After the bathroom is waterproofed, do I need to do anything before the mortar leveling?

Spread the cement mortar directly on top of the waterproof layer.

After the waterproof layer is decorated, do a closed water test, so as to ensure the effect of the waterproof layer.

For the decoration of the bathroom, the most important thing is to do a good job of waterproofing. After all, there is often water in the bathroom, and if the waterproof layer is not done well, then it will affect the residents downstairs and bring trouble to themselves. Therefore, the ground base layer should be cleaned, and then the waterproof layer should be created with paint.

When creating a waterproof layer, you must pay attention to painting twice, so as to avoid missing places and make the waterproof layer perfect. In addition, after doing a good job of the waterproof layer, you must remember to do a closed water test, so as to ensure the effect of the waterproof layer.

It depends on the type of water repellent and the instructions for use.

Most of the new waterproofing agents can be mixed with cement mortar, or mixed with the powder provided by the product (e.g. JCDecaux) or directly mixed with the net cement by the waterproofing agent (e.g. Lloyal) and then applied to the floor.

Both have very good water resistance.

Since these high-quality waterproofing agents are easy to operate, you only need to understand the instructions to guide the workers to implement. If the worker has done it before, there is no problem.

I hope mine can help you.

Hello, after doing a good job of waterproofing, you can use cement mortar to fill in and then tile paving, if you don't want to pave the tile is no problem, don't, do not use pure cement paste on the waterproof layer, pure cement paste thermal expansion and contraction reaction is more obvious, may cause damage to the waterproof layer.

The cement mixed with construction glue and cement can be brushed before laying cement mortar, which can prevent layering.
