Blockade is quick drying, saving time on jobs that require multiple coats or to be quickly overcoated with emulsion. It covers glossy and hard-to-paint surfaces such as tile, varnish or gloss paints with no sanding needed. The pure shellac base permanently blocks stains and odours, covering even the darkest of colours.

• Blocks odours including cigarette smoke, other smoke smells and damp
