Cobweb fiberglass - scope, principles of work. Fiberglass for putty - purpose and installation rules Features of working with fiberglass and the necessary auxiliary materials

Pouring into interiors, new trends dictate their own rules. And they apply not only to appearance the surrounding space, but also on its high-quality finish. Currently, special importance in the design of premises, in particular residential ones, is given to ideally flat basic surfaces, such as walls, ceiling, corners. Several methods are used to achieve such effects. One of the most common is fiberglass. Application of this kind building material allows you to create a flat surface, while simultaneously acting as a reinforcing coating. It is intended for interior decoration and can be used even in newly built buildings that have not yet shrunk. This is what influences the formation of numerous cracks, and the installation of fiberglass on the surface will almost completely eliminate their occurrence.

Fiberglass - what is this material?

Fiberglass - modern finishing material, which forms a completely environmentally friendly coating. Thanks to this quality, it can be used in rooms for any purpose: bedrooms, kitchens, children's rooms. It consists of fiberglass threads and organic resins. Fiberglass painting is made by gluing fibers in a chaotic manner. The canvas turns out to be quite dense without a special pattern, pleasant to the touch. Thanks to such plexuses, this material is simply called a cobweb.

By thickness, glass fiber is subdivided into classes, each of which corresponds to a certain density, which varies from 20 to 65 g / m 2. Depending on the selected indicator, the weight of the canvas, the resistance to mechanical stress, the strength of the coating and its reliability change.

Many people are mistaken when they think, comparing fiberglass and fiberglass, that this is exactly the same material. This is not true. The spider web is putty and high-quality painted many times, while it is an excellent reinforcing material.

Advantages of fiberglass

The advantages of this finishing material are quite weighty:

disadvantages

As a rule, any type of finish has drawbacks. Fiberglass is no exception. What kind of material is this that would not have some drawbacks? However, it is very important to correctly weigh the benefits versus the benefits. The main disadvantage of the canvas is small particles that can cause a very serious wound. In order to avoid this, it is necessary to cut only with gloves. When working with fiberglass, it is very important to protect both eyesight and wear special clothing. Such safety measures are necessary so that small particles do not get on the skin, as they can cause unpleasant itching.

Fiberglass: application and surface cladding

Any surface, be it a ceiling or a wall, needs a finishing, and gluing a fiberglass can simplify this process, completely replacing the need to use a starter putty. Especially in need of such a surface finish, often subject to mechanical damage and cracking. This strength of this material is due to the specific reinforcing properties. Fiberglass is most suitable for the ceiling. It can be glued to any surface: concrete, drywall, plaster and others. Moreover, its appearance will be perfectly smooth and even. Fiberglass is also used for painting; for these purposes, any paint and varnish material... However, in order to correctly carry out these works, it is necessary to become familiar with a certain technology. It is as follows:

Gluing fiberglass.
Surface treatment with a primer.
Putty application.
Surface painting.

It is very important to choose the right adhesive and primer. The strength of the structure will depend on this. It is also important to maintain the required time interval between pasting and painting.

Adhesive properties

When choosing glue for fiberglass, you need to take into account its appearance. This moment is very important, since the strength of fixation and the durability of the cladding completely depend on it. Typically, there are many brands of glue such as Wellton, Pufas, Bostik. Such compositions are made according to a special formula, contain only high-quality components that are completely safe for humans. They also form a film that prevents the formation of mold and mildew.

Scope of fiberglass application

Used to create a waterproofing layer. Cobweb fiberglass is often used for processing polymer canvases.
Roofing. Some types serve as the basis for bituminous mastics.
Drainage systems.
Pipeline protection.
They are part of high quality finishing materials such as Wall panels, floor coverings and etc.
Reinforcement of walls. Fiberglass painting forms reliable protection from cracking, even from those that appear due to the shrinkage of the house.
Cost savings. Due to the strength of this material, the period between repairs in the room can be significantly increased.

