Product Description

Protect exterior walls from penetrating rain and damp with Stormdry Masonry Protection Cream Clear 5L. This ready-to-use, deeply penetrating silicone treatment creates a durable, water-repellent barrier within porous masonry while allowing the surface to remain breathable.

Suitable for use on unpainted brickwork, mortar, concrete, stone and compatible rendered surfaces, Stormdry is applied in a single coat using a brush, roller or airless sprayer. The thick white cream makes it easy to see where the product has been applied before it absorbs and cures to a clear, natural-looking finish without leaving a glossy surface coating.

By reducing the amount of rainwater absorbed through external walls, Stormdry helps protect against penetrating damp, frost damage and unwanted mould or algae growth. Keeping masonry drier may also improve its thermal performance and help reduce heat loss through external walls.

The 5-litre tub provides approximately 25m² coverage, depending on the porosity and condition of the surface. Stormdry is BBA approved to provide at least 25 years of protection, making it a reliable, long-lasting choice for homes, commercial buildings and renovation projects.
