10 tiles paving guidelines to prevent empty drums, curling, cracking, shedding- I
Why is the drum, the corners and even the falling off after the tiles are laid? In addition to the quality factors of the tile itself, improper handling during paving is also an important reason. From the cement mortar to the paving method, from the basic processing to the problem of leaving the seam, the irregular operation of each link may leave hidden dangers. To avoid problems, follow these important guidelines.
Tiles (especially glazed tiles) should be soaked in water for more than 2 hours before spreading to allow the tiles to absorb water. If the water content of the tile is not saturated, the moisture in the mortar will be absorbed prematurely, causing the mortar to shrink and appear to be empty, which will also affect the bonding strength.
Before the tile is laid, remove the soaked tiles from the water and wipe off the moisture on the brick surface for paving.
Cleaning tiles back residual powder
The process of tile production and processing leaves powder or mortar on the back of the tile. This layer of powder may form a barrier layer to affect the bonding of the cement mortar and the tile, reducing the adhesion and causing the hollow drum. Even if the tiles are soaked in water, there is no guarantee that the mortar will be removed. Therefore, it is best to check before paving to ensure that the mortar has no residue.
Paving tiles with seams
After the tile is laid, there will be curled edges and curled corners, which may be due to improper seaming when laying tiles. Tiles and cement mortars will expand and contract with the change of physical environment. If the tiles are not left without seams or the gaps are too small, the adjacent tiles will squeeze each other, and the position of the first force will be easy to appear. Lifting phenomenon.
Press the tile in time after paving
After the tiles are laid, it is necessary to press them in time to make the cement mortar or tile adhesive more uniform and enhance the adhesion. Floor tiles can also be tapped with a rubber hammer to enhance their stability.
