Insucoat is a bitumen-based coating used for waterproofing, damp-proofing, and protection of various structures, including concrete foundations, built-up roofing systems, and retaining walls, by forming a tough, flexible film that resists water, salts, and moisture vapor. It is applied cold using a brush, roller, or spray, and adheres well to surfaces like concrete, brick, and wood, providing a durable protective barrier.
