Surface preparation

Prior to the application of damp-proof or waterproof insulation, the surface must be made level (with no cracks, defects, protruding elements) and free from any dirt which may reduce the product’s adhesiveness (grease, oils, lubricants, laitance). Make all edges smooth, round off all the corners using cement mortar and install plaster coving inside joints between vertical and horizontal surfaces. Fill in any defects, joints, honeycombing or gaps. Prior to priming, fill in any irregular surfaces that have voids or protrusions with cement plaster.
