The height of the metal guides, from which the crate is assembled under gypsum board, varies between 40 and 60 mm. Plus - the thickness of the fixed sheets. For rooms with a relatively modest size, the total reduction in useful area can be quite appreciable. Frameless technology for finishing walls with plasterboard is much easier to implement, practically does not affect the square of the room and allows you to use thinner( and therefore cheaper) GCR.
The reader will be able to learn about all the variants and features of the techniques( and several of them) of gypsum wall finishing without mounting the base frame and profile from this article.
Preparatory activities of
Given that many readers are engaged in repairs in the apartment( house) is not the first time, the author considers it necessary to limit himself to only listing all the necessary measures that are taken when preparing the walls for decoration. Do or skip a stage, everyone will decide independently, depending on the material of the basis, the degree of its deterioration, the specifics of the operation of the room and a number of other factors.
Cleaning the
Wall The main task is to inspect the base and evaluate its technical condition. Drywall, whatever category it is( even moisture resistant), by definition absorbs moisture. The difference is only in the intensity of this process. Any gap( crack, split joint) is a "loophole" for the penetration of liquid into the structure. It is not necessary to rely on the outer lining, since it can not completely eliminate the condensation effect under the skin.
What to take into account - in the houses of the panel, some utility rooms have rounded corners. It depends on the technology of manufacturing individual blocks-cabins( for example, a bathroom).Since the gypsum board has the correct geometry and does not bend, it is necessary to make a sample of material in the joints of adjacent walls. In other words, give the corners the right shape. Than - it's easy to solve. For example, an el / drill or a perforator( with a suitable headpiece), a "Bulgarian".Perhaps, it will be enough and the traditional chisel set + hammer. It is possible to do easier - to bend drywall.
Wall treatment
The choice of means( fire retardants, antiseptics) depends on the base material. But at the final stage, after the preparations dry out, the soil must be applied. The point is that the fixing of the sheets is done with the help of a mounting glue. The priming composition sharply increases the adhesion of the surface and contributes to a more reliable fixing of the drywall.
Layout
With the correct approach to the organization of work, this is done in advance, according to the old cladding. For what? To determine the parameters of the sheets and buy GCR of such sizes that as little as possible to deal with their cutting. This will save both time and money.
But after the treatment of the walls, a new "grid" should be applied. This will allow the plasterboard to be laid exactly in place, eliminates the possibility of horizontal displacement of the sheets and simplifies the entire finishing process. In addition, it is necessary to designate the lower level, even if the gypsum board is mounted to the floor. It can also have irregularities, and if you focus only on the coating, then the distortions of the sheets of drywall can not be avoided.
The procedure for finishing the walls with gypsum plasterboard
Cutting the sheets of
There is nothing complicated here, since all segments are already marked on the wall with a grid, and it remains only for the individual to cut out a couple of fragments from the GCR.
Features of the
drywall fastening technology. Unevenness( height difference on the wall being cut) is denoted by Δ h.
- Adhesive for plasterboard finishing is used special, on gypsum basis. One of its features - fast hardening. Therefore, it should be planted in such a volume to use immediately.
- Holes( slots, slots) for communications coming out of the walls( for example, electrical wiring) or passing through them( cable, pipes) in the plasterboard are cut out in advance.
After pressing the GCR to the wall, it is necessary to achieve its full abutment. This is done, for example, by tapping the entire area of the sample with a rubber hammer. Another way is to press the flat rod and move it from top to bottom or from left to right( depending on the spatial orientation of the GCR).
The foundation is almost level( Δ h & lt; 5 mm)
The back of the gypsum board is coated with a thin layer of glue, which is additionally leveled with a spatula( toothed), after which GKL fixes on the wall.
Minor unevenness( Δ h within 5 - 15 mm)
In this case, the reverse side of the sheet is covered with glue "cakes".In the process of pressing, the surplus of the composition will fill the existing voids, which will ensure better fixing of the drywall on the base.
Significant height differences( Δ h from 15 to 30 mm)
With such unevenness of the wall, it is necessary to exclude possible extrusion of plasterboard in areas where there are notches( depressions).In practice, one of the two options for attaching sheets is realized. Choose the most appropriate way for local conditions.
In places of notches are pasted pieces of plasterboard( "beacon"), cut to the appropriate size and with the required configuration. This preliminary leveling, as a rule, is sufficient to ensure that the sheet, after fixing it, is snug against the wall all over the area.
At the deepest point of the hollow, a hole is drilled, the dowel is pounded, after which a fastener with a large bonnet is installed in it. By adjusting its height, you can bring the top of the part to the level of the wall plane. After fixing gypsum cardboard, its punching in this place will be ruled out.
Finishing of the wall
Cleaning of the joints
During transport, installation of drywall, the edges of the sheets can be somewhat deformed. Therefore, the lines of their joint should also be aligned. Skin - the most suitable for this "tool".The task is to remove excess material and achieve a perfectly smooth surface along the entire seam.
Tapes sticker
It is better known as "serpian".Simultaneously, the joint closes and reinforces the joint. In addition, paint can be applied from above.
Further design of the wall - at the discretion of the owners( coloring, wallpaper stickers and so on).
