?1, grass-roots level treatment. Grass-roots surface should be solid, flat, clean, and no sharp corners, no cracks, no open water and oil and other defects.

?2, product mixing. Slurry preparation should be in strict accordance with the requirements of the ratio.

? 3, detail treatment. Before construction needs to be pre-pipe roots, yin and yang corners and other parts of the treatment into a rounded or obtuse angle, covered with mesh cloth, and painted multi-channel waterproofing coatings.

?4, large area painting. First grass-roots wetting saturated but no bright water, brush waterproofing coatings on the treated substrate, generally painted two to three times, each time the coating film is dry for the next process. The next painting direction should be perpendicular to the direction of the previous one, in order to achieve a comprehensive coating. Waterproof, moistureproof need 2~3 layers, can be brushed, roller coating. Construction conditions 5 ℃ ~ 35 ℃, avoid construction in the rain, high temperature, frost conditions.

5, closed water test. After the coating film is completely dry for about 24 hours, conduct a water closure test. The practice is: blocking the water outlet for water storage, water storage depth should not be less than 20mm, water storage time of 24 hours, the water has no significant drop for qualified.

The kitchen is a "fire and water" place, the environment is relatively complex, on the drain, under the drainage pipe, there are stoves and sinks in the middle, so the kitchen waterproofing is not optional, but it is waterproofing ability to require more attention must be paid.
