Everbuild 408 Super Seal (formerly Exterior Wall Seal) is a high-performance, solvent based, transparent water-repellent, specially formulated to provide a water-repellent finish and prevent attack by water penetration on porous substrates such as brick, stone, concrete, plaster, plasterboard, pebbledash, rendering, porous tiling, grouting etc.

Super Seal penetrates deep into the treated area and actually chemically bonds to the surface, providing effective water repellency for many years. It is unaffected by ultraviolet light and offers improved water beading when compared to other traditional solvent based products.
