Leakproof is a liquid adhesive designed to quickly form a water tight, leak-proof flexible seal on nearly any clean, dry surface. Intended for applications on surfaces such as aluminum, copper, galvanized, wood, plastic or vinyl. Leakproof expands and contracts depending on the substrate. Leakproof's liquid polymer technology eliminates curing time and provides for an instantaneous seal. It is available in 1-inch and 2-inch wide 24-foot rolls.
