If incorrect or inadequate surface preparation, plasterboard can absorb too much moisture, especially if it is an ordinary, nevlagostoykom GCR, bend, warp, or, on the contrary, does not acquire the necessary adhesive properties and then simply glued wallpaper.

In the preparatory stage of the work, it is necessary to include priming and plastering of the surfaces of plasterboard sheets In the preparatory stage of work necessarily includes primer and luting surfaces of gypsum boards

Also, experts recommend paying attention to the correction of joints and joints between gipsokartonnymi sheets Also specialists recommend paying attention to the correction of joints and joints between drywall sheets

Some tools and materials will be needed for work with serpent:

  • Painter's knife;
  • Spatula;
  • Dry putty;
  • Water;
  • Solution dilution tank;
  • Construction mixer;
  • Sandpaper.

After the serpian is pasted, knead the putty and put a thin layer over the tape with a spatula. We wait when it dries, and then we clean it with sandpaper.

If the serpyanka does not stick to the seam, it can be "planted" on the PVA glue.

After grouting the joints, the surface needs to be opened with a primer again, and it is possible to decide whether to glue the wallpaper without first putting on the walls or still undergo a full cycle of preparation of the drywall for finishing works. The second option is preferable, especially if you are going to cover the walls with light thin wallpaper, which require a perfectly flat surface of light shade.

For correct processing of walls from gypsum board it is necessary to putty two fractions: larger( "Start") and small( "Finish").In addition, they need a small spatula and a large spatula, a construction mixer, a container for mixing the solution, sandpaper with different grain sizes.

The process of puttying the walls before wallpapering:

  • We prepare in the water the starting mixture to a thick consistency without lumps with the help of a construction mixer;
  • We collect on a small spatula a portion of putty and distribute it along the blade of a large;
  • With circular motion with a wide radius, put a putty layer on the wall with a spatula;
  • Remove the remains from the spatula with a small tool, and recruit a fresh portion;
  • When the "Start" layer is completely dry, it needs to be wiped with sandpaper with a large "grain";
  • After this, we carry out similarly the coating of the finishing layer;
  • We rub the dried shpaklevku fine nazhdachkoy.

After the puttying of the walls, two more primer layers must be applied. Do this not immediately, only after the final drying. The very primer dries quickly, it can be applied again after 45-50 minutes.

The thickness of the putty should not be more than a couple of millimeters. For uneven surfaces of such starting layers it is possible to apply a few, but for gypsum cardboard there will be enough one.
