When covering walls and ceilings with plasterboard, gaps inevitably remain between the sheets of material. And so that these gaps do not appear under paint or wallpaper, in mandatory Drywall seams should be treated with a special putty.

Sealing cracks in drywall is not particularly difficult, but at the same time it requires careful execution. In the article we will describe in detail the sequence of grouting operations, and also focus on some of the nuances on which the quality of the final surface depends.

Grouting the ceilings

Preparatory work

Tools and materials for plasterboard putty

Before you begin preparing the sheathing for finishing, you need to decide what to use to cover the drywall seams, and also purchase the necessary tools.

Most often used to perform this operation:

Material for sealing cracks

• Putty for gypsum board. The most widely used materials are Fugenfüller, Uniflot, Fugenfitt, etc.
  They ensure reliable fastening of the gypsum board edges and prevent cracking of the seam under the finish after the putty has dried.

Note!
If you plan to apply interior paint over plasterboard sheathing, then it is better to use more expensive compounds to seal cracks and uneven walls.
To level the wall for wallpapering or decorative plaster, you can use compounds whose price is in the cheaper segment.

• Reinforcing serpyanka tape. Used to seal seams and prevent damage.

Serpyanka ribbon

• Metal corner covers. They perform the same function as serpyanka, but protect the edge of the gypsum board more reliably.

We figured out how to cover drywall seams, now we need to select the tools to complete this task:

• We perform the procedure of filling the seam using a spatula. It's better to have several spatulas on hand different sizes– this way it will be possible to carefully fill in small uneven areas and treat a large area.
• To work with seams and cracks on the ceiling, we will need a falcon - a special plate with a handle on the underside.
  You can lay the putty mixture on this plate and gradually pick it up with a spatula to fill the cracks.

Sokol plastering

• A grater with an abrasive mesh is used to polish the rubbed surface.
• To control how well we apply the putty, we need a level. In this case, it is better to take an ordinary level with an air bubble, since a laser level is practically not suitable for this purpose.

So, we have something to grout drywall seams, ready necessary tool– which means it’s time to get to work.

Preparing seams for grouting

Before grouting seams on drywall, they must be prepared in a special way - otherwise the grouting compound will not penetrate the seam, and therefore will not provide sufficiently high-quality adhesion to the plasterboard sheathing material.

Ideally, preparation for grouting joints is carried out at the cladding stage:

• After cutting, the edge of the plasterboard board is carefully processed with a plasterboard planer. This is done in order to ensure the most tight joining of the plates to each other.
• When the edges are processed and leveled, lay the slab on flat surface and using an edge plane we remove the chamfer at an angle of 450. The width and depth of such a chamfer should be from 5 to 10 mm, depending on the thickness of the plasterboard.

Chamfering with a paint knife

• We fix the chamfered slabs to the drywall frame using self-tapping screws, making sure that each slab is securely fastened.
  The greater the “free play” of the edge of the slab, the more difficult it is to fill the joint efficiently and the higher the likelihood of it cracking.
• If we need to seal cracks in a wall that has already been covered with gypsum board, then the jointing of the drywall is done using a painting knife. Having positioned the blade at the selected angle, we process the edges of the sheathing sheets, forming a v-shaped recess.
  After the chamfers at all joints have been removed, it is necessary to treat the surface of the wall or ceiling with a primer. Of course, you can do without this component, but a high-quality primer ensures more effective adhesion of the putty to the gypsum core of the sheathing sheets.

• When the primer is completely dry, seal all joints with sickle tape. As a rule, fiberglass tape comes with a self-adhesive coating, so its application should not cause any difficulties.

Sealing an embroidered seam with serpyanka

• The serpyanka is glued exactly in the middle of the joint, and sections of the tape should not be allowed to sag. The connection of several tapes must be overlapped, and the edges must overlap each other by at least 4-5 mm.

Advice!
Instead of sickle tape, you can glue the joints with strips of gauze or paper. In this case, naturally, the quality of the surface will be significantly lower.

• Also, at the preparation stage, we glue all internal and external corners our plasterboard construction.
  An alternative to the serpyanka, as we noted earlier, can be a perforated metal corner (pictured).

