The final stage when working with drywall is sealing the seams. Although this process is not complicated, it should be taken seriously. Otherwise, after some time, cracks will appear on the finished surface. We will now talk about how and with what to seal the seams in drywall.
In order for the sealing of drywall seams to be done efficiently, a number of requirements must be met. In particular, special attention paid to the temperature and humidity conditions in the room:
- the minimum temperature should be +10ºС;
- there should be no drafts;
- for 3-4 days after the repair, the temperature should be approximately the same;
- Sealing of joints is carried out after all plastering and concrete work has been completed.
The entire plastered surface must dry. Availability high humidity indoors will complicate the process of normal hardening of the putty. And this will lead to deformation of the seams.
Before sealing the seams between sheets of drywall, you need to check that the material is correctly fastened in all areas. If the drywall is poorly fixed, this can lead to rapid destruction of the putty at the joints of the sheets.
All self-tapping screws must be embedded in the drywall. Their heads should not protrude above the surface of the material, as they will interfere with the finishing.
Sealing materials
Now let's talk about how to putty drywall seams. To complete this work we will need two basic materials:
- paper reinforcing tape;
- putty.
Sealing tape
Paper tape for drywall seams is the most the best option for sealing joints. Sheetrock Joint Paper Tape is in high demand. The standard dimensions of one roll are:
- length - 76 m;
- width - 5.25 cm.
Sheetrock Joint Paper Tape has the following characteristics:
- increased strength;
- does not stretch;
- fits without folds;
- the possibility of centered folding, which simplifies the finishing of corners;
- strong connection of plasterboard sheets;
- maximum prevention of ruptures.
Due to the fact that Sheetrock Joint Paper Tape is very thin, it can be fixed using regular putty. Moreover, joints can be sealed without chamfering horizontal seams, and sheets can be mounted end-to-end.
Putty for sealing
Putty for drywall joints can also be used in finished form. But it is best to purchase a dry mixture, since it can be stored longer. And the cost of dry putty is much lower. In terms of quality, it is no different from ready-made mixtures.
The only caveat is the mandatory adherence to the solution manufacturing technology. To do this, you should strictly follow the instructions, which are always included with branded products.
The basis for the manufacture of putty is one of three components:
- cement;
- gypsum;
- polymers.
Cement putty is resistant to moisture. But sometimes the surface finished with this material becomes covered with microcracks.
Putty, which is based on gypsum, is very susceptible to changes in moisture. Not used in rooms with high humidity.
The best material is polymer putty, which has absorbed best characteristics cement and gypsum putties.
Among the variety of compositions, the most suitable options for puttying joints between drywall are products from the Knauf company:
- Fugenfüller GW;
- Fugenfüller hydro (the seams of moisture-resistant drywall are sealed);
- Uniflott.
Putty Knauf-Uniflott - quite expensive pleasure. But the result will not keep you waiting. In terms of strength indicators, this material is significantly superior to similar products.
If you plan to carry out puttying work immediately, then it is better to use a ready-made mixture. Best option- Sheetrock putty.
Joining seams
Drywall sheets are available with various longitudinal edges. The most acceptable solution is to use material with edges that have a semicircular thinning. Thanks to this edge, the sheet comes into maximum contact with the putty, and the result is an ideal surface.
The process of jointing drywall joints consists of the following main steps:
- surface preparation;
- applying the first layer of putty;
- laying reinforcing tape;
- applying the finishing layer of putty;
- surface grinding.
Surface preparation involves removing dust. The putty should stick to the surface without any problems. Dust is removed using a wet cloth.
Filling the joints with putty is done with a spatula. The mixture is applied in a transverse direction from the seam. The procedure is carried out along the entire length of the joint. Excess putty may be present only in the extreme part of the seam.
The Sheetrock reinforcing tape is laid in such a way that a layer of 0.5-0.7 mm of putty remains underneath it. To facilitate the process of laying the tape, it is necessary to dilute the prepared putty with a small amount of water.
The tape is embedded in the putty along the entire seam. Central part The inner fold of the tape is placed in the center of the joint between the sheets of drywall. This work is carried out using a spatula, by pressing the sharp corner of which excess solution is removed. The tape is completely covered with putty.
