During the construction of the waterproof coating, some waterproof masters have some bad habits, which greatly reduces the waterproof effect of the waterproof coating.
Therefore, in order to improve the quality of waterproofing projects, let us understand the precautions of waterproof coatings in the construction process.
1.
The base layer should be fully moistened and then painted with waterproof coating
The base layer has strong water absorption and is not fully wetted.
If it is too dry, it will not be smooth when applying the waterproof coating.

2.
The base layer needs to be painted with waterproof coating without clear water
Applying waterproof paint on the base surface of Ariake Water will overly dilute the liquid material, which will affect the viscosity and coverage of the paint, and even cause the paint to fail to form a continuous film.
3.
Single application should not be too thick
If the waterproof coating is applied too thickly at one time, it will cause slow drying, and it is easy to cause the surface to dry and the inside to dry, which leads to the problem of cracking and blistering of the thick film of the waterproof coating.

4.
Construction to avoid missing coating
The waterproof coating is not evenly applied, and does not completely cover the entire surface of the base layer, and cannot form a complete waterproof layer, causing moisture to easily invade the unpainted parts and affect the waterproof effect
5.
Take protective measures for the waterproof layer
After the waterproof coating is painted, protective measures should be taken to avoid contamination and damage in the later cross-construction, which will cause the waterproof layer to fail and affect the waterproof effect.

6.
The water-proof coating is completely dry and closed water test
The drying time of the waterproof coating will be affected by the construction environment.
If the waterproof coating is not completely dried, the water is drained for a closed water test, which will damage the waterproof layer and affect the waterproof effect.
