The use of cobwebs in finishing works. What is fiberglass “gossamer”, what qualities does it have, and what is it needed for?

The use of a building material called fiberglass is one of the best options for high-quality and durable finishing of the internal surface of walls and ceilings. With its help, you can avoid the appearance of cracks, and the sticker process is quite simple and quick. At the same time, painting fiberglass sometimes causes controversy among repairmen. Some experts believe that there is no need to putty the surface before doing this, while others are convinced that it is necessary to level the canvas before applying paint.

Material advantages

The strength of the “web” is relatively small; careless handling can lead to its damage. However, the answer to the question of whether fiberglass is needed for painting is most often positive - due to the many advantages of using this material:

After proper sticking to the surface, the “web” from a weak and fragile sheet turns into a reinforcing mesh that hides small imperfections in the wall or ceiling and prevents new cracks and defects from appearing.
The material is practically resistant to exposure to liquids, fire, aggressive substances and abrasion.
Fiberglass is not an allergen and does not accumulate static.
“Gossamer” is easy to clean and allows water vapor to pass through during operation, providing optimal humidity in the room. And it is also quite environmentally friendly material, which does not emit substances harmful to humans into the air.

In fact, the material has all the advantages of glass wallpaper. Although it is not intended for final finishing, but only for surface reinforcement. At the same time, canvas can be painted several times, unlike wallpaper.

Fiberglass sticker

Before deciding whether it is possible to paint fiberglass and putty it before or not, the material needs to be glued to the wall. In this case, the surface to be glued needs to be prepared - leveled using putty, leaving no more than 1 mm thick. You can refuse leveling only in cases where the wall is already quite smooth and strong.

The main nuances that arise when carrying out preparatory work:

wide cracks are sealed using a special compound for seams or regular putty, but in several steps;
using plasterboard sheets the joints between them must be puttied and reinforced with self-adhesive fiberglass mesh (“serpyanka”); In order for the already pasted wall to be as smooth as possible, it is desirable that the seams between the drywall and the fiberglass sheets do not coincide with each other, otherwise cracks may appear in these places;
dried “patches” on the wall need to be leveled using putty and sanded until the surface is almost perfectly flat;
Before the fiberglass web for painting is glued to the wall, it should be cleaned of dust and thoroughly primed.

Due to the fact that the fiberglass sticker is overlapped, when determining its area, you should take it as calculated value not only the surface of the walls, but also a small margin (at the level of 5–10%). And as an adhesive, it is advisable to use not ready-made, but dry glue, the characteristics of which are the same, and the price is much lower. During the work, special clothing is used - pants, long-sleeved shirts, gloves, a respirator and a hat. All this will help prevent fiberglass particles from getting on the skin and into the respiratory tract.

Other nuances that are taken into account when labeling include correct styling canvases. Fiberglass sheets have a smoother front side– as a rule, it is located outside the roll. It is she who should look inside the room, while the outside one should be applied to the wall or ceiling. You should also place the canvases so that the pile on them is directed in one direction. Otherwise, the paint applied to the material will have different shades.

The main stages of gluing fiberglass for painting are as follows:

The roll is rolled out and cut into sheets of the required size, which is selected for the walls taking into account a slight overlap. For the ceiling, it is recommended to choose canvases up to 1.5 m long, which are easier to attach to a vertical surface.
Glue (prepared according to instructions or ready-made) is applied in a thick layer to the surface, starting from the corner of the room. The width of the strip should be slightly larger than the size of the fiberglass itself, that is, about 1 m.
The first sheet of canvas is glued close to the corner of the room, pressed with your hands and smoothed using a wallpaper spatula along the entire length from the middle of the canvas to the edges.
The excess part of the fiberglass is trimmed with a knife along a ruler.
The canvas, already glued to the surface, is coated with glue until the material is completely saturated. You can determine that the canvas has been completely coated by its color, which should become uniform by the end of the procedure.

The remaining sheets are laid in the same way, but with a slight overlap on the previous ones. After gluing and alignment, both panels are trimmed along the joint using a ruler. The cut parts are removed, and the resulting smooth seam is once again smeared with glue and pressed with a wallpaper spatula. When gluing corners, they try to get an even joint before cutting - the corner cloth tears more often than others, and a perfect cut will help avoid tears and cracks.

