Blue Thumb Handi-Foam Black Spray Foam - 24oz

24oz Professional Handi Foam

Handi Foam black spray foam expands & seals gaps between rocks and the liner. This diverts water over the rocks, instead of beneath them. Contractors use it during professional installations to simplify waterfall construction.