After the tape has dried, a second layer of putty is applied. Horizontal joints are covered with a thicker layer of material. The second layer of putty should also dry. After which you can sand the seams with sandpaper.
Video about sealing drywall seams:
When making renovations indoors, it is important to choose the right 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
When performing installation work on 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 small cracks may appear at the seams between the drywall. If you skip this step, the surface will turn out uneven, and the sheets will deteriorate in the future. They will be exposed to 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;
- grinding machine;
- a drill with a special “mixer” attachment for preparing the mixture.
Quite a lot important role The choice of putty plays a 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 gypsum base from a 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, which make it easier to glue transverse and 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 poor results. 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. Having cut a piece of mesh to the 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, the internal corners of the ceiling are also sealed. To seal external ones, use metal corners secured with self-tapping screws.
When the surface is completely dry, it needs to be leveled using sandpaper. or a special grinding machine. If after sanding unevenness is noticeable, more thorough surface treatment, including leveling, is necessary. This process is repeated until all problem areas are out of 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.
After installing drywall sheets, you do not get a completely flat and smooth surface. The fact is that the sheets are joined during installation, and these joints require additional finishing to make everything even. But it's not just that. Sealing drywall joints helps prevent future cracking. Without such sealing, cracks may appear in the finish coating. Doing the job correctly will save you from a lot of trouble in the future.
This is what a wall with putty joints looks like
Sealing drywall seams with your own hands is done for a number of reasons. Only by understanding why such a procedure is needed will it be possible to perform it correctly. Many people simply mechanically carry out a series of works, without even thinking about the purpose of such actions. In fact, grouting drywall joints is done for a number of reasons:
- in order to protect the finish from cracks. Sealing drywall seams helps create a uniform surface, and this is the type of base that finishing materials should work with;
- for leveling walls. It is clear that the gypsum board is already smooth, but often it is all puttied for future coatings. In this case, preliminary sealing of the seams is necessary;
- to hide gaps due to curved walls. Before sealing seams on drywall, you need to make sure that the material is laid as evenly as possible. But often the sheets are installed crookedly, which causes the formation of large gaps between the joints. They need to be sealed;
- in certain cases, puttying the edges prevents moisture from penetrating into the plaster, which means the sheets do not swell or crumble over time.
We carry out preparatory work
Before sealing drywall joints with mortar, you need to carry out a series of preparatory work. This work includes preparing drywall sheets, selecting working tools and putty.
GKL with a semicircular edge is used as standard
Preparatory work on joints is reduced to chamfering. The chamfer is needed to create a small depression at the joints of the gypsum board. Putty will be placed in this recess, which will make the joint of the sheets stronger and more reliable.
October 22, 2016The drywall sheet already has a factory-made longitudinal edge. There is no need to touch her. An edge is created with a knife only in those places where the gypsum component of the sheet is visible.
Puttying drywall seams with your own hands will require skills in creating an edge. To do this, the edge of the drywall sheet is cut with a wallpaper knife at an angle of 45 degrees, creating a recess. You can also simply remove the chamfer using a special plane at an angle of 22 degrees. Chamfering is carried out before attaching the drywall sheets to the surface. You can trim the edge with a knife when the gypsum board is attached to the surface. The depth and width of the chamfer to be removed should be 5 mm.
You can trim the edge (chamfer) with a knife and a planeTo work you will need the following tools:
- Flexible spatula 8 cm wide.
- Flexible spatula 10 cm wide.
- Rigid spatula 20 cm wide.
- Putty (Knauf Fugenfuller is suitable).
- Reinforcing tape.
- Clean bucket.
- Brush.
Many people wonder how to cover drywall seams? You need to decide this issue for yourself even before sealing the drywall seams begins. Correctly selected putty is the key further success work. Typically, Knauf putty is used. Traditionally, the cheap and easy-to-use Fugenfuller is chosen. Sometimes Uniflot takes its place. You can choose something else if the future finishing coating requires it.
Priming the seams and mixing the solution
It is not enough to know how to putty drywall joints, because the primer also plays an important role. Deep penetration primer is used to clean the surface, as well as for better adhesion. Using a brush, all joints are coated with primer, and it does not matter what kind of edge they have (factory or homemade). The soil will serve as a connecting link, a kind of glue, between the drywall and putty. You need to wait until the primer dries completely.
