The Aquascape Professional Foam Gun Applicator is the ideal waterfall foam sealant applicator for discriminating pond professionals. Foam sealant is used to redirect water and fill gaps in waterfalls and streams. The applicator allows for precise dispersion of foam, making it simple and easy to use. Designed to create an air- and moisture-tight seal between the gun and the can, the applicator provides maximum foam yield, and its efficient design minimizes waste during use. For use with Aquascape Professional Black Waterfall Foam.
