Water Seal
FAST-DRYING EXTERIOR WALLS & WOOD PROTECTOR
30812236
Product overview
Bostik Water Seal is a high-performance waterproofing solution designed to penetrate deeply into porous exterior walls, or exterior wood, forming a long-lasting, water-resistant barrier.
Ideal for use on external, porous materials such as masonry, brick, stone, terracotta, render and wood, it helps protect against moisture ingress, efflorescence and frost damage. This transparent treatment preserves the natural appearance of the surface, though slight darkening may occur on some materials—always test on a small, inconspicuous area before full application.
Bostik Water Seal allows surfaces to remain breathable by permitting water vapour to escape, preventing trapped moisture and associated damage. Easy-to-apply by brush or spray, it offers durable protection
