Fast tiling tool. Tile Leveling System (SVP): Innovative laying technology

Drywall surfaces inevitably have to be putty. Structures made of this material have a large number of seams and joints that can only be hidden with putty. Which one to choose? There are many compositions on the market, but the masters recommend using exclusively those intended for working with drywall.

Such a putty should have high elasticity, environmental friendliness, the ability to withstand thermal expansion and not absorb moisture. Putties vary in ingredients and purpose. They are sold ready-to-use or as a powder mixture.

putty

Putty for drywall is a paste or powder material that is designed to prepare (level) surfaces for the application of decorative finishing materials.

Depending on the purpose, it is customary to distinguish several types of putty for drywall:

Leveling or starting. This is intended for primary or rough leveling - sealing seams and deep cracks, therefore, a composition with large grains.
Finishing or second layer. It is a fine-grained compound with high adhesion to obtain a smooth and even surface. It is used to correct and level small defects and apply a finishing layer. Due white color use decorative trim of any tones.
Universal. This composition has the advantages of the two above-mentioned putties, therefore it is used at all stages of puttying.

Differences in composition

Depending on what kind of base, drywall putty is divided into types:

Gypsum. Such a mixture binds well to the surface of drywall, does not shrink, but is not recommended for use in wet areas. Ideal for dry areas. It sets quickly and holds firmly, but crumbles from moisture.
Cement. It is more resistant to moisture, but shrinks more when dried with the formation of cracks. Used for rooms with high humidity.
Polymer. In all respects, polymer putty is superior to the rest, but it has a high price. It is easy to work with, it does not shrink and is resistant to moisture.

Despite the cost, the latter type occupies a special place in the ranking of professionals. Polymer-based drywall putty has optimal strength and elasticity in all conditions of temperature and humidity. Therefore, it is considered the best for all stages of drywall finishing in any room.

Apply such a mixture with a layer no thicker than 1 mm. The so-called superfinish putty is applied even thinner - 0.3 mm. Therefore, the high price will be covered by lower consumption and quality of the coating.

The conclusion is clear - if the repair is carried out in a room with high humidity, it is better to choose a polymer composition. For a dry room, it is easier and cheaper to use gypsum putty.

Dry mix or solution

Each type has its own advantages. The finished mixture is not diluted with water, but rather thoroughly mixed. But it is more expensive than powder and is used immediately, while the dry mixture is taken in required quantity and dilute to the desired consistency. The shelf life of the dry mixture is higher.

Masters respect ready-to-use putty for the correct consistency, readiness for immediate use and quick drying. In addition, in a tightly closed package, it retains its properties for a long time.

How to prepare putty

Usually manufacturers indicate in the instructions how to prepare the composition. Standard packaging is a bag of 25 kg. For every kilogram of the mixture, it is recommended to add 2 liters of water.

Mixing the solution

The composition is prepared as much as the master will have time to spend in 30 minutes. During this time, the solution will not lose its properties. Warm water (with a temperature of +25 degrees) is poured into a container (bucket) and the mixture is slowly poured into it. Stop as soon as the "slide" of the mixture is a third higher than the water level. Then they wait until it is completely saturated with moisture and settles, after which they begin to knead. Do this with a mixer at 500-600 rpm. This speed is sufficient to prevent the formation of bubbles. Stir with a drill with a special nozzle or hands with a stick. Do this twice with a break of a couple of minutes, each time achieving a uniform mass.

Close up the seams and pits with a thick solution. Check the degree of density by taking it a little on a spatula. If it doesn't drain, it's normal. For finishing, a more liquid consistency is required. Such a solution is easier to stretch over the surface with a thin layer.

Drywall plastering technology

The quality of work with putty directly depends on the implementation of the manufacturer's recommendations. Before applying putty, prepare the surface accordingly.

It is cleaned, degreased, primed (preferably in two layers). Adhesion and consumption of the composition depends on whether preliminary priming has been carried out. Alkyd primer cannot be used for drywall - it deforms the paper layer.

The primer is chosen depending on the type of finish. If drywall is planned for tiles or tiles, then an adhesive composition is used. If under the wallpaper, then deep penetration is better.

Applying putty

Before puttying, make sure that all the screws are screwed in correctly, and that there are no peelings of paper from the gypsum core at the joints of the sheets. If necessary, they are cleaned with a drywall knife and treated with sandpaper. If there is no edge on the sheets, then it is formed by cutting the edges with the same knife at an angle of 45 degrees.

