Bond It Waterseal Masonry Waterproofer 25L

Bond It Waterseal Masonry Waterproofer 25L is a premium exterior masonry treatment designed to provide long-lasting water repellence for brick, stone, and concrete surfaces. This high-performance breathable waterproofer protects exterior walls from rain penetration while still allowing moisture vapour to escape, helping maintain the integrity and appearance of the building fabric.

Ideal for professional and domestic use, Bond It Waterseal helps reduce water-related damage caused by rain, damp, and frost. It forms an invisible protective barrier that does not alter the natural appearance of masonry, while also assisting in reducing heat loss associated with damp walls.

Avoid splashing or misting onto surrounding surfaces such as windows, painted areas, vehicles, plants, or ponds.

Performance & Protection

The advanced water-repellent formulation penetrates masonry surfaces to provide long-term protection against water ingress, frost damage, and weathering. By reducing moisture retention, it can also help improve energy efficiency by minimising heat loss associated with damp walls.
