As for the time required for this process, it still depends on the paint you use. Anyway, just wait patiently. When you start painting, you should brush the facade first and then the plane. The painting direction of plane and facade is vertical. When the film is semi-solidified again, coarse sand particles can be dragged, which can be combined with cement mortar in future construction.

The protective layer must completely cover the waterproof layer, and it should be firmly combined with the base layer, and there should be no omissions, and it should not bubble, crack or fall off.

If no leakage is found, then the project is qualified and the floor tiles can be pasted.