After that, start applying putty:

The seams are closed first. Do this with the help of two spatulas - narrow and wide. First, a small amount of solution is applied to the second and applied to the surface. In the process, they make sure that lumps and bumps do not form, and the solution lays down evenly, covering the entire seam. This will save you from the extra hassle of sanding. We must not forget about the reinforcement with paper tape or sickle. The sickle is glued before applying the solution to the seam. The paper tape is pressed into the existing layer, and covered with another on top.
Then close up the holes from the screws. The composition is applied with a spatula crosswise - along and across.
After that, the corners are putty. First, one side of the inner corner is removed, and after the putty dries, the other. Aluminum corners are attached to the outer corners and smeared with a solution on top.
After the rough layer has dried, they proceed to the finishing putty. This is best done with a wide spatula. Several thinner layers are allowed.

Sanding putty

After drying, the surface is polished to a smooth state. If there are flaws, apply an additional layer. It is not necessary to putty the entire surface. Drywall itself is a flat and smooth material. Check whether additional putty is needed by applying a wide spatula or rail to the surface. If there are no gaps, the surface is flat.

Selection and purchase of putty

Which putty to choose? Last but not least is the quality of the putty itself. At the preparation stage, they get acquainted with the reviews of experienced repairmen and amateurs who used the compositions of various manufacturers. It is better to purchase in a specialized store with a consultation from the seller. Preferably good famous brands such as Knauf.

Polymer putty, due to its cost, is used for finishing. Therefore, it will need less. Take into account the consumption of the composition for square meter drywall surfaces. Approximate consumption of gypsum and cement mixture - up to 1 kg per meter, and polymer - about 0.5 kg. If the repair is done by hand, and even for the first time, it is better to take dry mixes. This will save money and gain valuable experience for working with finished products.

In contact with

Finishing surfaces with drywall makes them almost perfect, but to achieve this effect, you should know how and with what putty to putty drywall. Drywall sheets are non-monolithic.

After installation, joints and seams are formed between them, which must be hidden. Construction hypermarkets offer a variety of putty mixtures.

It depends on them how smooth, straight and durable the wall will turn out, but since not every solution is equally suitable for drywall, it is quite difficult to immediately understand which putty to choose for drywall.

What is putty and its classification

Starting mixtures are used for the initial leveling of the wall

These are powder or paste-like building compounds.

They are necessary for leveling the plasterboard before finishing (or wallpaper).

According to its purpose, putty is classified as:

Starting. It has a large grain size and is used for the initial alignment of planes, sealing cracks and seams.
Finishing. Fine-grained in structure, used if there is a need to apply the last layer before wallpapering. It serves for final plastering, correction of previously unnoticed defects. Creates a perfectly flat white surface, makes it possible to add any tone to the decorative finish.
Universal. It is necessary both for leveling and creating a decorating effect. It can be used almost always. There is only one limitation: in the presence of obvious and large irregularities, it is better to resort to a different variety.

Gypsum mixtures dry quickly and do not shrink

The second important classification occurs according to the main element of the composition:

Gypsum putty. According to experts, this is the most convenient and practical option, because the basis of the gypsum board is gypsum and fillers, which make it more durable and stable. Gypsum mixtures do not shrink, they are easily and simply leveled, they dry quite quickly. To use it, it is enough to pour water into the gypsum (the consumption can be calculated from the table below). Among the disadvantages of this mixture is the rather rapid absorption of any liquid. When it dries again, it begins to crack, so it can not be used in wet areas.
Cement. The most moisture resistant and durable, therefore it is quite common among professional teams. It, thanks to its main component, tolerates sudden changes well. temperature regime. Suitable even for damp apartments and houses, so it can be used in the kitchen or bathroom. Among the minuses: a rather large shrinkage, therefore, if new irregularities and cracks form at the first stage, the process will have to be repeated again.
Polymer putty. Professionals believe that it is more convenient to use than others. This type is used everywhere. It practically does not shrink, so its layer can be used as a finishing layer before applying a decorative one.

The construction mixer will help to quickly stir the mixture until smooth

According to the composition of the putty, they are dry or in the form of a ready-made solution. Each has its own advantages. The finished mixture does not need to be diluted with water, it is enough to mix thoroughly.

It has the right consistency, is immediately ready to use and dries quickly, but it is somewhat more expensive than powder and must be used immediately. The dry mixture is taken in the required amount and diluted to the desired consistency.