Glass cloth gluing technology

There is a certain technology on how to glue the fiberglass. Step-by-step description:

Surface treatment with a starting putty to smooth rough differences.
Grouting of obvious defects and covering with a deep-penetrating primer.
Applying glue to the surface, the optimal layer thickness is 1 mm. To do this, you can use a spatula, brush or roller.
It is necessary to start gluing the fiberglass from the corner of the ceiling or walls. The joints are additionally smoothed for better adhesion.
Subsequent canvases are applied with a slight overlap. This place is well pressed along the entire length and after that a cut is made immediately.
The cut parts must be removed immediately, and the ends of the blade must be pressed tightly to the surface.
After pasting the last strip, it is necessary to prime them. Dilute the glass fiber glue liquid enough so that it soaks the entire surface well.
Withstand a certain time until completely dry.
Fill with finishing mortar and sand to perfect smoothness.
Prime the entire surface.
Proceed directly to decorating.

When gluing the fiberglass and until it dries completely in the room, it is necessary to maintain the same temperature and exclude drafts.

How to paint the fiberglass?

Glued fiberglass on the ceiling or walls serves as a starting surface. It can be veneered different ways however, the most common is staining. This process, in contrast to gluing, is quite complicated and time-consuming both physically and psychologically.

The first difficulty lies in the specific structure of the canvas. Since fiberglass is produced by pressing fibers under high pressure, there is some distance between the threads. Therefore, the paint will be uneven and may need to be applied. a large number layers. And this, in turn, significantly increases paint consumption and, accordingly, financial costs.

The second nuance is glass shavings. It is she who can cause a lot of problems. During staining, these particles crumble, and if the body is not protected by clothing, then they will cause unpleasant itching when touched. It is worth noting that getting rid of it is quite difficult. It is better to immediately protect yourself by putting on a specially designed uniform at the beginning of work.

Weighing all the difficulties associated with staining, many are asking a well-deserved question: “Why use fiberglass? What will it give, what are the advantages? " However, the answer is unequivocal. Surfaces with such a finish are quite durable and reliable, their service life is significantly increased in comparison with other types, which will save on frequent repairs.

Summarizing

Fiberglass spider web is an irreplaceable thing during finishing works in premises for various purposes. Its significance is quite large:

The canvases qualitatively strengthen the surfaces of walls and ceilings from cracking, even in buildings that shrink.
Leveling is possible without additional work associated with plastering and puttying. And they, it is worth noting, are quite laborious, take a long period of time and, which is important, form a lot of dirt and dust.
Fiberglass can act as an independent textured coating or be a solid foundation for applying finishing materials.

Painting fiberglass, or as it is also called "cobweb", consists of fiberglass threads. In the production of spider webs, the fiberglass is pressed in a manner similar to the process of making ordinary paper. The result is thin and perfectly smooth sheets with a density of 25-50 g / m2. The standard width of the rolls of painting glass sheets is 1 meter. Usually, all rolls of glass canvas painting have a guaranteed length of more than 50 meters. Less commonly, rolls with special winding are produced, for example, painting glass canvas Wellton economy W40-30m, the rolls of which are 30 meters long. After winding, the rolls are supplied with protective end caps ("crowns"), preventing damage to the edges of the webs, with a product label and packed in a transparent shrink film. The product label of Wellton and Oscar glass fabrics contains a number of important information:

special for quick viewing of goods in the interior;
toll-free consumer support phone number 8-800-200-07-03;
information about;
voluntary marking sign, proving the fire safety of the goods;
properties of the product and its characteristics;
(placed on the back of a rectangular product label).

Despite the similarity of the manufacturing process, glass fibers are very different from their paper counterparts:

are not afraid of water, chemicals and mechanical damage;
do not support combustion and do not spread flame over the surface;
do not accumulate static electricity and do not attract dust;
reliably reinforce walls.

But they also have qualities that resemble the properties of paper:

cobweb canvases consist only of natural ingredients;
allow air and steam to pass through;
prevent the formation of fungus and mold on the walls;
do not cause allergies.

Fiberglass does not have a pronounced relief, therefore, you can repaint the fiberglass as much as you like - since there is no relief, there is nothing to fear that it will be lost. The canvases of all fiberglass canvases can vary in color from white to a light yellowish tone. Differences in color are due to the specifics of production and do not affect the quality of the material. Fiberglass cloths of the same article, having differences in color, when glued to the surface, fit together equally well, so there is no need to select rolls of the same color for work.

Why do we need glass canvas painting?

The fact is that the walls in new buildings shrink for several years, and because of this, cracks appear on them. Conventional paper wallpaper as a result, they will simply tear, the plaster will crumble. And the "cobweb" will not only withstand all these loads and hide the existing cracks and irregularities, but will also prevent the cracks from growing and protect the walls from the appearance of new ones.

