Sometimes it can be difficult to paint. Sometimes it's pretty difficult task, the implementation of which requires a certain level of qualification of the master. However, even the skill of workers is not always able to save the finished surface from the formation of various. The fact is that the new structure begins to shrink and does not dry very evenly.
Quite noticeable breaks may appear on the surface, which can ruin appearance. Special material, painting fiberglass , greatly facilitates painting work. It simplifies the preparation of any surfaces for subsequent painting, and also prevents the appearance of small defects and defects.
Result painting works this significantly deteriorates, since the appearance of the surfaces inevitably deteriorates. It is to prevent their formation that a special painting non-woven fabric. With the help of this material, the finishing surface itself is strengthened, that is, reinforced.
What is this miracle fabric? It is a non-woven, rather thin material. It consists of many glass fibers, differing in their thickness. Their chaotic connection with each other ensures the impossibility of the formation of noticeable cracks.
Microscopic defects are, of course, possible, but they are not noticeable.
This ability determines the scope of use of fiberglass: a noticeable improvement various types final finishing of the ceiling and walls.
Fiberglass painting web
Its technology is as follows:
All procedures are quite simple, but the main thing when performing them is thoroughness and accuracy. Then you will get the desired result.
When performing all work, certain conditions must be met:
- the room should be completely free of drafts;
- temperature readings must be at least 15 degrees;
- The humidity in the room should also be within normal limits;
- and it is better to keep the doors closed until completely dry;
- from bright sun rays It is advisable to curtain the windows.
Painting fiberglass: features and advantages
The material is made from organic resins and mineral fiberglass, and is considered environmentally friendly. Its continuous fabric has impressive tensile strength.
Its constituent fibers are not intertwined, like similar ones, but are glued together in a rather chaotic order. The material has a fairly affordable price, and has received the common name glass interlining.
People simply call it “ cobweb", which it somewhat resembles with its soft structure. By type, the material is divided into various classes, differing in density and thickness.
These indicators affect its cost: the larger they are, the higher it is. Lighter and thinner items are recommended for ceilings. More dense types are able to withstand significant loads without damage.
The material has the following performance characteristics:
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 of modern materials, painting fiberglass web provides previously unavailable advantages in the process of finishing work.
Area of application of the material
What is it? Fiberglass is non-woven fabric, obtained by pressing and consisting of tiny 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 cobwebs for reinforcing walls and ceilings.
Specifications
Painting fiberglass is a lightweight fibrous material obtained from natural raw materials, which is 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 release into the air harmful substances 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.
Precautions
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 when certain temperature(from + 15 to + 25 °C) and air humidity 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 side and a smoother front side: it is important not to confuse it.
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 a dry substance - the preparation time should not exceed 15 minutes (a ready-made solution is 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 also whether it is 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 plaster 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 glued several days ago, it needs to be cleaned of dust;
- the adjacent surface is protected with masking tape;
- the putty is applied in two layers at intervals 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 with sandpaper grain size 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. And yet painted walls or the ceiling will have a more attractive appearance if it has been previously puttied; in this case, you need to apply a primer. To paint walls, it is better to choose paints based on water based, which fit well and are easy to use.
Painting of fiberglass is done using the same technology as dyeing 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 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 cosmetic repairs won't take much longer.
Painting fiberglass, or as it is also called, gossamer, is an excellent material for interior decoration. It is both useful from a technical point of view and a very attractive thing for creating interiors. If you work with it correctly, then surfaces that may crack over time after finishing will no longer have such properties. The use of fiberglass practically eliminates the possibility after completing the entire complex of finishing works. But there are two myths about fiberglass that are actively supported by the manufacturer. In this article we will tell you what painting fiberglass is and how to work with it.
By the way, if you pick up the advertising brochures with descriptions enclosed in a roll of this material, these myths will immediately attract your attention. They will literally catch your eye! The first thing you will see is “ Easy to glue" Second - " Easy to paint».
How to glue fiberglass
Regarding the first, by and large this is true. But experienced painters who know what painting fiberglass is and how to work with it can only smile about this. They are well aware of all the pitfalls of working with the “cobweb”. Gluing is easy in the sense that the glue is applied directly to the wall or ceiling, and then this miracle material is rolled out from a roll over the smeared surface. But if the surface absorbs too much, you will suffer!
The wall needs to be primed with a deep-penetrating primer, and preferably repeatedly. And apply the glue so that there is a strong layer, as if butter was applied to the bread in slices. It will work, but there is one more thing!