Protective corners

Processing joints of plasterboard sheathing

Preparation of putty

For this:

Mixing putty

• Pour into a clean container (it is best to purchase a box specially repurposed for this purpose) tap water in the quantity indicated by the instructions from the manufacturer of drywall putty.
  The water should be at room temperature.
• Pour the dry component of the mixture into the water and thoroughly mix the composition using a drill with a special attachment. The rotation speed of the drill should not exceed 600 rpm.
• Leave the mixture for 5 minutes, then stir again. The time to use the putty prepared in this way is about 2 hours, therefore, for large volumes of work, it will be more rational to prepare the composition in several steps.

Note!
After the putty mixture has dried, adding water and re-mixing the composition is not allowed!

Seam putty

When the grouting composition is ready, we begin to apply it:

• First, we put enough on the falcon a large number of putty mass - so as not to run every minute to the box for a new portion.
• Having collected a small amount of the composition from the falcon with a spatula, rub it into the gap between plasterboard boards. In this case, you need to ensure that the mixture is pressed through the cells of the serpyanka. You can learn the technique of grouting from the video materials on the website.

Grouting the gap using serpyanka

• We continue filling the gap between the gypsum boards until the entire seam has been processed entirely. After the putty begins to set, take a wide spatula and remove the excess, leveling the layer.
• We separately process unevenness in the plasterboard sheets, their damage, as well as the places where the screws are attached to the frame.

After applying the putty, let it dry, and then repeat the operation, applying the finishing layer. If there are significant unevenness or sufficiently wide gaps between the plates, the number of layers of putty can reach three, and sometimes four.

We level the finishing layer using a wide spatula, after which we make sure to check the plane of the surface with a level.

What are drywall joints, how are they processed and what is the technology for carrying out the work? Some recommendations, as well as applicable putties for joints.

What to do with drywall joints on the wall

One of the most popular finishing materials is a plasterboard sheet.

It is distinctive in many of its properties. Suitable for leveling walls, creating multi-level ceiling structures, production of arches and furniture.

After installation of HA sheets, seams appear. What to do with drywall joints on the wall and how to carry out the work is described below.

When drywall joints appear on the wall

You can work with GC sheets using one of the following methods:

• Frame installation of gypsum boards;
• A frameless method of fixing drywall to a surface.

Frame method - creating a sheathing from metal profiles And additional materials for sheathing with sheets. Still in use wooden slats, but less often, since wood is a capricious material that requires certain conditions for work and processing.

The frameless method involves gluing sheets to the base using various adhesive mixtures and not only.

In both cases, after installing the HA sheets on the base, seams appear - a border between 2 sheets.

The joint must be correctly formed:

1. the gap between the sheets should be no more than 2 mm;
2. there should be a chamfer - a kind of groove along the entire border. The plasterboard sheet has a rounded edge, but if the sheet is cut, the edge is immediately cut at 45 degrees with a plane (milling cutter). Masters, in a hurry or because of laziness, do not create this chamfer. Then construction knife You need to make a recess yourself at the borders of the sheets.
3. The joint on the gypsum board must be smooth, without cracks or deformation.

Chamfer plays important role. It increases the rigidity of the plasterboard surface. A properly sealed joint is a guarantee of the strength of the entire structure.

How to seal

Sealing joints on a plasterboard surface involves 3 steps:

1. Purchasing materials and assembling a set of tools.
2. Preparing the seam for reinforcement.
3. Step-by-step plan for completing the work.

To reinforce joints you will need a set of tools:

1. brush;
2. putty knife;
3. a clean container for diluting the mixture;
4. construction knife with a sharp blade.
5. Sandpaper.

Materials needed:

1. primer;
2. reinforcing mixture;
3. reinforcing tape, corner (aluminum corner profile PU 25x25);
4. clean water at room temperature;
5. mixture for joints.

All tools and containers must be clean. Working with a dirty tool is difficult and does not give the expected results.

There are several options for reinforcing tape:

• Serpyanka is similar to a medical bandage and is durable due to its composition.
• Paper - manufacturer KNAUF. When wet, it does not lose its properties.
• Non-woven - contains fiberglass.
• Tape with a metal insert - used to reinforce the corners of gypsum boards.

