Black Foam Sealant is a great product used to fill gaps and spaces in between rocks, edging where the liner meets rock, and other areas of concern for leaks. It is an aerasol can with an applicator straw that directly applies a black foam to the desired area. The foam expands immediately to fill the space, hardens in about 30 seconds, and is permanently amalgamated after a few hours of curing. Black Foam Sealant is a simple and quick solution for gap filling!
