What is Aquadry Masonry Protection Cream?

Aquadry 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.

Aquadry 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.

Aquadry is easy to apply using a brush or roller and only a single coat application is required – many competing water repellent products require a minimum of two coats.

25-Year Durability

Aquadry 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 following 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 Aquadry. This is because dry walls are better insulators than wet walls.

Flood Protection

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

Aquadry – Preparation & Application

Aquadry should only be applied to dry, porous surfaces. It should not be applied over sealed or painted surfaces and is intended for above ground use only. Only apply when rain is not forecast for the next 24 hours. For the treatment to be successful it is essential to check all joint and roof connections. Hairline cracks up to 0.3mm can be ‘bridged’ by Aquadry, however, it may be necessary to fill cracks in brick/ stonework and repoint using a suitable sand/lime or sand/cement mortar incorporating Aquadry Repointing Additive. Dirty surfaces should be cleaned before the application of Aquadry Masonry Protection Cream to the recommendations given in BS8221-1:2000, “Code of practice for cleaning and surface repair of buildings. Cleaning of natural stones, brick, terracotta and concrete.” DO NOT USE DETERGENTS. Application to structures containing high levels of salt should be avoided.

Test Area

Aquadry has been formulated to be colourless once cured. However, very slight darkening may occur when it is applied to some substrates. Although this will usually fade over time, a small, representative and inconspicuous test area should always be treated before full treatment begins.


  • Carry out surface preparation

  • Use a brush to apply around details such as windows

  • Larger areas can be covered more quickly using roller application

  • 15-20 minutes after application, Aquadry starts to penetrate into the masonry

  • After 24-48 hours the wall will have returned to its original appearance

  • The masonry will be resistant to light rain after two hours.
