Thompson's One Coat Water Seal Ultra protects against water damage in one coat
The silicone micro emulsion effectively penetrates below the surface of porous materials carrying waterproofing resins deep into the pores of the substrate
The breathable waterproofing membrane allows moisture vapor inside the substrate to evaporate whilst protecting against water penetration and damage
The invisible membrane is protected from ultraviolet light and is long lasting even under heavy moisture conditions
Assuming application instructions and coverage guidelines are adhered to it provides effective water repellency for years in just one coat
Suitable for use on a range of cementitious surfaces such as brickwork, pointing, rendering, stone, concrete and plaster
For exterior use only