After the room has been completely covered with fiberglass, it is left closed until the glue dries completely. Usually this period lasts at least a day. At this time, drafts should not be allowed to appear in the room, otherwise air movement will lead to the material falling behind and the need for gluing it or even re-gluing it.

The procedure for gluing fiberglass

Do I need to putty before painting?

One of the main advantages of using fiberglass is the ability to almost immediately stick wallpaper or apply paint on it. This raises the question: is it possible to paint fiberglass without putty or is it still needed? In the first case, you can save time on drying the material leveling the walls, in the second, the quality of the finish improves.

Even professional builders disagree on whether it is necessary to putty fiberglass before painting, but most of them advocate the use of putty for the following reasons:

Due to its high absorbency, the material will have to be painted in several layers - usually from 2 to 5 times. In this case, a huge amount of paint will be consumed and much more time will be spent than would be saved by not using putty.
The texture of fiberglass is noticeable even under 1-2 layers of paint. As a result, painting fiberglass without putty can ruin the interior of the room. The pores of the material are very difficult to paint over and appear again after applying the next layer of paint. And only putty will help eliminate this drawback.
When painting fiberglass, especially those located on the ceiling, a lot of small fibers fall on the person doing the work. And, rising into the air, they can end up inside the respiratory organs. Painting a putty surface is not only easier, but also safer.
If after renovation it was decided to replace the paint on the walls with wallpaper, it is almost impossible to do this on an unputtyed surface.

Considering these disadvantages, it can be noted that it is undesirable to paint fiberglass without putty - except in cases where the surface is smooth and smooth surface in a room (for example, a household or utility room) is not very necessary. However, using this material, even taking into account additional work, is still more profitable and convenient than immediately puttingtying ceilings and walls, skipping the stage of working with canvas. In the future, surfaces protected by it will last longer, and the likelihood of cracks appearing is almost zero.

Painting the surface after puttying

The main reason that painting of fiberglass web is carried out only after puttying work is carried out is the need to smooth out irregularities - fibers and joints between glued sheets. Unfilled joints become especially noticeable after painting. As a result of using putty, the surface will become smoother, and defects will disappear only with very careful work. Moreover, painting walls or ceilings after leveling with putty is much easier and faster.

It is important to take into account that when painting fiberglass without putty, you will need many times more paint, since strong absorption occurs, and you should not hope that the paint will mask the joints.

The main way to paint fiberglass consists of several stages:

After the canvases glued to the walls have dried, a primer is applied to them.
On top of the dried (usually it takes from 1 to 6 hours) primer layer, putty should be applied along each joint. Layer thickness – no more than 1 mm. The result is low material consumption, a fairly smooth surface, and minimal drying time (about half an hour).
When the layer of putty has dried (a finishing compound is used to finish fiberglass), the entire surface of the wall or ceiling is treated.
Having reached the required number of layers and making sure that there are no irregularities, gaps or cracks left on the putty area, use sandpaper or silicon mesh for stripping. Then they carry out the final primer and begin painting the fiberglass on the walls.

The process of painting canvas is no different from painting most other materials. To do this, use acrylic, silicone and latex paints, and rollers, sprayers and brushes as tools. To obtain the maximum quality of the coating, it is advisable to paint the fiberglass in 2-4 layers and additionally brush hard-to-reach areas.

In the process of finishing concrete ceilings Often you have to deal with cracks and irregularities. To ensure that the screed is strong and does not crack, the base of such a surface is reinforced with a painting “web”. To achieve good quality of the procedure, before carrying out it, you need to understand why it is needed. In the previous publication, the issue of working with fiberglass was deliberately not addressed. This topic was planned for consideration in a separate article, which is now offered to your attention.

Main characteristics of the material

The basis of this material is glass: during the manufacturing process it is melted, drawn into threads and twisted into fibers: these serve as the basis for producing fiberglass by weaving. Along with tensile strength, glass threads are characterized by elasticity, which protects the finished fabric from deformation. At the final stage of manufacturing, the “web” is treated with a special impregnation that increases its stability. Density finished material is in the range of 25-65 g/m2.

