DIY ceiling repair with serpyanka

In detail: do-it-yourself ceiling repair with a serpyanka from a real master for the site my.housecope.com.

For many decades, serpyanki have been indispensable for construction and repair work. They help to avoid the appearance of cracks in new houses, which can shrink in the first years or when repairing cracks that have already formed.

Even 70 - 80 years ago, strips of gauze were used for this. Which was first glued to wallpaper glue, and putty on top. This method was widely used in the repair of walls in "Stalinist" houses. To this day, you can often hear advice on using gauze as a cheaper option. But tinkering with it is difficult, since it is too soft and, when putty, can move away from the wall, leaving irregularities.
Then the manufacturers produced construction bandages, they were already narrow in shape, like a modern serpyanka, were made from the brand and impregnated with a putty compound. Before application, they were immersed in water for a while, during which they were soaked and adhered to the surface. The modern analogue is serpyanka, which is highly durable.

Reinforcing nets for walls help to do the job efficiently, and are simply necessary if temperature drops or high humidity are possible in the room being repaired, since these factors provoke the formation of cracks on the walls.
Corner serpyanki allow you to significantly speed up the work on puttingty knocks, both internal and external. These are the most difficult elements, it is quite difficult to make them even. A flat plastic corner with self-adhesive serpyanka tape on the sides will make the work feasible even for non-professionals.
Reinforcement of drywall seams will prevent cracks, even if finishing with finishing materials will be done in violation of the technological process.

creates a single durable layer of the treated surface;
serpyanka is allowed to be impregnated independently with glue, primer or liquid putty;

Scope of use of serpyanka

joints of sheets of drywall, fiberboard or MDF;
internal and external corners, wall-to-ceiling joints;
cracks and cracks;
at the junctions of slopes with door or window openings.

If a crack is found on the wall or ceiling, it is not enough just to putty. It is likely that the problem area will again make itself felt after a while. It must be pre-reinforced with a special wide mesh or narrow serpyanka.

At first glance, it seems that there will be no problems buying it, since the device is simple and straightforward. But today there are several types of serpyanka and an even larger assortment of reinforcing nets. Importantly, the range of prices is also large. And in order to understand what is needed in a particular case, it is worth considering them in more detail.

All serpyanka that can be found on sale is made exclusively at Russian factories. Therefore, the cost does not depend on the brand, but on the material on the basis of which it is made.

Advice: if the serpyanka is only of domestic production, then the reinforcing mesh can be found from an import manufacturer. This is where you need to be careful. Initially, its cost cannot be similar to our analogue. Therefore, if the seller offers a foreign mesh at a price similar to the Russian one, most likely, you are offered material of inappropriate quality. For example, under the guise of a facade mesh, they can sell a mesh for interior decoration.

Serpyanka - lavsan is used as a basis. It is made by thermal bonding and has good moisture absorption. On average, its density is 50g / m. It will provide the necessary strength when the walls "move" during the shrinkage of the house.
Net - the cloth for it is made of glass threads, and the strength is achieved by their special weaving. To increase the alkali resistance of products, a conscientious manufacturer impregnates them with special compounds. This will protect them from dissolving in an aggressive plaster environment.
Redinka - outwardly similar to serpyanka, but unlike it, it is made on the basis of polypropylene. It is intended when working with thin layers of putty, most often the thickness of which does not exceed 2-3 mm. It is thinner, unlike lavsan serpyanka, it absorbs moisture worse. Density does not exceed 30g / m2.

Reinforcing nets do not have a self-adhesive base, and, unlike serpyanka, are much wider.

Painting net - the thinnest, has a cell size of 2x2 mm. Used for rough plastering of ceilings and walls. It is impregnated with a polyacrylic dispersion, due to which it is highly resistant to an alkaline environment, which means it will not decompose over time. In addition, it has a low weight, but at the same time provides the maximum strength of the future coating.
Plastering and facade mesh - has cells of 5x5 mm. It is intended for the reinforcement of insulated facades, waterproofing layers, self-leveling floors, places where window and door openings adjoin the wall, as well as for the restoration of old plaster coating. Also on sale there is a special reinforced fiberglass mesh or armor, it is intended for strengthening the plaster on the basement and first floors.

