Why does the bathroom leak? Of course it is because waterproofing is not done well. The waterproof material that is available on the market is very much, and the selectivity is very great. The effect is very good. The main thing is that you need to pay attention to many details in the construction, otherwise it is easy to go wrong. Let us talk about what we need to pay attention to!
First, leveling the bathroom floor first
If you want to replace the bathroom floor tile, after the original floor tile is cut, you must first use the cement mortar to level the floor, and then do waterproof treatment. This will prevent leakage of the waterproof coating due to uneven thickness.
Second, wall treatment is also very important
Approximately 30 cm high waterproof paint is applied on the wall of the general bathroom to prevent water from collecting through the wall. However, if the bathroom wall is a non-load-bearing light wall, the entire wall should be painted with waterproof paint. If you use a two-seater shower screen, the two walls that are associated with it must also be covered. If a bathtub is used, the height of the waterproof material on the wall next to the bathtub is also higher than the upper edge of the bathtub.
Third, the seams should be brushed into place
The seams between the bathroom wall and the seams between the upper and lower water pipes and the ground are the most prone to problems. In construction, we must urge the workers to deal with these corners. All waterproof paint must be applied in place.
Fourth, keep the water open
All sewers in the bathroom, including floor drains, sanitary ware plumbing, etc., should be kept open.
Fifth, waterproof experiment must be done
After the construction of the bathroom was completed, all the water in the bathroom was blocked, and a 25 cm high “can†was built at the entrance. Then, 20 cm of water was poured into the bathroom. After 24 hours, check the surrounding wall and floor for any leakage. This 24-hour waterproof test is the key to ensuring the quality of the bathroom waterproofing project and must be done.

Decoration construction knowledge
Description:Rockwool FELT is a kind of insulation materials with chosen high-quality natural rock as the main raw materials,such as basalt,dolomite,melted in the cupola,centrifugate into fiber in high speed by four rollers centrifuger and sparying a certain amount of binder,dust proof oil and moisture repel.
ROCKWOOL FELT have higher strength and better elasticity. The folded rock wool board with certain compression resistance has greater drawing strength, and it does not tend to peel off and has greatly improved durability.
The Advantage of Fireproof Rock Wool Insulation and Mineral Wool Insulation
1) Small coefficient of heat conductivity and good capability of heating preservation;
2) Excellent fireproof capability, Excellent sound absorption and sound insulation capability;
3) Green building materils and no harm for body;
4) The rock wool has higher and better elasticity;
5)The folded rock wool board with certain compression resistance has greater drawing strength, and it does not tend to peel off and has greatly improved durability.
6)The felt can be with wire or glassfiber for reinforced.
7)The size can be 1m or 1.2m width,length can be made according to client's request.
