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.
