How to apply fiberglass. Painting fiberglass (spider web): areas of application, cost, installation technique, practical tips for beginners

If the basis for wallpaper is created by weaving fiberglass threads on looms, then fiberglass web is obtained by stamping. The arrangement of threads in such a fabric is chaotic; they are glued together randomly using organic resins.

The material is produced with varying degrees of density: from 25 to 65g/m2. It is very light, which is why it is called cobweb. The least dense fiberglass is used for finishing ceilings, the heavier one is used to reinforce wall putty or as a finishing material for painting. Painting fiberglass has no patterns, therefore it is a very good basis for repeated coloring different ways for the purpose of obtaining smooth surface.

Area of ​​use

The web is easily attached to any surface; it is actively used in the process of new construction and for more convenient repair work. What is fiberglass used for?

1. Thanks to its excellent reinforcing properties, it effectively strengthens the surface for finishing. If low-quality drywall is used as a leveling material, then fiberglass will make such a surface durable and reliable. The use of fiberglass does not exempt the use of serpyanka when sealing joints.
2. It can replace the last layer of starting putty or the entire initial putty, depending on the condition of the base.
3. The use of fiberglass helps prevent the occurrence of cracks and cavities. Makes conditions for fulfillment finishing more comfortable.
4. The cobweb is used as a strong base for painting if it is intended to make the wall or ceiling smooth, without relief patterns.
5. It is very convenient to repair with fiberglass those sections of walls or partitions that are covered with small cracks.

In addition, fiberglass has found its application in the production of wall panels, floor coverings. It is often used in roofing work and for pipeline protection drainage systems, and also as one of the components of the waterproofing pie.

How and what to glue cobwebs on

The process of gluing fiberglass to the surface of the wall and ceiling is not much different from working with wallpaper and depends on the final purpose of using this material. In any case, you must first perform basic leveling and rough preparation of the wall or ceiling surface.

Next you need to perform impregnation priming deep penetration and then decide what to glue the fiberglass onto. Correct selection glue - the procedure is very important, since the strength of fixation and service life of the finish depend on the quality of the adhesive composition. You should use only special formulations from well-known brands, for example, Wellton, Pufas, Bostik. They contain components High Quality and completely harmless to humans. Glue for fiberglass when hardened forms a film that prevents the formation of mold and fungal manifestations.

The sticker process consists of the following steps:

• a roll of fiberglass - the webs are unrolled and cut into sheets of the required size;
• the adhesive composition is applied to the surface of the wall or ceiling using a roller, spatula and brush;
• the first canvas is glued from the corner to the center, it must be tightly smoothed and leveled with a plastic spatula;
• web webs are glued end-to-end; if it is necessary to make a small overlap, then after gluing it is cut through sharp knife and remove excess to strengthen the reinforcing purpose of the material.

After the surface is completely finished with cobwebs, it is covered with a layer of the same glue, only in a diluted state. This layer serves good reason For finishing putty or staining in several stages. But by itself it does not create an absolutely flat surface, since the glue easily penetrates between the glass fibers. Now you should wait for the wall or ceiling to dry and you can begin further work.

Final finishing

Fiberglass for painting can be used immediately after the glue has dried. However, this process cannot be called too simple in terms of labor intensity. You will need to apply several layers of paint to ensure the surface is completely flat and smooth. Because the first layers of the coloring composition will penetrate between the threads of the web, thereby creating uneven coloring.

However, you can go the other way - before painting, cover the fiberglass with one or two layers of finishing putty. It will hide all the unevenness and save on the consumption of expensive paint. Properly applied fiberglass under putty will help create an ideal and very durable surface. Will protect it from occurrence shrinkage cracks and will extend the service life of the cladding.

When decorating premises, many do not want to give up such familiar materials as paper, vinyl, non-woven or some other wallpaper. At the same time, they ask the question: is it possible to glue wallpaper onto fiberglass? If the walls of your house are made of wood, lined PVC panels, composite boards such as chipboard or fiberboard, using insulation, then fiberglass is not only possible, but absolutely necessary. For better adhesion of the wallpaper to the surface reinforced with fiberglass, it must be covered with putty. After drying, treat with a primer and you can stick any wallpaper. They will hold firmly and last a long time.

When working with glass materials, one must not forget about safety rules. You should work with gloves and, preferably, use safety glasses and a respirator. This is necessary to ensure that glass fluff does not accidentally get into the respiratory tract or eyes.

Not everyone knows what paintable fiberglass is: this innovative finishing material appeared on the market relatively recently and is actively gaining popularity due to its valuable properties. Like other types modern materials, painting fiberglass web provides previously unavailable advantages in the process of finishing work.

Area of ​​application of the material

What it is? Fiberglass is a non-woven fabric obtained by pressing and consisting of the smallest glass fibers. This is a thin translucent material, therefore, in professional jargon, painting fiberglass is often called gossamer.

