Waterproof coating ranges

★ Product Description download

According to heat-resistance and low temperature flexibility, it has 702 and 801 two types.

Product Specifications:

————

The material is made by elastic polymer modified asphalt mixed with a variety of resin softener and other substances; it is a kind of not curing product. It has excellent waterproofing and sealing effect in a wider temperature range. Its excellent elasticity, extensibility, and adhesiveness can make it keep flexible for a long time. It is an ideal sealing and waterproofing material.

④

Simple and convenient in construction

⑤

1. Construction is not allowed under rainy, snowy weather or severe environment.
2. Fillings should be dense, continuous, full, firm bonding, no bubbles, etc.

Notices

●Construction tools: scraper, grafter.
●Basic requirements: the base of construction joints must be hard, no loose sand layer; the seam must be kept clean, not dust, cement slag, rust, etc.
● caulking construction:
◎ First evenly coat the construction primer inside the seam, then use the squeeze gun to fill the caulks into the seam.
◎ Then use a scraper or grafter pressure the caulks in the seam firmly, screed and pressing to ensure that the caulks is closely adhere to the seam.
◎ Slant stubble should be applied to the joint. No gap should be left between the caulking paste and the seam wall to prevent air from being wrapped in.
◎ Press tight the screed caulks to make them flush with the edge of seam or slightly lower; then brush the primer on the surface with wool brush, the brushing thickness should exceed the caulking edge 4mm above, in order to assure the sealing.
