The 1.5 Gallon Pump-Up Bulletâ„¢ Foamer Pro is a portable foam applicator for applying pre-diluted, foaming chemicals to any surface as wet, clinging foam. This professional model features a heavy-duty hose, trigger gun, and extension wand and combines the many advantages of foam cleaning with the familiar ease and portability of a typical pump-up sprayer. The adjustable Bulletâ„¢ foam nozzle draws in atmospheric air to create a wet, clinging foam and projects a wide pattern or narrow stream.