Why do you need painting fiberglass? It guarantees the avoidance of visible damage to walls and ceilings. The appearance of cracks on surfaces covered with plaster and putty is not always associated with the unprofessionalism of the workers who carried out the repairs. Cracking is due to physical properties traditional building materials that shrink over time when exposed to dry air.

Another reason for the appearance of cracks is constant vibration, which is typical for houses located next to a highway or railroad. Due to the appearance of cracks, previously it was necessary to frequently renew the decorative coating.

The use of fiberglass allows you to obtain perfectly smooth, durable and crack-resistant walls and ceilings.

Hypoallergenic, Fire safety, ease of use, durability and the ability to transmit water vapor, thanks to which the decorated surfaces have optimal humidity, determine the increasingly frequent use of gossamer for reinforcing walls and ceilings.

Specifications

Painting fiberglass - lightweight fibrous material, obtained from natural raw materials, which serves quartz sand.

Fiberglass web is supplied in rolls, the length of the canvas is 50 m, width 1 m.

The density of fiberglass varies from 25 to 50 g/m2.

It is better to choose fiberglass of higher density for walls, and lower density for ceilings.

The material can be used at temperatures from - 40 to + 60 ° C, which makes it suitable for any climatic conditions.

The web is breathable and hygienic: it does not electrify, does not accumulate dust, can withstand wet cleaning, and does not form mold or mildew. The material does not emit harmful substances into the air and does not support combustion. All this, coupled with resistance to mechanical damage and the possibility of quick application, gives the web an advantage over other types of finishing materials.

Precautionary measures

Fiberglass web forms a hard, wear-resistant coating on the wall that can be washed, but it acquires these qualities only in combination with glue. Before we talk about putting it on the walls, you should take precautions.

The material that has not yet been glued is quite fragile, and its small particles can get into the respiratory tract. Once on the skin and mucous membranes, glass fibers cause irritation, so when working, be sure to use a respirator, safety glasses and protective clothing.

You can glue cobwebs only at a certain temperature (from + 15 to + 25 ° C) and air humidity of no more than 60%. During work, drafts are not allowed; direct sunlight must be avoided.

How to glue glass fiber correctly? It is necessary that the walls are pre-leveled and puttied. Before gluing, you need to carefully putty and reinforce the seams between the slabs and then ensure that they do not coincide with the boundaries of the glass panels. Fiberglass canvas is glued to putty only after using a deep penetration primer, which will avoid overuse of adhesive.

The technology suggests that cobwebs can only be glued special compounds that do not contain starch, for example, Bostik, Oscar, Wellton adhesives produced by fiberglass manufacturers. The same compositions

It should be taken into account that the material has a reverse and smoother front side: It is important not to confuse.

Rules for gluing

The material should be glued as follows:

• cut the material into strips according to the height of the walls with an allowance of up to 10 cm;
• According to the instructions, prepare a solution from the dry substance - the preparation time should not exceed 15 minutes ( ready solution also sold, but it is much more expensive);
• Apply glue evenly without gaps to the wall or ceiling - you need to cover with glue an area slightly larger than the width of the first canvas;
• strictly vertically, pressing with a roller or a flexible plastic spatula, glue the first canvas - pasting begins from the corner closest to the window, the canvas is positioned end-to-end;
• apply the next portion of glue and attach the second canvas overlapping - for the paint to look even, the pile on the canvases should be directed in one direction;
• use a stationery knife to cut off the excess under the ceiling, above the floor and exactly along the joint (to make it smooth, it is convenient to press a wide spatula to the borders and cut along its edge);
• Cover the glued canvases with glue on top - you need to stop when the color becomes uniform.

The video will show you how to glue fiberglass sheets to the ceiling.

It is important that the room remains closed until the glue has completely dried. A draft can completely destroy the results of the work, causing the paintings to peel off.

How to prepare fiberglass for painting

Craftsmen are often interested in questions: is it necessary to prime fiberglass, and is it necessary to putty fiberglass and why is this done? There is no need to prime the coating before or painting, because the walls have already been primed before gluing it on. In addition, the glue acts as a primer.

The question of whether puttying is necessary does not have a clear answer. Fiberglass has a beautiful texture, which is sometimes preferable to preserve, but the paint consumption will be very high and at least 4-5 layers will be required. Paint will make the joints noticeable: even if they are made perfectly, their mere presence will not at all decorate the room. It is better to putty fiberglass before painting for another reason: small fibers can get into the air, which is harmful to health, and putty completely prevents their penetration.

What to putty on? There is no special putty for fiberglass; you can use any finishing mixture on gypsum or polymer based, the main thing is that it is of good quality.

How to putty painting fiberglass? The technology has some features:

• by the time the putty is applied, the glue must be completely dry;
• if the coating was pasted several days ago, it needs to be cleaned of dust;
• the adjacent surface is protected with masking tape;
• putty is applied in two layers with an interval of 24 hours;
• the thickness of the first layer should not exceed 2 mm;
• the second layer should be just as thin and completely cover the first;
• After drying, the putty is sanded using a block of sandpaper with a grain size of no more than P150.

Fiberglass putty allows you to get a perfectly flat, durable surface.

