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 of chemicals, 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 perfectly hides small cracks and irregularities, 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 web has proven itself as a finishing material and has helped get rid of many problems. Today, even in new apartment There are many problems with repairs. Cracks appear on the walls or ceiling, which are very difficult to get rid of. Even if you plaster them repeatedly, they will appear again. The web mesh is designed to change the situation. The popularity of this material is growing more and more. Its use avoids possible problems further. And it is very easy to glue it. The main thing is to do everything right.
Fiberglass, one of the varieties of materials for puttying or painting. It is a thin non-woven sheet that is pressed from fiberglass threads. It looks like a grid. This material is being manufactured roll method, one meter wide and twenty and fifty meters long. It should be borne in mind that this material is not intended for finishing. Its area of application is to protect surfaces from cracks.
The web has a density from 20 g/m2 to 60 g/m2. For painting, a mesh of lower density is used, for reinforcement of a higher density. This material allows you to hide microcracks and also allows the walls to breathe. The complete naturalness of the material does not disturb the environmental conditions of the room. When used, the appearance of fungus is prevented; it does not react with chemicals. Can be used in areas with high humidity.
Fiberglass web adds increased strength to the base and prevents cracks Areas of use
This material can be glued to any surface. It gives increased strength to plaster and putty. If necessary, it can be applied before staining. Very often, cobwebs are used before wallpapering. But this can lead to the formation of bubbles, which appear due to the fact that the drying process takes a very long time.
You should know! Fiberglass has two sides - back and front. They differ in their structure, front side very smooth to the touch. The reverse side has lint, it sticks better. Although there is a correct division into sides, if they are confused, there will be no special consequences. The main thing is to comply required quantity glue and press the material tightly to the surface.
Pasting mixture
The glue for the “web” should be selected correctly. It needs a special one, which is designed specifically for this purpose. There is no need to try to save money and use other types of glue. This can lead to consequences that could not be expected.
The glue is applied thickly, but without excess. It is very convenient that if there is not enough glue, and the mesh is already glued, then you can coat it on top - saturate it. The spider web mixture has the following advantages:
- the glue is completely environmentally friendly;
- leaves no stains or marks;
- final setting time – 2 days;
- does not react to cold.
Rules for applying a web mesh
To glue cobwebs, you don’t need any special skills at all. It is important to follow the rules, which are quite simple. But if you have no experience, then it is best to practice a little. You shouldn’t take on large amounts of work right away. A little patience, and soon everything will work out like real masters.
VIDEO: how to work with fiberglass
The process of applying fiberglass can be divided into several stages. A lot depends on the correctness of their implementation.
- The surface on which this material will be glued is prepared. It is advisable to remove all irregularities, they can cause bubbles. All dirt is washed off with a damp cloth.
- The glue is applied to the wall or ceiling. You shouldn’t skimp on the glue, but you don’t need to use a lot of it either. The fact is that the process of applying a grid is very similar to wallpapering. The same rules apply here.
- A pre-prepared mesh web of the required width is applied to the surface. It is best to ensure that the front and back sides are correct.
- Fiberglass is smoothed out well. If you can’t do it with your hands, you can use a soft cloth. Using a spatula, remove the remaining air. You should move from the middle to the edge. But it's important to be careful. The web can be easily torn, which should be avoided.
- Everything that sticks out is cut off. The glue is applied again. A well-soaked sheet becomes dark.
- Subsequent sheets should be properly glued overlapping. Drafts must be avoided. Otherwise, all the work will go down the drain.
If external and internal corners are not ideal, then in these places it is best to cut the mesh. Then you can avoid the appearance of voids. Cracks in the corners must be sealed with tape (paper). This should also be done at the junctions of walls and ceilings.
Fiberglass and drywall
If the surface is made of plasterboard, it is required preliminary preparation. All seams must be sealed with putty. It is important to know that the joints of the drywall sheets and the mesh should not coincide.
Unlike simple walls or ceilings, when the web is glued overlapping, it must be glued end-to-end onto the drywall. Pruning should also be avoided. If this is not observed, cracks may form in these places.
Final stage
When complete drying occurs, and this can take up to two days, you can begin to putty the surface. If painting is intended, it is better to use finely dispersed putty. It should be applied in several layers. Each layer must be allowed to dry completely. After this, you can begin sanding using sandpaper. We must not forget that, as with simple painting, you must first prime the walls or ceiling.
Nowadays, they are increasingly skipping the puttying stage. This is replaced by applying a generous layer of glue. With this trick you can reduce paint consumption. Just keep in mind that in this case the mesh structure of the web will be noticeable. This will be impossible to change even if you apply many layers of paint. Smooth surface will not work.
