Description
Bostik Water Seal Solvent Free water repellent penetrates deep into masonry to provide a water resistant barrier on porous surfaces. It is suitable for concrete, brick, stone and render, providing many years of protection, it can be applied by brush or spray.
The surface remains permeable to water vapour, allowing it to ‘breathe’, this prevents water being trapped. Water Seal Solvent Free is transparent and should not alter the appearance of the treated surface. Some surfaces may darken very slightly, so always carry out a test on a small area before full application.
