Product Details

Weidun WD002 Polyurethane Waterproof Coating is a type of protective coating that is used to protect surfaces from water , moisture , and other elements .

It is a type of sealant that is applied to the surface of a material to create a waterproof layer . This layer is highly resistant to water and will not allow it to penetrate into the underlying material , preventing damage from water or moisture .

Polyurethane waterproof coatings are available in a variety of forms, including liquid, aerosol, and tape.

They can be applied to a variety of surfaces, including concrete, metal, wood, and plastic, and can provide a range of benefits, such as improved durability and longevity, as well as protection from water, moisture, and other elements.

Compared to solvent-based coatings, the low odor and zero VOC content of WEIDUN polyurethane coating make this range the ideal choice for on-site application.

Applications: any roof, bathroom, kitchen, external wall, etc.

How To Use

Substrate Preparation:

All surfaces must be sound, dry, free from grease, dirt, or other contaminants and must be reasonably smooth.

In case there is a need for filling, the ready-to-use, cementitious mortar screed may be used.

As for the kitchen and bathroom, the floor drain, and internal and external corners need to be sealed.

Application:

After substrate treatment, WEIDUN Polyurethane coating is applied by brush or roller in 2 layers. 8 to 24 hours after the first brush, depending on weather conditions, a second coat is applied.

Consumption: approx. 1.0-1.5 kg/m2, depending on the substrate.
