The use of fiberglass spider web allows you to make the interior decoration both more durable and even. And various types of fiberglass, each of which has its own characteristics, make it easy to choose the right option for any conditions - from the ceiling of an apartment to the walls of an industrial building.
Using spiderweb fiberglass, you can increase the strength of the surface of ceilings and walls, reducing the likelihood of cracks without using expensive technologies and saving time. These features make the "spider web" one of the most popular finishing materials. Although for different conditions it is desirable to use both your own type of fiberglass and a suitable glue.
What is a "spider web"
Painting fiberglass is an environmentally friendly and lightweight material based on fiberglass and organic resin. It is a non-woven fabric that is very tear-resistant and does not have a clear pattern. The surface of the canvas consists of fibers, which, unlike fiberglass, do not intertwine and are arranged in a chaotic manner. And the material got its name due to its soft and pleasant to the touch texture.
Depending on the thickness, the "cobweb" is divided into classes. On the market, you can find options with a density of 25 to 65 gsm. m. The higher this indicator, the more durable the surface finished with fiberglass will be. However, for ceilings, on the contrary, it is recommended to choose a lighter version that adheres better to a horizontal surface.
Types and parameters
In construction, three main types of fiberglass cobweb are used - with a density of 25, 40 and 50 g / m 2. The first option, 1 m 2 of which weighs only 25 grams, is optimal for painting ceilings, since less weight increases the convenience of gluing. Because of this, the material is often referred to as "ceiling spider web". In addition, glass fiber with a low density absorbs less paint. However, it can be used only in the absence of large irregularities and surface cracks.
A "gossamer" with a density of 40 g / m 2 is considered universal, as it is almost twice as strong as lightweight material and cheaper than thicker options. This option is chosen for the subsequent painting of surfaces, the likelihood of damage to which is higher than that of the ceiling. The use of fiberglass is also allowed for the ceiling, finished with dilapidated plaster, and in rooms with high vibration load.
One of the most durable types of "cobweb" - material with a density of 50 g / m 2 - allows you to close cracks of considerable size. Withstanding a large mechanical load, it can be the only option for finishing the premises of a production hall, workshop or garage, in which the probability of damage to the enclosing structures is much higher. The cost of its installation increases - both due to the price of the "cobweb" and due to the fact that the high density also increases the consumption of glue for the fiberglass cobweb. Due to significant costs, this option is practically not used in residential buildings and apartments.
Benefits of fiberglass
To buy quality material, it is advisable to choose products from well-known brands - such as the Finnish company Wellton, the Dutch brand Spektrum and the Swedish manufacturers Samtex and Oscar. It is worth paying attention to domestic production - for example, to X Glass spider web, produced in various regions of Russia. Depending on the brand and density, their price can differ significantly - from $ 100 to $ 250 and more for a roll of 50 m 2.
Materials such as fiberglass Oscar spiderweb, which are durable and affordable, have proven themselves quite well. You can only cut or tear it on purpose, using sharp objects. For fiberglass of this brand, a minimum of paint is required - even if the painting work is carried out without putty. And it can be painted repeatedly, in contrast to the products of lesser-known brands.
The painting fiberglass cobweb Wellton is also in demand during repair and construction works, the advantages of which include:
- increased fire safety due to the incombustibility of the material;
- resistance to high temperatures, humidity and aggressive environments;
- long service life;
- high density.
Regardless of the brand of "cobweb", among its advantages are the following characteristics:
- environmental friendliness, which is expressed in the ability of the walls finished with fiberglass to "breathe", letting in water vapor and maintaining an optimal level of humidity;
- lack of static on the surface;
- easy cleaning - even stained glass fleece is easier to clean than other finishing materials.
An insignificant disadvantage of using the "cobweb" is the danger of being injured by small particles of material when cutting it. For this reason, it is best to work with fiberglass by wearing personal protective equipment - hand gloves, respirators, goggles, rubberized and tight clothing.
The most popular use for glass fiber painting is for walls that have already been plastered and finished with plasterboard. In this case, the material quite effectively replaces the finishing putty, preventing the appearance of new flaws and cracks, and hiding the old ones. At the same time, the use of fiberglass cobweb allows you to additionally reinforce the base - a wall or ceiling - if it is impossible to use drywall (for example, due to the fear of reducing the height of an already small room due to the drywall sheets and profiles holding them). You can also buy fiberglass instead of embossed wallpaper - the installation of the "cobweb" will take less time and money.
