In the process of building construction, the laying of tiles is an important job. However, the problem of tile hollowing is a headache for many construction teams. Recently, I heard the story of a project manager and builder who inspected the quality of tiles on site, and after discovering a hollow tile problem, they decided to fix it with grouting. This decision caught my attention because I have been researching the problem of tile hollowing, and I wondered, can grout really solve the problem of tile hollowingFirst of all, we need to understand what tile hollowing is. Tile hollowing refers to the lack of adhesion between the tile and the floor or wall, resulting in the formation of air pockets inside the tile, which will make a hollow sound when struck by hand. Tile hollowing not only affects the appearance, but also may cause the tile to fall off, causing safety hazards.
So, why do tiles hollow?There are many reasons, such as improper treatment of the base layer, unreasonable mortar ratio, incomplete cleaning of the back of the tile, etc. In this case, the constructor found that the wall tiles were hollowed out in a large area, but the floor tiles were not hollow, which may be due to the large thickness of the wall tiles and the high water absorption, and the adhesive force of the mortar was not enough to support the weight of the wall tiles, resulting in hollow wall tiles.
So, can grout really solve the problem of tile hollowing?The answer is yes. Grouting is a commonly used tile hollowing repair method, which eliminates tile hollowing by injecting a special colloid into the air bladder at the bottom of the tile to increase the adhesion of the tile to the ground or wall. However, grout does not completely solve the problem of tile hollowing. Because if the base layer is not properly treated, the mortar ratio is unreasonable and other problems are not solved, the tile may appear hollow again.
In addition, there are some limitations to grouting to repair tile hollows. First of all, grout can only repair tiles that have been hollowed, and for tiles that have not been hollowed, grout cannot prevent the occurrence of tile hollowing. Secondly, the tiles repaired by grout may have color differences, which affects the appearance. Finally, grout repair requires professional tools and techniques, and if not done properly, it can lead to tile cracking.
Therefore, for the problem of tile hollowing, we should pay attention to both prevention and repair. During the construction process, we should operate in strict accordance with the construction specifications to ensure that the base layer is properly handled, the mortar ratio is reasonable, and the back of the tile is clean and thorough. At the same time, we should also regularly inspect the tiles, and once the tiles are found to be hollow, they should be repaired immediately.
Overall, grout is an effective method of tile hollowing repair, but it does not completely solve the problem of tile hollowing. We need to solve the problem at the source in order to truly avoid the occurrence of tile hollowing.