Fiberglass has many advantages, but there are also some minor disadvantages to consider. When cutting the mesh, small particles of fiberglass appear. Getting on open areas bodies, mucous membranes, they cause severe irritation. Therefore, work is carried out exclusively in special clothing and respirators.
But such minor shortcomings cannot cancel out the advantages that fiberglass web has. Its use allows you to avoid many unpleasant moments in the future. In addition, its pasting does not require special skills.
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 in front of finishing works. 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 the house shrinks over time, painting fiberglass cobweb, 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 coating for walls is gaining popularity in the market today finishing materials, and with quite serious speed. 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 there is no need to remove it from under the finishing material.
- 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 and 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.
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 making interior works.
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.
As a result, it is possible to achieve more High 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 in finished form, 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.
Preparing surfaces for painting is a complex matter that requires highly qualified. But even this does not always save from the appearance of large cracks— the house is sinking, the plaster is drying unevenly. As a result, we have small tears that spoil appearance. Painting fiberglass is a material that makes it easier to prepare surfaces for painting and also serves as protection against small cracks.
Painting fiberglass - what is it and why?
When the building shrinks or the plaster/putty dries, small cracks form on the walls and ceiling. They greatly spoil the appearance of painted surfaces. To prevent their formation when plastering, use a painting mesh. It reinforces finishing materials, preventing the formation of large cracks. Microcracks are combated with the help of painting fiberglass. It's thin non-woven material made from multiple glass fibers different thicknesses. The fibers are connected randomly to each other, which prevents cracks from appearing. There may be microcracks, but they are not visible. This determines the scope of application of painting fiberglass - to improve the quality of finishing of walls and ceilings.
To keep painted surfaces even and smooth, use a “cobweb”
The thickness of this material is small - it is translucent. Because of its appearance it received the name “cobweb”. Sold in rolls 1 meter wide, with different densities - from 20 g/m2 to 55 g/m2. The density is selected depending on the application. For interior work, 30-40 g/m2 is more often used.
Fiberglass is glued with glue for glass wallpaper onto more or less smooth walls. It successfully masks small cracks (up to 0.5 mm wide) and unevenness, creating a smooth surface. That’s why this technology is becoming more and more widespread - it simplifies the preparation of walls for painting (putty), and the result is no worse. The same material can be glued to drywall. It successfully masks joints and prevents the formation of cracks in these places. The main thing when gluing is to place the seams of fiberglass away from the joints of the gypsum board.
Painting fiberglass is inconvenient to work with - the fiberglass breaks, and its smallest particles can get into the lungs. Therefore, you need to work in protective clothing and, preferably, a respirator. After it is glued and hidden with several layers of finishing materials, there is no question of any migration of fiberglass. In this state it is absolutely harmless.
Methods of application
Glue the painting fiberglass onto a flat surface gypsum plaster or per layer starting putty. According to the technology, alignment is required after gluing thin layer finishing putty(for stripping), then primer, and then paint. With this sequence of work, paint consumption is minimal; for a good result, 2 layers of paint are enough. Despite the additional cost of putty, if you are using expensive paint, it is better to stick with this technique. This method is also used if the paint is glossy or semi-gloss.
There is another approach. The cobweb is glued and painted after drying. No puttying. The end result is a good result - a slightly structured surface with a slight “hairiness”. But it takes a lot of paint, and for a normal result you have to apply at least 4 layers. The first pass, the paint is absorbed very quickly, the consumption is 3-4 times more than normal. At the same time, the appearance of the wall is unsatisfactory: in some places there is not enough paint, in others - where we went over one place with a roller several times - there is a lot of it.
The second coat of paint takes almost half as much and looks a little better. Consumption continues to decrease, but not at the same rate. After 4 layers, the appearance of the wall is already normal, but the total amount of paint composition is impressive.
To reduce paint consumption, after gluing, coat the painting fiberglass with a primer. Can be done in two layers. It will take a lot of primer, but much less paint. Moreover, even the first layer will lie well. For a good result, you will need 2-3 layers, but with normal consumption. So this method is also not bad, but it can be used with matte or semi-matte paint.
Bonding technology
Painting fiberglass canvas is glued to glass wallpaper adhesive. It is important that the glue is good, but it does not have to be expensive. The gluing technology is very similar to wallpapering:
As you can see, nothing complicated. Only all operations must be carried out carefully, achieving best result that you are capable of.
There are several nuances regarding working conditions. There should be no drafts in the room, the temperature should not be lower than +15°C, humidity should be within normal limits. Keep doors and windows closed until the glue dries. If the sun is hot, it is better to curtain the windows. That's all, actually.