Fiberglass has a number of advantages:

Environmental Safety. To make the material, only natural ingredients are used that do not cause allergic reactions.
High strength and durability. Fiberglass copes well with both mechanical and temperature influences.
Does not collect dust. Electrostatic inertness makes it possible to avoid attracting light debris to the finishing surface.
Fire safety. Exceptional resistance to fire allows the use of fiberglass for finishing the corridors of large buildings through which people are evacuated in case of fire.
High reinforcing abilities. The web-trimmed base provides strength for the finishing layer.
Biological inertia. Fiberglass is not a breeding ground for microorganisms, including fungus and mold. This is facilitated by the fact that glass fibers are not afraid of water and do not rot in conditions of constant humidity.
High vapor permeability. This makes it possible to avoid “clogging” of reinforced bases.
Excellent interaction with most building materials.

Despite the great similarity, reinforcing fiberglass and are two materials with different purposes.

As for the disadvantages of the “cobweb”, the main one is some inconvenience due to small glass particles that arise when cutting the webs. It is recommended to work in protective clothing, gloves, goggles and a respirator.

Where is the “cobweb” used?

Why do you need fiberglass:

Reinforcement of walls and ceilings. It can be used to strengthen concrete, brick and other indoor foundations for various purposes. This is especially true in cases where the surface is being prepared for painting. Thanks to fiberglass reinforcement, the base is well leveled, without the threat of subsequent cracking.
Corrosion protection. The presence of anti-corrosion characteristics in glass fibers allows them to be used for protection metal pipelines for various purposes.
Manufacturing of building materials High Quality. Fiberglass is often reinforced and Wall panels. In addition, it is part of the composition, indispensable when arranging a soft roof.
Arrangement of waterproofing protection and drainage.

What is fiberglass?

The most commonly used types of webs are:

- 1. 25 g/cm2. The best fiberglass for ceilings for painting, which is facilitated by its light weight and strength. The ceiling “cobweb” has low absorbency, which allows you to save paint material.
  1. 40 g/cm2. Universal material, twice as strong as the previous version. It is used to reinforce surfaces subject to increased operational loads (rooms with high level vibration). As for strengthening ceiling surfaces with a universal “cobweb”, this is justified only if there is dilapidated plaster and cracks.
  1. 50 g/cm2. This durable material Designed to strengthen large cracks. In addition, it is often used to reinforce enclosing structures in workshops, workshops and garages to protect against mechanical damage. Increased cost of work of this type due to the high cost of the material and the increased consumption of glue for its fixation.

- 1. Wellton. This Finnish material withstands numerous repaints very well.
  2. Oskar. A less expensive Russian analogue that can be repainted several times with little material consumption. Domestic fiberglass TechnoNIKOL also has similar qualities. .
  3. Spectrum. This Dutch company offers high-quality fiberglass in various densities.
  4. Nortex. A Chinese manufacturer offering fairly high-quality “spider web”. However, its choice is limited only to the universal variety (50 g/cm2).

How to glue fiberglass to a concrete ceiling yourself

To strengthen a concrete ceiling, the so-called “ceiling web” with a density of 25 g/cm2 is usually used. Great importance have optimal conditions work, since it is recommended to use fiberglass at an air temperature of +15-25º and a humidity of no more than 60%.

Surface preparation

Before gluing fiberglass to the ceiling for painting, its surface must be completely cleaned of whitewash, wallpaper and old putty - a bare concrete slab should remain.
If base defects are detected, they must be eliminated. All protrusions are knocked down with a pick, and the depressions are sealed.
If possible, it is better to concrete surface lay a leveling layer of starting putty.