If the cell size of the fiberglass mesh is 1x1 cm, then it is also suitable for laying tiles on drywall.

To protect corners or to repair them, there is also a special corner protection fiberglass mesh... It is a versatile material that is equally suitable for reinforcing and reinforcing internal and external corners when plastering indoors and on facades.

For sealing even drywall seams, it is most convenient to buy a self-adhesive tape-serpyanka. Due to the adhesive applied to one side, it is easily unwound from the roll and glued to the cardboard surface firmly, like an adhesive tape and putty. Thanks to its wide mesh structure, the putty easily penetrates inside, completely filling the joint cavity or crack.
Do not worry if the serpyanka sticks firmly, as this fixation is temporary and is intended for ease of use. The fixing compound is a putty.
It is not worth using a self-adhesive serpyanka for reinforcing the seams without putty. Even the sprinkle is thick enough for this and will stand out through the wallpaper.

Advice: you cannot use PVA glue for self-gluing the serpyanka if the work is carried out on top of the screwed drywall sheets. The fact is that this glue is made on a water basis and when it comes into contact with the metal caps of the screws, rust will appear and show through the finish in the form of yellow spots.

When self-mixing the plaster, it is very difficult to accurately calculate the proportions of the components. But this leads to cracking, delamination, etc. In this case, fiberglass reinforcing nets will be able to compensate for this, while maintaining the integrity of the decorative coating.
Do not use paint net to reinforce the facade. Due to the operational features, the manufacturer endows them with different physical and mechanical properties. First of all, the decorative finishing of the facade will carry a much greater load on the mesh than the finishing inside the room. In addition, temperature drops and seasonal importance will also greatly affect.
When buying a reinforcing mesh in a store, first of all pay attention to its density. So, for indoor work, a material with a specified density in the range of 100 - 150 g / m2 and a mesh size of 5x5 mm is suitable. For facades, the density index should be higher than 160 g / m2. Professionals recommend choosing the most durable one for the basement and the first floor, where mechanical damage is more likely.

Tip: a huge assortment of serpyankas and construction nets encourages buyers to choose the cheapest option. Plaster and putty compounds have an alkaline environment, which is aggressive and capable of destroying the material. Therefore, serpyanka must be treated with a polyacrylic dispersion. It is impossible to see it outwardly, but the manufacturer must check each batch, and indicate the data in the passport. Conscientious manufacturers who do not miss this technological moment cannot launch very cheap products on the market.

Summing up, we can distinguish three positions that need to be guided when buying a serpyanka:

manufacturer... If serpyanka is represented almost exclusively by domestic manufacturers, then when purchasing a mesh, this is an important point, which was mentioned above. The cost of imported and domestic fittings cannot be in the same price range;
surface density... With its help, the purpose of the mesh and its strength are determined;
alkali resistance... If the mesh is not properly processed, over time it will simply dissolve in the plaster. This will cause the decorative layer to peel off.

As mentioned above, almost all serpyanka have a sticky side. Depending on the quality, it is firmly glued to the primed surface of the drywall, or it is rather weak. In the latter case, this leads to a decrease in the quality of finishing work. Despite the fact that the serpyanka in the future will be held by the plaster composition, while working with a spatula, it can be accidentally touched and pulled out.
This problem can be solved either by applying additional PVA glue to the surface of the joints.

But it is more rational and reliable to glue it with a cut to the layer of putty, which is supposed to be done.

First, a ready-made putty is applied to the joint of sheets or a crack along the entire length with a thin layer. Apply a serpyanka on top and smooth it with a spatula, slightly deepen it into the composition. Due to its light cellular structure, it easily adheres even to a very thin layer of mortar.

Without waiting for the solution to set, the next layer is applied on top and the edges are leveled so that there are no protrusions in relation to the rest of the wall surface. Do not be afraid that the serpyanka can "move out", it firmly holds in its place. In this form, the putty is left to dry for a day, after which it is cleaned with a float.

Advice: when you need to glue the serpyanka on a very long section, it is very difficult to do it with a single canvas. The thin tape will bend, form irregularities. To facilitate the task, it is initially cut into small segments. So that the strength of the seam does not suffer when reinforcing in this way, each segment should be superimposed on the previous one with an overlap of 1 cm.