How to paint fiberglass
Fiberglass consists of tiny fibers, which are actually the smallest elements of glass. When these small villi begin to rise into the air, you will feel an unimaginable itching all over your body. And if the ceiling is pasted over, then all this mass will literally spill out onto your head! There was no scabies nearby! And painting this surface is also extremely difficult. Fiberglass interesting material, how to work with it?
Think for yourself, is it easy to paint glass? It's not exactly glass, of course, but something like that. It's hard to put the problem of painting into words. But when you start painting, you will understand that by writing “easy to paint” on the glass wallpaper label they were just making fun of you! Some people prime the finished surface several times. But this partially solves the problem.
Since there are a lot of pores in the surface of the material under discussion, it is extremely difficult to paint over them! After the next layer, the pores into which the paint has not flowed are again visible, and this, literally, makes the appearance of the surface extremely unsightly. In this regard, others came up with the idea of applying another layer of putty on top of the fiberglass, cleaning it and then painting it.
Someone might have a question: “Why then did they actually glue the fiberglass? Isn’t it easier to putty the wall and paint it right away, bypassing the “prickly” work?” Remember that the surface covered with fiberglass will not subsequently crack. That's why it sticks.
No wonder they say: “The need for invention is cunning.” Having suffered a fair amount with fiberglass, some enterprising painters have come up with a lot of ways to avoid difficulties when working with it. For example, . The goal is to avoid cracks after the entire work package has been completed. But where are these cracks possible? Only at the joints of gypsum sheets. Why then cover the entire surface? It is much easier to cut narrow strips of fiberglass and glue them directly to the joints of the sheets.
Someone might think: “What about the appearance? The ribbons will be visible.” They are immediately visible.
How to make painting fiberglass webs easier
What if after gluing? Then everything will level out. And then you can paint it. Moreover, it is much easier to paint a putty surface than fiberglass. This process includes several stages. First, the seams between the sheets are aligned gypsum mixture. After it dries, the “cobweb” is glued on. After letting it dry, you need to apply a layer of primer. After it dries, apply a layer of putty along the stripes to hide them. After this layer has dried, we putty the entire surface.
Sanding with sandpaper or silicon mesh, final priming and finally painting. Not an easy matter. To simplify this process, some painters have gone even further. After the seams are already filled with gypsum mixture, they apply a layer of finishing putty to them, and fiberglass is glued onto this fresh strip. They immediately putty on the surface to visually hide the edges of the canvas strips. And after drying, you can already putty the entire surface. The final stage is the same.
By the way, the same principles apply if you are leveling concrete slabs ceilings It is enough to process the seams between them in the same way.
If you think that all this is quite complicated, then try to do it as the manufacturer advises. After a short time after starting work, you will have a desire to start changing something. Perhaps then you will master this method. And then, after everything is over, you will be able to learn one important thing: the effect is the same, and there are much fewer troubles.
Painting fiberglass web - a popular option repair and finishing materials made of fiberglass. Can you remember another similar material, the so-called fiberglass wallpaper- but it’s already ready finishing coat and it's suitable for smooth walls. And if the walls need to be leveled and cracks removed, then fiberglass web can handle this better and faster than plaster. This is a thin (25–50 g/sq. m), opaque and pliable canvas, which, thanks to its texture, perfectly strengthens and levels the walls before painting.
How are fiberglass webs made?
Despite the name, fiberglass web is not woven. Fiberglass canvases consist of glass fibers, which, according to technology, are distributed and interconnected by pressing using an organic resin additive. The fabric undergoes crystallization and is easy to roll. In this form, packaged in shrink film, the cobweb is delivered to the consumer.
Why do you need fiberglass web?
Fiberglass web as a new generation material satisfies modern requirements for wall repairs. In addition to good plastering properties, fiberglass sheeting creates a reinforced, non-destructive layer on which you can paint or wallpaper. And this, unlike a number of plastering and painting works, is done quickly - by gluing it to the wall.
The finished result is a smooth surface: textureless, rough, resistant to moisture and mechanical damage, environmentally friendly, breathable and fireproof. And, most importantly, durable - it can be repainted again and again if desired.
Where can it be used?
Manufacturers recommend fiberglass web fabric for already plastered walls and ceilings, or lined with plasterboard. Fiberglass can be successfully replaced finishing putty. Especially on surfaces prone to cracking, the web will prevent cracking and the formation of damage and flaws - that is, all those imperfections that we usually see on walls prepared without fiberglass layers.
