To start the work, it is necessary to disguise all the flaws on the ceiling, that is, cover the seams, smash those places that do not reliably fit, leve the ceiling. Glue ceiling tiles in two ways: diagonally and in a straight line. In the first case, the work is carried out if the ceiling has many flaws and the surface is not even, the diagonal method will hide such a defect. It will be much more reliable to choose glue for gluing — putty. For pasting diagonally, you should at the beginning, make the ceiling marking, find the middle, the work begins from the middle of the ceiling. We draw two perpendicular lines in the center of the ceiling with a pencil, apply the first tile with a thin layer of glue on the first tile — putty in the middle and around the edges, and glue it to the middle of the ceiling, tightly press, lay the next row next to each other as close as possible to each other. Next, we lay the tile according to the marking along and down, then we lay the entire ceiling with tiles, while at the edges they will turn out not solid, and if it is economically cut, then enough for two floors.