You can glue the "cobweb" on any carefully primed surface, be it concrete, drywall, chipboard, plastic, etc.

In addition to protecting the surface, glass fiber painting is often used as a finishing material for painting. With the help of a painting glass cloth, you can get a decorative surface with a special texture, formed by randomly located finest glass fibers.

It is important to know that on the market you can find a fake glass canvas painting. This is bituminous, or roofing fiberglass, which cannot be used in interior decoration premises. The main difference between real painting glass fiber and bitumen is the diameter of the glass fibers that make up the material. Painting fiberglass consists of fibers with a thickness of only 8-12 microns, while bitumen fiberglass contains coarser and thicker fibers - more than 13 microns. By the type of fiber, glass fiber painting is classified as "A", while bitumen glass fiber is class "B".

To get the perfect repair result, you should refrain from buying bituminous glass fiber.

Well, now everything is ready - you can start painting, or decorate the walls at your discretion!

Want even and smooth walls, which in a few years will not be covered with a network of cracks? This can be achieved by paying a considerable amount. professional craftsmen... And you can stick a cobweb under a layer of paint, or, as professionals call it, a painting glass canvas.

According to the structure, the fiberglass is a non-woven fabric made of fiberglass threads, which are pressed, like paper, onto special equipment... They look the same - smooth and thin, but, unlike paper, they are not afraid of water, do not burn in fire, do not accumulate dust, and are resistant to most chemicals. Density from 25 g / sq. (like office paper) up to 50 g / sq.

Material without flaws

Fiberglass is an absolutely environmentally friendly and hypoallergenic material. It contains only natural substances: quartz sand, lime, soda and dolomite. The surface of the canvas allows steam and air to pass through, unlike vinyl, and will not start under it. Additional benefits:

reinforces walls and ceilings, prevents cracking,
withstands most household mechanical damage (furniture, hands and toys),
self-tapping screws and other fasteners are well held in it,
does not burn (withstand temperatures up to 1300 degrees) and does not emit toxic substances,
it can be washed, including with detergents household chemicals brushing.

Unlike fiberglass, fiberglass has no relief, its surface is smooth and extremely suitable for painting. After being pasted and painted, it looks like a perfectly aligned and plastered wall, but the cost of creating such a covering is much lower. This material can be glued both to concrete and to drywall, brick, even to partitions made of sandwich panels.

Fiberglass is an excellent choice for new builds that will shrink for several years. They can paste over not only walls, but also the ceiling, and door and window slopes.

What is required

In order to glue the fiberglass on the walls or ceiling, you need a minimum of materials.

Special glue is needed - Glufix 99, Wellton, Holtex or Oskar, the latter is more common.
Primer, for example the same Oskar, on a latex basis. You can also use slightly diluted glue (2 parts water to 1 part glue).
Short nap roller for applying glue and shallow paint tray; flat, narrow brush for working in corners.
Sturdy utility knife and plastic spatula for trimming edges.
Water-based latex paint that allows walls to "breathe".

Also, you can't do without a partner. One person should glue the panel at the top, and the other should align and glue it at the bottom.

When choosing fiberglass in a store, you need to take a closer look at its edge: it should be smooth and not frayed.

Preparation: as easy as shelling pears

If there was already a decorative coating on the wall before, it must be removed: wallpaper, and falling off plaster, and layers oil paint... An exception can be made for sturdy plaster with minor damage - chips, cracks and traces of furniture.

Before sticking, it is still better to level the wall and putty large cracks and chips, you may not be as careful as before painting or plastering. Slight irregularities and depressions are allowed. The wall or ceiling is swept with a stiff dust brush, if there are greasy spots, remove them with a solvent. Then or with diluted glue.

Fiberglass is sold in rolls, the standard width of which is 100 cm, but the length can vary - 10, 20 and 50 m. It must first be cut into panels of the required length, adding a few centimeters in reserve. It is better to cut a piece later than to find out that literally a few millimeters were missing.

Gluing fiberglass on walls

Fiberglass is glued, like non-woven and glass fiber wallpaper. It is not the panel that is smeared with glue, but the wall itself, the area is a couple of centimeters wider than the wallpaper. The cut panels are glued end-to-end, starting from the upper corner and making sure that they go strictly vertically. The seam and the canvas itself are additionally smoothed and pressed with a spatula, the excess from below is cut off with a clerical knife.

