Stormdry Masonry Water Repellent Cream
Stormdry is a deeply penetrating water repellent cream for brick, stone, and concrete. Due to its cream-based formulation it is able to penetrate more deeply into masonry than standard liquid-applied water seal products.
Stormdry is based on proven silane/siloxane technology and works by lining the pores of the masonry rather than blocking them – allowing the wall to continue to breathe. This is in contrast to many standard brick sealer and stone sealer products which coat the masonry with a thin film.
Stormdry is easy to apply using a brush or roller and only a single coat application is required – many competing water repellent products require two coats.
Stormdry is the only colourless masonry water repellent treatment that carries BBA approval (cert. number 15/5198). After extensive testing to determine continued water-repellency after aggressive freeze-thaw and UV exposure, the BBA issued a certificate stating the product will remain effective as a masonry water repellent for 25 years.
By providing in-depth protection against moisture ingress, Stormdry is able to save energy. Tests carried out by the University of Portsmouth demonstrate that energy savings of up to 29% are possible by keeping walls dry using Stormdry. This is because dry walls are better insulators than wet walls.