The finished putty should be stored in a tightly closed package, but the shelf life of the dry mixture is in any case higher, even if all conditions are met.

There is no definite answer to the question which putties are better. The decision should be made according to the circumstances.

Standard packing of dry mix - a bag of 25 kg. For every kilogram it is recommended to add 2 liters of water.

Dry putty for drywall is prepared for about 30 minutes so that it does not lose its properties. Water is poured into a large basin (temperature - about +25 degrees), the mixture is carefully poured into it until it exceeds the water level by about one third.

Then you need to wait until the powder is moistened and settles. After that, it is necessary to mix the resulting mixture with a mixer (500-600 rpm) until all bubbles disappear. This can be done with a drill with a special nozzle or a stick.

The process is repeated twice with a break of 2 minutes until the resulting mixture is completely homogeneous.

Putty seams and pits should be a thick solution. It should not drip off the spatula. For finishing, a more liquid consistency is required. Such a solution is easier to stretch over the surface with a thin layer.

Drywall plastering technology

Apply the mixture according to the scheme

Before applying putty for GKL, prepare the surface accordingly:

Wipe the wall with a damp sponge or rag, thereby removing dirt, settled dust. If this is not done, the mixture simply will not lay down in the required layer.
Apply evenly. Uneven bumps, any drips or dents should be avoided.

In this case, alkyd primers should not be used. Because of them, the cardboard is deformed, begins to bubble and fall off. This leads to the need to repeat everything from the very beginning.

Under the tile or tile, an adhesive composition is needed, under the wallpaper - a deep penetration composition, as it will perfectly close the seam.

First you need to prepare the putty surface. To do this, check the condition of the screws, whether they are in the right places, whether they are screwed tightly. Make sure that all requirements are met, the paper is held firmly and does not peel off. It is cleaned with a drywall knife and treated with sandpaper. If there is no edge on the sheets, then it is necessary to form it by cutting the edges at an angle of 45 degrees with the same knife. After that, start applying putty.

What determines the quality of putty

Spatula along the seam

The quality of the putty must comply with the manufacturer's instructions for its application:

Putty is bred for about half an hour of work.
Close the drywall seams that form between the sheets. To do this, two spatulas are needed: one for the set, and the second for applying the mixture. To obtain high-quality putty, it is necessary to putty along the entire seam, completely filling it with a solution. Do not allow bumps, uneven dents or holes. Carefully avoid streaks, otherwise the work will have to be redone.
Putty self-tapping screws. The solution is applied immediately both along and across in the form of a small cross. This method allows you to completely fill the available space.
In two stages, the inner corners are removed and puttied. First, one side of the corner is removed, and then, after the putty has hardened, the composition is applied to the second side.
Proceed to the finishing putty, due to which a perfectly smooth surface is achieved. To do this, use the finishing putty, which is applied in a thin layer with a wide spatula. Sometimes several thin layers are performed.
After drying, the surface is polished to a perfectly smooth state. Check the quality of the putty by applying a wide spatula or rail to the surface. If there are no gaps, the surface is flat. Detailed description See all the details in this video:

Selection and purchase of putty

Choose mixtures in specialized stores

When buying, it is important to choose high-quality putty. It is sold in closed packages, and it will not work to find out what quality it is. At the stage of preparation for the purchase, it makes sense to get acquainted with the reviews of professional repairmen and amateurs who used the compositions of various manufacturers. It is better to purchase in specialized stores, after consulting with the seller.

Before you buy this or that composition, read the instructions, find out what it is intended for and what properties it has.

Be sure to find out for which putty surfaces it is suitable.

If a bad mixture is purchased, it is allowed on the first layer, the base one, and a better one is used for the finish. To buy a quality dry mix, you can test it by buying only a few kilograms to start with.

It is difficult to unequivocally decide which putty is better for drywall, since in some cases it is more expedient to use a gypsum composition, while in others it is necessary to use a waterproof material.

Drywall is great construction material which is used by many today. Products are relatively inexpensive, so they are available in any store. But, regardless of this, you should work with the material carefully, because it is fragile. To improve strength and decorative characteristics, drywall is often covered with putty. There are several types of such solutions, so it is important to take into account certain nuances of each of them when choosing mixtures.

Surface features

Drywall is sheet material, consisting of a filler (gypsum) and an outer retaining layer (paper). The sheets have a smooth surface, which attracts many builders, as this speeds up the alignment procedure.

But the use of putty on top of such a product is mandatory.

