Stormdry – Masonry Protection Cream
Stormdry Masonry Protection Cream is a deeply penetrating water-repellent silicone cream for the protection of masonry. The thick, white cream is ready to use and applied by brush, roller or airless spray. It penetrates into brickwork, masonry, mortar and concrete, where it will cure to a colourless, natural finish, lasting for over 25 years. Stormdry Cream can help improve the energy efficiency of dwellings by reducing heat loss.
- Deeply penetrating
- Single coat application
- Durable – Agrément Certified to last 25 years
- Verified by the Energy Saving Trust
Stormdry® Cream has been shown to be effective on common masonry materials including clay bricks, various sandstones, sand-based mortars and dense concrete blocks. Details of substrate compatibility and performance are available on request from our technical department.
A small proportion of masonry materials are unsuitable for treatment due to their particular surface chemistry. These include pure limestone and some types of lower density non-facing concrete blocks which are generally used for internal wall construction. We are able to offer alternative treatments suitable for these materials.
Always try a test area first to determine suitability of the substrate.
Stormdry® Cream can be used to protect cavity wall insulation from the effects of penetrating damp. It is recommended to apply Stormdry® Cream before installing cavity wall insulation. In cases of CWI failure damp insulation should be removed. The breathable nature of Stormdry® Cream will allow any residual dampness from the wall to dry out.
Stormdry® 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.
Stormdry can be used as a primer prior to the application of Stormdry AG-Coat.
