Water Seal

Johnstone's Trade Stormshield Water Seal is a water-based seal designed for use over masonry top coats to provide transparent waterproofing without changing the surface appearance. It allows above-ground surfaces to breathe, from concrete, cement rendering and blockwork to brick, stone and pebble dash, but it does not remedy structural defects with such surfaces. Offering coverage of 3-5 square metres per litre, depending on the nature and porosity of the surface getting coated, it is typically touch dry in 4-6 hours and can be recoated after eight hours.