This is due to several features of the material:

The ends of the sheets are thinner than the entire main canvas. Therefore, when joining several elements in these places, a small depression is formed. It can drastically affect decorative look finishes. Therefore, experts recommend filling it with special solutions.

Drywall fastening takes place on a previously prepared frame. But the base can also have small differences, which will not allow you to get a perfectly flat surface after docking. Sometimes the level of the sheets may differ by 1 cm. This drawback can only be corrected with the help of a full-fledged putty of the entire material.
Drywall has a weak strength, so installation may be accompanied by the appearance of cracks. Close up and strengthen these places with the help of solutions and a special polymer mesh.

Puttying drywall to one degree or another is almost always carried out, as it allows you to strengthen the structure and increase the strength of the upper layer of the material.

Types of putty

Putty is a mixture that is intended for leveling various surfaces and eliminating microcracks. Drywall can be coated with various compositions that differ in technical parameters and operating conditions.

Depending on the purpose, putty for such materials can be divided into several subtypes:

Starting Lineups. They are used for the purpose of rough alignment of the bases. They are distinguished by the presence of large fibers, which do not allow to obtain a perfectly flat plane. Use this type of mortar to seal large cracks, seams and other damage in places where the smoothness of the surface is not of particular importance.

Finishing putty. Fine-grained materials perfectly level the top layer, creating a uniform surface. But these products do not allow you to apply a thick layer, which requires preliminary alignment of the rough base. After drying, the mixture turns white, which allows it to be coated with paints or other similar mixtures.

Universal products. Compositions of this type are used to solve any problems associated with puttying drywall. Mixtures are not always suitable, as they have a rougher structure than finishing solutions, and this does not allow you to control the evenness of the protective layer.

Depending on the consistency of putty for drywall can be divided into 2 main groups:

Ready. Mixtures are sold in the form of semi-liquid solutions that can be immediately applied to the material. The disadvantage of such compositions is their high price and the inability to reuse the product after some time after opening.

Dry. Putties of this type are available as dry mixes. To prepare them, you just need to add a certain amount of water and mix thoroughly. Today, this type of product is very popular. Dry mixes can be used in parts, which allows you to control the flow.

If putties are properly stored, then their service life is practically unlimited. The advantage of dry compositions is also their low cost and availability on the building materials market.

Putty for drywall is made on the basis of various materials.

Depending on the composition, 3 types of such products can be distinguished:

Gypsum plasters. If the composition of the material includes gypsum, which is also present in drywall, then these products can be considered the most suitable for finishing such coatings. Putties are completely safe for humans, as they consist of natural ingredients.

The hardened solution is durable and fast speed drying. But gypsum absorbs moisture well, which can lead to the formation of cracks in the screed. Therefore, experts do not recommend using them in bathrooms and other rooms with high humidity.

cement mortars. Putty is moisture resistant, so it can be laid almost anywhere. Also, the material easily tolerates high temperatures, but it dries for a long time. Experts recommend using cement putties in the bathroom or in the kitchen. To get a quality and even coverage, the mixture is applied in several thin layers that are easier to control.

Polymer putties are made on the basis of various polymers, which allows you to give the necessary physical properties material. Elastic acrylic putty has a high level of safety.

The product is universal, as it can be used in domestic and industrial premises. protective layer resists moisture well, which is very important for drywall, which quickly absorbs water. But it is used relatively rarely, since the material has a high cost.

Manufacturers

The quality of putty depends not only on its composition, but also on the company that produces it. The modern market is saturated with many options for these products, among which there are several main manufacturers:

Knauf. Putties of this brand are distinguished by an optimal ratio of price and quality. The company produces many modifications of solutions, among which are the Fugen and Uniflot models. The first type is made on the basis of gypsum. The mixture dries quickly, so it is very often used for gluing drywall sheets to other surfaces.

Uniflot putty is moisture resistant, as it contains cement. The mixture does not shrink, and is also characterized by high plasticity with a minimal likelihood of cracking.

Volma. The company produces materials based on gypsum. They are used to level sheets and seal cracks. The lineup represented by several brands that differ from each other in composition and physical properties.

Ceresit. Under this brand, many types of solutions are produced, which are of high quality and versatility. Particularly noteworthy are polymer-based mixtures.

How to choose?

Buying putty for drywall sheets is a difficult task.

To do right choice, there are several factors to consider:

Material quality. This characteristic depends mainly on the putty manufacturer. Therefore, before purchasing, it is advisable to read the reviews of builders about specific companies. In this way, you can choose the best value for money.

