Bostik Cementone Water Seal 5L

Product Details

Extend the life of outside areas and protect them against rain, damp and frost damage with this water seal by Bostik. You can apply it to surfaces such as concrete, brick, stone, slate, terracotta, render and wood. It's suitable for all types of building projects, from homes and offices to garden structures.

This sealant penetrates deep below the surface of your substrate and forms a water-resistant barrier to protect porous surfaces. Although it's waterproof, water vapour can still pass through it, so the treated materials can 'breathe' and moisture won't become trapped inside. Because it has a transparent finish, it won't alter the appearance of the area it's applied to, though it may darken a little on some surfaces, so do a small test patch first. As well as waterproofing, this product also helps to prevent condensation and efflorescence, keeping structures in great condition for longer.
