Item #RF26549 - 20 oz. Spray Can of Rockin' Foam

Spray foam in the cracks of your waterfall to stabilize the rocks and help prevent water loss due to seepage of water between the rocks.  Also guides water over the rocks instead of under and between so you can see all the water cascading down.  You get more for your money with Rockin' Foam than with leading competitors because it comes in a 20 oz. spray can that can be used over and over again.  Rockin' Foam's patented dispensing trigger allows the foam to be sprayed in any position to get to those hard-to-reach areas.  No need for a gun! Foam expands so there is less waste.  The foam is carbon black so there is less fading.  2 year shelf life.  Foam is black, water resistant and adheres to most surfaces.
