What is the best waterproofing coat?
The best waterproofing coating depends on the job:
- For leaking flat roofs and gutters, look for a flexible, weather-resistant coating that works on your particular surface. Bostik WATERSTOP Emergency Waterproof Coating provides an instant waterproof barrier and can be applied to materials including concrete, stone, wood, metal, clay, tiles, slate and felt, without needing a primer.
- For small cracks and hard-to-reach areas, Bostik WATERSTOP Repair Spray is a handy choice. Its flexible rubber formula creates a strong, waterproof coating and works on many outdoor materials, including roofing, metal, mineral surfaces, boards and wood. For larger roof and gutter leaks, a brush-on waterproof coating may be more suitable.