Operating environment. Many putties are intended for dry rooms. This often includes solutions based on gypsum. For unheated buildings, only a cement or polymer mixture is needed that can withstand temperature extremes and high humidity.

Finish quality. Wall surfaces can have large drops, requiring a thick layer of mortar. The best option here is a gypsum or cement putty. If you only need to form a finishing layer, then polymer-based compounds will do it best.

When choosing, one should also take into account the unevenness of the walls, which will affect the consumption of material. Many experts recommend puttying the ends with a corner. This technology requires the use of compounds that can qualitatively fix the product on drywall.

How to use correctly?

Before applying putty, it should be properly prepared. This applies only to dry compositions, since drywall can be immediately covered with ready-made mixtures after their purchase.

When mixing water and putty, you should follow a few simple rules:

Use only the proportions of water and mixture recommended by the manufacturer. This will allow you to get a solution of the desired consistency.

Add dry foods to liquids, not the other way around. When you add water, small lumps will remain under the mixture from below, which will be difficult to stir and turn into a homogeneous mass.

The technology for applying putty on a drywall sheet consists of the following sequential operations:

Primer. For such materials, special solutions are used that do not destroy the structure of the paper. If too aggressive mixtures are used, then the strength of the structure may be compromised.

Preparation for puttying. Sachala should check if the screws stick out over the drywall sheet. It is important that their heads are slightly recessed into the material. After that, you need to cut off the edge of the product at the joints of the seams to form a recess. This approach will further reinforce these areas.

Sometime for holding overhaul in a private house or apartment, it took a lot of time: to accumulate the required amount, to select high-quality material, to hire professional workers. Today, everyone will cope with this task on their own. Practical drywall sheets are best for repairing and insulating rooms. Various interiors, the expressiveness of the rooms - your imagination is limitless. Partitions are easiest to make from GKL. But, unfortunately, after installation, drywall sheets will not create a pleasant atmosphere in your apartment - the existing chips, cracks, joints, peeking screw heads will spoil the overall picture. But there is a way out - this is putty. A well-chosen putty will solve all the problems that have arisen. The question arises - how to putty drywall ?

Nobody wants to work extra, spend precious time on extra work, so we often think - is it possible to do without finishing putty, because it is much easier to putty only rough? Yes, in some cases it is possible, but not in all.

Every time after working with drywall, we have to close up joints, hide the caps of self-tapping screws, and even out the unevenness that arose during installation. Also, long-term storage of GKL or improper transportation can also make their own adjustments.

The Knauf company, which is one of the flagships of our drywall production market, makes it possible to avoid puttying plasterboard sheets when used under wallpaper or tile, not counting only the corners, joints and the screw heads themselves.

They achieved this goal with the help of a special primer - a water-dispersion paint diluted with water. This primer on the surface of the processed sheet turns into a thin film layer, which is perfectly combined with any type of adhesive, and also protects the drywall from damage in the event of a break in the wallpaper.

Therefore, the question of how to putty drywall is irrelevant if you choose Knauf.

Using a primer for plasterboard

There are a number of significant advantages of a drywall primer. Firstly, with its help, adjacent materials adhere, which greatly reduces the occurrence of bubbles, peeling off the same wallpaper or tile. Secondly, it is evenly distributed over the entire surface, which helps to reduce the consumption of materials.

The primer is always used when finishing rooms, especially when working with drywall, because with its help we improve adhesion with putty, reduce glue consumption when pasting wallpaper. Additionally, a primer is also used after the starting putty, so that the finish layer holds better later, otherwise, you may encounter some problems, such as rolling or falling off.

It is best to choose primers depending on the type and stage of work. Putties are best used with deep penetration properties.

Step-by-step instructions for performing work

When you have finished installing drywall sheets , you have to further finish them. If you plan to paint, puttying drywall should be done in at least two stages.

Drywall plastering technology is as follows:

Be sure to apply a primer with deep penetration properties to drywall.
We close up the holes left from the self-tapping screws.
We putty the joints.
We produce puttying of internal and outside corners.
We apply a primer for GKL.
We finish the surface with a starting putty.
We grind the irregularities.
We apply a primer on drywall.
Puttying with finishing composition.
We cover the walls with a primer for final work.

And now we still find out what putty to putty drywall with. Use both polymer and gypsum. Polymer putties produce a final finish, as they help to level the surface. Gypsum, on the other hand, are both starting and finishing, depending on the size of the grains.