Install the serpyanka on the ceiling in a similar way.

Most importantly, when gluing with glue or putty, make sure that it adheres tightly to the surface along its entire length. If there is a discharge, then with further grinding with a float, the mesh will be completely erased and this area will remain vulnerable to cracking.
When gluing the tape to the putty, it is important to make sure that no voids are formed under the material.
It is necessary to cut the serpentine carefully so that the cut is even and long threads do not protrude from it.

Commencement of work to repair a crack in the ceiling

The nuisance in the form of cracks in the ceiling can appear unexpectedly, or it can poison the life of the owners of the apartment for a long time, oppressing it with its constantly growing appearance. Of course, the idea of getting rid of them as soon as possible comes to mind right away, but how to repair cracks on the surface of the ceiling is not always known.

Let's talk about the most common and at the same time well-proven methods of sealing cracks, which will be reproduced not only by professional plasterers, ordinary people will also be able to perform installation on their own. Believe me, among them there will certainly be one that you can master on your own and bring the ceiling in your house into a proper form (read further Draft ceiling).

This method is suitable for those who are not ready to spend time and effort sealing cracks, especially if they are not large. In this case, they can simply be masked. Ceiling tiles are perfect for these purposes.

Masking with ceiling tiles

There are many types of polystyrene foam tiles on sale. It is a very lightweight, practical and inexpensive finishing material. You can perform installation with its help alone. Even if the ceiling has a significant difference in height due to floor slabs, it can also be masked (see Repair of plasterboard ceilings).

Calculating the required number of tiles, as well as choosing their format, will help a simple calculation using the scheme:

Draw a scaled ceiling plan.
Then draw it out with a grid with a cell side equal to the length of the tile side.
Based on the resulting scheme, calculate the number of tiles, including those of incomplete size. You will need to buy a little more, since the tiles that you have to cut may be ruined at first.

Advice! When gluing the tiles, make sure that cracks, as well as differences in the height of the ceiling, do not fall on the joints between the tiles. Otherwise, stick the tiles, you will not be able to firmly.

Of course, neither the mother-in-law, nor the height differences will go anywhere. But the tile will reliably hide all defects, while you will spend a minimum of money and effort on repairs and you will no longer worry about how to remove cracks in the ceiling.

If you are not satisfied with masking the flaws, you will have to carry out repairs. How to repair cracks in the ceiling after many years of service? In cases where the depth of the cracks is small, as well as the number of cracks themselves is small, you can resort to spot puttying. This means that the ceiling will be putty only in problem areas (see Ceiling putty with modern materials).

Crack on the ceiling repaired with spot putty

Spot putty can also be used in cases where the ceiling will subsequently be pasted over with wallpaper. But the wallpaper should be thick, because through the thin wallpaper, the putty areas can shine through. If the wallpaper is nevertheless thin, then the ceiling after puttingtying must be painted with light water-based paint in several layers, achieving uniformity of the color of the entire ceiling.

Cleaning cracks. All cracks must be cleaned of all flaking and crumbling particles and fragments.
The entire surface of cracks and adjacent areas should be carefully primed in one or two coats with a deep penetration primer.
Prepare a putty mortar and repair cracks in the ceiling by filling the grooves with putty and leveling it with a spatula along the surface as evenly as possible.
Let the putty dry for 24 hours.
Sand the filled cracks until smooth.
The ceiling is now ready for finishing - painting, wallpapering, and so on.

Painting the ceiling after finishing cracks

Advice! Repairing cracks in the ceiling is a messy job. Before starting the repair, if possible, empty the room of furniture, and cover the floor with foil.Then cleaning at the end of the work will be much faster.

The first two methods are good for getting rid of small cracks, but sometimes you have to deal with cracks that are very deep and large. In this case, you need to know how to repair cracks in the ceiling so that the structure retains its strength for a long time.When the crack is deep, there is only one way out, fill it with filler. There are several possibilities here. There are several common materials to choose from as crack filler.Since antiquity, it has been known how to repair a crack in the ceiling with the help of improvised means. For example, pieces of fabric:

The fabric was cut into strips and placed in a crack, which had been previously cleaned of all crumbling particles.

