevent even cracking of the walls, the cause of which is the shrinkage of the structure.
4. It is also used during the manufacture of a waterproofing layer. This material is often used for processing polymer webs.
5. Very often this material is used in the manufacture of drainage systems.
6. Also, fiberglass is used by designers, creating real masterpieces from this material.

Also, this reinforcing material is used in order to save money. And at the same time it is possible to save quite a decent amount. The point is that the use of fiberglass helps to significantly increase the time between repairs.

Preparatory stage before pasting the surface with a "cobweb"

It is quite easy to glue such finishing material as fiberglass "cobweb" to the desired surface. And almost everyone can handle this. To do this, it will be enough to observe a few very simple rules, and then the result of your efforts will delight you for more than one year.
You decide for yourself what width or length to cut a strip of fiberglass. For example, to glue the surface of a wall, you can use strips equal to its height. However, when finishing the ceiling, experts recommend using strips no more than 1.5–2 m in length.
It is also very important, before sticking the "cobweb", to check where its front side is. The thing is that the seamy side and the front side are very similar to each other. However, this material must be glued correctly. How to distinguish the sides? You can find this information on the packaging or in the instructions attached to the fiberglass.
Then you should apply a special adhesive to the prepared and always dry surface of the wall or ceiling. The applied layer should be slightly larger than the width of the finishing material. The thing is that the glue is absorbed and dries pretty quickly.

The gluing process

After the finishing material and the surface to be pasted have been prepared, you can proceed to the direct finishing process. You just need to place a strip of fiberglass against the wall and smooth it out with a rag or with your hands. Finally, iron the surface with a spatula, taking care to remove all air from under the glued material.
After you make sure that the strip is firmly adhered, you will need to remove all excess with a sharp knife. And only after that you can start applying the adhesive directly to the front side of the material. It should be completely saturated with glue, so that its color over the entire surface becomes dark with moisture.
Then you can proceed to gluing the next strip, while taking into account that they are glued with an overlap. It is better, if possible, to make the strips the same size. And the professionals advise to glue the ceiling exclusively along the room.
After the second sheet is also smeared with glue, you need, armed with a very sharp knife, cut in the place where the overlap is made straight line... And then you will need to remove all unnecessary in such a way that you end up with a perfectly flat surface.

How to paint correctly

After the fiberglass dries, you can start finishing the surface. And most often this finishing material is painted. However, in contrast to sticking the "spider web" itself, coloring it is a rather difficult task that can take a lot of time and effort. And all this because this material has a porous structure and therefore the paint will be absorbed into it very quickly, and at least it will be necessary to apply at least a couple of layers of the dye.
For coloring, it is best to choose a water-based paint. The fact is that it is applied much easier and smoother. And also if you apply several layers, the surface will still remain perfectly smooth.
It is also better to prefer paint roller brushes. You just dip it in paint and paint the surface. However, there are two things to keep in mind here. First, the joints must be painted over very carefully, using a special "wing". And the second - the interval between the application of layers should be at least 12 hours.
Also, do not forget about the precautions. When dyeing the glass fiber painting, do not forget to wear special clothing that will protect you from small fiberglass that gets on open area skin can cause quite unpleasant sensations. And it's not so easy to get rid of them.

Is it possible to paste over the fiberglass with wallpaper?

Some people don't like painted walls and opt for wallpaper. However, many people ask the question: "Is it possible to stick wallpaper on a fiberglass?"
You can glue the wallpaper, but only before that, the fiberglass must be putty. And only after the putty is completely dry, you can start finishing the surface with wallpaper.
It should be noted that the putty surface can also be painted. In this case, you can reduce the consumption of paint several times. And another advantage of painting such a surface is that it will turn out to be very smooth. After all, if you apply the paint directly to the fiberglass, then a kind of relief of the finishing material will appear through it.

The nuances of pasting drywall with fiberglass spiderweb

It is very common that the surface of the ceiling or walls is finished with plasterboard. In order to strengthen and prevent deformation of the surface, fiberglass is also used. However, there are a couple of important nuances in pasting such a surface with this type of finishing material.

1. First of all, you will need to putty to coat all the joints and entry points of the screws. As a result, you should have an almost perfectly flat surface. Be sure to wait until the putty is completely dry.
2. Then you will need to coat the entire surface of the drywall with glue - this is a primer layer. And it will be possible to start finishing the surface with a "cobweb" only after the glue is completely dry. By the way, an adhesive must be used that is specially designed for this kind of finishing material. Further, pasting is carried out according to the above scheme.

Before proceeding with the direct finishing work, you need to find out a few professional tips:

1. Typically, a lower density material is used for ceiling decoration, and a higher density for walls. It is very important to take this into account when choosing fiberglass, since in otherwise the finishing process can be quite complicated.
2. It is also important to choose the correct and very quality glue... You shouldn't economize here. Choosing a poor-quality or unsuitable adhesive can negatively affect the final result and significantly reduce the time between repairs.
3. When gluing a ceiling surface, it is very important to use a reliable ladder. It should be noted that the ladder is not suitable in this case, since both your hands must be absolutely free.
4. Working with fiberglass must be very careful. You should avoid deformation of this finishing material, as this will have a very negative effect on the final result.

Painting fiberglass cobweb is becoming more and more popular every year. And if during the finishing work you do not make mistakes, then the result of your work will delight you and your guests for many years. And to change the design, you just need to repaint the walls or ceiling in a different color, or paste new beautiful wallpapers.