Padding

Primer. After the ceiling is completely dry, it is impregnated with a primer deep penetration. Very good in this regard acrylic compositions. Thanks to this, the ceiling surface acquires the necessary adhesion for subsequent application of the adhesive. The primer should be allowed to dry completely (usually 30-40 minutes).
Preparation of glue. For this it is recommended to use special compounds, since it will not be possible to properly glue fiberglass for painting with conventional wallpaper materials. As for PVA, it holds fiberglass well, but subsequently its surface may become coated yellow spots. It is best to use a special glue for fiberglass and glass wallpaper, which is sold in dry or finished form(usually, good brands painting canvas included assembly adhesive from the same manufacturer). A pack of dry composition is diluted in a 10-liter bucket of clean warm water: this volume is enough to glue a “cobweb” with an area of 50 m2.

Cutting and gluing

Having measured the length and width of the room, then cut required amount pieces of “cobweb”. This is not difficult to do, since the material is sold in rolls for convenience. The length of the strips is taken with some margin (about 10 cm). The same applies to the width - here you should take into account the fact that the strips are glued with a slight overlap (up to 20 mm). When cutting, be sure to wear a respirator, safety glasses and gloves to avoid getting sharp particles on the skin of your hands, eyes and respiratory organs.
The first strip is mounted from the edge of the ceiling, having previously coated this area with a generous layer of glue (the canvas absorbs a lot of it). For convenience, it is recommended to cut a line the width of the strip along the entire length of the surface. Having placed the edge of the canvas along the line, it is necessary to smooth it from the center in all directions, expelling air bubbles and excess glue. This operation is most conveniently performed with a plastic wallpaper spatula. Excessive force should not be used when pressing the tool so that the fiberglass does not tear (at this stage it is very vulnerable).

How to properly glue fiberglass strips

The next strip is glued next to the first with a slight overlap (it is immediately cut with a sharp knife, removing excess parts). For best quality It is recommended to additionally coat the joint areas with glue. As you glue the fiberglass, it is important to maintain the continuity of the process by gluing the sheets one after another.

The painting canvas has an inner and outer side - it is advisable not to confuse them. Outside usually rolled inside the roll (it is smoother to the touch).

After the entire ceiling is sealed, excess pieces of material are trimmed along its entire perimeter. Next, the entire area of the laid canvas is covered with a layer of the same glue (it is usually diluted slightly). The fiberglass for putty should dry well (1-2 days).

Features of finishing

The painting cloth creates a unique texture on the surface of the ceiling: therefore, it is advisable to putty the fiberglass “cobweb” before painting. 1-2 layers of a soft gypsum solution (Satengypsum) or ready-made (acrylic) mixture are enough. Such a ceiling should be sanded very carefully, without exposing the fiberglass. As for painting, you can use regular water-based, acrylic or latex paint, which is applied with a fabric roller in two layers.

You can skip the putty, but for high-quality painting in this case you will have to use 5-6 layers, since fiberglass has significant absorbing characteristics.

Results

Properly glued painting fiberglass guarantees excellent quality of the ceiling screed: cracks and chips will not appear on it even in conditions of strong vibration. Such a surface can be painted many times. The decision to use or not to use a “web” is influenced by the initial state of the rough foundation.

Progress does not stand still, and every time we hear about something new in the most different areas and industries. Relatively recently appeared on the market the new kind finishing coating for walls - fiberglass. This type of coating is usually called cobweb glass wallpaper because of its appearance.

Painting fiberglass web finds its application in reinforcing surfaces before finishing work. This material is not a finishing type coating, it is, so to speak, the basis for further finishing of walls and ceilings. The cobweb can be called an effective assistant in the fight against such serious problems as cracks on the surface of ceilings and walls.

Quite often, problems with cracks arise in new houses that were built relatively recently, because over time the house shrinks, painting fiberglass web, the use of which is appropriate in in this case, is the best assistant in this situation.

It should also be noted that this type finishing coatings for walls today is gaining popularity in the finishing materials market, and with quite serious momentum. The type of “preparatory wallpaper” under consideration has similarities and differences. We will also compare the manufacturing process of paper and fiberglass.

Technical characteristics and scope of material

Painting fiberglass canvas consists of fiberglass threads, like glass wallpaper, but the difference is that the web is not made on machines. The manufacturing process of the “wallpaper” in question is as follows: fiberglass comes under a press, as in the process of manufacturing sheets of paper. The result of such pressing is smooth, thin sheets, the surface of which is very smooth. The density of compressed fiberglass is 25-50 g/m2.