A separate piece of fabric with an area larger than the crack itself and ten centimeters wider than it was glued over the crack and the tissue embedded in it.

Today, PVA glue can be used as a suitable glue for these purposes. A crack in the ceiling after repair in this way will be reliably hidden by a layer of putty and will retain its strength for a long time.Sealing a crack with a paint netAdvice! As a material for gluing cracks, a painting net, which has great strength and wear resistance, is perfect.Even a deep crack can be closed with a special sealant. There are sealants on sale for a wide variety of purposes. And you should use the advice of the seller to choose the sealant that is best suited for your particular case. So, the composition of the building materials of the ceiling, as well as the humidity in the room, matters.... The crack is poured with a sealant until it is completely filled, the surface is leveled with a brush or spatula, and after hardening, the excess is cut off with a sharp tool.Repairing cracks with a sealantIt should also provide for the likelihood of cracks at the joints of walls and ceilings, arched openings. If there are already cracks on the ceiling, then there is a high probability that cracks will appear in these critical places in the future..Prophylaxis can be done with the help of a serpyanka.

It is important to carefully putty all surfaces before gluing it. This is done in order to avoid further bubbles.

A serpyanka is glued to the putty surface, which, after drying, is also putty.

This method of processing corners and joints has proven itself in practice and allows you to forget about repairing the ceiling for a long time.

Advice! Cracks in the ceiling may indicate leaks in the sewage system, shrinkage of the building, violation of the strength of the floors. Sealing one crack will not prevent the emergence of new ones, unless the cause of their appearance is eliminated.... Having found a crack, consult a specialist to determine the cause of its appearance.No ceiling type is immune to cracking. They can occur on both concrete pavement and suspended structures.Consider how and what to repair the crack on the ceiling - putty or drywall. The reasons for this unpleasant phenomenon:

shrinkage of the house;

sewer leak;

mistakes of a construction organization or a repair team;

sharp temperature drops.

Shrinkage of a new building is a lengthy process. It can drag on for several years, during which the problems with the ceiling will only get worse.The reasons why cracks appear on the plasterboard ceiling:

improper putty of the gypsum board surface;

weakening of the frame;

deformation of non-moisture resistant drywall under the influence of moisture;

during the course of sealing the joints, no plaster mesh was used or the work was carried out in violation of the technology.

Ideally, this task should be assigned to a specialist.In the course of an expert study, competent persons will assess the state of the ceiling, identify the true cause of damage and determine the dynamics of propagation.

If you cannot resort to the services of specialists, then begin the assessment with a visual examination. It will help you find out if cracks have appeared at the junction of the slabs.

Next, remove all lagging layers with a spatula. This step will determine the depth of the damage.

Small cracks that can be eliminated through cosmetic repairs include damage whose depth does not exceed 1 cm.

How to repair small cracks in the ceiling on your own? There are 3 ways to repair minor damage:

spot plastering (carefully cover each one);
masking cracks by sticking materials over the damaged area;
installation of hinged structures.

The last 2 options are global in nature, so we will focus on the more affordable spot plastering.

putty knife;
deep penetration primer;
serpyanka;
plaster;
sandpaper.

Ceiling preparation. It should be cleaned of dust and lagging pieces.
Primer. Better to apply several layers. Make sure the previous one is dry before applying each new coat.
Crack filling. Remember to align.
The use of a serpyanka.
Re-puttying.
Expectation. Let the putty dry. This will take a day.
Elimination of visual defects. Use sandpaper.

Textile. It is laid in a previously plastered crack.
Serpyanka. It is used over fabric.
Putty. It is used 2 times: for filling cracks and on top of a serpyanka.
Polyurethane foam or sealant... It is applied over the putty serpyanka.

With a crack along the seam, the algorithm of actions is different:

cleansing the seam;
expansion of the seam;
alignment of the seam;
primer;
filling the seam with polyurethane foam;
cutting off excess;
reinforcement with construction mesh;
leveling with putty.

With a plasterboard ceiling, the work plan will be as follows:

Elimination of putty.
Crack expansion up to 5 mm.
Cleansing cracks from dust and paint.
Primer.
Fugenfüller application (special putty mixture).
Expectation. You must wait 24 hours.
Re-priming.
Puttying.
Painting the entire ceiling.

