Black Waterfall Spray Foam - 12oz Can with Nozzle - ON SALE

Product Features
Product Reviews
Exanding Waterfall Foam in a convenient 12oz can with handle nozzle. Use this waterfall foam to fill in gaps and crevices around and within rocks and boulders. Used to fill gaps and allow the water to roll over the rocks rather than behind. Dark color is easy to conceal by placing smaller gravel over while still wet. Pebbles will cure into place for a finished look.


  • Great for filling in gaps in your waterfall stones as well as attaching a waterfall stone to your waterfall filter.
  • Dries tack free in about 5 minutes depending on moisture and temperature conditions.
  • A 1" bead at room temperature can be cut within one hour.
  • Expands about 3-1 Ratio
  • Includes nozzle for spraying in tight locations
  • Expands to fill gaps and voids
  • Seals to most water garden materials including most liners, waterfall filter boxes, skimmers and more
  • 1/2" Bead Yields Approximately 340 Lineal Feet per 12oz. can
  • Be sure to buy Polyurethane Foam Cleaner (see below or click link to the left) to make clean up easy.
  • Buy Multiple cans and save!

Note: This is the New Foam that uses Environmentally Safe R134a Propellant and longer shelf life.

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.

  • Always wear disposable gloves when working with waterfall foam.
  • Always wear protective eye wear and clothes that you don't mind getting dirty
  • Store in a cool dry place out of direct sunlight and out of direct heat

Shipping Note: Foam cannot ship via air services since its an aerosol can under pressure. We can only ship via Ground service. No shipments to Alaska, Hawaii, Puerto Rico or Canada.