After collecting everything you need, you can start preparatory work with a joint. It consists of several steps:

1. The seams must be chamfered and clean. Use a brush to clean the border of the sheets from dust, and carefully remove small pebbles of plaster.
2. Cover the seams with a clean brush and primer mixture. This must be done carefully so that the primer fits well into the seam. The corners of the plasterboard structure are also treated.
3. Need to give time to dry primer mixture.

After drying the joint, the main work begins.

To do this, dilute the mixture for reinforcing joints according to the instructions on the package. Mostly they buy Knauf Fugen.

Next, use a medium-sized spatula thin layer apply the mixture to the joint. Glue the tape on top so that it lies centered along the seam. Using a clean spatula, press it slightly into the damp putty on top, thereby collecting the excess.

The next step is to cover the tape with the same mixture. Without waiting for it to dry.

The remaining putty is used to cover the fasteners. The caps of the screws are “recessed” into the drywall by 1 mm. All areas are treated with primer.

Self-adhesive sickle tape is fixed to the plasterboard surface without putty. After gluing, it is covered with a putty mixture.

All work done is left to dry completely.

How to cover seams

KNAUF Uniflot mixture is used for sealing joints without reinforcing tape. Its differences:

• The strength of putty is comparable to cement.
• It is light in weight, so it is used on plasterboard surfaces.
• The putty does not allow or absorb water.

The diluted solution is applied to the joint in one layer. If between plasterboard sheets there is a gap of 2 mm, then apply 2 layers. Work with the mixture for 25 minutes, after which it hardens.

If you intend to hang a heavy object on a wall made of GC sheets, then the craftsmen recommend using Knauf paper tape with this putty to make the structure more durable.

Another putty mixture is JS weber vetonit. It is a polymer composition that has a strong adhesion to the plasterboard surface.

The principle of operation is the same as with KNAUF UNIFLOT. However, craftsmen do not recommend using putty mixtures without reinforcing tape.

Sizing with serpyanka in the corners of plasterboard walls

The corners of the plasterboard structure are carefully reinforced, since they bear a large load.

Internal corners may become deformed due to building subsidence.

External corners are subject to mechanical stress (impacts).

Before applying serpyanka to the inner corner, it is cleaned of dust and thoroughly treated with a primer.

Using the mixture to reinforce the joints, glue the serpyanka and cover the top with putty.

Serpyanka is used in small corners - created niches, podiums, shelves. To reinforce the internal corner from the ceiling to the floor in the room, use a tape with a metal insert.

The outer corner is best protected with a perforated corner corner. Putty is applied to the cleaned, primed corner. They put a corner on it and “sink” it in well. From above, without drying out, the corner is covered with the mixture. Everything should dry out. This will take no more than 10 hours.

Is grouting of joints necessary?

After the joints on the plasterboard wall have dried, subsequent grouting is carried out. This is what you need to do:

1. The remaining stones from the mixture will interfere with subsequent work and may ultimately ruin the appearance of the room.
2. Grouting must be done to achieve a smooth surface.

Grouting is done on a dry surface sandpaper or a sander. For convenience, so that all defects are visible, use a lamp.

After the work, the surface remains smooth and clean.

When to start subsequent work

After the work has been done on reinforcing the joints, as well as grouting them, you need to thoroughly clean everything from dust, cover it with a primer, and only then start working.

The entire surface of HA sheets is covered with a finishing putty solution. After complete drying, use sandpaper and a grinding machine to remove small stones and other defects from the surface.

Before applying decorative coating (paint, wallpaper, decorative plaster, tiles) the surface is primed again.

Recommendations from the experts:

1. After grouting, small cracks may appear on the plasterboard surface. This happens due to temperature changes. If cracks are found, they must be covered with a thin layer of joint putty.
2. When the soil moves or the house subsides, cracks appear in the corners. They must be reinforced and then puttied.
3. The packaging of putties often contains the inscription: “Use without reinforcing tape.” To achieve strength, it is worth using tape for gypsum board joints.

After all of the above, it is clear that the joints must be reinforced with tape and putty intended for this purpose. Grouting joints is required for good appearance, and the corners must be reinforced with a corner profile and tape with a metal insert.

