Stormdry Masonry Protection Cream is a professional-grade water repellent ideal for homeowners and contractors looking to protect brick, stone, and mortar surfaces from penetrating damp. The product's key benefit is its ability to create a long-lasting, breathable barrier in a single coat that significantly reduces moisture absorption, thereby preventing issues like mould, efflorescence, and heat loss. While it is a highly effective solution, it requires careful surface preparation and is specifically formulated for masonry, meaning it is not suitable for non-porous surfaces or as a substitute for fixing structural leaks.

It is generally recommended to apply Stormdry after any painting or to use it on bare masonry, as it is designed to penetrate the surface material directly.
The product begins to show water-repellent properties as it cures, typically within 24 to 48 hours depending on weather conditions.
Yes, it is highly effective on porous natural stones, including limestone and sandstone, provided they are clean and dry.
Once fully cured, Stormdry is virtually invisible and will not alter the texture or colour of your masonry.
The masonry should be as dry as possible to allow the cream to penetrate; it will not work effectively if applied to saturated or actively wet surfaces.
Once dry, it is inert. However, take care to cover or protect surrounding vegetation during the application process.
This is likely excess product that did not penetrate. It will disappear naturally with exposure to weather, but can be brushed off once fully dry.
Ensure consistent saturation. If the surface is highly porous, it may absorb more cream, requiring a more uniform application technique.
Before application, ensure the masonry surface is clean, dry, and free from loose debris, mortar droppings, or existing coatings that might block penetration. You can apply the cream using a brush, roller, or airless spray equipment. Aim for a coverage rate that ensures the masonry is saturated but not dripping. For best compatibility, test a small, inconspicuous area first. During the curing process, keep the area dry for at least 24 hours to ensure the cream fully absorbs into the substrate. Store the remaining product in its original, sealed container in a cool, frost-free location.
