Sovereign 5L Weather-Chek Facade Cream - Long-Lasting Water Repellent for Brick, Stone & Masonry

Long-Lasting Water Repellent for Brick, Stone & Masonry

Sovereign Weather-Chek Façade Cream is a high-performance, one-coat treatment formulated to protect porous masonry surfaces from water ingress, damp penetration, and freeze-thaw damage. Its silane/siloxane-based cream formula penetrates deeply and cures to form a breathable, clear barrier — all without altering the appearance of the surface.

Ideal for brick, stone, concrete, render and mortar joints, Weather-Chek improves thermal efficiency, reduces heat loss, and guards against the damaging effects of moisture — including algae, mould, and salt bloom.
