It can be cleaned repeatedly without special chemicals. Supplied in a single pack and available in matt or gloss finishes. Excellent adhesion to concrete, brick, stone, render, timber, metal, cladding, and most previously-sealed surfaces (use on masonry paint should be patch-tested first for adhesion).
