Fiberglass instructions from the manufacturer. What is fiberglass and does it need to be puttied? General concept and advantages of fiberglass

Fiberglass for puttying is a simple, fast and proven way to give strength to the interior decoration of walls and ceilings, and level them, at the same time making additional reinforcement. Gossamer, as builders call fiberglass, is made by pressing and is a translucent panel, usually rolled into large rolls.

The opinions of experts on the need to level the gossamer differ, some of them believe that gluing the canvas is enough, while most builders are convinced that puttying the fiberglass is essential.

The latest trend in modern finishing works is the gluing of fiberglass before the final stage of decorative wall decoration. The material gained popularity because of its useful qualities, but not everyone came to a consensus on how to use it and how to cover it after gluing, paint fiberglass immediately after gluing, or pre-apply a protective layer on it.

The need to use fiberglass when working with drywall was dictated by the occurrence of cracks in this building material, which mainly appeared at the joints, along the seams. Previously, a sickle mesh was used, but it turned out that it does not provide sufficient guarantees of strength and does not always prevent the formation of cracks, especially if they appear under the influence of building shrinkage or sudden temperature changes. The trend towards the use of fiberglass appeared in order to avoid such a nuisance.

By itself, the building material is torn quite easily, because it is made of thin strands of fiberglass, fastened together by an organic compound. However, on the wall, such a canvas acquires non-analogue reinforcing properties and helps to ensure the integrity of the finished wall coating for a long time.

The main advantages of the material

Gossamer or matting, as fiberglass is called in professional slang, has a lot of invaluable properties that led to its widespread use:

environmentally friendly, because it is made from natural materials;
has increased strength and exceptional wear resistance;
practically not subject to temperature and mechanical damage;
does not accumulate static electricity and therefore does not attract dust;
does not cause any allergic reactions in the inhabitants of the dwelling;
possesses exceptional fire resistance, does not ignite and is often used for finishing passages that provide evacuation of people in case of fire in large buildings;
in the role of a reinforcing frame, it absorbs the finishing material and gives it exceptional strength;
does not contain any nutrients for fungus and mold, is not exposed to their harmful effects.

There are no disagreements about the use of cobwebs in finishing work done with cutting-edge materials. The main subject of controversy is whether it is possible to immediately paint the reinforced surface or is the use of putty absolutely necessary?

How necessary is fiberglass putty?

People who do not have special knowledge, and especially those who move into a new room where interior decoration must be done on their own, often wonder whether it is necessary to putty already finished fiberglass or is it quite enough just to paint it. After cracks appear on the surface of the newly finished walls and ceiling, and tears and bubbles appear on the pasted wallpaper, it becomes clear that this was necessary. Especially when, when trying to remove the warped wallpaper, the cobweb will follow them.

If painting or wallpapering was done directly on fiberglass, the fiberglass texture, seams, and joints, which in this version will remain uncovered, will definitely be noticeable. This will give a freshly finished room a not very neat look.

Fiberglass for putty should be purchased dense enough, this will simply further enhance its reinforcing properties. Such material is more expensive than thinner, but this is not the option on which you should look for a way to save money. Re-repair when the thin gossamer fails will be much more expensive than the small difference in price between denser and denser pressed material.

Material selection

Both the putty and the fiberglass adhesive must be of the highest quality, each layer must be completely dry, and only after that can the next one be applied. To solve the problem, than to putty, you can purchase two types of material or use a universal ready-made composition. It can be applied at any stage, so as not to think about whether I putty with the same composition.

The web, despite its slang name, should be acquired quite dense, and it is necessary to consult with a specialist what kind of density is optimal in order to stick it in specific conditions (private house, apartment in an apartment building, new building, secondary housing).

Glue on fiberglass takes more, because this building material is highly absorbent, and its consumption is much greater than that of glass.

Surface preparation

The main step in gluing fiberglass is cardinal surface preparation. Glue fiberglass should only be on the prepared wall and stock up on the necessary tools and materials.

The main part of the preparatory stage consists in applying a layer of putty on drywall and then sealing problem areas with putty. These include joints, chips, mechanical damage, corners and fasteners.

Compliance with technological standards is a rather complicated process, but still it does not constitute much wisdom and even a non-construction specialist can carry it out:

Before puttying, it is recommended to clean the application sites, especially if other work has been carried out in the room before.
Puttying the wall under the fiberglass should be done with the utmost care, trying to ensure that the places of sealing do not differ in convexity in relation to the rest of the wall.
Seams should be sealed especially carefully, using a spatula and additional grinding, creating the most even surface.