Putty for drywall happens different types- ready for use, or dry, requiring dilution with water. Of course, it is better to use the first one, so you are guaranteed to provide yourself with lumps that can occur with incorrect dry dosages, but it is also much more expensive.

We prime the surface

Even before puttying, you need to prepare the surface of drywall in advance as a dry and clean material. We erase dust, various contaminants with a vacuum cleaner or a damp cloth. We prepare the primer and lubricate the walls with paint tools.

Basically, drywall is primed in one layer, but if necessary, it can be duplicated, as, for example, in the kitchen or bathroom. The following finishing steps can only be started after the applied layer has dried.

We close the seams and screw heads

To seal the seams, special compositions Fugenfuller, Knauf Uniflot, Knauf-Fugen, as well as their analogues are used. These types of putties dry very quickly, so it is recommended to dilute them in a small dose.

It is best to apply putty with a small spatula on the caps of self-tapping screws, in parallel with this, you can cover up the seams.

The edges of the GKL have their own characteristics: along the edge is thinned, and across it is straight. Of course, butt joints are somewhat harder to close, but more on that later.

Vertical joints

First, when sealing the longitudinal joints of drywall with a thinned edge, the space between them is filled with putty.

Then a sickle or reinforcing tape is glued onto the wet putty. This is necessary to prevent possible cracks. When using tape, pre-soaking for a few minutes is necessary. After that, glue the tape to the joint and putty again on top.

Cut seams

It is possible to putty plasterboard with a straight edge at the places of cutting and joining sheets only after processing them before. It is necessary to moisten the edges of the plasterboard with water, and after wetting the gypsum at an angle of 45 °, make small grooves. This work is best done before priming.

Lubricate the resulting joints with a primer, after drying, fill its seam with putty. It is best to use two spatulas 10 and 20 cm. First, smaller, distribute the mixture. The second, more, remove the excess. It is very important to fill the seam well, so that a small tubercle is obtained, protruding above the plane. If so, then everything is done correctly.

Lubricate the seam again using freshly prepared putty. The thickness of the new layer should be about half a millimeter. After that, we attach pre-soaked paper tape for reinforcement to the seam. Remove excess putty with a spatula.

It is necessary to ensure that there are no jams on the paper tape. Once again we collect the excess composition and distribute the remaining putty with a thin ball.

And if so: first tape, after putty?

Some are chasing saving time and money, simply gluing on GKL or self-adhesive mesh, or sickle, or paper tape. In this case, the junction remains unfilled. Such a connection will come out with skewed wallpaper, cracks. In this case, the savings are inappropriate. If apply the right technology, then when gluing wallpaper, plasterboard walls will not fail.

By the way, sickle and self-adhesive have significant drawbacks. Serpyanka cannot maintain the necessary rigidity, it is deformed, stretched. Fabric fibers interfere with the finish, protruding with small wrinkles. The self-adhesive mesh spreads out immediately, without strengthening anything.

Puttying external and internal corners

Puttying drywall corners is an important and crucial moment of finishing. They are trimmed using metal Shitrok and aluminum corners, paper tape and sickle. In the decoration of internal corners, reinforcing tape or sickle is usually used. The principle is the same as in the finishing of seams. The junction is puttied, paper or sickle is attached on top, the excess composition is removed. Then the corner is again finished with the thinnest layer.

Perforated aluminum corners are used to finish the outer corners. It is cut at an angle of 45° or slightly less. The 90° angle is not used. This is done so that the metal does not bulge during operation.

To fix the aluminum corner, putty is applied in small doses at an equal distance of about ten centimeters. The corner is pressed, its position is checked, the excess mixture is removed, bringing it into a flat plane with respect to the entire surface. After the putty dries, the edges are sanded, if necessary, puttied again.

The Sheetrock Corner is more convenient to use as it has a paper base. It is stiffer than paper tape and, unlike aluminum perforated corners, does not lead to sharp drops with the rest of the surface.

Grinding corners and joints

Sanding is a delicate and very dusty business, so care must be taken. Believe you need to curtain with a damp cloth - this will prevent dust from penetrating into other rooms. It is also good to cover the floor with wet rags or wood shavings.

If the previous work was done carefully and in compliance with the technology, then grinding will take a little time.

First, all protrusions are cut off. Then the actual grinding begins. A grinding mesh with a mesh size of 180-200 is attached to the bar. They are doing the work. For better grinding use oblique light. But if wallpaper is planned, then you can grind and not so conscientiously.