In the absence of serious requirements to the quality of the surface, the "cobweb" is not even necessary to putty. It is enough to properly glue the material using a special glue for fiberglass and paint. Although this consumes 2-3 times more paint.
Thanks to the use of fiberglass, the painting walls and ceilings are protected from cracking as a result of:
- shrinkage of the building;
- thermal expansion of enclosing structures;
- constant exposure to vibrations from nearby equipment, construction equipment or railways.
Fiberglass, which is glued only with a special cobweb glue, can also be used as an intermediate layer for polymer and vulcanized roofing materials. To ensure adhesion, the coating is protected by a sheet from one side. You can find fiberglass and in the composition of waterproofing materials, wall and floor panels, and even pipelines for which the "spider line" serves as additional protection.
Features of the "cobweb" sticker
There are several nuances that allow both to properly glue the fiberglass, and to do it with minimal consumption of materials. First of all, before performing work, you should definitely make sure that certain conditions are met - temperatures within 15-25 ° C and humidity not higher than 60%. During the gluing process, the fiberglass should not be exposed to a draft or direct sunlight. Approximately the same requirements are indicated in the instructions for Bostik glass fiber glue, which is one of the best options for performing work.
The process of sticking the "cobweb" begins with the preparation of the surface, which must be free from dust and completely putty, except for the smallest cracks. At the same stage, it is chosen which glue for the fiberglass will be used. First of all, one should abandon the usual solutions and mixtures with which wallpaper is glued - substances based on starch do not hold such a canvas well. A more suitable option may be to use Bostick glue for fiberglass, which contains PVA with a strength several times higher than that of a starch base.
It is not recommended to choose plaster as a base - due to its high density, it cannot be saturated with glue and it will not be enough to hold the canvas firmly. Liquid putty is also not suitable, and after trying to stick a "cobweb" on it, bubbles may appear in places that are not sufficiently saturated with adhesive. All this can be avoided only by using glass fiber glue - ready-made or in the form of a mixture.
It is advisable to use your own adhesives for each type of "cobweb":
- Oscar fiberglass glue will be the best option for gluing material of the same brand with a density of 40 g / sq. m;
- a similar adhesive is best suited for Wellton fiberglass;
- the Cleo glue for glass fiber, which is also used for non-woven wallpaper, is compatible with any brand of canvas.
You can achieve the optimal consumption of the mixture, counting that 10 grams is enough for 1 sq. m of fiberglass. And one 300-gram pack is enough for a 25-meter roll. The preparation time of the solution, if it is purchased not ready-made, but dry, does not exceed 10-15 minutes. And setting takes place within 12–48 hours, depending on the brand of glue and fiberglass - you can specify the specific value on the package with the mixture.
The technique of how to glue the fiberglass consists of several stages:
- Surface putty.
- Wall or ceiling treatment with a deep impregnation primer.
- Application of pre-prepared glue. Using this method, how to glue fiberglass to the ceiling or walls, it is important not to miss a single non-impregnated area. At the same time, do not leave any excess adhesive, which can be removed with a spatula.
- Bonding the first sheet, starting from the corner, and smoothing the edges of the material to improve the reinforcing properties.
- Applying the next portion of glue with an approach to the already glued part (the canvases are glued with an overlap).
- Laying the next piece of fiberglass.
- Cutting canvases with a clerical knife clearly at the junction and removing the cut parts.
- Repeating the same actions until the surface is finished.
Regardless of whether the walls or ceilings will be pasted over with wallpaper or painted, after the fiberglass has completely dried, they are treated with a finishing putty. And the already putty surface is cleaned with an abrasive mesh (N150 or N120). It is not recommended to skip this stage, since it will be possible to glue the fiberglass for painting without additional leveling only with a large overspending of paint.
After the end of the work, the remnants of Oscar glue for fiberglass or other mixture, as well as the "cobweb" remaining after the work, should be disposed of along with the rest of the construction waste.
Let's sum up
Correctly glued "spider web" creates in the room the appearance of completely flat walls and ceilings. Therefore, it is often used as a base for decorative plasters, on which defects are especially noticeable. Thus, fiberglass solves some of the problems that arise during finishing work, and increases the service life of the ceiling or wall decoration. And the owner of the premises saves on this repair, and increases the time until the next one.
