Why do we need to leave a joint in the laying of bricks?
1. Ceramic tile has the problem of thermal expansion and cold shrinkage
Ceramic tile and cement mortar pasted with ceramic tile will have the problem of thermal expansion and cold contraction. In the process of temperature or humidity change, ceramic tile and cement mortar will have certain expansion and contraction. If there is no seam left, it will lead to bulge or cracking of ceramic tile in the later use process.
2. There are reasonable errors in tiles
Although the ceramic tile is now mechanized production, but in the process of product production, there will be a certain size error (too large error belongs to the quality problem of the product). If there is no seam left, it is easy to have uneven joints when tile paving, which will affect the beauty of ceramic tile.
3. There are errors in the construction of workers
Tile paving belongs to a highly skilled construction project, workers in the whole paving process, it is impossible to completely pave each piece of brick without error, the worker's mood is bad, day and night, and other different conditions of tile paving, the effect will be different, if there is no seam, it is also difficult to ensure the tile joint straight problem, shadow The beauty of the tiles.
