GREAT STUFF™ Pond & Stone is a polyurethane-based insulating foam sealant designed for use in water features. By expanding to fill gaps and cracks, it works as a waterproof sealant to help direct the flow of water in waterfall, pond and streambed construction. This version of Great Stuff expanding foam also offers water resistance. It is not meant to be in constant direct contact with water but is suitable for outside locations where exposure to water is likely. Examples include sealing around external piping and faucets, basement areas, and electrical and cable lines. TotalPond's Waterfall Foam Sealant is a one-component, polyurethane foam, moisture-cured mixture used to fill, seal, and bond rocks for waterfall construction. Waterfall Foam Sealant is a single-component polyurethane black foam that fills gaps and ensures efficient water flow over rocks. Spray Foam Around Windows and Doors is A-Ok But it can actually push the jamb inward, making them impossible to open. Avoid this by using minimal expanding foam. It's formulated to fill the space around windows and doors without excess expansion. Look for cans labeled for use on windows and doors.

Put 'em on, saturate 'em with acetone, wait a couple of minutes, peel 'em off - the gunk should be removeable by then. Remember, it's only nail polish remover, and is skin-safe as long as you aren't swimming in the stuff.

Wipe excess spray foam insulation from the skin while the foam is still wet. Wipe the area with acetone. Wash hands thoroughly with soap and water. Rub the dried foam with a pumice stone to wear as much of the foam away as possible. Apply lanolin or petroleum jelly generously to the affected area.

Use a putty knife or similar tool, if necessary, to help the sealant penetrate the cracks and ensure that each crack is covered. Allow the sealant sufficient time to dry completely. Sand the sealant, if necessary, to create an even surface within the fountain. Apply waterproofing concrete sealant or paint if desired.

Open cell spray foam insulation will still dry completely after getting wet. In addition, because spray foam is not a “food” for mold, there is little danger of mold becoming a problem even if it gets wet. Closed cell foams also do not absorb water, which is very beneficial in flooding zones.
