Product details
Provides long lasting roof leak protection
Highly effective gutter sealant
Resists cracking, UV and frost
No primer required
Contents - 1 x Bostik WATERSTOP Flexible Waterproof Coating 6KG - Grey
Bostik WATERSTOP Flexible Waterproof Coating is a high performance liquid rubber that immediately seals and protects surfaces to prevent damage from water and moisture.
It's perfect for quickly repairing leaks and for long lasting protection of flat roofs and gutters, as well as flashing, around roof lights and chimney stacks. It can also be used for sealing concrete foundations and walls.
This gutter sealant stops water travelling through porous, cracked or degraded substrates on both vertical and horizontal surfaces.
The highly flexible coating is easy-to-apply, quick drying and free from solvent, bitumen and isocyanates, meaning it's better for the environment.
It can be applied to many substrates by brush or roller without a primer, including concrete, stone, wood, metal, zinc, clay, tiles, slate, felt, polystyrene, and most plastics. However, it is not suitable for use on polyethylene & polypropylene plastics, or bitumen coatings.
Once applied, it instantly protects, even if it rains immediately after application. It is long lasting and resists cracking, UV and frost. Being flexible, it is not affected by temperature variations.