Painting fiberglass

How to paint fiberglass? If you decide to paint fiberglass without prior puttying, you will not need to prime it, but its texture will be visible even under many layers of paint. Still, painted walls or ceilings will have a more attractive appearance if they have been previously puttied; in this case, you need to apply a primer. To paint walls, it is better to choose water-based paints that adhere well and are easy to work with.

Fiberglass is painted using the same technology as other materials.

The paint is applied with a roller until there are no areas of uneven tone left on the painted surface.

Is it possible on fiberglass? Yes, because this material is not a finishing material. Fiberglass for wallpaper is a common finishing option, but before final finishing the surfaces need to be puttied and primed.

Fiberglass is rarely used as decorative covering, but as a reinforcing material it is indispensable. Its use will allow you to achieve a perfectly smooth surface, and redecorating won't take much longer.

Development construction technologies contributed to the introduction of innovative solutions to create new multifunctional building materials that simplify work during the construction and finishing of buildings for various purposes.

A bright representative modern building materials with a wide range of functions and a diverse range of applications is fiberglass, made from ultra-thin glass fibers with a diameter of 10-18 microns.

He owes his popularity to availability of raw materials And ecological cleanliness its components - quartz sand, clay, limestone rocks and glass scrap in the form of cullet.

The use of recycled glass raw materials allows us to successfully solve issues of maintaining the proper level of cleanliness environment and obtaining relatively cheap building materials such as fiberglass or glass wallpaper.

The basic raw material for the manufacture of fiberglass fabrics is glass elementary fiber filaments, obtained by drawing molten glass mass through platinum dies.

The production of fiberglass is based on the same principle, which you can read about.

Components of natural origin (quartz sand, clay and limestone) and glass recyclables based on cullet.

The addition of cullet to a mixture of raw materials, called a charge, significantly saves material and energy resources used for the production of fiberglass.

By processing one ton of cullet, more than one ton of the main natural raw materials is saved, including the following materials:

• quartz sand – about 650 kg;
• soda ash - about 185 kg;
• limestone - almost 200 kg.

For every 10% added mass of cullet heat and electricity consumption is reduced by 3%, since melting a charge composed entirely of natural components requires a higher temperature than a charge containing cullet.

With the introduction of 40% cullet, energy savings will be 12%, which significantly affects production efficiency.

In total, about 3 million tons of fiberglass are produced in the world.

Leading fiberglass manufacturers pay increased attention to glass recycling.

Presence of cullet among the components of produced glass fiber reduces the amount of pollutants removed into the atmosphere, allowing the manufacturer to save on emissions treatment equipment.

You can read about other ways to recycle cullet and their benefits.

Differences from glass wallpaper

The technology for producing canvas from glass fibers is fundamentally different from the production of glass fabrics:

• fiberglass is obtained by pressing glass fibers randomly located under the press;
• fiberglass fabrics are woven on textile weaving equipment.

After pressing glass fibers, fiberglass is formed - thin smooth material without a pronounced pattern, resembling sheets of paper.

From glass raw materials, fiberglass “inherited” its basic properties - chemical inertness, resistance to open fire and other qualities that made it one of the most popular construction and industrial materials.

In accordance with the production technology, fiberglass differs from glass wallpaper in terms of surface density and functional purpose:

• the density of fiberglass does not exceed 50-65 g/sq.m, which allows it to be confidently used for covering ceilings;
• the density of glass wallpaper exceeds that of fiberglass and is 150-225 g/sq.m;
• fiberglass is a finishing material for covering walls and ceilings, requiring subsequent finishing painting; thanks to its smooth surface, fiberglass can be repainted multiple times without deteriorating the quality of the coating;
• Glass wallpaper is a finishing decorative coating that does not require painting.

With repeated repainting, the surface quality of glass wallpaper deteriorates significantly.

This is exactly what it is very important difference between them and fiberglass.

Thus, it is up to you to decide what is better to use for painting: fiberglass or wallpaper.

If you plan to repaint the coating several times, the choice is obvious.

You can read more about glass wallpaper and its differences from fiberglass in the article.

Areas of application

In Russia, more than 200 million m² of fiberglass is used annually. In construction and industry, it is used in combination with other materials that are selected in accordance with purpose And technical requirements to the final product/object.

So, what is fiberglass used for:

1. Production waterproofing coatings , in which glass fabric sheets serve as the basis for applying bituminous impregnating compounds (roofing). In construction practice, bituminous coatings are used in the form of rolled roofing materials and soft bitumen shingles.
2. Production of linoleum, in which fiberglass is used as a supporting frame that prevents shrinkage of the linoleum.
3. Manufacturing, in which fiberglass serves as a reinforcing material for impregnation with binders polymer compounds during the subsequent shaping of the product (boat, container, etc.).
4. Construction, repair and finishing works, in which fiberglass is used for:

• creating protective reinforced surfaces of walls and ceilings;
• formation finishing coating walls and ceilings, subject to subsequent decorative painting;
• creating a soundproofing substrate in “floating floor” structures to reduce the level of impact noise.

