Repair of a wall made of plasterboard: recommendations

When carrying out repairs in a room, it is not uncommonhave to be finished. This facing material is known for its universal properties: it is strong, fire-resistant, has excellent soundproofing properties. The low cost and light weight of this base have elevated it to the rank of the most popular brands of the construction plan. Despite a number of excellent qualities, this material has a fairly fragile base, which can quickly collapse and undergo changes. In this case, it is necessary from plasterboard. It is carried out quite easily, and you can do it yourself.Hole in plasterboardDrywall, unfortunately, is a fragile and weak material, so punching a hole in it is not difficult.

The causes of the appearance of defects on the surface

The main reason for the occurrence of all kinds of defects on the outer layer is the violation of the rules of interaction with the gypsum base and non-compliance with basic standards.

  • Provide inappropriate conditions for storage of material. As a result of a temperature jump and an increase in humidity on the gypsum base, cracks appear quickly, they quickly destroy the surface.
  • GKL sheets should be stored in the factoryon a flat, horizontal surface, in a dry place, at normal humidity. On the eve of the installation work, the material should lie until the state of complete acclimatization of the substrate. Installation is carried out at an air temperature above 10 degrees, humidity must correspond to 60% or less.
  • Scheme for sealing cracks in plasterboard.Plasterboard walls can be significantly damaged due to violations in the installation technology. For example, the use of devices that are not suitable for this material: fasteners, profiles, putty, backfill. Thus, profiles on a metal base must be steel, their thickness must be 0.6 mm. This metal, when in contact with air, must prevent the formation of corrosion on the surface. Reducing such numbers leads to a change in the hardness of the entire structure. For finishing walls with plasterboard, special fasteners are used that do not form rust. Any of the structures is designed to be fixed with a certain element. Failure to comply with distances. An acceptable distance between parts of plasterboard sheets will be 57 mm, and the clearance of the floor and enclosing elements is 10 mm. If you want to hang something on the plasterboard walls, use special dowels. Their sizes should match the thickness of the coating. Light weight loads are hung on gypsum panels using hooks or nails. Massive cabinets or shelves are attached with plastic dowels or screws. Return to contents</a>

    Required tools for installation

    • knife;

    • putty knife;
    • sealant;
    • putty;
    • sandpaper;
    • Oil paint;
    • drywall.

    The length of the knife should be 15-30 cm. Return to contents</a>

    The appearance of cracks at the seams

    Such manifestations are associated with non-compliancetechnologies in the process of sewing the frame with sheets and making mistakes. However, one of the reasons may also be too sharp a temperature drop, for example, in winter. To get rid of this problem, you need to do the following:

  • The boundaries of the crack slightly spread apart in width anddepth, only a few millimeters will suffice. For this, a knife or nail is taken. In this way, the gap is cleared, after which the material will firmly adhere to the base of the gypsum board.
  • Priming the crack.
  • Puttying joints with a special compound. Fill space with such a composition should be tight, taking into account the fact that the filling substance will take a little. To do this, take a small spatula or a construction knife. Excess of putty should be removed.
  • Once the joints have dried, it is ground with a fine sandpaper. If necessary, the substrate is primed and tinted.
  • Before work, you should outline the perimeterblanks for a future patch. When carrying out such repairs, putty can be replaced with acrylic. The method for processing seams will be similar. It is not recommended to use silicone: it has a greasy composition and cannot be painted. If the cracks occupy a large surface of the sheet, the wall is repaired using a fiberglass mesh. It is glued to the entire base of the wall with putty for processing gypsum board seams. The surface is treated with finishing putty. Then, sanding and priming of the damaged surface are carried out. Then small holes are eliminated. A good reason for this type of damage is mechanical impact of household significance. Such a hole is called a dent or hole. In this case, wall repair is associated with cutting off the damaged area, priming and puttying it. Return to the table of contents</a>

    How to get rid of large diameter holes?

    Such repairs take place in the following form:Scheme of patching a hole in a plasterboard wall: 1 - preparing the overlay, 2 - cutting for the overlay, 3 - installing the overlay, 4 - filling.

  • The configuration of the defect is studied. Then, guided by its contours, conduct a rectangular, triangular or round outline. Using this technique will make a template that facilitates further work with the damaged opening.
  • A stencil is made for the hole. It is made in this way: a paper sheet of a given size is applied to the hole to the wall, marking is done, followed by cutting out the part. This template allows you to create a new piece of drywall.
  • From the profile of the CD is taken a small part: its length should be much larger than the width of the hole, the difference is 5-10 cm. If the hole has significant dimensions, several profiles must be taken. They are fixed on the other side of the partition, and screwed with screws from the outside.
  • Once the parts are fixed, you can conductfurther repair. For this, all the walls are cut at an angle of 45 °. Such measures will reliably fix the connection and increase the surface of the connection of putty and GKL sheets.
  • Further, the seam along the entire base is glued with the help of a serpentine tape. Such measures help to prevent the occurrence of new cracking throughout the seam.
  • Once the puttying layer has been dried, after the repair of the site, its grinding and priming is carried out.
  • To minimize the amount of household mechanical impacts on plasterboard sheets, a double layer of this material should be installed. Return to contents</a>

    Additional points and recommendations

    Repair of corner zones. When working with plasterboard sheets, the problem of chipped corners often arises. To do this, you need to do:

  • Thoroughly clean the damaged area from dust and dirt.
  • Using a primer to open the corner, thereby providing a strong grip of putty and foundation.
  • On the damaged area is installed perforated, a special detail, which later shpaklyuetsya.
  • Here it is necessary to strictly monitor the correctnesslines, otherwise the angle will be uneven. Restoration of a plaster base under painting. The technique for carrying out repair work is carried out according to a similar scheme discussed earlier. An important place here is occupied by the process of applying paint to the surface. The main problem will be the correct selection of the desired shade of enamel. If it is impossible to carry out such actions, the entire surface is painted again. Drywall repair is also carried out under wallpaper. To carry out such actions, the sheets should be well wetted so that they can be easily removed. As soon as the wallpaper is removed, the nature of the damage should be assessed. Significant damage to the material indicates its complete replacement. This method will be more convenient and inexpensive. Usually, as a result of removing wallpaper from the surface, the paper base of the drywall is torn. As a result, the surface is bumpy and rough. Such uneven areas can be eliminated by simply wetting the surface. After moistening the base, the top layer of drywall is scraped off with a knife. Only protruding and interfering elements should be removed. When removing protruding parts, do not scratch the surface too much, which may cause new surface defects to appear. You can also use sandpaper to clean the paper base.</ ul>
