The bathroom is generally the main place for water at home, and it is also a place where water is high. Therefore, bathroom waterproofing is very important, so how can we do it better and more effectively waterproof?

1, using paint waterproof

Ordinary residential toilets are small and have pipelines and floor slabs. Therefore, the coatings are often waterproof and rarely waterproof.

2, two waterproof coatings for the bathroom

Today's materials used for waterproofing are generally paints, while asphalt-based waterproof coatings are basically unused. The following are two commonly used coatings for bathroom waterproofing.

(1) Synthetic polymer polyurethane waterproof coating (such as polyester cloth, fiberglass cloth, etc.)

(2) SBS waterproof coating of high polymer modified asphalt (requires addition of carcass reinforcement polyester cloth, fiberglass cloth, etc.).

But for the owner of the first renovation, may you feel that the opener is not already waterproof? Why do you still need to waterproof the bathroom?

First, the developer made waterproof, but very water

The national law stipulates that every bathroom should be waterproof before the house is delivered, so the opener does make waterproof for each room.

But why do you have to waterproof it in the decoration? Because the waterproofing by the openers is really water! It is not waterproof, it can only be regarded as perfunctory, and it is only for inspection. The water-clearing room that has just got the hand can be said to be one of the waste products, and it is completely waterproof. Everyone can think about how much the openers are willing to spend to save their own money to make the bathroom waterproof for every type of bathroom in every real estate. The big deal is to do whatever you want, and check it out!

Second, the significance of doing bathroom waterproofing

In addition to the reasons mentioned above, the renovation process will inevitably damage the waterproof layer of the bathroom or other rooms. In the decoration notice, the property will generally stipulate that the owner’s decoration damages the original waterproof layer, and the warranty obligation of the property is terminated. It is necessary to do a second waterproofing, and it is also one of the guarantees for future residential safety.

In addition, in order to protect the bathroom wall waterproof layer should have a height of 1.8 meters. Therefore, in the decoration stage, the waterproof layer should be done again, which is also responsible for the residents downstairs.

Third, the bathroom is easy to leak water

1. Cracks occur in rubber concrete;

2. After the waterproof layer is completed, the subsequent process destroys the waterproof layer (applied brick);

3, the use of poor waterproof materials (cheap no good goods);

4, did not do as required waterproof layer or waterproof layer thickness (> 1.2mm);

5, did not do node processing as required (node ​​processing is not good);

6, the decoration of the slotted buried pipe, damage to the original waterproof layer caused by water leakage;

7. When the waterproofing is done, the base surface does not meet the requirements, and there are phenomena such as sand and looseness;

8. The shrinkage of water pipes and cement produces cracks.

Fourth, what is the danger of not doing waterproofing?

Water is pervasive. For places that often come into contact with water in the bathroom and kitchen, as long as there is a leak in one place, water will form in the floor and leak into the downstairs, affecting the neighborhood, which may cause serious property claims and A legal dispute has occurred. Secondly, if you refill the waterproof, it will be about 3-5 times waterproof before the renovation. Therefore, the waterproofing of the bathroom must be done, and the quality must be controlled. Otherwise, it would be very troublesome if water leaks and repairs after check-in.