Soundproofing canvas is a multilayer roll material with a one-sided bitumen-polymer coating, which is used as elastic soundproofing substrate under a cement-sand reinforced screed.

Varieties by density

The technology for the production of fiberglass is based on pressing chopped or staple fiberglass, the result of which is quite soft and flexible non-woven material.

Depending on the size of the pressed elementary fiber filaments (diameter and linear length segments) and the method of connecting fiberglass threads into a panel, the surface density of fiberglass varies from 25 to 450 g/sq. m with a panel thickness of 0.5 to 4 mm.

In accordance with absolute value The density of fiberglass changes its operational purpose. With the increase of this technical specifications the indicators of its mechanical strength increase proportionally.

Currently three groups are designated fiberglass, combined by density indicators, set of functions and scope of application.

From 25 to 65 g/m²

They are produced using wet pressing technology, identical to the manufacturing process of smooth paper sheets.

Canvases of this group are used for finishing walls and ceilings, for which they are called painting fiberglass canvases.

A more popular name for the materials of this broad group is “cobweb”, which they received because of their translucent texture, reminiscent of an openwork woven web.

For writing paper for copiers and printers, the standard surface density is within 80 g/sq. m. Density of the “web” one and a half to two times lower than a sheet of paper.

To make the “spider web”, glass fibers with a diameter of 10-11 microns are used with a length of the constituent glass fibers of 6-10 mm (data for Spectrum SN 30 brand fiberglass painting canvas was used).

To strengthen the structure during pressing modified polyvinyl alcohol is used.

Another name for painting fiberglass - glass interlining - was assigned to it due to its identity with painting interlining, which is a non-woven paper-like finishing material based on glued cellulose fibers.

From 60 to 200 g/m²

These materials differ from painting “gossamer” in their pressing technology:

• glass fibers are combined using synthetic resin components;
• the fibers are unevenly distributed throughout the volume, forming a rough, rough, uneven surface, while fiberglass has a smooth and soft surface, and the fibers are evenly distributed, without clots or compactions.

Fiberglass canvases of this group have found their application as waterproofing materials, therefore they are often called roofing and bitumen fiberglass (depending on the type of binding component and its quantity).

Outwardly, they no longer resemble a weightless “cobweb”, but look like a dense, opaque fabric with the following characteristics:

• glass fiber diameter – from 13 to 18 microns;
• fiber length – 12-18 mm;
• panel thickness -0.5-1.0 mm.

It should be noted that roofing fiberglass perfectly absorbs moisture And .

The use of roofing fiberglass is regulated by GOST 30547-97 “Rolled roofing and waterproofing materials. General technical conditions".

The most popular brands are::

1. Fiberglass of the Technonikol brand, produced according to TU 5952-001-13344965-2004. The density of the material is 100 g/sq.m, the thickness of the panel is 0.8 mm. The glass fiber used has a diameter of 13-16 microns and a fiber length of 12-18 mm.
2. Fiberglass brand VVG, produced in accordance with TU-21-5328981-16-96 in widths of 200, 400, 1000 and 1200 mm. Max diameter glass fiber is 18 microns. The thickness of the panel is 0.5 mm, the surface density is from 60 to 200 g/sq.m, depending on the type of binder.
3. Fiberglass reinforced grade HSA, produced according to TU 5952-012-04001485-97. Reinforced fiberglass from competing analogues (TehnoNIKOL and VVG canvases) has increased mechanical strength due to glass fiber reinforcement in the longitudinal direction along the entire length of the material in increments of 30 mm. The density of reinforced fiberglass varies from 45 g/sq.m (for the XSA-45 brand) to 115 g/sq.m. m (brand HSA-115). According to HSA specialists significantly superior traditional VVG according to physical and technical parameters and is a more suitable quality basis for applying modern bitumen-polymer coatings.

Fiberglass is also used to create multilayer bituminous roll materials, of which the most popular is glass insulation TU 5774-004-00289973-96 grades K-3.5 (HKP) and K-4.0 (HKP).

The surface density of such coatings is 3500-4000 g/sq.m. m, since it takes into account the weight of the bitumen mixture and other components of glass insulation.

In the practice of marketing bituminous roofing coatings based on fiberglass, such materials incorrectly called bituminous fiberglass.

450 g/m²

This type of fiberglass is called pierced.

They are produced by fastening with knitting and stitching weave several layers of glass fibers with a diameter of 6-13 microns.

The stitching is carried out with glass threads. The formation of the material occurs without the use of binding materials.

The area of ​​application of pierced fiberglass is thermal insulation of building structures and pipeline systems of heating mains.

Accepted name and designation heat-insulating pierced fiberglass PSH-T. The thickness of the PSH-T panel is 2.0-4.0 mm.

Interior decoration

For interior finishing work V residential buildings and public buildings- children's and medical institutions, offices, hotels - painting fiberglass - "gossamer" - is especially in demand.

The “cobweb” breaks easily until it is glued to any surface.

