Because of its decorative and functional properties such as durability, water resistance and ease of cleaning, tiles are widely used: walls, floors, ceilings, fireplaces, murals and swimming pools, and can be used both indoors and out. The traditional method of pasting ceramic tiles is the thick layer construction method, that is, the ordinary mortar is first applied to the back of the tiles, and then the tiles are pressed to the base layer. The thickness of the mortar layer is about 10 to 30 mm. Although this method is very suitable for construction on uneven bases, its disadvantages are low tiling efficiency, high technical proficiency requirements for workers, increased risk of falling off due to poor flexibility of the mortar, and difficulty in checking the quality of the mortar at the construction site. Strict control. This method is only suitable for high water absorption tiles, and the tiles need to be soaked in water before attaching the tiles to achieve sufficient bond strength.