A roller is not suitable for priming joints, as it will not be able to penetrate into the cracks between the sheets of drywall.
Properly mixed putty will be the key to successful work. Fugenfuller is a popular drywall joint compound. However, not everyone chooses it because it dries quickly. Although this statement is doubtful, because you need to be able to mix the solution. First, you need to mix the solution in small portions, calculating your strength. Secondly, if everything is done correctly, the putty will not dry out within 30-45 minutes. And this is quite enough for comfortable work.
It is collected in a clean bucket required quantity water (you need to look at the putty instructions) and then the finishing putty is added there. It should be poured in as if it were flour. If you throw everything into a pile, then problematic lumps are guaranteed. Many people argue about the best way to seal drywall joints without thinking about how they make this mixture.
In the process of creating a mixture for sealing jointsAfter the putty is carefully poured into a container of water, it is mixed with a spatula. Using a mixer will cause the mixture to harden faster. Fugenfuller needs to be mixed a little so that all the putty is wetted, and then left to swell for 5-10 minutes. After this, the putty for sealing drywall joints is thoroughly mixed with a spatula, and all lumps are broken up. The final mass should look like very thick sour cream. With the finished mixture you need to start working immediately.
Sealing technology
Drywall seams are sealed using different spatulas. Typically, the mixture is scooped up with one spatula and applied to another. Or you can put it on one spatula and hold it in your hand. Using the second spatula, the putty is taken from the first as needed. This scheme allows you to work faster, without being distracted by constantly collecting solution from a bucket.
Do-it-yourself puttying of drywall joints begins with filling the void between them. Many people like to work for a quick fix, applying serpyanka or paper tape to the seams, and a layer of putty on top. Although this technology speeds up work, it is fraught with consequences.
If thin-layer textured plaster is eventually applied to such a surface, then over time it will simply crack at the seams where voids remain. Also, with this method, problems may arise when cutting wallpaper in the corners, when the pressure can cause the knife to fall into the void.
The first job you will need is a 20 cm spatula. It is used because the seams between sheets of drywall need to be sealed as quickly as possible. A sufficient amount of solution is poured onto its surface to fill the voids between the joints. Using a tool, apply the mixture across the seams, trying to push it into the joints as much as possible.
Sealing drywall seams along factory edges and hand-made chamfersIt is necessary to completely fill the joints between the cut edge and the factory edge. In this case, you should not leave sagging on the drywall. It should remain level. After this, you can seal all the screw heads with putty, but you still need to give the solution time to dry. The putty will retract a little and then a hollow may even form at the place of the seams.
This technology is used by those who want to know how to properly seal seams in drywall. If you do not fill the voids with putty, but immediately apply the solution and then the reinforcing tape, then tubercles may eventually form at the joints. Therefore, the voids are first filled with putty, and then paper tape or sickle is applied.
Using reinforcing tape
For many, filling drywall seams using perforated paper tape is unacceptable. Like, it warps a lot, and the joints turn out crooked. To avoid this, the tape is immersed in water for a while. Then it is taken out, excess water is removed and the joints are glued. Gluing begins with the cut seam.
Everyone decides for themselves whether to use paper tape or a special mesh. Who is comfortable with what and who is used to working with what. In any case, there is no need to immediately try to seal sections longer than 2.5 meters. This is very inconvenient and difficult.
Many people are interested in the question of how to putty drywall seams with tape. Its use is a direct continuation of the above-described technology of filling joints with putty. When the solution dries, the seam will need to be covered again with a layer of putty. For this, a 20-centimeter spatula is used, onto which the solution is applied with a 10-centimeter spatula.
The tape fits as tightly as possible to the drywallSealing drywall seams with reinforcing tape will help make the joints more durable. To do this, apply tape to the newly applied putty exactly in the center of the joint. It is pressed against the drywall with an 8 cm spatula. It is with this spatula that it is best to squeeze out the solution from under the tape. Also, such extrusion will straighten the tape if it has formed a wave somewhere. For this reason, gluing drywall seams begins from the corner. The protruding putty is stretched in all directions using a wide spatula. But puttying the drywall joints is not finished yet.