If, on the other hand, damage or joints require a significant layer, and the putty sticks out strongly, so that it can hardly be repaired by sanding, an additional layer is applied over the entire surface of the wall.
Before you start gluing the fiberglass, it is necessary to finally sand the dried layer of putty mixture and remove dust and plaster contamination from the rest of the surface. Experts recommend doing this with a damp sponge and a vacuum cleaner.

The application of a new leveling layer on it, as well as the quality and safety of the final finishing coating, depend on how evenly the surface will be finished on which the reinforcing base will be glued.

Sticking fiberglass

For quick and accurate installation of fiberglass on the ceiling, mark the roll according to the required length, and cut the pieces in advance. Glue must also be prepared in advance, if, in order to save money, it was purchased not in finished form, but in the form of a concentrate.

When making the composition at home, you must follow all the instructions indicated by the manufacturer. Protective clothing must be worn to prevent fiberglass particles from getting on the skin, and be armed with a brush-brush for applying glue. It allows you to initially apply a thick layer, which is necessary, given that fiberglass absorbs glue in large quantities.

When everything is prepared in advance, the process moves quickly:

The first layer is glued from the corner, the surface is leveled by hand.
A smoothing spatula removes air and excess glue.
If necessary, excess fragments are removed with a construction knife.
Glue is applied to the wall, and after laying the cut fragment - on its surface.
The process is carried out continuously - pasted one sheet, followed by a second joint, and so on.
At the inner and outer corners, the material is slightly trimmed so that the tear line is not uneven.
It is important that the joints of fiberglass and drywall fall in different places, otherwise the seam will certainly crack.

The glued material dries for at least a day in a room where the possibility of drafts is eliminated. Before leaving the walls to dry, you should definitely inspect the reinforcing layer for flaws and eliminate them. On the finished wall, every bald spot and bulge will be visible.

Important nuances

If the finishing is not done by hand, but by craftsmen interested in finishing it as soon as possible, they may insist that the surface can already be painted. If you do not putty fiberglass, then paint on it will have to be applied 5-6 times more, because fiberglass has a high absorption capacity. For wallpapering, it is all the more necessary to prime the fiberglass and apply a putty layer, because the entire texture of the glass fibers will be clearly visible, and the wallpaper paste will also go away unmeasured.

Painting fiberglass gossamer - a popular option for repair and finishing materials made of fiberglass. You can remember another similar material, the so-called fiberglass wallpaper - but this is a ready-made finish and it is suitable for even walls. And if the walls need to be leveled, cracks removed, then the fiberglass gossamer will cope with this better and faster than plaster. It is a thin (25–50 g/m2), opaque and pliable canvas, which, thanks to its texture, perfectly strengthens and levels the walls before painting.

How is fiberglass cobweb made?

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

Why do you need a fiberglass web?

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

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

Where can it be applied?

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

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

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

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

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

Why fiberglass is preferred: about the benefits

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

The practice of using gossamer fiberglass shows that it has:

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

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

The price of a cobweb for repairing walls for painting

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

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

In any case, it is an ideal option for developers and refurbishers who want to get an effective result quickly.

The choice of glue for cobwebs

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

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

How to use the web: conditions

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

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

Preparatory work

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

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

Cutting and gluing the first sheet

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

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

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

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

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

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

Shutdown

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

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

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

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

Canvas Safety

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

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

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

Spider web for volumetric ceilings

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

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

What if there is still a crack?

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

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

If the fiberglass is damaged

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

Good results saving time and money

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

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

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

Fiberglass has many advantages, and therefore is often used in interior decoration. about its features, varieties, as well as how to glue fiberglass, we will consider further.

General concept and advantages of fiberglass

Fiberglass is an environmentally friendly and harmless material that is created on the basis of mineral fiberglass and organic resins. It appears as a continuous non-woven fabric, without a pronounced texture, which has the highest tear strength.

Fiberglass, also called a paint cobweb, because of its specific surface and soft structure. In composition, it is similar to cullet, but has a number of features in which it differs from them. Fiberglass fibers do not intertwine like glass fiber, but simply randomly glued together in a chaotic manner.