The use of cobwebs is relevant when walls need additional reinforcement and strength without increasing the load. And also if it is necessary to hide the joints between slabs, in particular, plasterboard (which, when stored in a warehouse, absorb excess moisture and become deformed when drying).
It is advisable to use cobwebs in new buildings: it prevents defects in walls and ceilings that form after shrinkage, greatly simplifies the maintenance of surfaces and guarantees their long-term use.
Due to its properties, fiberglass is excellent in rooms with high humidity: kitchens, bathrooms, plumbing rooms.
The material can also be used for roofing works, strengthening walls, protecting pipelines, waterproofing and design purposes.
Why do they prefer fiberglass: the advantages
It is worth buying fiberglass from a specific manufacturer if the description of the material contains the advantages described below. For example, fiberglass web "Vitrulan" made in Germany is environmentally friendly and recommended for use in children's and health care institutions. It can be guaranteed to be used for painting - unlike other brands, Vitrulan does not act as a rough surface beyond the paint layer.
The practice of using fiberglass web shows that it has:
- Resistant to moisture accumulation - this is evidenced by water-repellent properties.
- Resistant to damage - the surface cannot be scratched or punctured.
- Fire safety - fiberglass materials do not ignite.
- Reinforcing ability - the fibers of the fabric, after gluing it to the surface, do not stretch and create a monolithic layer.
- Environmentally friendly - fiberglass web consists of substances that are involved in the production of glass, therefore it does not contain harmful compounds, is not an allergen, does not enter into chemical reactions with the environment.
- Air-vapor permeability - the canvas “breathes”, that is, it allows air and steam to pass through, preventing the development of mold and mildew, and waterlogging of the premises.
Fiberglass is convenient to transport and work with: the web is sold in rolls of a meter wide and optimal (20 and 50) lengths.
Price for cobweb for repairing walls for painting
Prices for cobwebs per roll 1m x 50m, i.e. for 50 squares from 278 rubles. per roll.
At its low price, fiberglass web creates all the conditions for savings: there is no need for an expensive amount of rough finishing and plastering works. The cost depends on the density of the canvas and its length in the roll.
In any case, this is - ideal option for developers and customers repair work who want to get effective results quickly.
Choosing glue for web
Traditional PVA glue is not suitable for gluing fiberglass materials - marks may appear on the surface of the coating. yellow spots. You need to use special glue recommended by the manufacturer. For example, Virtulan offers customers its special adhesives and other related products.
You need to buy glue with a reserve, counting on higher consumption compared to regular wallpaper. Dilute according to the instructions, taking into account the proportions - not thicker or thinner than recommended, and then there will be no unexpected surprises.
How to use the web: conditions
When gluing, you need to follow the same measures as for any wallpaper. Desirable:
- prevent drafts during work and until the walls dry;
- ensure dryness in the room;
- avoid direct sunlight on the canvas;
- maintain a constant air temperature.
Preparatory work
Surfaces (walls, ceilings) are prepared in the same way as for wallpaper, but leaving small cracks- they will be reliably covered with fiberglass and will not allow them to expand. But if the cracks are deep and it is possible to apply putty with a spatula, then it is better to do this. After drying, sand with abrasive sandpaper.
Thus, a spider web under fiberglass is required relatively flat surface, ideally treated with a deep penetration primer.
Cutting and gluing the first canvas
When unfolding rolls, you should pay attention to the manufacturer’s instructions on where the front part is located. It makes a difference even though both parts look the same.
The edge will have to be cut off a little with scissors if the edges of the fabric are curled or damaged.
Apply glue liberally to the prepared surface with a roller or spatula (the width of the roll). When in contact with the canvas, the glue will quickly absorb and there will be no excess that will need to be removed. The glue dries for about 15 minutes, this is enough time to adjust the first canvas.
You can cut the canvas to any length, the main thing is that it is convenient. But if for walls the length can be solid, to the entire height (plus 5 cm), then for the ceiling it is necessary to cut off pieces of one and a half meters. Otherwise, it will be inconvenient to work, and the canvas will not stick well.
You need to work from the corner of the room. Applying it to the coated surface, smooth it with your hands, aligning it with the corner, and spread the glue under the canvas with a spatula, removing air bubbles. The standard technique is from the middle to the edge, as is done with regular wallpaper. It is better to glue sheets on the ceiling along the room from the door to the window.
So, the sheet has stuck securely to the surface. It is necessary to cut off excess centimeters, if they have “formed”, and coat the top with glue again for better impregnation, spreading it with a spatula. If the canvas darkens evenly from the moisture of the glue, it means that it is well saturated.
