Stormdry Masonry Protection Cream

Stormdry Masonry Protection Cream 3L, 5L & 20L

Stormdry Masonry Protection Cream is a BBA approved 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 brick sealer products.

It is supplied in the form of a deeply penetrating cream that is applied to the wall surface using a roller or brush. Once Stormdry has been applied to the wall surface in a single coat and will permeate deeply before curing to form a water-repellent barrier for a BBA approved 25 years.

25 Year Breathable Protection

It’s made up of carefully chosen silanes and siloxanes that line the masonry pores to form a water-repellent silicone matrix. Because it lines the pores rather than blocking them, the masonry is allowed to breathe, which decreases frost damage (spalling).

Stormdry Masonry Protection Cream is resistant to UV light and other forms of degradation, resulting in a life expectancy of 20 – 30 years.

Deeply Penetrating Penetrating Damp Protection

Traditional liquid-applied masonry water repellents can’t penetrate as far into masonry as Stormdry. As well as increasing life expectancy this also improves Stormdry’s crack-bridging ability.

Note: Larger cracks will still need to be filled as part of Stormdry application. Mortar lines may need to be repointed with a sand/cement or sand/lime mix incorporating Stormdry Repointing Additive.

Effective Rain Penetration Protection

Stormdry has been tested to BS EN ISO 15148:2002, it is effective on concrete, mortar, brick, and sandstone.

Note: Stormdry is formulated to penetrate deeply into masonry it can take up to two months after application for a noticeable “beading effect” to appear when rainfall hits the wall. Stormdry is resistant to rain after just 12 hours.

Improve Thermal Resistance – Verified By The Energy Saving Trust

Improving the thermal resistance of walls with traditional insulation is often difficult – particularly in older structures. Many homes and commercial properties in the UK & Ireland are built using single-skin walls, making them unsuitable for cavity wall insulation. Installing internal insulation may be inconvenient, whereas externally applied insulation is usually unsightly.

Stormdry offers a solution, porous masonry materials such as brick, stone, concrete and mortar are great insulators when they are wet. Stormdry blocks the water’s entry to the masonry, ensuring that its insulation is maintained all year round.

Tests carried out using Stormdry at the University of Portsmouth and subsequent SAP analysis showed reductions in solid wall thermal conductivity when Stormdry was applied. This has been verified in an independent report carried out by environmental consultants, Giraffe Innovation.
