RELN 2.8 oz. Silicone Superior Watertight Drainage Sealant, Black

RELN Drainage Sealant is 100% silicone and designed to be used with Channel Drains, Catch Basins and Sewer and Drainpipe to prevent leaks by creating watertight connections at each drainage assembly point. It is also designed to work on a variety of other exterior weather proofing applications and has a superior adhesion to most construction materials. For greater lamination to various plastics, we recommend to lightly sand areas where RELN Sealant will be applied. Once cured, it is a flexible form with a 50-year durability.
