Dulux Pre-Paint Dampshield 20L

Dulux Pre-Paint Dampshield 20L. A water-based damp barrier for interior and exterior cement plaster and concrete vertical wall surfaces containing up to 50% moisture. It reacts with the moisture in the wall to form a barrier against rising and penetrating damp, and protects the paint on top against peeling, efflorescence and mould caused by damp. How to use: stir until even, thin the first coat 10% by volume with water and apply 2 coats by brush or roller to a minimum total dry film of 100µm. Allow 4 hours between coats or before Dulux water-based paints, and 16 hours before solvent-based enamel (maximum 7 days at 23°C). Clean tools in warm water. Specifications: Colour: White; Finish: Matt; Pack: 20L; Coverage: approx. 5m² per litre per coat; Touch dry: 1 hour; Binder: modified acrylic, water-based.