Although the process of making fiberglass web and paper are to some extent similar, the difference between them is colossal - unlike paper sheets, does not accumulate statistical electricity on its surface, and is also not afraid of water or damage mechanical type, nor chemical reagents. Dust is also not attracted to them and, among other things, they do not burn. It is difficult for some to imagine what such a finishing material looks like, therefore, you can watch a video showing how to use fiberglass for painting in this article.

Similar characteristics of cobwebs and paper include their composition, namely, the ingredients included in its composition are exclusively natural, as in paper, they are also a non-allergenic material, and they allow air to pass through perfectly. The difference between fiberglass and glass wallpaper is the absence of a wicker pattern and relief on the surface of the former. But here, too, there are advantages: if there are no prominent elements on the surface, then they can be painted an unlimited number of times, no relief - no problems.

How to properly glue painting fiberglass

In order to stick the material on the walls or ceiling, you do not need to have any special skills or knowledge. You just have to find out how it's done and get to work. If you don’t want to pay a lot of money to craftsmen for a fairly simple finishing process, then just follow the recommendations that will help you do everything correctly and quickly.

How to glue fiberglass webs with putty onto drywall video

To begin with, glue is applied to the surface of the ceiling or walls; you don’t need to apply a lot; it will be enough to apply glue one strip wide. The substance is absorbed quickly enough, so expel it from under finishing material- you won’t have to.
There are no standards for the width of the strips, you can cut them as you wish, the main thing is that it is convenient to work with them. With the finishing of the walls everything will be simpler, so you can cut the strip to its full length, but for the ceiling a strip of one and a half to two meters will be enough. Before gluing, check where the front and back sides are. They look very similar, but there is a difference in them, so the whole necessary information You will find this on the label.
Painting fiberglass canvas: the use of which is suitable for all surfaces in the room, and even for plasterboard structures, after fitting to the wall, it is smoothed out carefully with your hands. You need to make sure that the corner of the room coincides with the edge of the web. After that, it is necessary to run a spatula over the surface so that no air remains under the coating.

When the sheet is firmly attached to the wall, you can start cutting off all the excess that sticks out or hangs. Then apply glue to the surface again. To understand that the sheet is well soaked, it should become dark from moisture.
We glue the next sheet, the same size as the previous one, to the wall, making sure to overlap. If the material is glued to the ceiling, then it is better to glue it along the room.

Glue consumption per 1m2

The question of glue consumption when finishing walls or ceilings with fiberglass paints arises quite often, because such a process will require a lot of it. The fact is that there are no standards in this regard. It is impossible to accurately calculate the amount of glue that will be used per square meter of surface, because it will depend on who will apply this glue to the surface.

If there is little glue, you will see it yourself; if there is too much glue, it will also be difficult not to notice. In order to sufficiently saturate the surface with glue, you must monitor the color of the fiberglass web; as soon as it darkens from moisture, there is a sufficient amount of glue on its surface.

After we have glued the second sheet with an overlap, we saturate it with a layer of glue and mandatory press well against the wall. In order for the seams between the sheets to be invisible, you need to cut a strip through both glued layers, even if your cut turns out to be uneven, there is nothing wrong with that, we strive to ensure that the surface is smooth, and these unevenness of the strip you cut will not be visible on wall or ceiling.
After 24 hours, the glue on the surface will dry completely, and you can begin next stage finishing.

Painting fiberglass web application: how to paint

If you decide to paint the canvas, then we recommend using water-based paint for such a surface. Such paint will retain the properties of the finishing material itself and, moreover, more than one layer of paint can be laid on it in an even layer.

Using painting fiberglass, how to paint correctly video

For painting you will need the following tools:

a tray where the paint will be poured;
roller (you can use a paint brush, but then the painting process will take a long time).

It is necessary to paint the fiberglass spider web twice, that is, apply two layers of paint. It is worth noting that the time between applying layers should be at least 12 hours. To roll a seam, you need to use a “wing”; if you do it with a roller, the result will not be optimal. In principle, these are all the features of painting such a finishing material.

