This is the New Foam that uses Environmentally Safe R134a Propellant and longer shelf life. Fresh Product Just Received! Special Notes: Keep in mind the expansion of the foam. A small amount behind a rock within 30 seconds will expand and start seeping out. Do a little at a time and go back if you need to fill in more. Purchase the amount of cans needed. Although every job is different, we found that a very small waterfall required about 3 cans. The larger the project purchase additional cans. Do not run water until foam starts to cure. Usually within 5 minutes however we find that waiting about 30 minutes will ensure that foam will not leak down the waterfall. Waterfall foam is not black but a silver/gray color. Have smaller gravel on hand and close by. This way when you are foaming you can throw some gravel into the foam to disguise and look more realistic.

Warnings: Always wear disposable gloves when working with waterfall foam. Always wear protective eyewear and clothes that you don't mind getting dirty Shipping
