Stormdry Masonry Protection Cream
Certifications and Accreditations
We formulated Stormdry Masonry Protection Cream for one reason only: to keep walls warm. We protect brick walls from moisture damage because it’s an effective way to protect and enhance the insulative properties of cavity walls and solid walls.
We don’t make claims – we report results.
Stormdry Masonry Protection Cream has been tested to EN ISO 15148: 2002 (E) as effective on concrete, mortar, brick, and sandstone.
To test this claim, the British Board of Agrément conducted a series of advanced tests. (Test Report No. 53232)
To test Stormdry Cream’s breathability, tests were carried out in accordance with BS EN 12572 : 2001 Hydrothermal Performance of Building Materials and Products – Determination of water vapour transmission properties. Water vapour was found to have successfully transmitted through a Stormdry Cream treated brick wall.
To test Stormdry Cream’s water repellency, tests were carried out in accordance with BS EN ISO 15148 : 2002 Hygrothermal performance of materials and products – Determination of water absorption coefficient by partial immersion. These tests were carried out before and after the accelerated ageing treatment. In comparison to untreated samples, Stormdry Cream was found to be fully water repellant both before and after the accelerated ageing treatment.
To determine how long Stormdry Cream treated surfaces took to dry, brick samples were immersed in water and sealed in a vapour impermeable membrane, leaving only the Stormdry Cream coated side of the surface exposed. Moisture on the Stormdry treated surface dried much quicker than on an untreated surface.
Both a Stormdry Cream treated wall and an untreated wall were exposed to accelerated ageing tests. Multiple freeze-thaw cycles to simulate seasonal temperature change and UV exposure to simulate outdoor sunlight exposure (in accordance with BS EN ISO 4892-3 : 2000 Plastics – Methods of exposure to laboratory light sources) were used. After a simulated 25 years of weathering, the Stormdry Cream coating remained undamaged and functional.
Samples of the various substrates prepared for the capillary absorption test were used to calculate the depth of penetration. The samples were broken in half and wetted with water. They showed that Stormdry Cream had penetrated Fletton brick to a depth of 12 mm.
Stormdry Masonry Protection Cream has been awarded the CE and UKCA markings under the British Standard EN 1504-2:2005: Products and systems for the protection and repair of concrete structures.
Stormdry Cream was certified as effective for concrete structures in:
Freeze-thaw resistance
Penetration depth
Breathability
Water absorption
Alkali resistance
Warringtonhouse, a fire testing, inspection and certification house, tested a Stormdry Cream under British Standard EN 13501-1.
After extensive testing, it received an A1 classification as a non-combustible material. This is the highest possible rating.
The A1 rating certifies that Stormdry Cream can be safely specified for use on properties that extend above 18 metres.
