Construct a stunning pond waterfall or stream bed masterpiece like the professionals. The TetraPond Waterfall Foam Sealant is an essential part of pond waterfall construction and is the design secret behind waterfalls with personality. Expanding black foam helps keep rockwork in place and fills in gaps for a watertight seal. Moving water travels over rockwork rather than through it to maintain dynamic water flow. Includes foam applicator nozzle for direct and precise application. The TetraPond Waterfall Foam Sealant dries tack-free in about five minutes and can be trimmed with a knife in one hour. Cures in 12 to 24 hours. Safe for fish and plants. 12 ounce can.
