Than to seal a seam on a ceiling between plates? Instruction, technology

If you at least once carried out repairs in an apartment or a house, you know that it should start from the ceiling. On the rough surface, you will see cracks that appear at the joints of the floors. Even if the surface is whitened, the cracks will appear again, which will raise the issue of sealing seams between the plates.

Preparation of tools and materials

If you are thinking about the question of how to seal a seam on the ceiling between the plates, you should prepare tools and materials, among them:

• Putty;
• putty knife;
• A blade for a drill;
• Painting tape;
• Fine-grained nazhdachka;
• Gun for sealant ;
• primer;
• Perforator;
• mixer;
• PVA glue;
• Acrylic sealant.

As a putty, you can use a dry gypsum mixture, but when choosing a primer, you need to prefer one that has a deep penetration. The spatula should have an elastic flexible blade, while the puncher can be replaced with a drill. But it will need a nozzle in the form of a shovel. If you could not find the sandpaper, you can use a grinding screen.

Recommendations for the selection of materials

Before you, sooner or later, too, there may be a question about how to seal a seam on the ceiling between the plates. The technology of work is described in the article, but in order to achieve a qualitative result, it is necessary to select the right materials.

In the store you should buy cement NC, used to fill deep seams. This material has expansion properties when solidified, so it fills the entire space of joints and seams. You will also need dense thermal insulation materials, which are necessary for sealing wide joints. It is better to buy those that are made of foam polyethylene or polyurethane.

Experts advise to use also elastic shpaklevku. When buying a grid-serpants, it is necessary to take into account that its width should extend beyond both sides by 50 mm. For final works, you will need a primary and final putty, which will have to finish the entire area of the ceiling.

How and what to seal the seam

If you are faced with the question of what to seal the seam on the ceiling between the plates, you must decide on the order of the work. These manipulations can be considered quite laborious, haste in this matter will be a hindrance. First, the seam is expanded, use a drill or perforator for this, the tool should be supplemented with a blade attachment.

Remains of cement screed are removed with a spatula or knife. If this step is neglected, the fresh solution will not adhere well to the surface. The resulting slit should be cleaned of dust, spread its surface with a primer applied by an abundant layer. The layers should be allowed to dry. Gypsum plaster is mixed with a construction mixer. If the composition is needed very little, then you can do without a mixer.

The solution should have a consistency of thick sour cream. The crack is filled with plaster, and furrows should be decorated in several approaches. Each previous layer must be dried before laying the next one. If you are thinking about how to seal a seam on the ceiling between the plates, then you can use a mounting foam. It is used when the seams are particularly deep. Remains of the material after drying are cut off with a knife, the surface is leveled, and plaster should be rubbed into the pores of the foam.

Final work

After all the above steps, the layer should be allowed to dry out. Only after you can begin to strengthen the painting tape. Its width should be greater by 3 cm in relation to the seam.

Apply tape to the top of the tape. These layers must be completely dry. The surface of the plates is primed and the final putty is carried out . Its carrying is carried out in a thin layer. In return, you can use a fiberglass cloth, which is primed and painted in the desired color.

Alternative material options

Quite often novice masters think about how to seal a seam on the ceiling between the plates. Instead of foam, glue is sometimes used for laying ceramic tiles. The paint net can be replaced with a regular bandage or gauze.

Suitable and thin fabric, which must be soaked in water and steam off with an iron, so as not to encounter shrinkage. In order to facilitate the work, the ceiling is peeled off with polystyrene tiles, which has no seams. Small gaps can be covered with acrylic sealant. Silicone sealant should not be purchased, because it does not retain paint.

Another solution is the simultaneous formation and subsequent filling of cracks. First, a thick cement slurry is prepared, to which liquid glass is added. Bint dipped in this composition, folded in the form of a bundle and laid in a slot. Work is necessary quickly, because the solution with glass will dry in a short time.

The same composition can even out the ceiling, and after drying, treat it with sandpaper. When deciding on how and what to seal a seam on the ceiling between the plates, you must be careful, because in the floors there can be wiring, which should be protected from damage.

Recommendations of specialists on the work

Many people are interested in knowing how to seal a seam on the ceiling between the plates, the instructions below will help you with this. Before cleaning, the surface should be treated with water from a spray gun. It is better to wet only that part of the ceiling, over which you plan to work at the moment.

The moistened area is left for 15 minutes, and afterwards you can get rid of the old cover and move on to the next section. The whole procedure in the new zone is repeated again.

As soon as you can get rid of the old cover, you will be able to estimate the volume of the forthcoming works. As a rule, there are several joints per room, the number of which sometimes reaches three.

Thinking over the question of how to seal a seam on the ceiling between the plates, the options presented above should be considered. At the stage of preparation, the seam should be cleaned up by 50 mm. Further, using a wide brush or iron brush, the seam is cleaned of fine concrete residues.

To seal the seam, you can use special rollers made of foamed polyethylene. It is important to choose products of the required thickness. A strip of sealant is applied to one side of it. After the roller can be filled into the primed joint. Use a spatula for this. The master should take care that there is room for filling the space with concrete.

When sealing joints with expanding concrete, it is necessary to place grooves for decorative plaster. Once the solution has dried, and the groove is prepared, an elastic filler can be applied to the surface. Work should be carried out with the help of two spatulas, one of them should be wide, the other - medium or narrow.

Methods of work

On a wide tool, a composition is drawn from the container, and a narrow tool is needed to apply the putty to the joint. The solution is sealed in the seam and leveled to the level of the ceiling surface. From surplus putty should be disposed of. After 2 days, which are necessary to dry the mixture, you can begin to reinforce the seam. For this, a thin layer of putty is applied to the surface, on which the mesh is strengthened. It should be squeezed into the solution and remove the excess with a spatula.

The application of the primer after drying of the joints is carried out using a roller. It is better to apply it in two layers.

After the ceiling has dried, plastering can begin. First, a thin layer is applied, and after it has dried, you can lay the finishing coat, which should be smooth. Use when using a spatula, leveling the surface to an ideal condition.

Filling the hole in the seam

Now you know what to seal the seam on the ceiling between the plates. We hide the seams together with the holes in them. You can act in this case in one of two ways. The inner part of the hole is closed, which can be done with a narrow brush. The inner walls are cleaned of dirt, sprinkled with a primer.

As soon as the first layer dries, you can start applying the second one. Thinking about the question of how to seal a seam on the ceiling between the plates, you need to read the tips. Of these, you can find out that the seams, like the holes, are filled with mounting foam. After it dries and extends, the excess should be cut off, in the inner space of the hole you need to cut out a cone, whose height is 50 mm. These manipulations are necessary for laying the cement slurry.

Conclusion

Many novice home masters are thinking about the question of how to seal a seam on the ceiling between the plates, so that the particles of cement do not fall out. As in the case of slots, the holes must be finished with putty, on the layer of which is attached a sickle. It should be well leveled and left to dry. For filling large holes, you can use plywood or trim laminate. The dimensions of the sheet must be greater than the dimensions of the hole by 100 mm.
