Application method

All ground floors should incorporate a damp proof membrane. Dusty or porous surfaces should be primed with Norcros Prime Bond diluted 1:4 with water. For impervious backgrounds a slurry bonding coat made of one part Norcros Prime Bond to two parts Norcros Pro 50 should be applied to the substrate using a soft brush. Once dry the slurry will provide a key coat onto which the levelling compound will form a strong bond.
