JUHUAN Self-Spraying Waterproof is a high-performance, multi-purpose waterproof repair spray designed for fast sealing, leak repair, and surface protection in construction, tunnel engineering, civil defense facilities, and household applications.
Formulated with advanced polymer technology, it forms a durable waterproof barrier that helps seal prefabricated pipe connections, damaged joints, basement cracks, color steel roofs, and bathroom or kitchen pipes. Its convenient spray application allows targeted treatment of cracks, gaps, joints, and other areas where water leakage may occur.
