Work begin with preparation of strips gipsokartonnogo sheet. The width of preparation should be equal to the sum of width of a slope and a part of sheet which will come on a wall. In the area of a corner choose a groove (it has been above told how it becomes) and bend a slope under the necessary corner.
Before to put preparation into place, do not forget to define a corner of a dawn of a slope.
On fig. 99 the scheme of facing of window slopes is shown. By the same principle finish and podokonnye niches, and door slopes.
a Fig. 99. Facing of window slopes :
1 - obmazka a plaster solution; 2 - mastic; 3 - sheet GKL; 4 - shtapik; 5 - podokonnaja a board
In public buildings, schools (if they are finished GKL) corners can be very soon damaged. They are builders always consider and impose on corners predohranitelno-decorative wooden squares, apportions. Them usually krepjat nails. I advise to try for this purpose sulfitno-plaster mastic.
The apportions Pasted on it keep very strongly without any nails, I hundreds times have checked up it in practice.
