Generic Black Rubber Lap Sealant, 10.5 Ounces

This black rubber sealant is recommended for sealing pond liner to skimmers and waterfall boxes, and other applications where two surfaces are bolted or compressed together and a waterproof seal is needed between them. It remains flexible, is fish-safe, and is even better than silicone! Drying time is approximately 45 minutes and it is fish safe after 24 hours.   Lap sealant is not a glue to hold things together. It is a waterproof seal between two things already being held together.    This listing is termed "generic" as the actual Lap Sealant sent may vary from the photo and brand name here.
