Wind-driven rain on your home’s walls causes damp patches, blistering paint, an increased likelihood of mould growth and faster heat loss. The British Board of Agrément has certified that one coat of Stormdry Cream will protect walls from moisture ingress for at least 25 years. This waterproofing cream is ideal for use on exterior brick, stone, concrete, mortar, and sandstone surfaces.
This guide is for homeowners and property managers seeking to protect their brick, stone, and mortar walls from water damage using Stormdry Masonry Waterproofing Cream. The primary benefit is long-lasting protection against moisture ingress, potentially extending the lifespan of your exterior walls and reducing maintenance needs. Note that proper surface preparation is crucial for optimal performance, so ensure thorough cleaning before application.