The production of fiberglass is not associated with machine tools; fiberglass is pressed during its manufacture. This process is similar to the production of paper. Ultimately, the manufacturer receives a very smooth sheet with a minimum density. The difference between fiberglass and ordinary paper is that fiberglass is not affected by moisture, chemicals and mechanical influence, static electricity and dust do not accumulate in them, they perfectly reinforce the surface of the walls.

The similarity of fiberglass with paper is in the transmission of air, environmental friendliness, harmlessness to health, anti-allergic and antiseptic. The difference between fiberglass and glass fiber is the smoothness of the surface, which is subject to repeated staining.

On plastered walls, in the process of shrinkage or the influence of high temperatures, the finest network-like cracks appear, which destroy its integrity and become noticeable only when the walls are wet. If such walls are reinforced with fiberglass, then cracks will not appear, and the surface will become clean and smooth.

Fiberglass is also used to increase the strength of paint, which is applied to the surface of walls or ceilings. In this case, the paint acquires new properties, it becomes non-combustible, stronger and more water-resistant.

The main functions of fiberglass gossamer are:

elimination of small irregularities and smoothing the surface of walls and ceilings;
reinforcement of small cracks;
subsequent application of the finish;
increasing the strength of the surface on which the fiberglass is applied.

Among the advantages of fiberglass, the following qualities should be highlighted:

fire safety,
anti-corrosion,
antiseptic,
ease of care
air passage,
anti-allergic,
does not store electricity
harmlessness.

Among the large number of advantages, there are several disadvantages of fiberglass:

fiberglass is hard to work with
fiberglass will not cover large cracks, they must first be repaired,
in the process of its use, overalls, a mask and a respirator should be used so that small glass particles do not get on the mucous membranes and do not irritate the skin.

Scope of fiberglass

The use of fiberglass is associated with the interior decoration of residential or public premises. It is used for decorating and reinforcing walls or ceilings. Due to the presence of a dense structure, all irregularities are easily masked and the paint is perfectly applied.

The use of fiberglass during finishing work allows you not to use finishing putty on the walls, it is enough to putty them only with the starter.

After the plaster coating on the walls is restored, they need to be puttied, and then treated with a deep penetration primer. The type of adhesive used to attach the fiberglass should be taken into account based on the manufacturer's recommendations.

The adhesive is applied directly to the wall. The canvas is cut off, which has a margin of about eight centimeters and is glued in a vertical direction. It is advisable to use a plumb line to mark the place where the pasting will be carried out. Gluing subsequent fibers is similar to wallpapering, they are joined to each other. Use a rubber roller or spatula to smooth out any unevenness. Excess fiberglass is cut off with a mounting knife. When the glue is completely dry, and this takes from one to two days, proceed to the staining process.

Due to the fact that fiberglass has a fibrous structure, much more paint is required. To avoid this, you should putty the surface again, but with fiberglass. The consistency of the putty should be liquid, and the application is carried out with a rubber spatula. Putty, as it were rubbed into fiberglass. This procedure is carried out carefully and slowly so that there are no minor errors, since staining will be carried out after it.

The advantage of using fiberglass is that in the process of wet cleaning, using high-quality paint, the surface does not lose its original appearance for many years. Therefore, this material is indispensable in the process of finishing the kitchen or children's room. Also, fiberglass does not burn, perfectly passes air, has antiseptic properties, and most importantly, it is completely safe.

Scope of fiberglass:

production of waterproofing and roofing materials;
production of panels of floor and wall type from polyvinylchloride;
reinforcement of polyvinyl chloride;
drainage systems;
reinforcing base before applying plaster;
in the production of panels, fiberglass gives them a more presentable appearance, improves fire resistance and simplifies their installation;
to protect the pipeline system from corrosion;
when gluing roofing, to improve its quality;
when laying tiles or carpeting;
in the device of floating floors, for the construction of special soundproof screens.

How to glue fiberglass on the ceiling

Tools for work:

building level,
mounting knife,
pencil,
roller,
tassel,
paint bath,
wallpaper spatula,
spatula normal.

Before proceeding to the direct gluing of fiberglass to the ceiling, it must first be prepared for this process. The preparatory stage of work includes the following actions:

1. Remove old plaster, paint, lime or wallpaper from the ceiling. For these purposes, use a spatula. To remove old wallpaper, you need to pre-soak them with water and wait half an hour.

2. If the ceiling is covered with lime mortar, especially if there are several layers of this material on it, it is recommended to clean it with a spatula. So, as the adhesion between the fiberglass and the ceiling will be very weak.

