Try not to damage the original waterproof layer
When the new building is delivered for use, the bathroom is generally waterproofed, but most of the people's decoration will be paved with floor tiles, leveling the floor, and re-arranging the water and sewage pipelines. This will destroy the original waterproof layer of the bathroom, so the waterproof layer of the bathroom is re-established. Be sure to redo the waterproof when decorating. First use the cement mortar to level the ground, then do waterproof treatment, first clean the floor, and then repeatedly paint with polyurethane (water glass) waterproof coating 2 to 3 times. The joint between the wall and the ground and the ground joint between the water and the water are the most likely to leak. It is necessary to urge the workers to handle these corners and the waterproof coating must be applied. Require the decoration team to do the cement roots for the upper and lower pipes of the kitchen and bathroom. Brush the 10 to 20 cm polyurethane waterproof coating from the ground, and then re-do the polyurethane waterproof to enhance the waterproof.
"Leak test" test waterproof
After the waterproofing project is completed, seal the door and the water outlet, fill the bathroom floor with water to reach a certain liquid level, and make a mark. If there is no obvious drop in the liquid level within 24 hours, the roof of the house downstairs does not occur. Leakage, waterproofing is qualified. If the acceptance is unqualified, the waterproof project must be redone and re-inspected. Don't neglect this link. A lot of road repair teams don't do waterproof at all. They all finish the glass glue, so once the water leaks afterwards, it is too late to remedy. Therefore, the waterproof test must be done. After confirming that there is no leakage point, lay the floor tiles again.
The bathroom often has water, and it is easy to slip on it. Therefore, it is best to use anti-slip floor tiles with raised patterns. This floor tile not only has good waterproof performance, but also is not too slippery even in the case of water. . At the same time, the ground should be slightly inclined to the ground drain to facilitate flushing.