What to do if repairing ceilings is a favorite pastime:

save on building materials;
do not trust anyone to renovate your home. No specialists can handle this better than you;
do not prime the ceiling;
do not let the previous layers dry. This is a waste of time, the “fresh” layer “sits down” better and better;
do not hesitate when choosing a primer and putty. They are versatile, suitable for all types of surfaces and materials;
if you live on the top floor, be sure to choose non-moisture resistant drywall;
believe in redecoration. It will help with any type of cracks and ceilings;
ignore smudges and mildew;
masking cracks is our everything;
do not assume that the cracks are due to a violation of the structural integrity of the house. In your case, the reason is less global, and therefore you should not waste energy on eliminating negative factors;
order a stretch ceiling. If the cracks in the slabs are not visible, then everything is fine.

Recommendations that should be adopted if there is a desire to prevent the appearance of cracks:

Installation of gypsum cardboard should be carried out in strict accordance with technological requirements.
Trust the professionals.
Check the suspensions before installing drywall. Only start work if they are well secured.
Fasten drywall sheets with self-tapping screws at equal lengths.
The sheets should be fastened every 10-15 cm.
Remember to chamfer all sides of the sheet.
Prime the seams with a primer. A deep penetration primer is best suited.
Finish seams prior to using the plaster mesh.
Use acrylic filler when filling cracks.
When choosing a sealant, remember that silicone options will not stain.
If there is fungus on the ceiling, seal the crack with sanitary sealant.
Apply a continuous plaster mesh. Try to make sure that the ceiling is covered with a single canvas.

You can also remove minor damage with your own hands. However, in no case ignore the dynamic deterioration of the situation and cracks in the slabs themselves, and not at their junction. Perhaps, in your case, repairing the problem will not be possible.

One of the main stages of preparing a plasterboard structure for finishing is the sealing of the seams. This process is simple, if you strictly adhere to the recommendations of drywall manufacturers. If we step back at least one step from the technology, then the simplest defect that appears during operation is a crack at the junction of two sheets. Therefore, it is necessary to pay special attention to the sealing of drywall joints.

What is required to seal the joints?

Two spatulas: one wide, one narrow. The first will be putty on the seams, the second this material will pry out of the container and applied to the working edge of the first spatula.
Clean dishes for the putty.
Roller or brush for applying the primer.
A plane with which the edges (edge chamfers) of sheets will be cut. This tool is required even at the installation stage. Once the sheets are stacked, it cannot be used.
Sandpaper for sanding.

putty;
serpyanka tape or paper reinforcing tape;
deep penetration primer for drywall applications - choose an acrylic material for interior use.

With regard to the choice of putty for the joints of drywall sheets, pay attention to the following:

First, a solution is needed specifically for GCR.
Secondly, the universal option is best suited. This material is used for both leveling and finishing.

You can buy two types: leveling (with coarse grains) and finishing (finely dispersed). The joint is filled with the first, the finishing is carried out with the second for the finishing cladding. That is, two options are acceptable, whichever is convenient.

The only thing I would like to draw attention to is the state of the material itself. They are available dry. These are mixtures that must be diluted with water in the proportions indicated on the package. There are ready-made solutions, but they are more expensive.

Experts also recommend using putties from the Knauf company for sealing drywall joints. These are Uniflot or Fugenfüller solutions.

There are certain conditions under which the end result will only be positive.

Firstly, it concerns the indoor temperature. It must be at least + 10C. In this case, the duration of the temperature regime must be maintained throughout the entire period of this type of work. That is, temperature jumps are unacceptable.

Secondly, drafts are prohibited. Do not open windows and doors when sealing drywall joints.

Thirdly, there are certain restrictions regarding the humidity inside the room. Therefore, the installation of drywall and the sealing of its seams can be carried out only after pouring the floor screed, leveling the ceiling and other wet processes. And the thing is that high humidity is the reason why the putty will not bond well with drywall.

Fourthly, the fastening of the gypsum board sheets to the metal frame must be carried out in accordance with all the rules. Weak fastening is the reason for the separation of the sheet from the frame, and, therefore, a crack at the joint at any slightest load. Neither putty nor serpyanka tape will help.

