1. Remove the original floor tiles and wall tiles.
Remove the original wall tiles and floor tiles, this step is generally for the second decoration of the old house, if it is a new house, then this step can be skipped, generally using a gray knife, the scraper can also remove the original floor tiles.
2. Plug the sewer pipe.
The waterproofing of the bathroom is usually carried out after the completion of water and electricity, so the sewer pipe must be blocked before doing waterproofing, the purpose of this is to avoid blockage, the small water pipe is blocked with a nut, and the large sewer pipe (such as the toilet sewer pipe) is blocked with PVC winding film.
3. Ground and wall leveling.
The leveling here is usually the ground plastering treatment, the ratio of mortar cement and sand is between 1:2-1:3, pay attention to the thickness of the leveling should not exceed 3cm. The horizontal and vertical errors should also be controlled within 5mm.
4. Make a waterproof layer.
First of all, the wall will be slotted with cement to clean up the base layer, the details of the additional layer construction, in the pipe root, floor drain, yin and yang corners, and other weak parts that are easy to leak evenly painted, painted waterproof paint twice, painted longitudinally and horizontally, but also remember to do a good job of protective layer, after waterproof drying, release water to do 48 hours of closed water test.
