The main reasons why the construction master stepped on the tiles after putting them on were as follows: 1. Increase the bond effect: Air and moisture may enter the tile during the laying of the tiles, affecting the bond between the tiles and the mortar. When the master walked on the newly pasted tiles, he could use his weight to squeeze out excess air and moisture to make the tiles and mortar come into closer contact, reducing the risk of hollowing the tiles. 2. Checking the smoothness: Stepping on the tiles allows the master to intuitively feel the difference in height between the tiles, and adjust the unleveled areas in time to ensure the final laying effect. This method is faster than tool detection, and the advantage is more obvious when working on a large area. 3. Increase construction efficiency: After the tiles are laid, they need to be completely dried and solidified before the next step can be carried out. This process takes a long time and will affect the progress of the project. Treading properly can compact the tiles, so that the mortar is evenly distributed, improving the curing efficiency and shortening the construction period. However, it was not recommended to step on the newly pasted tiles. It was best to wait until they were completely cured before stepping on them, otherwise it would affect the tile bond. The construction master would judge whether he could walk on the tiles without affecting the stability according to the state of the glue, the size and weight of the tiles, and the master would basically take protective measures such as wearing soft-soled shoes and walking slowly. Non-professionals were best not to imitate. The novel " Humph, Call Me Senior Brother " is equally exciting. Everyone is welcome to click and read it!