The chamfer on the edges of the plasterboard sheet is made on purpose, thereby expanding the joint. So this groove must first be primed.This is done in order to strengthen the exposed plaster layer, plus increase the adhesion of the edge surface.After drying, the joint is filled with putty to the brim. Serpyanka tape is installed immediately. In fact, serpyanka is a reinforcing frame. It looks like a medical bandage, but is made of polymer.Read How to glue two types of wallpaper in the hallTo glue the serpyanka on drywall, it must be laid on a wet putty mortar. It is mounted exactly in the middle, evenly covering the edges of two adjoining sheets of gypsum board. After that, it is necessary to give time for the putty layer to dry well. Next, another layer of putty is applied.After it dries, the treated areas are polished with sandpaper. And the last stage is the primer. On this we can assume that the putty of the drywall joints is finished.So, in this article we tried to answer several questions: how and with what to putty the joints of drywall? This process is simple, you yourself could see for yourself by reading the article and watching the video. We propose to have a little discussion on this topic. We are very interested in your comments.When making any structure from drywall, and approaching its final finish, one should not forget about such a necessary material. like a serpyanka. It will make it possible to qualitatively and reliably reinforce the seams between its sheets, make them strong, and prevent cracking, which are often formed when the processing technology is violated.Most of us do interior decoration and repairs on our own, relying on our experience and the advice of friends, but not everyone knows how to glue serpyanka on drywall correctly.When reinforcing and sealing joints, seams or gaps between plasterboard sheets on the wall and ceiling, you need to know how to glue serpyanka on drywall. Serpyanka is a flexible and fine fiberglass mesh tape (less often lavsan).It is used for the reinforcement of gypsum plasterboards in the installation of any type of structure. It was impregnated with an adhesive that allows you to easily and quickly apply to the surface evenly and without swelling.Serpyanka is simply indispensable for the interior decoration of an erected structure or for repairs. It belongs to multipurpose materials and is used as a reinforcing base. It is simple and easy for her to perform many types of work:

Repairing cracks

Manufacturing of door or window slopes

Finishing of joints of building material parts

Sealing joints or seams

Reinforce internal walls, ceiling

Fix the junction of the window (door) frame to the wall surface

The features of this material include:

Resistance to the influence of aggressive environment.

High strength index.

Increases the service life of the reinforced material.

Forms a strong and reliable adhesion with the binder.

Withstands shrinkage, vibration, surface displacement, high humidity and temperature extremes.

It adheres well to any surface, it is easy to cut with the usual tools.

It is durable, has a low cost.

Perhaps it loses in some way to other reinforcing materials, but its wide field of application and advantages only confirm that this mesh is a convenient and reliable material to use.Spackling the ceiling of an unusual shapePlasterboard is used in the manufacture of modern ceilings with various shapes.The surface and shape of the ceiling is always eye-catching.Therefore, the result of the work performed should be the ideal evenness of the ceiling, the clarity of the shapes and lines of bends.To achieve this result, it is necessary to understand the question of how to glue serpyanka on drywall to the ceiling.Giving a flat surface to the ceiling will help to accurately fill the seams between the drywall sheets. The specialists have a secret that will help to achieve the expected result.Read Glass partitions in a studio apartmentBefore puttingty, a layer of cardboard should be removed along the seams to a width equal to the width of the serpyanka. To make it easier to remove the cardboard, it can be moistened with water.Plastering plasterboard ceiling is performed in the following order:

Prime its surface

Give it time to dry well

Apply the first layer of putty to the joints.

Lay the serpyanka

Apply the second layer of putty on the laid serpyanka

After it dries, the surface is sanded with fine emery paper.

When sanding a ceiling, it is important to achieve an imperceptible and smooth transition from the seam to the surface of the sheet. You can apply this technique and process the areas where drywall is attached to the ceiling. After finishing puttying, you can proceed to finishing the ceiling.A little advice. To avoid peeling off the tape from the edges under the influence of gravity, a layer of primer should be applied to the ceiling thicker, and the tape itself should be coated with PVA glue.A well-performed repair is always a big financial cost.Therefore, it is important that after its completion, the result of the work pleases as long as possible.Serpyanka is considered to be the material that will keep the walls and ceiling in perfect condition for a long time, preventing the appearance of cracks and cracks.But in order for the renovated room to be in good condition as long as possible, you need to know how to properly glue the serpyanka on drywall.When gluing the tape, the technological sequence should be observed:

Cut the material to the required length.

