After about 3 years of renovation, these places cracked, and I don’t know why. As the cracks in the tiles expand, the consequences of falling off may occur, leaving safety hazards. Why do neatly laid tiles suddenly appear? How to prevent and deal with the tiles if they crack?
cracking
The expansion coefficient of the tiles is much smaller than that of reinforced concrete. When thermal expansion and contraction occur, if there is no gap or The gaps are insufficient, the foundation layer expands and contracts greatly, and the ceramic tiles expand too slowly, resulting in cracking. This situation causes cracking, the crack texture is smaller and short, and the edges and corners may also crack. First, clean the surface of the wall, and put it in marble glue . After it is dry, then use horn guard strips to stick it on, so that it can avoid damage to the tiles during the environment and use. , can also play a certain decorative role.
Repair
If the tiles are not "drink full water" before laying, the embryo body will not absorb enough water. After laying, the tiles will absorb the moisture in cement mortar , causing the tiles to crack, and in severe cases, it will also cause the tiles to fall off. Cracking of tiles caused by insufficient soaking water usually occurs shortly after the laying is completed. This requires removing the tiles and replacing them. However, this method is a big project. I am not a special recommendation. It is a waste of time and effort. The most important thing is to waste money.
Cracking
Another method is to grind the sides of the two tiles at 45 degrees and then seam them. This method is the most beautiful, but if the decoration master is not good at home, the effect will be much worse. You can also try to repair it with grout or porcelain white glue, but the effect may not be that good-looking. In fact, the construction of ceramic tiles at the corners of the sun is not difficult, but there are often problems such as these and other problems that affect the beauty or the tiles may collapse and crack.
