Stick tiles on the wall to reduce hollowing and prevent tiles from falling off.

When decorating and tiling at home, we always see the decorators pulling and knocking on the wall with shovels or other tools until rough grooves appear on the wall. Later, when I asked, I learned that the masters were doing the wall roughening treatment, so that the contact between the tiles and the wall could be stronger.

First, should all the walls be painted?

In the past, there seemed to be no special requirements for tiling, because the cement wall to be tiled at that time was not very flat, so cement mortar could be used to tile directly, and some would use tile glue directly. If it is a rough house, the wall itself is rough, which can save the process of tiling. However, if it is a kitchen and bathroom, because it is waterproof and scratched after waterproof, it is necessary to roughen the wall surface, otherwise the tiles will fall off because they are not firmly pasted.

Tiling and napping

What needs special attention is that after the developer delivers the house, many people have to redo waterproofing after taking over the new house. If the walls have been painted, all the painted layers must be cleaned up. If you don't clean it up, you can't brush it, so you have to shovel off a sum of money where you have brushed it, and it takes another sum of money to redo the waterproofing, and then repair it after waterproofing. So everyone should pay attention. If the developer is waterproof, I think it is necessary to shovel a circle under the wall. It used to be waterproof, but now it is 10~ 15/ m2.

Second, how to take a nap on the wall?

1, if the wall is already very hard, you can draw many grooves on the wall with a cutting machine. This is a reliable and practical method. After sanding, you can directly stick tiles, which are generally very strong.

2. Some decorators will shake it with a broom. Although it is more labor-saving, they will stick tiles before the plain cement slurry is dry, which is easy to empty and fall off. At least there should be a wheel to roll it. At the same time, after sanding with tile glue and cement slurry, you must wait until the wall is dry and hard before sticking tiles.

Let's analyze several failure cases of hair pulling.

Tiling and napping

1, casually dumped twice with a broom, and all the sticky and soft walls were pulled down, and the bricks were pasted just after the hair was pulled.

2. Because the wall is hard, just pull it a few times, and pulling the hair fails.

3, the whole block, although there are grooves, is too smooth, and the contact with fair-faced concrete is not strong enough.

As a result of these mistakes, it didn't take long for the tiles to fall off.

Tips: If you want to reduce the empty drum phenomenon and prevent the tiles from falling off in the future, you must do a good job of napping. For more details of decoration information, please continue to pay attention.