In accordance with the instructions attached to the putty. knead it. It is not necessary to knead a lot, as it quickly hardens and becomes unsuitable for subsequent work. One-time cooked volume should not exceed 1.2 liters.

Using a spatula, apply the first base layer of putty along the length only in the seam between the sheets.

Then, on top of the sealed seam, the serpyanka tape is laid with the glue side down. In this case, you can smooth and direct it with a spatula. You can lay it in two ways:

When laying it on the seam, it is necessary to gently press the serpentine into the middle of the seam.

Lay on a dry layer of putty. In this case, the surface of the putty is first sanded, primed, and then the tape is laid.

When gluing the tape, it is important to make sure that no voids are formed underneath, which will cause cracking of the seams.A second layer of putty is applied over the laid serpyanka with a spatula.The layer should not be thick, otherwise the tape will not be able to contain it and over time the putty will crumble.When the putty dries, all irregularities should be removed with sandpaper or a special sanding machine.If you correctly and accurately follow the technology for performing the work, then the end result will justify the expectation.Obviously, serpyanka is a lightweight and easy-to-use material. It allows you to efficiently and reliably carry out finishing and repair work. At the same time, it is not necessary to have special knowledge and skills in work.A master class on sealing seams is presented in the video:First, let's figure out why you need it in the seams serpyanka and what she is. When installing drywall, technical seams will inevitably form between the sheets, and after filling them, cracks may form, and this is unacceptable. Especially when it comes to a suspended plasterboard ceiling. which will subsequently be painted. So here serpyanka It is a self-adhesive mesh tape to prevent cracking. In fact, it is a kind of reinforcement, it also holds and holds the solution, in our case it is gypsum plaster and finishing putty.Read Plasterboard partitions in the roomBefore proceeding, I remind you that the entire surface, whether it be the ceiling or walls, should be primed, and only after the primer has completely dried can we proceed to sealing the joints.Here is a complete list of tools and materials:

Spatula for 80mm and 450mm

Container for dilution of the mixture

Stationery knife (cut the tape)

Serpyanka

Gypsum plaster

Primer

All of the above or any other tool or material can be purchased at a significant profit thanks to the cash back service. To return part of the money you spent in almost any online store, sometimes up to 30% from each paid purchase, is a very useful proposal to save.For me personally, there is two ways of mounting serpyanka... One is simpler and faster in execution, the other is more complicated, but at the same time reliable in terms of durability of operation. In other words, there are more guarantees that there will be no cracks. Let's consider both options in order.First option. Starting from the top (if the seam is vertical) glue the tape while simultaneously unwinding it to the bottom. At the bottom, near the floor, cut with a knife with replaceable blades and press the end. This is the same as sticking masking tape, the serpyanka is just as sticky on one side and adheres perfectly to the seam surface.If, nevertheless, the tape does not hold and falls off, this means poor manufacturing of the adhesive base. Do not rush to get upset, you can stick it, but the second option is described below. This also happens due to the dust on the drywall, the reason for this is that you forgot about the primer.So, it remains to cover up the seam with the glued strip of gypsum plaster. Do this job with two spatulas, one small 80mm and the other 450mm larger. I advise you to mix the solution with a mixer, so the solution is guaranteed to turn out without lumps. Do not knead too much of the mixture, the fact is that it tends to set quickly (after about 15-20 minutes), one liter is enough for you, when the solution is worked out, mix the same amount again.After the seam is stretched out with plaster, give it a good time to set, then you can proceed to puttying the entire surface without waiting for it to dry completely. By the way, the caps of self-tapping screws recessed in plaster should also be coated with plaster.Second option. We absolutely do everything as in the first, but there is a main difference. Serpyanka will not be on drywall, but, as it were, in the middle of the mixture. That is, first we lightly coat the seam with gypsum plaster, pressing it into the gap between the sheets, then press it with a spatula (just slide it over) the serpentine along the entire length.