Useful video

There is no doubt that plasterboard is a very popular material used for interior decoration. But it is not the end result of such work; there will be more decorative layer. This means that the surface must be carefully prepared. Sealing drywall seams requires special attention. Much attention is paid to this stage great importance, initially everything needs to be done correctly.

When starting any work, it is better to prepare everything in advance. You need to pay attention to the tools minimum set of which is:

1. A set of spatulas - it is better to choose three main ones: wide, medium and narrow. The first one will do the least amount of work, but it is very convenient for smoothing out seams.
2. If you wish, you can add a falcon - a special device for working with putty. It is a flat plate with a handle. It is convenient to take the solution from its surface. Although, a wide spatula will perfectly fill its role.
3. Level.
4. Drill with mixer attachment.
5. Brush and .
6. Block and sandpaper.
7. Construction knife.

Tools for sealing drywall joints

We must not forget about the materials, of which there must be the required quantity:

• Two types of putty compounds:
  Starting. It will be used to seal the drywall seams.
  Finishing. This mixture will not be used to seal drywall joints. It is needed to apply a control layer that will make the surface perfectly smooth.
• Primer mixture. It is better to prefer acrylic.
• Special tape - mesh (serpyanka). It will be used to seal the joints of the gypsum boards. And it is needed so that the putty does not cause cracks in the future.
• We must not forget that there are also corner seams. Therefore, it is better to have special perforated elements. And also reinforcing tape for corners.

Only by putting everything together can we say that the time has come to do the work yourself. The sealing of drywall joints should not be interrupted due to the absence of something.

Advice! When choosing a putty, they focus on the final decorative coating. So, you can choose a cheaper dry mixture for wallpaper. In any case, it is better to give preference to gypsum-based putty. This is a reliable composition that is well suited for such work.

Working with seams

Sealing drywall seams has its own characteristics. To do everything correctly with your own hands, observe the following conditions:

1. Optimal performance indicators are observed, which are indicated by the manufacturer on the putty packaging.
2. Drafts should not be allowed to occur.
3. Plasterboard slabs must be checked for reliability of fastening to the wall (profile). Any “walking” of the sheet will lead to the destruction of the layer of putty mixture, even when applying tape (mesh).

Now the puttying of drywall joints begins, divided into several stages.

Joining

This process is the processing of the edges of the material. The goal of the event is to obtain a surface that will be as suitable for work as possible. A construction knife is used.

1. In places where two sheets of drywall meet, remove all excess (cardboard scraps, broken areas).
2. They begin to cut the chamfer. Do this at an angle of 40-45 degrees. That is, the joints of the plates should resemble one well-known symbol - a “tick”. It is more convenient to do this before fastening. Although, there is nothing to be done after.

On a note! There is gypsum board on sale, the edges of which are already processed at the required angle.

Primer

It is believed that priming is optional, but this is not entirely true. Yes, gypsum board has sufficient adhesive properties that will hold the putty layer and the subsequent decorative layer. But why take the risk? The cost of such compositions is low, they are applied quickly.

It would be correct to choose an acrylic-based mixture. It has good penetrating properties and dries quickly.

If you plan to paint the surface, then priming is mandatory.

Caulking seams

Sealing drywall joints begins with preparing a dry mixture. It is diluted with water and stirred well. After letting it stand for a while, the procedure is repeated. They prepare a small amount - only for an hour of work.

Attention! Serpyanka tape can be used in the work, and there is also paper reinforcing tape for drywall. They are similar in their parameters, but the latter is used with increased requirements for the resulting seam. For convenience, choose self-adhesive products.

The process technology is as follows:

• To make it easier to work with joints, you can take a small container and put a little putty into it. So, it will work faster and more conveniently.
• So, take the mixture with a medium spatula; you need to literally hold it on the tip. And smoothly smear it into the seam.
• It is necessary to ensure that the solution completely occupies the volume of the joint.
• Now cut the tape, which is glued directly to the seam. It should go down the middle.
• The serpyanka is pressed a little. Next, apply another layer along the entire joint. Thus, the tape is immersed in the solution and becomes flush with the surface.
• Everything is thoroughly smeared. Check the level.
• When the layer dries, use sandpaper.

