Yorkshire Timber & Builders Merchants are holding a Stormdry demonstration on Wednesday 8th March! We would love to see you come down and take advantage of our demonstration!

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.

It’s 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.

It 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.

25-Year Durability

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 with the followiung durability statement:

the product will remain effective as a masonry water repellent for 25 years.

Energy Saving

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.

Flood Protection

Used in conjunction with Stormdry Repointing Additive No.2, Stormdry is able to increase the flood resistance of masonry without altering its appearance.