Tip: If the lime ceiling is difficult to clean with a spatula, another treatment option is possible. Using a brush or roller, wet it with water and wash it with a woolen cloth several times.

3. After cleaning, you should begin to close up small cracks and depressions that formed during the cleaning of the surface. Before that, it is recommended to walk along the ceiling with a roller with a primer.

4. It is possible to glue wallpaper directly on such a ceiling, but it is better if the entire surface is plastered.

5. When gluing fiberglass onto a plasterboard ceiling, you must first seal all joints and caps of self-tapping screws and make the surface perfectly flat. Before proceeding to the next step, the putty must be completely dry.

6. If fiberglass is glued to a layer of insulation, for example, extraction polystyrene foam, then surface preparation also includes puttying all joints and dowels with which it is attached to the ceiling.

How to glue fiberglass video:

The process of gluing fiberglass includes:

1. Pre-cutting the sheets to be glued into pieces. To easily join the sheets together, leave one centimeter of stock on each segment.

2. Decide on the place for gluing the first sheet, using a level and a pencil, draw its location. Better yet, make a complete markup, according to which gluing will be performed.

3. Pour glue into the bath and apply with a roller to the surface of the ceiling. Apply such a strip so that it is slightly larger than the area on which the fiberglass is glued. In awkward areas, such as corners or near a chandelier, apply the adhesive with a brush.

4. Then attach the cut piece of fiberglass to the ceiling and level with a rubber spatula. Do not press the edges too hard to easily join them with the next sheet.

5. The second sheet is glued in the same way, the joint is wiped with a dry cloth, and processed with a wallpaper spatula.

6. After gluing all the fiberglass sheets, there should be no drafts in the room. This action will allow it to dry faster and stick to the surface more firmly.

Painting fiberglass - features of gluing on walls

The procedure for gluing painting fiberglass on the walls begins with their preparation and complete cleaning. Then the walls are leveled and covered with this material.

Consider the phased application of fiberglass:

apply a rough starting putty to the surface of the walls;
wait for it to dry completely and treat with a deep penetration primer;
after the primer has dried, apply glue with a roller;
start gluing the first sheet from the corner;
to improve the reinforcement of the surface, iron along the edges of the fiberglass with a roller;
pay special attention to the joining of two sheets - apply one sheet to the other with a gap, and then use a mounting knife to cut the joint and remove the excess fiberglass;
the joint must be smoothed with a spatula;
when the wall is completely dry, you need to cover the wall with finishing putty;
after it dries, treat the wall with an abrasive mesh;
apply a primer and start decorating the surface.

Tip: apply glue about one millimeter thick so that it saturates the wall and evenly spreads over the surface.

If the fiberglass is glued with high quality and correctly, the walls seem perfectly even. It is an excellent basis for finishing with decorative plaster. Subject to all technologies, cracks, fungus and mold will not appear on the walls.

Painting fiberglass painting

It is possible to use unpainted fiberglass, as this material looks very aesthetically pleasing. But, if you need to paint the walls, fiberglass is an excellent material, which, in addition to providing a perfectly flat surface, also increases the adhesion of the paint and the wall.

Advantages of using fiberglass for painting:

if you need to drive a nail into the wall, the plaster will not pour out of the hole;
complete absence of cracks.

If fiberglass is used, which is intended for further painting, it is recommended to use water-based paints. Thus, the material will not lose its properties, and after a while it is possible to repeat the staining procedure.

Among the choice of paint tone, it is better to give preference to semi-gloss. The question of direct puttying of fiberglass depends on what type of finish will be used next. If desired, in coloring and obtaining a smooth surface, the fiberglass must be puttied, otherwise it must be immediately covered with paint.

To save on paint consumption, it is cheaper to first cover the fiberglass with a layer of ordinary glue, and then paint it.

In the process of staining is used:

roller,
brushes,
winglet,
bath.

The minimum number of layers is two. The interval between them is twelve hours.

The wing is used for rolling seams, as the roller is not able to evenly color this part.

2. Be sure to determine the front side of the fiberglass, as it practically does not differ from the wrong side. To do this, study the label of the material.

3. Wear long-sleeved gloves, a respirator and goggles to avoid getting small glass particles in your nose or on your skin.

4. When gluing fiberglass onto a drywall surface, make sure that the seams of this material do not coincide with the seams of the drywall sheets. Otherwise, the surface will lose its aesthetics and the seams will be very visible.

