Water-Based PU Polyurethane Roof Indoor and Outdoor Waterproof Coating

Product Description

China Multipal Color Exposed Metal Roof Water-Based PU Coating             
Water based polyurethane waterproof coating
 

DESCRIPTION
Product is made of self-cross linking pure acrylic emulsion, assisting with a certain amount of modifying agent, active agent, auxiliaries and pigment. It forms an elastic, hard and strong bonding strength film, which is completely strong and flexible waterproof system with the inter area, adaptive to deformation of structure, to achieve long-term function of waterproof and seepage resistance.

APPLICATION GUIDE

 

PRECAUTION

• Second layer is the thickest one, the third one is very thin, just for leveling.
• Interval time depends on the application site, but typically full drying time is about 20 hours.
• Fiber reinforcing layer is necessary for inside corner internal corner, floor drain, pipe joints etc, the lap width should not be less than 100mm, extensive application after joints treatment.
• Use PU out after opening, time within 8 hours. Long-term storage will cause the forming of a thin film on the surface. Remove this when application. Does not affect the performance of product.
