APPLICATION
Prior to application, confirm substrate moisture content, r.h. and dew point.
Seal coat:
Sealer coats can be applied by squeegee and then back-rolled (crosswise) with a
short-piled roller.
CLEANING OF EQUIPMENT
Clean all tools and equipment immediately after use with Colma-Cleaner. Once hardened, the material can only be removed mechanically. Wash soiled hands and skin thoroughly with hot soapy water.
