DESCRIPTION

Ardex P4 Ready Mixed Rapid Drying Primer 8Kg

ARDEX P 4 is a ready mixed, rapid drying multi-purpose primer designed to improve adhesion before the application of ARDEX tile adhesives and floor levelling compounds. Suitable for internal and external walls, floors and ceilings, it creates a textured grip surface that promotes excellent bonding on both absorbent and non-absorbent substrates. Its drip free, solvent free formulation makes it easy to apply, while the white colour clearly highlights primed areas for complete coverage. ARDEX P 4 dries in as little as 30 minutes and is ideal for use in kitchens, bathrooms, porches and other areas subject to moisture.