There should be no hills after drying.The tape is attached to the drywall, but still needs to be covered with a layer of putty. This is the final finish of the reinforcing tape. The putty is spread in a thin layer over the joint covered with tape. If everything is done correctly, then no bumps will appear at the work site.
Specialization: master in the construction of plasterboard structures, finishing works and styling floor coverings. Installation of door and window units, finishing of facades, installation of electrical, plumbing and heating - I can give detailed advice on all types of work.
Today I will tell you how to seal drywall seams with your own hands - this process is not difficult, but any violation of the technology leads to disastrous results. You need to thoroughly understand the work before you begin, this is the only way you can be sure that the finish will be reliable and durable. For simplicity, I have divided all the work into 3 stages, you just need to follow all the recommendations below.
Workflow Description
Let's begin to understand the specific actions that need to be performed in order for the result of the work to be the best. It is important to do everything in the right sequence and not to rush - rushing is unacceptable, especially if you have little experience.
Moreover, all problems in the form of cracks most often appear precisely because of haste, although the quality of materials is of great importance.
Stage one - preliminary activities and purchasing everything you need
No serious work is carried out without preliminary preparation. Sealing gypsum board joints is no exception; in this case, preparation is of fundamental importance. First of all, you need to figure out how to join plasterboard sheets.
Very often I am asked the question, is it necessary to leave a gap between the sheets? There is a lot of information on the Internet, but it is often contradictory and ambiguous; I have researched hundreds in my time square meters walls and ceilings, so I can be guided own experience and give advice from practice, and not from articles and reviews.
So, between the sheets you need to leave a small gap of 1-2 mm, this allows you to eliminate surface deformation when moving building elements; in the worst case, your putty will crack, but the sheets will remain intact.
You also need to immediately clarify how to join plasterboard sheets at the end and cut ends of the material. Here you should maintain a gap of 2 mm and additionally prepare the connection for putty, but I’ll talk about this a little later.
Now let’s look at what needs to be purchased to carry out the work; the list of materials and tools is small, so understanding it won’t be difficult:
Materials | Description |
Putty composition | First of all, you need to figure out how to putty the drywall joints. Personally, I use a proven composition from the Knauf brand called “Fugen”, it is ideal for sealing joints on gypsum boards and using a sickle mesh, but it can be used to putty completely on surfaces, that is, the mixture will definitely not be wasted. The advantage is the absence of shrinkage and high resistance to cracks; the price for a bag weighing 25 kg is approximately 400-450 rubles |
Serpyanka mesh | With its help, we will strengthen all joints and significantly increase their resistance to cracking. The mesh is most often sold in two widths: 45-50 and 100 mm, I use the first type in buildings made of brick and concrete, and the second in houses made of wood, since it “walks” more and needs to be strengthened more thoroughly. I recommend using self-adhesive serpyanka, it is much more convenient to use, a roll 90 meters long costs about 100 rubles |
Primer | The primer allows you to strengthen the base and improve the adhesion of the putty to the surface; in addition, it creates an additional barrier to moisture penetration, which prevents the finish from peeling off in the future. I use acrylic strengthening compounds; a container of 5 liters of ready-to-use primer will cost you 200-300 rubles |
Spatulas | It is impossible to apply a primer without a good spatula; for sealing joints it is best to use a wide version of 250-350 mm, and to apply the mixture and distribute it you need a narrow one hundred millimeter spatula. When choosing, be sure to check whether the tool is level; I usually go through 5-6 products until I find a normal one, especially if we're talking about about inexpensive spatulas |
Additional tool | This should include all other necessary equipment: from a construction knife for cutting chamfers to a brush or roller for applying primer and a screwdriver for tightening screws. The easiest way to prepare the mixture is with a drill with a mixer attachment; wide, capacious containers are well suited for the work, but in as a last resort, you can get by with a regular bucket |
The putty should be produced no more than 3-4 months ago, in addition, buy it only where it is stored in a heated warehouse. Violation of storage conditions reduces the quality of the composition, and very significantly.
Stage two - preparatory activities
If everything you need is at hand and the drywall is fixed to the frame or glued to the surface (by the way, you can glue it with the same “Fugen”), then you can begin the preparatory work.
