How to make the bathroom waterproof?

Before construction, it is necessary to ensure that the dry waterproof coating on the ground is fully coated, without omission, firmly combined with the base, without cracks, bubbles and falling off. The coating height should be consistent, and the thickness should meet the requirements specified in the product. It should be noted that the coating should wait for 1 pass, and the second pass should be dried before brushing. The specific time depends on the product characteristics.
