Do not forget that after the tile is pasted, it will be necessary to use a ceiling skirting board, which will serve not only a complement to ceiling beauty, but also make it inconspicuous gluing tiles. It is worth noting that if you decide to glue the tiles in a small room, then do not resort to the help of markings. It will be enough to start glue from the corners of the room. Along with traditional gluing tiles, you can also resort to dialing diagonally. Its advantage is that this will not notice obvious differences in the walls. Also pay attention to gluing tiles in a checkerboard pattern. This will allow you to diversify the chosen room a little and also hide some inaccuracies in the room layout.
