When laying any type of tiles, whether ceramics, or porcelain tiles, always have to cut the tile to fit the required size. Cut the tiles on the front side, cut the surface glaze, affecting the part of the base of the tile (crook). By the way, do not forget to buy in advance a foaming agent for foam concrete, now it is popular.
In order to break the tiles with the help of a ruler, marked the cut line, then with a glass cutter, with a strong pressure, draw in the ruler twice. The formed in-depth line can easily break, it is worth only (on the bottom of the tiles) to hit any wooden board, which will soften the rim of the tiles according to the necessary cut evenly. Or, putting the tiles to the surface of the table and press on it, it will also be broken carefully.
In the case of the necessary fairly narrow tile strips (20-30 mm), in this case the cut line is also planned, and we break the tiles with ticks. For splitting tiles, you can also use a pointed steel hammer. This method is most often used for cracking tiles precisely for floor flooring. To do this, the tiles are laid on the knee and the cut of the hammer is made by notches along the in -depth line of the cut.
