Professional Waterfall Foam Applicator The Atlantic Water Gardens FallsFoam composite foam gun (HT300) is a professional-grade applicator designed for use with AWG FallsFoam and similar polyurethane expanding foam canisters. Unlike disposable straw-tip applicators, the HT300 composite gun provides precise, controlled foam deposition with an adjustable flow valve — allowing the installer to apply a thin bead, a thick fill, or anything in between with a single trigger pull. This level of control is essential in waterfall and stream installations where foam must fill specific voids and channel water flow precisely without overflow onto visible rock surfaces. Construction The HT300 composite body is lighter than metal gun alternatives while maintaining the rigidity and valve precision of professional foam guns. The composite material also resists solvent attack from foam cleaner chemicals, extending service life through repeated cleaning cycles. The ergonomic handle and trigger reduce hand fatigue during extended foam application sessions on large waterfall projects. Maintenance Flush with the AWG foam gun cleaner (12 oz can, sold separately) immediately after every use. Store with the cleaner can attached between foam sessions to prevent foam cure inside the gun valve.