However after glue impregnation in the process of sticking to a wall or ceiling, its strength is comparable to the strength of steel, which allows fiberglass to serve as a reinforcing material.

This feature provides the web with the following functionality:

• strengthening walls and ceilings for preventing cracking processes and the appearance of microcracks;
• increased surface strength, since fiberglass even after application paint coating retains mobility and in the process of many years of shrinkage of the walls of new buildings to a sufficient extent will withstand shrinkage loads to prevent microcracks from growing;
• masking of existing microcracks and hiding defective areas surfaces;
• leveling surfaces of walls and ceilings for painting;
• giving specificity decorative texture covering walls and ceilings for artistic interior decoration and painting.

Advantages of use in finishing works

The main advantages of the “web” include the following factors:

1. Increased fire safety premises covered with glass fiber canvas.
2. Resistance to open flame and high temperatures in the event of a fire in the room, fiberglass can withstand up to 1300 without destruction and does not emit toxic substances.
3. Valuable environmental qualities– cobweb coatings do not emit harmful substances and cannot provoke allergic reactions.
4. High chemical inertness against corrosion, acids and alkalis.
5. Absence conditions for education fungus and mold.
6. Antistatic coating, as a result of which static electricity does not accumulate on the finished walls and ceiling and dust does not settle.
7. Fiberglass is not susceptible to impact dampness and condensation.
8. “Gossamer” does not lose its performance properties with sudden temperature changes.
9. Good strength qualities, preserving the integrity of wall coverings in houses and apartments with pets;
10. Possibility of multiple repainting without loss of decorative qualities.
11. A wall covered with a “cobweb” will not impede the movement of water vapor and air, positively affecting the microclimate of the home.

Summarizing the list of advantages of painting fiberglass as a finishing material, it should be noted that it is fully adapted to modern special requirements to materials for interior decoration of residential and public buildings.

Let us note the following circumstances that are in the foreground of the requirements for interior decoration:

• hygiene coating, which implies the possibility of constant wiping, washing and disinfection;
• antistatic fiberglass material;
• bactericidal properties, allowing the use of “cobwebs” in clinic rooms, kindergartens, swimming pools and baths;
• moisture resistance;
• good acoustic properties in room.

Disadvantages of use

The disadvantages of the “cobweb” include the following points:

• painting fiberglass canvas according to structure is soft and pliable, which makes it very difficult to fix it in one position when pasting walls or ceilings, so it is practically impossible to handle the material alone;
• the difficulty of dismantling an already pasted “cobweb”;
• "cobweb" canvases prevent the spread of small cracks, however simple application on the wall it is not able to “cope” with the elimination of large defects; when eliminating them, it is necessary to carry out preliminary preparation of the walls and putty them, only then glue the fiberglass;
• painting fiberglass without putty 2-5 times increases paint consumption compared to painting a pre-putty “cobweb”;
• the need to work in protective rubberized workwear and protection of the visual and respiratory organs in the process of cutting and gluing fiberglass.

Fiberglass consists of thin glass fibers, which when cutting the canvas break down. Micro-shards of glass become hazardous to skin, vision and breathing.

Types of painting fiberglass

In interior finishing work, the “cobweb” is used as a reinforcing layer, so the front side of the painting fiberglass has a smooth surface, while the back side has a fleecy and rough surface to improve adhesion to the wall or ceiling.

Depending on the surface density of the “web” material divided into three groups:

Pigmented fiberglass of the VPP 200 series produced by Vitrulan should also be included in the category of painting dense fiberglass canvas. It can no longer be called a “cobweb”, since the density of fiberglass is 200 g/sq. m.

A layer of primer paint is pre-applied on the front surface of the material in a factory manner, and on the fiberglass fabric of the Vitrulan VPP 200 Aqua model, in addition to the “primer” layer, a layer of adhesive base is applied on the reverse side of the panel.

Due to the presence of an adhesive composition, Vitrulan VPP 200 Aqua material can be classified as self-adhesive wall roll coverings, because when gluing it just wet it down wall without additional application of another adhesive.

The high density of the canvas allows you to reliably hide wall defects, and pre-applied paint will ensure even distribution during final decorative painting.

One layer of glossy paint is enough for the painted canvas to fit perfectly into the interior of any style.

Algorithm for sticker work

Speaking about how to use painting fiberglass for walls or ceilings, it is necessary to describe the following steps.

Stage 1 - preparation wall and ceiling surfaces (hereinafter referred to as the base), including a number of mandatory operations:

• removing the remains of the old finish from the base;
• cleaning from dust and dirt deposits;
• sealing large cracks and recesses, leveling protrusions;
• priming to ensure maximum adhesion of the adhesive to the base.

Stage 2 - cutting pieces fiberglass for gluing, including the following operations:

• cutting the “web” in accordance with previously made measurements and rough calculations;
• cutting off cut panels from a roll.

It is customary to cut pieces of material into sizes that would be convenient to work with.

Stage 3 - kneading glue. Many craftsmen use adhesive compositions homemade, believing that it costs much less.