If the edges of the roll are nevertheless damaged during storage, or you need to paste over a small area of a complex shape, then adjacent pieces can be glued with an overlap, so that the tousled areas completely overlap. In this case, the joint is not sealed, but is immediately cut in the middle with a clerical knife. The top strip with the edge is removed, gently lifting the edge of the panel, the piece is removed from the bottom. It is important to make an even cut to the base, then the seam will be invisible. The seam is smoothed with a spatula, if necessary, you can add a little glue under the panels, removing its remnants with a paper napkin.

The glued fiberglass is treated with a primer or, again, with highly diluted glue and left for 12 or more hours to dry. This treatment will significantly reduce the amount of paint that will be required for further dyeing. Fiberglass is not as sensitive to temperature changes and drafts as wallpaper, but it is better to leave the windows closed. When it is completely dry and adheres well to the wall surface, you can start painting. This coating can be repainted many times, it will not deform or deteriorate from this.

Preparing surfaces for painting is a complex business that requires high qualifications. But even this does not always save from the appearance of small cracks - the house sits down, the plaster dries unevenly. As a result, we have small gaps that spoil the appearance. Painting fiberglass is a material that makes it easier to prepare surfaces for painting, and also serves as protection against small cracks.

Painting fiberglass - what is it and why

When the building shrinks or the plaster / putty dries up, small cracks form on the walls and ceiling. They spoil the appearance of painted surfaces very much. To prevent their formation when plastering, use a paint net. It reinforces the finishing materials preventing the formation of large cracks. Microcracks are fought with a glass fiber painting. It is a thin non-woven fabric made from many glass fibers of varying thickness. The fibers are interconnected chaotically, which prevents the appearance of cracks. There may be microcracks, but they are not visible. This determines the field of application of the glass-fiber painting - to improve the quality finishing walls and ceiling.

To keep the painted surfaces even and smooth, use a "gossamer"

The thickness of this material is small - it is translucent. Due to its appearance, it was named "spider web". It is sold in rolls 1 meter wide, has a different density - from 20 g / m2 to 55 g / m2. The density is selected depending on the area of application. For interior work, 30-40 g / m 2 are more often used.

Fiberglass is glued with glass fiber glue on more or less even walls. It successfully masks small cracks (up to 0.5 mm wide) and irregularities, creating an even surface. Therefore, this technology is becoming more widespread - it simplifies the preparation of walls for painting (putty), and the result is no worse. The same material can be glued to drywall. It successfully masks the joints and prevents the formation of cracks in these places. The main thing when gluing the seams of the fiberglass should be located away from the joints of the gypsum board.

Painting fiberglass is inconvenient to work - fiberglass is pricked, its smallest particles can get into the lungs. Therefore, it is necessary to work in protective clothing and, preferably, in a respirator. After it is glued on and hidden by several layers of finishing materials, there is no talk of any migration of fiberglass. In this state, it is absolutely harmless.

Application methods

Glue the painting glass canvas on a flat gypsum plaster or on a layer of starting putty. According to the technology, after gluing, leveling is required with a thin layer of finishing putty (on a sdir), after - a primer, and then painting. With such a sequence of works, paint consumption is minimal; for a good result, 2 layers of paint are enough. Despite the additional cost of filler, if you are using expensive paint, it is best to stick with this technique. Also this method is used if the paint is glossy or semi-glossy.

There is another approach. The cobweb is glued, after drying it is painted. No puttying. In the end, a good result is obtained - a slightly structured surface with a slight "furry". But the paint leaves a lot, and layers for a normal result have to be applied at least 4. The first pass the paint is absorbed very quickly, the consumption is 3-4 times more than the norm. At the same time, the appearance of the wall is unsatisfactory: in some places there is little paint, in places where they have passed the roller several times in one place - there is a lot of it.

The second layer of paint takes almost half as much, the view is slightly better. The consumption is reduced further, but not at the same pace. After 4 coats, the appearance against the wall is already normal, but the total amount of the coloring composition is impressive.

