How Stormdry Can Help Protect Your Home from the Effects of Heavy Rain ?

Heavy downpours are an inevitable part of life in the UK. It can leave unprotected brickwork soaked, leading to peeling paint, salt efflorescence, mould, and higher heating costs. When rain drives into porous walls, the moisture lingers and slowly damages the fabric of your home. Stormdry protection is a modern weatherproofing solution that stops water penetration while allowing walls to breathe. By keeping rain out and letting moisture escape, it offers both weatherproofing and damp proofing for basements and external walls. This blog explains what Stormdry is, its benefits and how it shields your property from heavy rain.

What Is Stormdry?

Stormdry is a colourless, breathable masonry protection cream. It is applied in a single coat and cures into a water-repellent gel after soaking (up to 12 mm) into concrete, stone, or brick. Rainwater beads off the surface, but water vapour that is trapped in the wall can escape, allowing the wall to dry naturally. According to tests, it reduces heat loss through damp walls by roughly 4°C and water absorption by about 95%. The cream is approved by the British Board of Agrément (BBA), and it protects your home for twenty-five years after a single application.

4 Ways Stormdry Protects Your Home From The Effects Of Heavy Rain

Stormdry delivers comprehensive protection against heavy rain. Here are four specific ways it works:

1. Stops Penetrating Damp: Rainwater that would normally soak into masonry now beads on the surface. Treated walls absorb virtually no water, whereas untreated walls drink it in. By keeping walls dry, Stormdry prevents the freeze-thaw cycles that cause spalling and flaking.
2. Preserves Structural Strength: Stormdry keeps masonry dry and allows trapped vapour to evaporate; it reduces internal stresses and the risk of salt efflorescence. This makes it an effective water penetration prevention measure on exposed gables, parapets and chimney stacks.
3. Enhances Thermal Performance: A wet wall acts as a thermal bridge, drawing heat out of a building. Drying the wall with Stormdry reduces heat loss by up to four degrees and helps cavity insulation perform as intended. Homeowners can enjoy more stable indoor temperatures and lower energy bills. In basements, Stormdry can also make the space warmer and less prone to condensation.
4. Discourages Mould And Mildew: Damp conditions encourage fungal growth and can aggravate respiratory problems. By blocking rain but permitting evaporation, Stormdry lowers wall humidity. With drier surfaces, the likelihood of mould, mildew and musty odours decreases, improving indoor air quality and helping your family stay healthy.

How To Do Stormdry Treatment At Home?

Carrying out a Stormdry treatment is simple but requires proper preparation and attention to detail for long-lasting results. Here’s a quick step-by-step guide:

1. Inspect the Walls: Check for cracks, missing mortar or structural defects. These should be repaired before application so that the product can perform effectively.
2. Clean the Surface: Remove dirt, algae, loose paint or any existing coating that could prevent absorption. A clean, dry surface ensures deeper penetration of the cream.
3. Prepare the Area: Protect windows, plants, and paths from splashes using dust sheets or masking tape. Stormdry is best applied on a dry day when no rain is expected for at least 24 hours.
4. Apply the Cream: Using a brush or roller, spread the Stormdry cream evenly across the wall in a single, generous coat. For very porous surfaces, a second coat may be applied after the first has soaked in.
5. Allow to Cure: The cream begins repelling water within hours but fully cures over a couple of months. Once cured, it becomes an invisible, breathable barrier that provides lasting weather protection.
6. Maintain your Property: Check gutters, downpipes, and pointing regularly to keep moisture out. When combined with routine maintenance, Stormdry offers decades of reliable defence against the elements.

Regular inspection and proper application ensure that your property remains well-protected from water ingress, damp and frost damage for many years.
