Waterproof Wall & Pipe Hole Sealant Solid Glue

Reliable waterproof sealing for wall, pipe and AC holes

- This solid glue sealant is designed to quickly close gaps and holes around sewer pipes, wall penetrations and air conditioning openings, helping you stop unwanted water, drafts and odors with a clean, durable finish.

Formulated as a dense, solid sealant block, it can be shaped and pressed directly into cracks, gaps and holes in masonry, concrete, brick, tile and around pipe sleeves. Once applied, it adheres firmly to the surrounding surface, forming a continuous waterproof barrier that helps prevent seepage and moisture ingress. Its compact size (approx. 10 × 5 × 2 cm) makes it easy to handle and store in a toolbox or household repair kit, ready for quick maintenance tasks throughout the home.

This sealant is suitable for a variety of indoor and semi‑protected outdoor applications, such as sealing around sewer pipe entries, closing unused air conditioning wall holes, repairing small wall penetrations caused by cables, and reinforcing existing seals that have started to crack. The solid formulation offers stable performance and is designed to maintain its shape and adhesion over time once correctly installed.

• Versatile use for wall holes, sewer pipe gaps and air conditioning openings with one product.
