Product Description
Keep out water and moisture from the outside with the application of the Bostik Cementone Exterior Water Seal 5L. This water seal can be brushed onto any exterior surface like brickwork, asbestos, cement, cement renderings, roughcast, cast concrete, limestone, stonework, leather and even wood to stop rain from penetrating the surface. By reducing the water coming through, the seal can also improve insulation while resisting algae and mould growth and the retention of dirt. By using this product, you can increase the lifespan of stone, concrete, brick, terracotta and render especially, saving you plenty of time and money on repairs and restorations in the future.