The workflow looks like this:
- First of all, it is worth clearing the surface of dust; if there are burrs or burrs at the joints, they should be carefully cut off with a construction tool; there should be no protrusions or other flaws. You can wipe it with an ordinary rag, most often there is little dust, but if the walls have been standing for some time, then they definitely need to be cleaned, especially since it is not difficult and will not take much time and effort;
- Checking the heads of the self-tapping screws is another important step, which for some reason many people skip; as a result, later, when putting putty, the spatula bounces and you have to get dirty in the mixture and tighten the fasteners. But everything can be made simpler: run your hand over the fastening points, if somewhere the screw protrudes above the surface, you will feel it. The cap must be recessed below the level of the drywall using a screwdriver or screwdriver;
- The factory edges of the sheets do not need any additional processing, but if you have joints of straight end sides or cut elements, then they need to be trimmed. A chamfer is made at the connection at an angle of 45 degrees, its width and depth should ultimately be 5 mm, cutting is done using a regular construction knife. To make it clearer to you how to cut seams, below is a photo of the chamfer cutting process;
- Before sealing the seams, it is necessary to apply a strengthening primer to the surface. Everything is very simple here: if you have a concentrate, you need to dilute it with water in the proportions prescribed in the instructions, and if ready-made composition, then it needs to be mixed well, after which it can be applied. The treated areas are clearly visible on the drywall, so you can clearly control the process - the seams are primed 15 cm on both sides of the joint.
Stage three - sealing the seams
Now we will figure out how to properly seal the seams, there is also nothing complicated here, the main thing is to prepare the surface well and use high-quality materials. The workflow looks like this:
- As I said above, the seams need to be puttied with tape, and if earlier it was necessary to apply the composition and embed the serpyanka into it, then nowadays everything is much simpler. The fiberglass mesh has a self-adhesive layer, so you just need to carefully open it and, gradually unscrewing it, press it at the junction of the sheets. At this point, the consideration of how to glue serpyanka can be considered complete - when the joint is glued, the material is cut off with a construction knife;
- Before you putty the joints, you need to prepare the composition. To do this, take a container into which a certain amount of water is poured and the composition is poured; the instructions on the package will tell you all the proportions. Next, you need to stir the ingredients until a uniform mass is obtained; it is better to use a drill, since with it the quality of the mixture will be much higher, and it will be easier for you to carry out the work; the putty should have the consistency of thick sour cream;
- Let's figure out how to seal the joints, for this you need small quantity Apply the putty on a wide spatula; the easiest way to do this is with a narrow spatula. First of all, you need to fill the seam between the sheets, everything is simple: with movements across the joint you need to cover the recess, pressing the mass into it. This primary stage, the purpose of which is to fill all cavities with a composition for maximum strength;
- Now let's look at how to putty the seams correctly; the composition is leveled along the joints so that the seam recess is completely filled. That is why we need a spatula with a width of more than 200 mm. As for direct joints with a cut chamfer, in order to level the plane, the composition is applied wide stripe– 150 mm in each direction, this will level the plane;
- You also need to tell us how to putty the corners. To strengthen them, it is best to stick a 100 mm wide serpyanka mesh; it helps prevent cracking in these difficult areas. In order not to have to worry about drawing straight lines, the easiest way is to purchase a special angled spatula; it is available for both external and external internal corners, with its help you can achieve an ideal work result with minimal time and effort;
Prepare no more than 5 liters of the mixture at a time, as it begins to set after only 30 minutes, and you will have to throw away the putty if you do not have time to use it up.
- After the surface has dried, it must be leveled using a special sanding block and sandpaper or abrasive mesh. Here it is important to make the surface as even as possible; if after finishing sanding you find flaws, you can repair them and level the surface again. Other works follow, but this is a topic for a separate review.
We figured out how and with what to seal the seams on drywall, everything is very simple if you know the technology and use high-quality materials and handy tool. You just need to repeat all the steps to do the job yourself.
Conclusion
Sealing drywall joints – prerequisite high-quality and reliable finishing of wall surfaces and. If you simply putty the bases completely, then the likelihood of cracks at the joints will be many times higher. The video in this article will help you understand the topic even better, and if some points are suddenly unclear, then ask questions in the comments under the review.
