Raincheck Water Seal 5 Litre Breathable, Colourless Waterproofer for Brick, Stone, Mortar & Concrete

Ready for use water seal which is developed using silicone hydrophobic technology, modifying the surface of the substrate and lining the pores, creating a water-resistant coating. Creates a breathable waterproof barrier, which still allows the wall to breathe.

It maintains the natural beauty of the substrate to which it is applied to. Highly versatile: it can be applied by either brush, roller or sprayer, and is water-repellent on stone, mortar and brick, with the ability to bridge hairline cracks. Offers stability against corrosion through its formula which minimises de-icing salts, and an impermeable protection against frost through its thermal insulation properties. UV-resistant formulation.
