Consult label and material safety data sheet for more information.
Stormdry Masonry Protection Cream should be applied to dry, porous surfaces. It should not be applied over sealed or painted surfaces and is intended for above ground use only.
Apply when rain is not forecast for the next 24 hours and before winter sets in.
For the treatment to be successful it is necessary to check all joint and roof connections.
Hairline cracks up to 0.3 mm can be ‘bridged’ by Stormdry Masonry Protection Cream, however, it may be necessary to fill wider cracks in brick / stonework and re-point using a suitable cement or a lime based mortar.
After any re-pointing work it is advisable to wait 1 - 2 weeks for the mortar to cure before applying Stormdry Masonry Protection Cream.
Dirty surfaces should be cleaned before the application of Stormdry Masonry Protection Cream to the recommendations given in BS 8221-1:2000, (Code of practice for cleaning and surface repair of buildings. Cleaning of natural stones, brick, terracotta and concrete.)
Remove any loose mortar, dust etc., using a masonry brush.
When biological growth such as moss, algae or lichen needs to be removed, apply one of our Masonry Biocide Products in accordance with instructions.
Application to structures containing high levels of salt should be avoided.
Stormdry Masonry Protection Cream has been formulated to be colourless once cured.
Slight darkening may occur when it is applied to some substrates, which will usually fade over time.
It is recommended that a small test area is treated before full application begins.
Apply by brush, roller or spray. Larger areas can be covered more quickly using roller application.
Details such as around windows are best covered by brush. Care should be taken to ensure that Stormdry Masonry Protection Cream does not splash onto glass, paintwork, plants, etc. Any splashes should be cleaned away with warm soapy water.
Stormdry Masonry Protection Cream appears white immediately after treatment – making it easy to tell which areas have been treated.
After 15 - 20 minutes from application, Stormdry Masonry Protection Cream starts to penetrate into the masonry and the whiteness will fade.
After 24 - 48 hours the wall will have returned to its original appearance.
As Stormdry Masonry Protection Cream is formulated to penetrate deeply into masonry it can take up to two months for a noticeable 'beading effect' to appear when rainfall strikes the wall.
The masonry will be resistant to light rain after 2 - 4 hours.
After application, tools should be cleaned immediately with warm, soapy water.
Stormdry Masonry Protection Cream can be over-painted with water-based masonry paint, provided this is done within 3 – 10 days of application. After this time, a solvent based paint can be applied.
It is advisable that a test is carried out in a small area prior to full application to determine product compatibility.
Approx 5m² per litre, however this can be greatly reduced depending of the porosity of the substrate. Single coat application.

Q) Can I apply Stormdry in Winter?
A) Technically yes. As Stormdry Masonry Protection Cream is breathable, it can be applied to damp walls as it will allow moisture to evaporate and exit the wall.
