Why do you want to knock on the wall with a small hammer when you start decorating the house?

When decorating a house, you need to knock on the wall with a small hammer to check whether the wall is empty. If empty drum is found, it will be knocked out during decoration, and the wall construction will be carried out again in this area.

The specific method is to find a metal object and use it to tap and paste the four corners and center of the tile.

If there are more than two empty sounds at the tapping position, then it can be said that the tiles are not pasted well. If there is a space in the middle, remove it and paste it.

Harm of wall hollowing:

1. The ceramic tile at the empty drum is not stressed, and it will be easily broken by external force in the future.

2. The hollowing may lead to the gradual expansion of the hollowing range of the tiles in the later period, and finally the tiles will tilt or fall off.

3. Empty drum will make it difficult to drill holes in the wall in the future, and it is easy to break tiles.

4, empty drum will lead to water accumulation in the bathroom floor and rot and stink (this is the reason why many people have bad smell in the bathroom).

5. The hollowing not only reflects the appearance, but also reflects the serious problems that may exist in the construction technology (such as no galling before bricklaying).
