10 Best Brick Water Sealer

The Raincheck Universal Water Seal is a versatile liquid sealer designed for exterior use on bricks, wood, and stone. One of its strong points is breathability, which lets moisture escape from the surface, helping to prevent trapped water damage while still repelling rain effectively. Its water repellency is solid, described as water repellent rather than fully waterproof, making it suitable for general protection against moisture but not for heavy water immersion. The sealer is colorless and cures quickly, ensuring it doesn’t alter the look of your surfaces and provides a clean, natural finish.

Its durability impresses, promising up to 10 years of protection thanks to a high-strength silicone formulation with 5% active ingredient that penetrates evenly and even fills tiny cracks. The included adjustable pump sprayer makes application easier and more precise, which is helpful if you want a mist or spray option and consistent coverage.

This product fits well if you want a long-lasting, breathable, and easy-to-apply sealer for walls and outdoor surfaces that need water protection without changing their appearance. It may be less ideal if you require heavy-duty waterproofing or guaranteed UV shielding.

Stormdry Masonry Waterproofing Cream is designed to protect brick and other masonry surfaces like stone, mortar, and sandstone from water damage while still allowing them to breathe. This breathability prevents moisture from getting trapped inside walls, which can cause damage over time. The product provides a clear, colourless finish that won’t alter the look of your brickwork. It is BBA approved, meeting high standards for protecting against penetrating damp, and promises long-lasting protection for up to 25 years.

A key feature is the inclusion of the Stormdry Repointing Additive I, which enhances water repellency without blocking the natural breathability of mortar joints. This makes it suitable for older buildings or areas prone to heavy rain and flooding. The cream form is easy to apply as a single coat, saving time and effort.

If you want a reliable, long-lasting waterproof solution that allows your masonry to breathe and keeps your walls looking natural, Stormdry Masonry Waterproofing Cream is a solid choice. It is best suited for exterior brick or stone walls needing strong damp protection without sacrificing breathability.