To reduce paint consumption, after gluing, coat the glass fiber painting with a primer. It can be in two layers. It will take a lot of primer, but much less paint. Moreover, even the first layer will fall well. For a good result, you will need 2-3 layers, but with a normal consumption. So this method is also not bad, but it can be used with matte or semi-matte paint.

Bonding technology

Painting fiberglass is glued to glass wallpaper glue. Good glue is important, but it doesn't have to be expensive. The gluing technology is very similar to wallpapering:

As you can see, nothing complicated. Only all operations must be carried out carefully, achieving better result that you are capable of.

There are several nuances in terms of working conditions. The room should be free of drafts, the temperature should not be lower than + 15 ° C, the humidity should be within normal limits. Doors and windows are kept closed until the glue dries. If the sun is hot, it is better to curtain the windows. That's all, actually.

The cobweb fiberglass has proven itself as a finishing material and helped to get rid of many problems. Today, even in new apartment there are many problems with the repair. Cracks appear on the walls or ceiling, which are very difficult to get rid of. Even if they are plastered repeatedly, they will reappear. The cobweb mesh is designed to change the situation. The popularity of this material is growing more and more. Its use avoids possible problems further. And it is very simple to glue it. The main thing is to do everything right.

Fiberglass, one of the types of materials for putty or painting. It is a thin non-woven sheet that is pressed from fiberglass strands. It looks like a grid. This material is manufactured roll method, one meter wide and twenty and fifty meters long. It should be borne in mind that this material is not intended for fine finishing. Its area of application is to protect surfaces from cracks.

The spider web has a density from 20 g / m2 to 60 g / m2. For painting, a mesh of lower density is used, for reinforcement of a 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 ecological situation of the room. When using it, the appearance of fungus is prevented, it does not react with chemicals. Can be used on objects with high humidity.

Fiberglass spider web 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 gluing wallpaper. But this can lead to the formation of bubbles, which appear due to the fact that the drying process takes a very long time.

You should know! The fiberglass has two sides - the seamy side and the front side. They differ in their structure, the front side is very smooth to the touch. The wrong side with villi, it sticks better. Although there is a correct division into parties, 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.

Glue mixture

The glue for the "spider web" should be selected correctly. It needs a special one, which is designed specifically for this purpose. There is no need to try to save money and use other types of glue. This can lead to consequences that could not have been expected.

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

the glue is completely environmentally friendly;
leaves no stains or marks;
final setting time - 2 days;
does not react to cold.

Cobweb mesh application rules

To glue the cobweb, special skills are completely unnecessary. 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 take on large volumes of work right away. 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 being prepared. It is advisable to remove all irregularities, they can cause the appearance of bubbles. All dirt is washed off with a damp cloth.
The adhesive is applied to the wall or ceiling. You shouldn't feel sorry for the glue, but you don't need to use it a lot either. The fact is that the process of applying the mesh is very similar to wallpapering. The same rules apply here.
A pre-prepared mesh of a cobweb of the required width is applied to the surface. It is best to keep the front and back sides correct.
The fiberglass is well smoothed. If you can't do it with your hands, you can use a soft cloth. The remaining air is expelled with a spatula. You should move from the middle to the edge. But it's important to be careful. The cobweb can be easily torn and should be avoided.
Anything that sticks out is clipped. The glue is applied again. A well-impregnated leaf turns dark.
The subsequent sheets should be properly overlapped. Drafts must be avoided. Otherwise, all the work will go to waste.

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

Fiberglass and drywall

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

Unlike simple walls or ceilings, when the cobweb is glued with an overlap, you need to glue it back to back on drywall. Pruning should also be avoided. If this is not observed, then cracks may form in these places.

Final stage

When it is completely dry, and this can take up to two days, you can start filling the surface. If painting is supposed, then it is better to use a fine filler. It should be applied in several layers. Each of the layers must be allowed to dry completely. After that, you can start sanding using a sandpaper. We must not forget that, as with simple painting, the walls or ceiling must be primed first.

Now more and more often they skip the stage with filling. This is replaced by applying a generous layer of glue. With the help of this trick, it will be possible to reduce paint consumption. It should only be borne in mind that in this case, the mesh structure of the cobweb will be noticeable. It will be impossible to change this 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, respirators.

But such minor shortcomings cannot negate the advantages that the spider web has. Its use allows you to avoid many unpleasant moments in the future. In addition, pasting it does not require special skills.
