Anonymous users2024-01-24The main reasons for the hollowing of tiles are: the mortar is not full or the tiles are not gently beaten and squeezed densely when the tiles are paved; The tiles are not soaked in water or soaked enough before they are laid; The plastering of the base layer of the wall is not treated as required or the garbage of the base layer is not cleaned up. The tiles should be soaked in water for more than 2 hours before paving, so that the tiles can fully absorb water, and then take out the shade to dry or wipe the clear water; Check whether the plastering of the wall base meets the requirements, and the stolen goods and dust of the wall base must be cleaned; When paving, the back of the tile is covered with cement mixed mortar or 107 cement slurry and the wooden handle of a small shovel is tapped on the tile, so that the cement grout is crowded with the back of the tile, and then pressed hard to make the tile firmly combined with the wall base.
Special attention should be paid to the fact that when the back of the tile is full of mortar, it should be plastered into a hypotenuse on the four periphery of the tile, and leave some gaps in the middle, so that when pressing and tapping the tile, it will not cause the mortar to overflow everywhere, and the mortar can be full, and the tile and the wall are firmly combined. After the mortar is solidified after the tile paving, you can use a small hammer to tap the surface of the tile to check whether the tile is hollow. Hope it helps.

No, you don't. The forces on the building structure are very complex, and any point of contact can absorb the dispersion pressure. What's more, it touches the entire bathroom floor and the wall that is the same height as the floor?! I hope my answer can help you.