5. The optimum temperature for gluing fiberglass is from 18 to 25 degrees. The absence of drafts is a must.

6. Start work from the side opposite to the door.

Fiberglass video:

Fiberglass gossamer has proven itself as a finishing material and helped to get rid of many problems. Today, even in a 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 they are repeatedly plastered, they will appear again. To change the situation, the cobweb grid is called upon. The popularity of this material is growing more and more. Its use avoids possible problems in the future. And it's very easy to glue. 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, which is pressed from fiberglass filaments. It looks like a grid. This material is made in a rolled way, one meter wide and twenty and fifty meters long. It should be borne in mind that this material is not intended for fine finishing. Its scope is to protect surfaces from cracks.

The web has a density of 20 g/m2 to 60 g/m2. For painting, a grid of lower density is used, for reinforcing a larger one. This material allows you to hide microcracks, and also allows the walls to breathe. The complete naturalness of the material does not violate the environmental situation of the room. When using it, the appearance of fungus is prevented, it does not react with chemicals. It can be applied on objects with high humidity.

Fiberglass gossamer gives 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, a cobweb is 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.

Should know! Fiberglass has two sides - the wrong side and the front. They differ in their structure, the front side is very smooth to the touch. The wrong side with villi, it is better glued. Although there is a correct division into parties, but if they are confused, then there will be no special consequences. The main thing is to observe the right amount of glue and firmly press the material to the surface.

Adhesive mixture

Glue for the "cobweb" should be selected correctly. It needs a special one that is designed specifically for this purpose. Trying to save money and use other types of glue is not necessary. This can lead to consequences that could not be expected.

Glue is applied thickly, but without frills. It is very convenient that if there is not enough glue, and the mesh is already pasted, then you can smear it on top - soak it. The cobweb mix has the following advantages:

glue is completely environmentally friendly;
does not leave stains and marks;
final setting time - 2 days;
does not respond to cold.

Rules for applying a web grid

To glue a cobweb, special skills are not needed at all. It is important to follow the rules, which are quite simple. But if there is no experience, then it is best to practice a little. Do not immediately take on large amounts of work. A little patience, and soon everything will turn out like real masters.

VIDEO: how to work with fiberglass

The process of applying fiberglass can be divided into several stages. Much 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.
Glue is applied to the wall or ceiling. You should not feel sorry for the glue, but you do not need to use it a lot either. The fact is that the process of applying the grid is very similar to the wallpaper sticker. The same rules apply here.
A pre-prepared cobweb of the desired width is applied to the surface. It is best to observe the correctness of the front and back sides.
Fiberglass is well smoothed. If it does not work with your hands, then you can use a soft cloth. Using a spatula, the remaining air is expelled. 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. Glue is applied again. Well impregnated sheet becomes dark.
The subsequent sheets should be properly glued with an overlap. Drafts should be avoided. Otherwise, all the work will go down the drain.

If the outer and inner corners are not ideal, then it is best to cut the mesh in these places. Then you can avoid the appearance of voids. Cracks that are in the corners must be sealed with tape (paper). So you need to do in the places where the walls and ceiling are joined.

Fiberglass and drywall

If the surface is made of drywall, preliminary preparation is required. All seams must be sealed with putty. It is important to know that the joints of drywall sheets and mesh should not match.

Unlike simple walls or ceilings, when the cobweb is glued with an overlap, drywall must be glued end-to-end. Trimming should also be avoided. If this is not observed, then 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 supposed, then it is better to use putty - finely dispersed. It should be applied in several layers. Allow each layer to dry completely. After that, you can start grinding using the sandpaper. We must not forget that, as with simple painting, you must first prime the walls or ceiling.

Now more and more often they skip the stage with puttying. This is replaced by applying a generous layer of glue. With the help of such a trick, it will be possible to reduce the consumption of paint. It should only be borne in mind that in this case the mesh structure of the cobweb will be noticeable. This will be impossible to change even if many layers of paint are applied. A smooth surface will not work.

Fiberglass has many advantages, but there are also minor disadvantages to consider. When cutting the mesh, small particles of fiberglass appear. Getting on open areas of the body, mucous membranes, they cause severe irritation. Therefore, work is carried out exclusively in special clothing, in respirators.

But such minor flaws cannot cross out the advantages that gossamer fiberglass has. Its use allows you to avoid many unpleasant moments in the future. In addition, its pasting does not require special skills.
