This Putty is a heavy-duty, waterproof sealing solution made for plumbing and HVAC professionals as well as DIY enthusiasts. It seals sink drains, tubs, showers, pipe joints, and HVAC ducts with a secure and long-lasting bond. The pliable texture makes it easy to apply—just clean the surface, press the putty into place, and allow 3–7 days to air-dry depending on conditions. Made with non-toxic, durable materials, this white epoxy putty also acts as a reliable cement crack filler and mending solution, helping prevent leaks, drafts, and unpleasant odors in both home and commercial environments.
