Tiles falling off has always been the most troublesome. Not only do we need to remedy the problem, but we also need to find the reason. Why do the tiles fall off? Finally, we have to find a solution. I believe most people don’t know much about this, so let’s Let’s take a look at today’s topic!
Because most people don’t know what causes ceramic tiles to fall off, so let’s first learn about the reasons why ceramic tiles fall off, and then learn about the methods to prevent ceramic tiles from falling off!
1. Reasons why ceramic tiles fall off
1. The wall base was not watered
The wall base is not fully moistened before laying, causing the water in the cement mortar and bricks to be sucked away. The mortar does not have enough humidity during the setting time to fully bond the ceramic tiles. Wet the base layer with water the day before paving, and control the humidity at 30-70%.
2. There are not enough seams in the ceramic tiles
Ceramic tiles are ceramic products fired from natural soil. They expand and contract with changes in temperature. There are no seams in the ceramic tiles. The ceramic tiles will squeeze each other and fall off. Generally, a seam of 1-2mm should be left, just like the concrete pavement must be cut to leave seams.
3. Second tap
Many people find that the tiles are uneven after laying them, and they will hit them twice to flatten them, which will cause the mortar that has lost part of its moisture to loosen.
4. Improper selection of cement labels
The grade of cement mortar indirectly affects the coagulation effect between it and the ceramic tiles. If the cement grade is not enough, the viscosity is not good, and if the cement grade is too high, once it hydrates and releases heat quickly, the water will evaporate quickly. In addition, if the ambient temperature difference is too large, cracks will easily occur. Poor adhesion will easily cause the tiles to loosen or even fall off.
2. How to prevent tiles from falling
1. Tile soaked in water
Floor tiles, wall tiles, etc. need to be soaked in water. The purpose of this is to avoid weak bonding between cement, floor tiles, and walls, causing hollowing and falling off, which will bring us some unnecessary troubles and problems.
2. Clean the base surface before laying tiles
If there is dirt on the wall or floor, it must be cleaned up to make the bond between the cement mortar and the base layer stronger;
Secondly, if there are cracks in the wall, remember to deal with them before laying the tiles;
Also, the flatness and verticality of the floor and wall must not differ too much.
3. When laying floor tiles, you must first level the ground
The order of laying is generally from the inside to the outside; if the road surface has a slope orIf you have an anti-odor floor drain, you should pay attention to find the slope according to the direction of the drainage pipe; wall tiles should be laid from bottom to top. For the sake of beauty, the bottom bricks should be laid backward.
When encountering the phenomenon of tiles falling off, the first thing we have to judge is why the tiles fell off and then find the cause and solve it. The above is the content shared today, I hope it can be helpful to you. Help!