Do I need to putty on fiberglass paint before painting?

A positive quality of the web is that after gluing it to the wall, you can immediately begin painting the surface of the walls or ceiling. In this case, the word immediately means. After the surface has completely dried, simply without preliminary or preparatory work.

Fiberglass web application on the ceiling video

It is necessary to putty only if you want to have a completely flat surface of the wall or ceiling or if you want to hide the texture of the finishing material, in this case - cobwebs.

The best option for preparatory work before gluing would be to prime the fiberglass with glue, thereby reducing paint consumption. This is correct and profitable, because glue is much cheaper than paint.

Is it possible to glue wallpaper onto fiberglass webs?

To begin with, I would like to say that painting fiberglass is a material that serves to reinforce surfaces, and it is glued to secure plaster, putty, and also to avoid the appearance of cracks on the walls. This material is excellent for painting.

As for wallpaper, in the case of fiberglass, you can glue it, but before that you will have to treat the surface of the wall or ceiling, and only then start gluing the wallpaper onto the surface.

Since painting fiberglass web, the use of which is a protection against cracks, is not a finishing coating, it can be either painted or glued on top of wallpaper, but after first treating the surface.

If the gluing process seems difficult to you, and to some extent incomprehensible, then we recommend that you watch the video on our website, which describes in detail and shows how to properly glue fiberglass to a web on various surfaces.

Fiberglass reinforces walls and ceilings. Thus, in its qualities it is similar to glass wallpaper, but unlike the latter, it can be painted many times without worrying about the relief or pattern, since it does not have any.

How to glue fiberglass and what is it?

What is fiberglass? These are smooth and “spiky” translucent sheets consisting of fiberglass strands connected to each other by pressing. The texture is similar to a cobweb. The canvas comes in a roll measuring 1mx50m. Fiberglass has a number of advantages:

durable
bends easily
not afraid chemical substances, fire and water
not static
not allergic

How to glue fiberglass for painting

First of all, to know how to glue fiberglass, you need to understand why it needs to be done. Firstly, the canvas can be glued to any surface: concrete, drywall, plastic, brick, chipboard or metal. Secondly, it hides well large cracks and unevenness, and also prevents the formation of new ones. The web perfectly withstands the loads during the shrinkage of the building, thus protecting the walls and ceiling from falling plaster and tearing the wallpaper. This perfect material for leveling room surfaces. Using fiberglass, the effect of smoothness and evenness is achieved. Before you start working with the canvas, you need to prepare the surface.

To do this, it is cleaned of dust and large cracks are filled with putty. You can identify small or large cracks using a spatula. If the crack is wider than the blade of a putty knife, then it needs to be filled with putty. But if the blade does not fit into the crack, then there is no need to putty it. Then the walls are primed. This is done with a glue solution or a deep-soluble primer.

Next, the process of gluing the canvas begins. Since glue is not applied to the canvas, but rather covers the surface of walls or ceilings, the procedure for gluing fiberglass is much simpler than gluing wallpaper. The work uses glue for glass wallpaper, which is usually sold complete with cobwebs. The sheets are glued end to end. The seams are smoothed with a spatula. It is possible, and even experts advise, to glue the canvases overlapping. They are glued in the same way when the surfaces of the rooms are curved or broken. And also if the edges of the roll are tousled or damaged.

How to properly glue fiberglass

What can fiberglass be glued to? Allowed - on any type of surface with interior finishings premises. The first stage is applying glue to the surface. Next, fiberglass is glued. To ensure that the canvas is tightly attached to the wall, smooth it slightly with a roller from the middle to the edges over the entire surface. Thus, excess glue and air are expelled from under the sheet. The top is covered with a layer of glue. Using a spatula, rub the glue well into the fiberglass, since the canvas must be completely saturated. This can be determined by the color of the canvas. When the canvas is well saturated with glue, it is darker. The edges of the sheet are not smoothed much. Glue is applied to the next part of the wall.

