One-component polyurethane waterproof coating

Recommended For

Roof waterproofing projects, underground waterproofing projects, waterproofing of pipe galleries, kitchens, bathrooms, pools, etc.

Packing 

One-component polyurethane waterproof coating is available in 20kg/pail.

Reference dosage

Under normal conditions, when the thickness of the waterproof layer coating is 1.0mm, the recommended dosage is about 1.6kg/㎡-1.8kg/㎡ (the actual dosage depends on the base condition and coating thickness).

Advantages

1.It chemically reacts with moisture in the air to form a flexible rubber waterproof coating, which is dense, without pinholes or bubbles.

2.High strength, large elongation, good rubber elasticity and resilience, and strong resistance to deformation of the base layer.

3.Resistant to water erosion, chemical erosion, and mold.

4.single component, ready to use and convenient to use

5.Safe and environmentally friendly, free of toxic solvents such as benzene, toluene, and xylene, and free of coal tar components.

Application Procedures

1. The base layer should be solid, flat, clean and dry (moisture content not more than 8%), with no dust, debris or oil stains on the surface, and theyang corners should be treated to have no sharp angles.

2. Polyurethane can be applied by scraping or spraying. When applying by scraping, the amount of each coat should be controlled at about 0.7kg. The thickness of the scraping should be uniform. The interval between each coat should be determined according to the temperature and humidity. The first coat should be cured and not sticky. When spraying, the amount of each coat should be controlled at about 1kg according to the spraying equipment. Multiple coats should be applied to reach the designed thickness.

Attentions

1.The coating must be tightly used up within two hours.

2.Do not construct in sleet and sand blown by the wind. Avoid constructing in high temperature at noon or under 5℃

Limitation

• Not subject to any traffic and must be protected by protective screed or polystyrene board.
• Do not apply with high consumption than recommended amount.

Safety Precautions

We recommend the use of protective gloves during application.if there is contact with eyes and skin,wash immediately with plenty of water.Seek medical assistance immediately.
