1. We need to identify the quality of the tiles when selecting the tiles. The method is: firstly, whether the color of the tiles is uniform, no variegated color and small holes and black spots; secondly, whether the size is standard or not, the tile is measured with a tape measure. The length and width of the meter should be the same as the size of the factory, and the diagonal of the tile, if the diagonal size is the same, the tile is positive; then the tile is flat, the simplest and most effective method It is to overlap the two tiles of the same brand. If there are obvious gaps between the two tiles after the overlap or can be rotated, the tiles are not flat. Finally, it is necessary to see if the tiles have any color difference. The method is to take out several samples of the same type of tiles. Compare in bright places, if you can't see the difference in color, you can order it.
2, the tile after the paste can not have a whole piece of brick hollow drum (local empty drum can not exceed 20% of the whole brick), if there is a whole piece of brick hollow drums need to be reworked, under normal circumstances, each paste 100 bricks, Wall tiles allow one brick to be empty. Floor tiles allow two bricks to be empty, but they must be reworked. The owner of the reworked material (which is counted in the loss) is the responsibility of the owner. If it exceeds this range, the main The material is the responsibility of the construction party.
3. Under normal circumstances, the level of the floor tiles is allowed to have an error of 2 mm, the gap of the floor tiles must be the same, the diagonals of the bricks and bricks should be flat (allowing 0.5 mm error), and the bricks and bricks of the kitchen and bathroom walls are bricks and bricks. The corner should be leveled, and the level (allowing 1 mm error) and the verticality (allowing 2 mm error) should be achieved. If the bathroom and balcony floor tiles need to consider floor drain, the slope should be placed first. If there is no special reason, there must be no Water.
4. After the wall tiles and floor tiles are laid, the caulking agent or white cement is used to fill the wet mortar.