When applying glue, we go a little onto the already glued sheet. Applied to this part of the surface new piece canvas and glued to the wall overlapping the first part. The area where two sheets overlap is easily smoothed with a spatula. Next, the overlap of two sheets of fiberglass is cut with a knife. It can be clerical.

Get rid of excess cut strips of the first and second sheets, from above and from under the canvas. It is smoothed well with a spatula, with light pressure, at the junction of the canvases. The result is an invisible seam. The seam area and the entire fabric are covered with a layer of glue. And so, step by step, we cover the entire planned area of the wall or ceiling. It is necessary to give the surface time to dry thoroughly. Next, you can paint. However, experienced painters do not recommend doing this immediately after the glue has dried. Because fiberglass absorbs paint well and its consumption will be very high. Moreover, the texture of the canvas will be visible from under the paint, even if you apply it in several layers. Accordingly, the appearance will not be aesthetic.

By using fiberglass to decorate the room and following the technology, you will forever forget about cracks and deformations of the surfaces of walls and ceilings.

Fiberglass how to glue video

Painting fiberglass, called “cobweb” because of its external similarity to a spider’s web, is widely used as a finishing and at the same time reinforcing material when performing interior work.

The use of fiberglass-based canvas eliminates the formation of cracks when the plaster dries and the building shrinks, and simplifies the preparation of plasterboard walls for painting.

The result is higher quality finishing walls and ceiling.

Choosing glue for painting web

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

OSCAR - universal dispersion adhesive for acrylic base. Designed for gluing fiberglass painting canvas and glass wallpaper for painting on various surfaces (concrete, brick, plasterboard, OSB, etc.).

Oscar glue for fiberglass web is available in the form ready solution, and also in the form of dry powder.

The adhesive contains an antiseptic additive that prevents the formation of mold in rooms with high humidity. The glue is applied directly to the surface to be glued, which facilitates the work process; the high elasticity of the composition allows you to adjust the position of the canvas.

BOSTIK 70 - modern glue based on aqueous dispersion (PVA) and starch. Designed specifically for gluing cobwebs, glass wallpaper and fiberglass.

Suitable only for dry rooms. Works great on both absorbent (plasterboard, chipboard, concrete, brick and plaster walls) and painted surfaces. Bostik glue for spider webs 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. Available in dry and ready-to-use form, suitable for all types of glass wallpaper (fiberglass).

When Nortex dries, it becomes colorless and does not leave stains. The sticker of the thick “cobweb” is done immediately after applying the adhesive to the wall.

Step-by-step instructions - how to glue cobwebs to the ceiling and walls

Painting fiberglass is an affordable and most effective material for combating cracks on walls and ceilings.

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

To complete the work you will need 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” is no different in complexity from the process of gluing ordinary wallpaper without adjustment and takes place in several stages:

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

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

A web of “cobwebs” is applied to a wall/ceiling evenly covered with glue and spread evenly so that there are no folds or 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 the second strip of fiberglass is glued end-to-end with the previous one in a similar manner.

Which side should you glue the web on? Indeed, fiberglass has two sides, the back and the front. You need to glue with 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 web is glued in a different way - overlapping with subsequent cutting construction knife two canvases.

To achieve an ideal joint, cut both layers in the center of the resulting overlap. sharp knife and carefully remove the cut strips of both canvases.

Answers to frequently asked questions

On what surface can the “cobweb” be glued?

On almost any surface - concrete, wood, drywall, plastic, cleaned brickwork and so on. The most important thing is to prepare the walls and ceiling - fill large holes and cracks, remove all protruding irregularities and prime them.

What is the consumption of glue for fiberglass web?

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

Is it possible to glue wallpaper onto spider webs?

Fiberglass is not finishing coat, it is used to reinforce the surface of walls and ceilings before finishing work. Gluing wallpaper onto fiberglass is impractical for several reasons.

Firstly, the surface of such a wall has textured surface. To hang wallpaper, you will have to re-plaster the walls, which will increase the cost repair work. The optimal solution The walls lined with fiberglass will be painted.

What is the best way to paint painting fiberglass?

It all depends on the operating conditions of the room, on what influences the surface will be exposed to. A practical solution will become latex paint water based.
