- High Quality: The polyurethane waterproof sealants/coatings are water-based. The roof sealant provides excellent waterproofing, is long-lasting, and resists both low temperatures and heat. Using the leak repair waterproof coatings forms a durable protective film, helping to save time, money, and energy.

This waterproof coating easily adheres to surfaces, repairing holes, cracks, crevices, tears, and leaks, while sealing any cracked areas. The roof sealant also creates a protective waterproof layer in the treated area.