Among the “branded” adhesives for glass interlining, practitioners distinguish the following brands:

• Oscar;
• Wellton;
• Nortex.

Stage 4 – direct gluing glass interlining. When wallpapering rooms to create modern interior The so-called “double cut” method is used to obtain canvases glued end-to-end:

• first, two sheets of material are glued overlapping, as shown in the photo;
• the thickenings at the overlap are cut off along the entire length with a knife and removed.

Leading manufacturers

On the Russian market from foreign manufacturers The fiberglass industry is dominated by companies that produce not only painting glass interlining, but also a wide range of other fiberglass products - glass wallpaper, fiberglass, roofing and waterproofing materials.

Among them, the undeniable leadership belongs to the following brands:

1. Vitrulan (Germany) – produces fiberglass in a wide range of fabric densities, ranging from 25 to 300 g/sq.m. For truly “German” quality, buyers of Vitrulan products have to pay high prices - the cheapest “spider webs” cost at least 2,000 rubles/roll.
2. Wellton (Sweden) – workshops that produce painting fiberglass are located in Finland and Germany. Welton products are slightly cheaper than their Vitrulan counterpart (RUB 1,500/roll), but in some cases users there were complaints due to the shedding of the coating.
3. Oscar (China) is a Chinese manufacturer that follows the trend of Wellton products, as it produces them under its Oscar brand. The cost of the “spider web” fluctuates around 1000 rubles/roll.
4. Nortex produces fiberglass in the Czech Republic and China. On the Russian market, Nortex material is sold at a price of 610-630 rubles/roll.
5. TechnoNIKOL is a domestic manufacturer widely represented in the supply of fiberglass materials. increased strength for production premises and roofing insulation. Roofing fiberglass in a roll 9 meters long costs 669 rubles.
6. X-Glass is a Russian company that produces glass interlining at the European quality level. While the range of fiberglass is not wide, it tempts users its affordability. Depending on the density, one roll of standard size costs from 516 rubles. (density 25 g/sq.m.) up to 646 rub. for material with a density of 50 g/sq.m.

Which one is better to choose?

When choosing a painting canvas for use in finishing works, they are guided by: the following circumstances:

• its purpose (for painting, for paper wallpaper or Wall panels and so on.);
• type of surface - wall, ceiling or floors;
• degree of surface dilapidation;
• the type of defects to be repaired (cracks, cavities, bulges);
• the base material on which the fiberglass will be glued - concrete, brick, wood, etc.;

From this video you will learn why fiberglass “gossamer” is needed, which one to choose for certain purposes, as well as the features of gluing walls and ceilings:

Conclusion

The use of fiberglass in repair and finishing work effectively solves problems elimination of minor defects and irregularities walls, successfully replacing the finishing putty and strengthening the surface.

As you can see, the price per roll of painting fiberglass “gossamer” and other types of this material for painting or wallpaper varies depending on the density, which is determined on the basis of grams per m².

The growing popularity of fiberglass materials and their availability in the domestic market creates additional incentives for rational use of natural resources and glass recyclables for the production of much-in-demand finishing coatings, what are “cobwebs” or glass wallpaper.

Now you know more about why fiberglass is needed, what density of material is best to choose for a wall or ceiling for painting, how it differs from fiberglass, and how much it costs.

In contact with

Fiberglass for putty is a simple, quick and proven way to add strength to the interior decoration of walls and ceilings, and to level them, while simultaneously providing additional reinforcement. Gossamer, as builders call fiberglass, is made by pressing and consists of translucent panels, usually rolled into large rolls.

Experts have different opinions about the need to level the web; some of them believe that gluing the canvas is quite enough, while most builders are convinced that puttingtying the fiberglass is extremely necessary.

The latest trend in modern finishing work is gluing fiberglass before the final stage of decorative wall finishing. The material gained popularity because of its useful qualities, but not everyone came to it unanimous opinion about how to use it and what to cover it with after gluing, paint the fiberglass immediately after gluing or first apply a protective layer to 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, serpyanka 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 shrinkage of the building or sudden temperature changes. The trend towards using fiberglass appeared in order to avoid such a nuisance.



On my own construction material It breaks quite easily because it is made of thin fiberglass strands held together by an organic compound. However, on the wall, such a canvas acquires analogue-free reinforcing properties and helps to ensure the integrity of the coating of finished walls for a long time.

Main advantages of the material

Gossamer or matting, as fiberglass is called in professional slang, has a lot of invaluable properties, which 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 home;
• It is exceptionally fire resistant, does not ignite and is often used for finishing passages that provide evacuation of people in case of fire in large buildings;
• acting as a reinforcing frame, it absorbs finishing material and gives it exceptional strength;
• does not contain any nutritional components for fungus and mold, and is not subject to their harmful effects.