It is necessary to use personal protective equipment - goggles, a respirator, gloves. This will save your health.

After grinding, everything is primed again, as the settled dust will interfere with further work.

Do-it-yourself plasterboard putty

To enjoy native home walls in fully, it is better to putty drywall. Your home will acquire a presentable and well-groomed appearance. Moreover, contemplation uneven walls can negatively affect the intra-family psychological climate. Puttying plasterboard walls is a responsible event. It happens that the owner himself is taken for repairs - an unprepared and impressionable person. He has a lot of questions in front of him. The first question is: how to putty drywall, what tools to use? You will need two spatulas - a large one, with a blade length of 40 cm or more, and a small narrow one. GKL putty is carried out in several stages. What putty to choose for drywall at the first stage of work? First, use the starting one. It is applied in a thick layer of 5 mm to hide all flaws and irregularities.

Question two : how to putty plasterboard? We answer - it's a simple matter. Using a small spatula, apply some putty along the edge of the large spatula. Then, pressing the spatula against the wall, we distribute the putty. Repeating in this way, we putty plasterboard walls. Then carefully leveling the surface. The better we do the alignment, the less sanding will be required. After the putty has dried on the drywall, we proceed to sanding. We clean the surface of dust and primer. We use a primer deep penetration. Let it dry again and move on to further work.

How to putty drywall in the second stage? You need to apply a finishing coat. What putty, you decide. It happens on the basis of gypsum or polymers. Finishing putty is diluted thinner and more difficult to use. In order to qualitatively putty plasterboard walls and get the perfect surface, it is best to pre-prime the walls and then everything will be in at its best. The technology of work itself is similar to the first stage. The difference is that putty is applied in a thin layer and quickly leveled. After the plastered walls have dried, they are taken for grinding. This is done with fine sandpaper attached to the bar. For a perfectly smooth surface, side or bottom lighting is used, and preferably with an LED lamp. It will help to identify the smallest irregularities.

Whether it is necessary to putty drywall under the tile, many people think about it before starting the repair. There is only one question here, this is the evenness of the walls, if the deviation is more than one cm, then of course it is necessary.

After that, you need to decide what is better to putty drywall. These are the questions we will talk about today. A video will also be presented in this article, in which you can figure out in more detail what is being done and how.

In building stores today there is a wide selection of putty mixtures. Here the question of how to putty drywall can be solved quite quickly.

There are so many of them that it is not immediately possible to understand which type is suitable for puttying drywall. Some are used for different options for finishing ceilings and walls, others for chipped cracks, and still others for decoration.

Gypsum putties

Thanks to their snow-white color, they are ideal for interior decoration constructions made of drywall.

But these are not all the advantages:

These mixtures have good ductility, which significantly increases their resistance to cracking.
Safe from an environmental point of view.
Good breathability while absorbing excess moisture and giving it in case of shortage - into the room, thus, a favorable microclimate will always be maintained.
They are used in a variety of areas - for sealing joints or irregularities, as well as for leveling.
They have excellent adhesion to other materials.
Easy to sand and apply, dry fairly quickly.

But gypsum plaster also has its drawback - it is forbidden to use it in rooms with high humidity due to high level the solubility they have.

cement putty

When analyzing the question of what drywall is plastered with, this type cannot be ignored. Mixtures made on the basis of cement are not afraid of sudden temperature changes, they seal well and level cracks, chips, seams, cracks, and do not let moisture through.

In their composition, the main binding material is cement, and aggregates (limestone, clay) and chemical additives give the mixture positive characteristics. These properties include high resistance and resistance to cracking.

Attention: All cement putties in their composition have a certain brand of cement, have a certain compressive strength and adhesion with other agents. Ask sellers for such characteristics in advance.

Polymer putty

This finishing material appeared on the construction market not so long ago. The polymer mixture differs from the previous ones in its long service life, good elasticity and its versatility.

Over time, of course, all types of putty crack, but polymer ones last the longest. It should be borne in mind that the price of such mixtures is higher than that of cement or gypsum.

What is the best way to putty drywall?

For this, all three types of putties described above are suitable, but not in every room. For example, if you have to putty a bathroom or kitchen, then it is better to use a cement or polymer mixture. But gypsum putty will not withstand changes in humidity and will crack.

