Js waterproof material also has many advantages, such as good crack resistance and double extensibility. This is because of its good adhesion and good adhesion to most materials. However, js waterproof material also has its defects, that is, the shelf life is only 6 months. Must be placed in a sealed environment, not exposed to the sun and frozen, and the storage temperature should always be kept at 5~25 degrees Celsius.
Js polymer material is mainly made of polymer emulsion and ordinary portland cement. This new waterproof material can form a high-strength waterproof film when coated on the base. Bian Xiao said so much, let's take a look at the use of js waterproof coating.
1. When js waterproof coating is used, the wall surface should be cleaned without oil and dust, and some uneven or crisp places should be repaired and leveled with cement.
2, in the underlying construction, js waterproof coating should be diluted with 2 times of direct water, and rubbed back and forth for at least 3 times to prevent peeling and metope, and at the same time, it is necessary to make a good paste between the surface and the grassroots.
3, in the middle of use and surface coating construction should be directly painted, and in use without cement can't add water.
4. js waterproof material for wet environment and construction can be used directly as long as it is water. If the environment is too dry, it needs to be used with cement.
5. The dosage of primer is about 0.3~0.5 kg/m2, which can be changed appropriately according to the situation.
Having said that, I believe everyone must have a better understanding of js waterproof materials, and hope to help everyone in the use of js waterproof, so that everyone can have a higher understanding of the waterproof in decoration.
The development of this new material has greatly improved our living standards, and we hope that more new materials can appear and bring greater improvement to people's lives.
