Expandable black waterfall foam fills cracks, seals stone to liners and helps to stabilize stone set on slopes.
Rockin Foam is pH neutral and is safe for aquatic plants and animals. This black formula dries quickly, becoming tack free in 30 minutes.
Includes trigger assembly and straw for easy application.
Shake can, with trigger assembly attached, for 30 seconds. For best results use upside down (but foam can be dispensed at any angle). Fill gaps no more than 1/3 full to allow for expansion.

We prefer waterfall foam instead of mortar for most pond applications.
