Literally, walls should be rigid and waterproof. The ground needs flexible waterproofing.

Flexible waterproof, good elasticity, crack resistance, certain flexibility and smooth surface. This kind of floor is more suitable for use.

Rigid waterproof permeability, good adhesion, can better adhere to the ceramic tile, reduce the later empty drum fall off. Suitable for walls.

It is suggested that the toilet height 1 m 8 be brushed with rigid waterproof. There is also a napping process. If there is a wardrobe on the back, it is recommended to make the wall waterproof. Brush flexible waterproof below 30cm on the ground. Don't brush all of them with flexible waterproof or rigid waterproof in order to save money and trouble. This will go wrong sooner or later.

Pay attention to 99 and step less on the pit.

Waterproofing is a very important construction project. The quality of waterproof material directly affects the construction quality of waterproof layer, and house leakage will not only affect the normal life of family members, but also affect the life of neighbors. Therefore, owners must be careful when purchasing waterproof materials and choose good materials.

But there are so many waterproof materials on the market that many people are confused and don't know how to choose. As a result, they bought inappropriate paint, which not only did not solve the water leakage problem, but aggravated the water leakage problem in the room and made everyone miserable. So, how do we choose waterproof materials?

1, flexible waterproof materials and rigid waterproof materials:

Many people don't know the difference between rigidity and flexibility when they buy it, so it is difficult to buy a suitable waterproof coating, which affects the waterproof effect.

Flexible waterproof coating forms a thin film through chemical reaction, which isolates the building structure from the environmental water, thus achieving the purpose of waterproofing. Rigid waterproof coating can improve the impermeability of concrete base by improving its compactness and reducing its porosity.

2. Choose according to different environments:

Different spaces have different requirements for the performance of waterproof coatings. Therefore, in the selection, in addition to distinguishing between flexible waterproof coatings and rigid waterproof coatings, we should also choose according to different parts. Toilets and bathrooms are waterproof, which is very suitable for the waterproof combination of "hard wall and soft ground". Only when used in the right place can materials and materials play a greater role and achieve good waterproof effect. Flexible waterproof materials should be used in some special parts, such as pipeline roots and fan holes, to prevent the waterproof coating from cracking with the deformation of the base.

3, kitchen and bathroom waterproof has three characteristics. First, it is not affected by the external climate, the temperature difference changes little, and the elongation of the material is not high; Second, the area is small, there are many yin and yang angles, and there are many pipes passing through the building; Thirdly, the adhesive has good affinity. According to the above three characteristics, it is suggested to choose "two-component polymer modified cement-based waterproof mortar" and "mortar waterproof agent".

4. When choosing waterproof material products, you should also know the waterproof situation, such as manufacturer, address, production date, environmental protection certification, whether it meets national standards, packaging integrity, construction requirements, etc. In addition, it is recommended to provide sample comparison.