There are no disagreements regarding the use of cobwebs in finishing work performed with state-of-the-art materials. The main subject of debate 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 don't have special knowledge, and especially those who move into new premises where interior decoration needs to be done independently, people often wonder whether it is necessary to putty the finished fiberglass or whether it is enough to simply paint it. After cracks appear on the surface of the recently finished walls and ceiling, and tears and bubbles appear on the wallpaper, it will become clear that this was necessary. Especially when, when you try to remove warped wallpaper, a cobweb trails behind it.

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



Fiberglass for putty should be purchased quite dense, this will simply further enhance its reinforcing properties. Such material is more expensive than thinner ones, but this is not an option on which you should look for a way to save money. Repeated repairs when the thin web fails to fulfill its purpose will cost much more than the small price difference between dense and denser pressed material.

Selection of materials

Both putty and glue for fiberglass must be of the highest quality, each layer must certainly dry, and only then can the next one be applied. To solve the problem of what to putty on, 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’m using the right putty or not.



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

More glue is used for fiberglass, because this building material is characterized by high absorbency, and its consumption is much greater than that of fiberglass.



Surface preparation

The main stage of gluing fiberglass is the fundamental preparation of the surface. Fiberglass should only be glued to a prepared wall and stock up first necessary tools and materials.

Main part preparatory stage consists of applying a layer of putty to drywall and then sealing it with putty problem areas. These include joints, chips, mechanical damage, corners and fasteners.

Compliance with technological standards is a rather complex process, but still it does not constitute special wisdom and can be carried out even by a non-construction specialist:

• Before puttying, it is recommended to clean the application areas, especially if other work has been carried out in the room before.
• You should putty the wall under the fiberglass with maximum care, trying to ensure that the sealing areas are not convex in relation to the rest of the wall.
• The seams should be sealed especially carefully, using a spatula and additional sanding, creating the most even surface possible.



• If damage or joints require a significant layer, and the putty sticks out strongly, so that this can hardly be corrected 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, and the quality and safety of the final finishing coating depend on how smoothly the surface is finished on which the reinforcing base will be glued.

Gluing fiberglass

To quickly and accurately install fiberglass on the ceiling, mark the roll according to the required length and cut the pieces in advance. You also need to prepare the glue in advance if, in order to save money, it was not purchased finished form, but in the form of a concentrate.

When making the composition at home, you must follow all instructions specified by the manufacturer. It is necessary to wear protective clothing to prevent fiberglass particles from getting on the skin, and equip yourself with a paintbrush to apply the 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.
• Using a smoothing spatula removes air and excess glue.
• If necessary, remove excess fragments with a construction knife.
• The glue is applied to the wall, and after laying the cut fragment, it is applied to its surface.
• The process is carried out continuously - one sheet is pasted, then a second one is glued into the joint, and so on.
• On internal and external corners the material is slightly trimmed so that the tear line is not uneven.
• It is important that the joints of the fiberglass and drywall are in different places, otherwise the seam will certainly crack.



The pasted 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 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 its speedy completion, they may insist that the surface can already be painted. If you do not putty the fiberglass, then you will have to apply 5-6 times more paint on it, because fiberglass has a high ability to absorb. To glue wallpaper, it is even more necessary to prime the fiberglass and apply a putty layer, because the entire texture of the glass fibers will be clearly visible, and a lot of wallpaper glue will also be used up.

Further a large number of Wallpaper glue may cause damage to the wallpaper when exposed to external conditions. So the question of whether it is necessary to prime and putty is decided positively if the owner wants an excellent look and guaranteed durability of the result.

Even a non-specialist knows how to putty. Ready composition applied with a spatula as the first layer, it is given time to dry, then the second is applied, which is sanded after drying grinder, grater or sandpaper. And only then can you paint or wallpaper.

How to putty on fiberglass (1 video)

It often happens that the repairs made do not last long to please you with their impeccable appearance. Painted or plastered surfaces become covered with a network of cracks, and the wallpaper begins to peel away from the walls and become covered with “wrinkles.” Allows you to avoid such problems preliminary preparation surfaces - reinforcement (strengthening), leveling, applying a composition to improve adhesion - a fairly large amount of work.

They can be replaced by gluing fiberglass based on fiberglass threads. It will strengthen the walls and ceiling and eliminate small cracks. The finishing coating will lie flat and no defects will arise even when the walls of the building shrink.

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







Peculiarities

Fiberglass is used for rough finishing to prevent cracking of the finishing material and its deformation during the shrinkage process. The material is non-woven sheets based on fiberglass threads, which are pressed. The material is produced in rolls 1 m wide. Material length is 20 and 50 m.

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





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

A special feature of the material is the presence of front and back sides. The front side is located on the inside of the roll; it is smoother. The back is more fleecy for better adhesion to the surface.





Fiberglass can be attached to any type of surface, including puttying, painting, and decorative plaster. By preventing cracking of the finish, the material allows the walls to “breathe”.





Advantages and disadvantages

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

The material is hypoallergenic because it is based on natural ingredients(quartz or silicate sand), so it can be used even in children's institutions. Thanks to good vapor permeability, it is possible to obtain “breathable” surfaces.