On a note! Working with reinforcing paper products is somewhat different. It's cut right away the right size and pour boiling water over it. Then apply a layer of mortar to the seam. After waiting for it to dry, it is sanded. Then wring out the tape and apply PVA glue to the seam. When gluing the tape to the joint, it is immediately lubricated with the same glue. The surface is smoothed with a spatula. The seam is very thin and strong. The whole process can be easily done with your own hands.

There is another way, it is similar to the one already given. But to seal the joints, you will need a little skill in handling the tool. It goes like this:

• The solution is quickly spread with a medium spatula. At the same time, without smoothing or removing excess.
• Then they take a wide tool, place it at an acute angle, and move it across the surface from bottom to top.
• It will be correct to press down on him.
• It turns out that the putty fills empty areas and forms smooth surface, onto which the reinforcing product is already glued.

Corners are sealed in a similar way.

The result will be the surface that remains to be covered finishing layer putties. If everything is done correctly, there will be no cracks. In any case, the main thing is to do everything carefully and painstakingly, especially if such work has not been done with your own hands before.

When making renovations indoors, it is important to choose the right one inexpensive material and use it correctly. Craftsmen often use plasterboard to decorate walls. Unlike other materials, its installation will not take much time, and it itself can have any shape.

People who have never done repair work will be pleased by the fact that installing drywall is not as difficult as it seems at first glance: you can handle it even without experience. We understand the intricacies of sealing drywall seams.

Peculiarities

By doing installation work When installing drywall, there will be seams in any case. Their width depends on many factors. You even have to take into account how plasterboard sheets will change under the influence temperature regime. To prevent the seams from being noticeable, they must be sealed with putty..

If the work is done incorrectly, after a certain period of time, marks may appear on the seams between the drywall. small cracks. If you skip this step, the surface will turn out uneven, and the sheets will deteriorate in the future. They will be exposed high humidity and stand the test of time. After drywall sheets are covered with paint or other materials, stains may appear near the seams or the wallpaper may swell.

What to seal it with?

To seal holes between sheets of drywall, you need to choose high-quality putty and the tools that will be used to apply it. First you need to choose a spatula. It’s worth choosing the one that is easiest to work with. The choice depends on the master.

Both a narrow and a wide spatula are suitable for working with putty (the main thing is that its blade is flexible enough). You can check this by simultaneously bending the blade and handle. They should not break or crack.

In addition to the spatula, you may need:

• paint brush;
• sandpaper;
• Sander;
• a drill with a special “mixer” attachment for preparing the mixture.

The choice of putty plays an important role. It depends on what the further decoration of the walls will be. On modern construction market there are many varieties presented of this material, among which you can buy cheap and expensive raw materials, differing in purpose and quality.

If the walls are simply painted, you need to use a simple putty for the seams. It will be enough to ensure that the walls are of high quality and visually attractive. If the walls are being prepared for wallpapering, any starting or finishing mixture will do. It doesn't have to be expensive.

You can take a simple one gypsum base from quality manufacturer. The main component of such plaster is gypsum, which allows the walls to breathe.

The only drawback of gypsum putty is the fact that it sets quickly. Because of this, you have to work quickly, having time to apply a new layer.

To work with seams, you may need paper tapes, sickle tapes or reinforced mesh, with the help of which it is easier to glue transverse as well as longitudinal seams. Paper tape with a groove in the middle will make it easier to work with the inner corners of the seams.

To prevent bubbles from forming under the paper layer, you need to purchase a special tape with micro-perforation. Serpyanka tape is often used for longitudinal joints.

It stretches well, but in terms of strength it cannot be compared with adhesive tape. Although it has an advantage: it is easy to glue. If the master makes a mistake, it can be easily peeled off without leaving visible marks on the surface.

To work, you need to purchase a high-quality primer that will strengthen the surface and also prevent moisture from getting into the connectors between the joints.

Process technology

The process of sealing drywall joints can be divided into several stages, which even a novice master can handle. It is important for inexperienced repairmen to remember to adhere to the rules. This is special important point, since even minor violations can lead to bad result. There is no need to rush, it is important to do everything step by step.