It should be noted that all compounds can have completely different purposes:

Attention: there is one more important point: polymer, cement, gypsum putties may be sold as a diluted or dry mix. Which species to give preference will depend on the decision of the person. But experts advise buying universal dry mixes.

Why dry?

So, we figured out how drywall is putty. Now it is necessary to analyze the technical side of this issue.

Why prime drywall

The thing is that simple glue (like paint) is well absorbed into the cardboard itself. And if such an impregnation reaches the inner layer, then the cardboard, outer layer is simply deformed.

Primer coats create a moisture-resistant film that stops the absorption of paints or glue. After the primer is completely dry (it will take about twelve hours), you can begin to seal the joints.

Execution of works

As mentioned earlier, puttying is a rather painstaking process that should be taken very carefully (if in the end you want your surface to be perfectly even). Here everything is done by hand and then the price of the entire finish will be much lower.

We prepare the surface

If you do not attach importance to this point of work, then it is not right. The durability and quality of the coating will largely depend on this. Therefore, this should be taken seriously. There is only one instruction in the work, to do everything according to the technology.

At this stage, you will need to do the following:

Tighten the heads of the self-tapping screws that protrude to failure.

Attention: The heads should not be recessed into the drywall, they just need to be screwed on. Otherwise, holes will appear. If this happens, then unscrew the old screws and screw in their place new ones, but longer.

If there are delaminations from the filling at the place where the drywall sheets are joined together, then the paper should be torn off under the spine and cleaned with sandpaper. If this is not done, then the putty will peel off along with the paper and cracks will form.
Then it is worth expanding the joints on the sheets. Take a sharp paint knife, and, holding it at a forty-five degree angle, cut about five millimeters from the edge of the sheet. This will increase the adhesion of the putty mixture, which will make the adhesion much more effective.
After that, you can prime the surface. For work carried out with drywall, a special primer is sold. It must be diluted in a bucket and then applied with a roller evenly over the entire surface. The layer thickness should not be less than 0.03 millimeters.

Attention: Never use alkyd primers when working with drywall, because they lead to deformation of the cardboard layer. As a result of this, bubbles will appear on peeled paper, which will hang in tatters and crack. Under such conditions, you can forget about good adhesion with the finishing material.

Step by step work

At the very beginning, puttying of corners and screws is carried out (for this you can easily use a universal, as well as starting putty mixture).

Screws are puttied in a crosswise way, that is, across and along. This will help fill the grooves of the hats better, which will completely cover their heads.
As for the sealing of corners, everything is quite simple here: a plastic soft corner is glued onto the radius structures (on those that have bends), which is additionally fastened with a stapler. A metal perforated corner is glued to a right angle (in this case, putty is also used as a fixing material). Corners are needed in order to seal difficult places the first time, without spending a lot of patience, energy and time on it.
Now you can start applying the first layer. This is done with a wide spatula, stretching the mixture over the surface. In this case, it is necessary to maintain the same layer thickness (this is approximately one to two millimeters).
After the first layer is completely dry, the entire surface is treated with a skin. This is necessary in order to get rid of the excess mixture.
Apply the next layer in the same way.
The next step is to apply the final putty layer. For these purposes, you can use the finishing mixture. After that, we clean the entire surface with a fine sandpaper.
The last thing experts recommend is to once again treat the surface with a primer.

Sealing joints

At the very beginning, fiberglass mesh is glued to all corners. It is very important to ensure that the joint is located exactly in the middle of the sickle tape.

Only after that you can start sealing the joints between the sheets. To do this, use two spatulas: wide (thirty - thirty-five centimeters) and medium (twelve - fifteen). Putty must be applied evenly throughout the entire joint.

It is easier if you first pick up a small amount of the mixture with a narrow spatula, apply it to the joint, and then stretch the putty with a wide one to the maximum possible distance.

Attention: Dilution of putty (if a dry mix was purchased) is best done in small quantities, because it dries quickly enough. And the subsequent dilution of such a mixture with water will change all the original qualities. It is necessary to calculate the approximate amount of putty for thirty minutes of work - this will allow more rational use of the material for finishing. The instructions on the packaging will let you know about the desired proportion.

Conclusion

Now you understand whether it is necessary to putty drywall. Only after completing all the stages of finishing plasterboard structures, you can be sure that decorative trim after some time it will not peel off and will not crack, but will serve reliably.

Doing such work will give you a certain advantage: the design, if necessary, can be quite simply cleaned of old wallpaper and pasted with new ones, while there is no need to carry out finishing works.
