Sbs waterproofing membrane construction points and precautions

1. Base surface treatment: Drying is required (moisture content <8%), clean, solid, smooth, dust-free, and free of oil. The yin and yang angles should be rounded, and the joints should be pre-processed.
2. Primer coating: In order to facilitate the construction and ensure the quality of the coating, use the “Qinglong Brand” CQ110 crack resistance special base treatment agent to evenly coat the base layer and wait until it is dry (about 6-8h) before proceeding. Paint construction
3, paint construction: the use of a rubber scraper or brown brush evenly smear the paint on the base surface, the product is usually coated in three passes, each time the coating is about 0.5mm thick; coating must wait After one coat is dry (about 6-8h), the next coat can be applied;
4. To make the isolation layer: After the coating is dried (about 3 days), lay a layer of non-woven fabric or glass fiber cloth on the surface as the isolation layer (30-50g/m);
5.Reference amount: Coating: 2.3-2.5kg/m (thickness: 1.5mm) Base treatment agent: 0.2kg/m
Precautions
1. There is precipitation in the coating, which is a normal condition, and should be used with stirring;
2, the construction temperature should be above 5 °C, construction must ensure smooth air circulation in the construction environment;
3. During the coating process, if bubbles are found, they should be pierced with a needle roller within half an hour. The coating has a unique self-healing ability and does not affect the quality of the coating film.
4. During the construction process, the coating should avoid contact with organic solvents such as xylene and gasoline.