Preparation of materials

No process can be completed without careful preparation. This also applies to sealing seams. Initially, you need to know what the joints between plasterboard sheets should be. The gap can be left small (approximately 1 - 2 mm). This is enough to ensure that the surface does not further deform during shrinkage of the structure. In this case, only the seam will crack, and the sheets themselves will remain intact. On end gypsum boards, the gap must be made larger, expanding the distance between the sheets to 2 mm.

Next, you need to clean the surface of the drywall from dust and cut off all the irregularities with a special knife. You can wipe the surface with a sponge or cleaning cloth. This will take a little time. Then you will need to check the screw heads. This must be done so that when working with putty you do not get dirty when the spatula bounces on the screw. To do this, you need to run your hand over the attachment points. Protruding caps must be tightened using a screwdriver or screwdriver.

Then you need to apply a layer of strengthening primer. If it is a concentrate, it is worth diluting it with water in accordance with the proportions indicated on the package. You just need to mix the finished primer, after which you can immediately cover the seams with it. Apply it at a distance of no more than 15 cm from the joint.

The treated area is clearly visible on the drywall, so the process is perfectly controlled.

Sealing seams

Having prepared all surfaces, as well as purchasing necessary materials and tools, you can start sealing the cracks. Previously, this process was very labor-intensive; it was necessary to apply the solution and embed the sickle tape in it. With the development of technology and the emergence of new building materials the situation changed in better side. Now the serpyanka has a self-adhesive layer: this is already enough to significantly simplify the work.

The edge of the tape is easy to pick up and peel off. At this stage, you cannot rush, so as not to ruin all the work. You need to slowly unscrew the layer of tape, pressing it against the joints of the drywall or the opening between the sheet and the floor. When finished, just cut the tape with a special knife.

After finishing work with the tape, you need to prepare the putty using a drill with a special attachment. The consistency of the solution should resemble thick sour cream. Next, using a spatula, fill the entire space of the seams between the gypsum board sheets. Moving the spatula across the joint, you need to cover the seam, while pressing the solution into it. All this is repeated until all the suture grooves are filled. To level the plane of the joints with the chamfer, putty is applied in a strip of 150 mm on each side.

To strengthen the corners, you need to use a sickle mesh, the width of which is 100 mm. This will prevent cracks from appearing in the most difficult areas. To ensure that working with corners does not take a lot of time, and the result is perfect, it is necessary to carry out the work using an angle spatula. Cutting off a piece of mesh required length, you need to fold it in half and attach it to the corner, then apply the solution to both sides and stretch it with a spatula. In this way they close up and internal corners at the ceiling. For sealing external ones they use metal corners, secured with self-tapping screws.

When the surface is completely dry, it needs to be leveled using sandpaper. or special grinder. If after sanding unevenness is noticeable, more thorough surface treatment, including leveling, is necessary. This process is repeated until all problem areas will not disappear from sight. The drywall is then primed using special composition deep penetration.

After the primer has dried, the plasterboard base can be considered ready for wallpapering or painting.

Having studied all the stages of sealing seams, you can do them yourself. You should not rely solely on your own strengths and do everything at random. When sealing seams, you need to listen to the advice of experts. No matter how well all the work is done, problems may arise due to high load on the walls or sudden changes in weather. There is no need to worry about this.

However, to prevent this from happening, it is necessary to remember that When the temperature changes, any material can deform. In the case of drywall, this leads to cracks. Therefore, you need to fill the seams as carefully as possible. The end joints must be chamfered: this will better strengthen the plasterboard structure.

Priming must be carried out using an acrylic mixture (required for interior work), since the façade primer has a lot harmful substances. Its layer contains antifungal components. They save the walls from the appearance of fungus or mold in the room. It is recommended to use a composition with greater penetrating ability. When this product dries, it forms on the surface crystal lattice, due to which the subsequent layer of material applied to the drywall will adhere well to the base.

Drywall seams at the final stage of installation require finishing so that the surface becomes smooth and neat. But what other tricks and secrets does it hide? this technology? In the article we will tell you why, how to properly, and what means are best to seal the seams, and whether it is possible to do without this procedure.

