After the wall is waterproofed, what kind of tile will be more firm?

For the walls of the shower area to be waterproof, the walls must be filled with more than one meter, and the other areas are only 30 cm high. The ground must also be waterproof, and it must pass a closed water test after completion.

Why does waterproofing affect tile stickers?

The back of the tile is coated with cement mortar, and the moisture should penetrate into the wall and become hard, but the wall becomes smooth after the waterproof layer, and the water cannot penetrate, and the drying is slow, and it is difficult to fix the wall tiles.

Even waterproofing does not affect the construction method of tiling:

Method 1 (suitable for tiles with high water absorption) waterproofing is strictly sanded according to the ratio recommended by the product, and a little hair is made on the surface when sanding. When tiling, the cement mortar layer should not be too thick, and there should be a gap between the bricks to prevent thermal expansion and cold shrinkage bricks from squeezing each other. The proportion of cement is large, and the bricks are quickly solid, but the expansion coefficient of cement mortar is large, and it is easy to press bricks after paving.

Method 2) Suitable for tiles with low water absorption (using ceramic tiles for pasting).

Brick laying instead of cement mortar, viscosity is several times stronger than ordinary cement mortar. I advise the restroom not to choose bricks that are too large. Such heavy bricks are more difficult to pave.

If you want to use large bricks for paving anyway, it is recommended to use glass bricks and stone bricks and rubber water-based tile adhesives for paving. This way, you can rest assured that the road will be paved with large bricks.

Can you tile the toilet immediately after the waterproofing is completed?

The waterproofing workflow of the bathroom is to smooth all the ground with cement mortar once, and then waterproof after drying. Those owners who ask whether they can put tiles immediately after waterproofing, the first thing to make clear is that waterproofing is not just once. Generally, waterproofing will be carried out 2 to 3 times.

In addition, the order of waterproofing is also very particular. For example, after completing the wall waterproofing, the wall tiles are pasted, and then the floor tiles are pasted after the floor is waterproofed. Because the ground is often stepped on, it is easy to be trampled on if the ground is waterproofed first.

In general, there is a hardening period of 5 to 7 days after the waterproofing layer is completed 2 to 3 times. When the hardening period comes, it is necessary to retest whether the waterproofing is well done or whether there is no leakage. Therefore, it is necessary to further add water for 24 hours to confirm whether the floor water level of the house has dropped and whether there are signs of water leakage in the toilet next to the downstairs.

Because tiling must be done after this, it is a big mistake to apply tiles immediately after the waterproofing is over.

If there is no water leakage, remember to use cement mortar for waterproof protection. The purpose is to prevent the surface of the waterproof layer from being damaged twice in the tiling operation. If it still leaks, it is necessary to re-waterproof it because the waterproofing is not thorough.

Wait for drying and testing according to the last process, and if there is no problem, you can lay wall and floor tiles.

After waterproofing, it is recommended to stick small tiles, because small tiles are more adhesive than large tiles.

Sticking general tiles will be firm, because you have laid a good foundation, and the work behind will be easy, don't worry.

Sticking small tiles will be a little stronger, because small tiles are not so heavy and are stronger.

Applying waterproof paint to the exterior wall has no negative effect on the firmness of the tiles being pasted.

The reason for the phenomenon that the existing waterproof coating is not good for pasting tiles: the cement mortar has high water absorption, and the waterproof coating blocks the passage of water to the wall, so that the cement mortar has not been completely bonded with the ceramic tile firmly, which has been dry and solid, resulting in the tile bonding is not firm.

When doing waterproofing, it is necessary to ensure 3 points, first, to keep it free of dust, second, it must be dry, and third, after doing it, it can not be drenched, can not be touched or stepped on... In this way, waterproofing is considered to be good. In fact, in the waterproof wall tiles, it is best to use glue, there is a kind of glue, but in fact, many with cement, there is no big problem.
