It can harm the occupants’ health.

1. Base Treatment

Before waterproofing, treat the bathroom floor and walls. They must be flat, clean, oil-free, and without loose or hollow areas. Any cracks should be repaired first.

2. Pay attention to waterproofing details.

Key areas in the bathroom, like floor drains and pipe outlets, are crucial for waterproofing. At these locations, use sealant to seal detailed areas. This will prevent waterproofing failures.

The bathroom’s waterproofing layer covers the floor and part of the walls, up to 1.8 meters high. During construction, first apply an interface agent to the cleaned base. This will improve the adhesion of the waterproofing layer to the base. Then apply the waterproofing material evenly in layers. Each layer of waterproofing must dry fully before adding the next. Usually, you will need 2 to 3 layers.