Joints formed during installation of gypsum boards

No matter how correctly the frame for drywall is made, a seam remains between two adjacent sheets. The size of the joints depends on the characteristics of the material itself, which has different kinds edges During installation, these edges create visible indentations on the surface, which can only be removed during the finishing process.

Uneven seams are formed if the frame is not rigid enough or few profiles are taken for its construction - under the weight of the gypsum board these metal constructions are deformed, causing the edges of the slabs to stick out unevenly. Another factor in the formation of seams is loss linear dimensions gypsum board sheets as a result of temperature changes. Microshifts of the sheets in this case lead to the formation of cracks.

If you do not seal such seams, then:

• it will not be possible to achieve a flat surface;
• the material will deteriorate, because the edges will be exposed to direct influence of environmental factors (get wet, dry out, etc.);
• When painting or wallpapering, stains will appear on the surface and the finish will move away from the surface.

What products will help hide joining seams?

To finish the seams you will need the following materials:

• Perforated paper or reinforcing serpyanka tape for reliable fastening of drywall seams. It is able to withstand high tensile loads, protects sheet joints from the appearance of cracks during microshears, and is used to ensure adhesion between the putty layer and gypsum board.

Serpyanka ribbon

• Putty is one of the most important components in this chain with which seams are sealed. The highest quality compositions - Uniflot or Fugen (Knauf brands) - are easy to apply, do not shrink and do not crack over time, provide low consumption, high strength, and a smooth hard surface.
• The primer is used to protect the material from mold and mildew, to increase resistance to moisture, to ensure adhesion of the finishing layer to plasterboard sheets and to reduce material costs. Apply the primer in two layers, it is preferable to use an acrylic mixture of the Knauf, Belinka, LNPP brands.
• The plaster serves as a finishing coating, creates a smooth surface, protects the gypsum board and increases its adhesion to the subsequent applied layer.

Most Popular plaster mixture– Rotband (Knauf, Germany). Its advantages are a wide range of surfaces to be treated and fast drying time (from 25 to 45 minutes). Plaster is made on the basis of gypsum, so it allows the walls to breathe. Moisture resistant. Used as finishing decorative covering or serves as a layer between gypsum board and wallpaper, paint or tiles.

The main feature when working with Rotband is that the composition must be applied quickly or diluted in small portions, since the mixture sets quickly.

Finishing materials produced by Knauf

How seam finishing technology works: practical tips

Finishing stages:

• the surface of the plasterboard is cleaned of dust and dirt (with a vacuum cleaner or a dry cloth);
• run your hand along the surface of the sheet - if the heads of the screws are touched, they need to be tightened;
• a chamfer is cut from gypsum board sheets at an angle of 45 degrees, with a width and depth of no more than 5 mm, so that the plasterboard sheets do not cling to the edges in the event of micro-shear and chips do not appear;
• then the surface of the gypsum board is coated with the first layer of primer;
• dilute the putty, apply perpendicular movements to the seam at the joints, pressing inward;
• let the putty set (but not dry), apply reinforcing or paper tape to the seam, press it - it should immediately stick to the solution;
• another layer of putty is applied over the tape, carefully leveling, but so that the tape is not visible, the mixture is pulled out and leveled until the surface becomes even;
• The joint between the wall and the gypsum board is sealed in the same way, only the tape is folded in the corner so that it folds in half;
• screw caps are puttied;
• after the putty has completely dried, carefully sand the seams;
• after sanding, apply a second layer of primer;
• when there's nothing left on the wall dark spots from the primer mixture, the surface of the sheet is covered with Rotband, carefully leveling.

Room ready for final plastering

After this stage finishing GKL sheets are considered completed. It is not necessary to additionally treat the layer of plaster; you can use it as a front covering or decorate it with tiles, wallpaper, or tinting. You will see how all the stages of finishing take place, from puttying the seams to applying the decorative layer, in the video below.

Finally

In the end, we’ll tell you about the little helpers in this matter: a spatula, a brush or a roller. You will need two types of spatula: one narrow (100 mm) - designed specifically for sealing seams, the second wide (250 mm) - for rubbing putty and plaster over the surface of the sheet.