Shutdown
The next canvas is glued overlapping - and the glue must be applied, accordingly, while gripping the edge of the previous canvas. You need to work with the next sheet in the same way as with the first: stick it, soak it, press it.
It is important to ensure that the butt seam is invisible. To do this with a blade sharp knife you need to draw a line - cut through both layers from top to bottom. Once again saturate the seam with glue. The seam cutting line may be uneven, but after finishing it becomes noticeable.
It is better to cut the canvas in the corners and apply patches.
Fiberglass may not hold the gap if the joining of the panels takes place next to assembly seam between sheets of drywall, and even more so along it. It is better if the seams of the wall and fiberglass are located a couple of centimeters from each other.
Safety precautions when working with canvas
Observance of basic safety precautions is required: when working, use gloves, tuck in the sleeves of clothing, wear a hat and a respirator. This precaution protects against the penetration of tiny sharp fibers of material onto the skin and into the respiratory tract.
Further processing can be carried out after the glue has dried - usually within a day. Before painting, the surface is puttied. In one or two layers - it’s up to the master, it depends on whether you need to hide the texture and reduce the amount of paint.
In practice, puttying is often skipped and glue is applied liberally instead. The cobweb is excellent for repairing walls for painting; less paint is consumed, but the result is, so to speak, an amateur: when it dries, the structure of the cobweb appears on the surface, and smoothness cannot be achieved in the subsequent series of paintings.
Cobweb for volumetric ceilings
Canvas made from pressed spider web fibers allow you not just to work, but to create. At least it's possible with the materials German quality. With Vitrulan fiberglass, for example, you can get creative by using it for 3D ceilings.
Once in fashion, the volumetric ceiling has only strengthened and developed design techniques over the years. Today there are more of them thanks to modern materials. Cutting fiberglass into pieces, gluing them onto protruding curved areas plasterboard ceiling, you can make a strong and durable surface in the shade you need.
What if a crack does appear?
If the fiberglass is of high quality, like Vitrulan, then if the requirements for laying the canvas are strictly followed, the surface will not crack.
But even if we admit this possibility, the defect can be eliminated quickly: with a patch made from the same fiberglass. To do this, you need to cut a piece larger than the crack by 4-5 cm and glue it on top of the putty. Using a stationery knife, cut in the same way as the edges were removed at the joints of the sheets. The line will thus be drawn through two layers of canvas and putty. Now you need to remove unnecessary trimmings (putty along with the canvas) and glue the patch into the resulting “bald” area. Then work with putty again - apply in two layers, i.e. level and sand.
If the fiberglass is damaged
It happens that the buyer receives a roll that is damaged due to improper transportation or careless storage. Damage to the edges will not affect performance in any way. The web can be glued even to curved surfaces. Therefore, you can cut the pieces in parts and glue them overlapping.
Decent results saving time and money
Perhaps you think that the drywall will not crack, or you want to straighten the seams reinforced concrete floors. In these cases, some crafty craftsmen suggest using fiberglass, cutting it into strips and gluing the joints between the plates with them. The stripes will not be visible after puttying and stripping. Of course, the seams need to be pre-aligned gypsum composition, and then stick the fiberglass web.
However, after trying this method, you will understand why strict adherence to the technology is more reliable, i.e., a full-fledged fiberglass sticker.
If you correctly glue and successfully paint the fiberglass web, the walls and ceiling will be protected from the formation of cracks and emerging defects. This great solution and for decorative plasters. A minimum of problems during the finishing work and a maximum of time between repairs - this is savings.
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 decorative finishing walls The material gained popularity due to its useful qualities, but not everyone has come to a consensus on how to use it and what to cover it with after gluing, paint the fiberglass immediately after gluing it or apply a protective layer to it first.
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 building 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 long time ensure the integrity of the coating of finished walls.
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 from 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 is no controversy regarding the use of gossamer in finishing works produced with state-of-the-art materials does not arise. 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 do not have special knowledge, and especially those who move into a new premises where interior decoration need to be produced 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 should be the same high quality, each layer must certainly dry, and only after that the next one can 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 you need to consult with a specialist about what density is optimal to stick it in specific conditions (private house, apartment in 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 problem areas with putty. 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 the 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 construction knife unnecessary fragments are removed.
- 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 fiberglass and plasterboard fall on 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 hang wallpaper, even more so, you need to prime the fiberglass and apply a putty layer, because the entire texture of the glass fibers will be clearly visible, and wallpaper glue will also go away immeasurably.
In the future large number wallpaper glue may damage 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. The finished composition is 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.
