First you need to calculate how much material is required to work. To do this, measure the area of the room, which must be covered with ceramic tiles. It is recommended to purchase 15% more tiles than will be required based on the calculations of the area of the cladding. There are several ways of wall cladding using ceramic tiles: diagonally, seam to the seam, and screaming. Tiles are laid diagonally in cases where, for example, a balcony, porch, or some other room has the shape of a hexagon or trapezoid. If a ceramic tile is put on such a surface in the usual way - even rows of tiles will emphasize the irregularity of the surface. This also applies to rectangular structures.