Among other “advantages” it is worth highlighting the following:

• good moisture resistance, so the material is suitable for indoor use high humidity(bathroom, kitchen);
• fire safety, since the material is not flammable;
• not susceptible to fungi and mold;
• non-hygroscopic material, due to which an optimal microclimate is always maintained in the room;





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





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





The disadvantage is the formation of tiny fiberglass particles that appear during the cutting and installation of the canvas. If they come into contact with the skin, they can cause a burn. This can be avoided by protecting open areas skin, and respiratory organs - a respirator.

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







Kinds

Painting fiberglass can have different densities. Based on this, there are 3 groups of “cobwebs”:







Density 25 g/m2

The material is ideal for gluing to the ceiling for painting, which is why it is also called ceiling. The light weight of the canvas does not put a load on the surface and absorbs less paint. Its use is possible on a relatively flat ceiling with small cracks.





Density 40 g/m2

Universal fiberglass, the use of which is recommended on surfaces more damaged by cracks than the ceiling. Performance characteristics make it possible to use fiberglass of this density for walls, for ceilings, finished with old plaster, as well as on surfaces with high vibration load. The finishing coating is also varied: plaster, paint, wallpaper, which is based on fiberglass coatings or non-woven lining.





Density 50 g/m2 or more

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







Manufacturers

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





Vitrulan

The German company occupies a leading position in the production of fiberglass. Vitrulan is engaged in the production of wallpaper, including water-active ones; the range is replete with materials and tools for painting work, as well as variations of fiberglass. The manufacturer also produces already painted canvases, fiberglass, which imitates fabric textures and has a variety of reliefs.

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





The company regularly updates its product range, offering innovative solutions. So, those who don’t want to bother with glue can purchase fiberglass from the “Agua Plus” collection. It already contains an adhesive composition. You can “activate” it by wetting it with plain water. After this, the glue appears on the surface of the “web”, it is ready for gluing.





Wellton and Oscar

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

The brand boasts a wide range, including both Premium materials and more available options. Among the features are a wide selection of material by density (from 40 to 200 g/m2), the ability to purchase material by the meter, as well as its high performance properties, including the possibility of multiple dyeing.





Along with fiberglass, you can select glue for fixing it from the same manufacturers, which is very convenient.

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

Among domestic manufacturers, the products of TechnoNIKOL, Germoplast, and Isoflex deserve attention. The first manufacturer offers high-strength fiberglass, which is successfully used for the design of industrial premises, roofing insulation, and also heavily damaged surfaces. The advantage of most domestic fiberglass is their affordability.





The Russian manufacturer X-Glass is one of those who produces glass interlining in accordance with European requirements. It is distinguished by its versatility of use, perfectly reinforces surfaces, hiding small and medium-sized cracks and preventing the appearance of new defects. The brand's collection is not as diverse as compared to its European competitors, but X-Glass products are affordable. In other words, this is an excellent option for low-budget repairs without compromising on the quality of the coating.





Reviews

According to independent consumer ratings, fiberglass from the Oscar brand occupies the leading position, with Wellton products slightly inferior to them. Many users note that the cost of the roll is above average, but the higher price is compensated by the impeccable quality of the material and the ease of its application.

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





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





It is better to refuse to buy cheap Chinese and domestic fiberglass. The material spreads under the influence of glue, requires considerable effort for fixation, and when further painting at the joints it sometimes clings to the roller and lags behind the wall.





Preparatory work

Gluing fiberglass - simple process which you can do yourself. Before starting work, make sure that your hands are protected with gloves and your respiratory organs are protected with a respirator. The fact is that fiberglass can form particles when cut. If they come into contact with the skin, they can cause a burn.

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







Before gluing the material, determine its front side. When you unroll the roll, it will be inside. External side(on which glue is applied) is more rough.

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





Usage

Fiberglass is used in many types of construction and finishing work:

• reinforcement of walls for a higher quality finish;
• preventing the formation of cracks in the finish coating and masking existing cracks;
• preparing walls for applying a decorative coating - when using fiberglass, you don’t have to putty the surfaces with finishing putty;
• leveling walls;





• creating original effects on the surface of the finishing coating (for example, marble effect);
• use in roofing work as a basis for bitumen mastic(apply special types materials that improve the adhesion of roofing and mastic);
• pipeline protection;
• waterproofing work - fiberglass is used to strengthen and protect polyethylene sheets;
• organization of drainage systems.







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

The use of “web” is recommended especially for those surfaces that are subject to constant mechanical stress. Wallpaper, paint and other materials fixed on top of fiberglass will last you longer without changing the original attractive appearance, even if the structure shrinks.





The glued “cobweb” fabric allows you to avoid many operations. You don’t have to prime the surfaces; you also don’t need finishing putty (if you don’t plan to glue wallpaper). If the walls are relatively smooth, without potholes, then it is enough to fix the fiberglass.





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

It is ideal for application under ceilings as it will provide a flawless finish. Fiberglass glued to the outer corners will help you quickly and beautifully paste wallpaper in this area.





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