Bostik Waterstop Flexible Waterproof Coating 14kg

Bostik WATERSTOP Flexible Waterproof Coating is a high performance, flexible waterproof coating 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, gutters, flashing, around roof lights and chimney stacks. It can also be used for sealing concrete foundations and walls. Bostik WATERSTOP Flexible Waterproof Coating 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 without a primer: 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.

Key Features

  • Provides long lasting protection against leaks
  • Can be applied to wet or dry surfaces
  • Resists cracking, UV, frost & temperature variations

Coverage: 2.3kg to 3.1kg per m2 (approx.) When applied in two coats, each at 1.5mm thickness to achieve minimum 3mm dried film thickness. (depending on substrate, application technique and performance requirements)
