Generally speaking, grade 1 waterproof (20 years service life), waterproof coating film is no less than 2.0mm, grade 2 waterproof (10 years service life), waterproof coating film is no less than 1.5mm. But it is not said that the thicker the better waterproof coating thickness, on the one hand economy is not good, on the other hand the thickness is too big easy to lead to cracking.

To assure the laid quality of waterproof layer and save waterproof coating, the position besmear such as basic level, inside and outside wall brusher waterproof coating place to answer level off, without concave and convex, honeycomb pockmarked surface, float ballast, float ash, smeary etc.

Prepare waterproof coating, circular waterproof coating mixing bucket, measuring tool, roller, brush, scraper, stirrer, etc. Mix the waterproof coating according to the instructions of the product and mix it evenly with the agitator.

In the pipe root, pipe, Yin and Yang Angle, construction joints and other prone to leakage should be enhanced treatment. Gouge in the pipe root, pipe around the use of instantaneous plugging agent to seal, and then brush with a brush brush one to two times waterproof paint; The Yin and Yang corners and construction joints are reinforced with polyester cloth, and then the waterproof coating is scraped with a scraper. The width of polyester cloth is 300mm.

After the detail node is processed and the coating is dried, the first large surface coating is carried out. Construction can use roller coating, brush coating, scraping coating and other methods, the construction should be uniform, can not have local deposition, and coating to brush for many times to leave no bubbles between the coating and the base. After the first coating drying (generally 6-8 hours interval is appropriate, the specific detection method is to touch the non-stick finger marks), the second coating of the construction, the direction and the first mutually perpendicular, construction should be uniform, no local deposition. After the second coating drying, the third coating of the construction. The third coating adopts the long-handled roller for rolling coating, the direction of rolling coating is perpendicular to the second coating, and the rolling coating should be uniform, without local deposition to improve the smooth and smooth effect of the coating surface. When the coating is closed, the waterproof coating should be used for multiple times to ensure its intact waterproof effect.

Construction should be brush side inspection, found defects in time to repair, site construction personnel, quality inspectors must follow the inspection, inspection qualified before entering the next coating construction, especially pay attention to the plane elevation junction, corner, Yin and Yang corner is correct.
