The 3 Jet Combo Sprayer saves valuable time and money allowing for a smooth seamless transition from wall to ceiling plaster applications. Made of durable materials and made in the USA, our sprayers are manufactured from the best quality materials and designed with comfort and durability in mind. The stainless steel hopper is extremely durable and easy to clean. The extension handle and hopper handle is designed to give you a stronger grip, good control, balance and comfort while you are applying material.The Combo Plaster Sprayer is almost as fast as our 4 hole wall sprayer, and you have the choice to use 1, 2 or 3 jets. This allows the sprayer to work efficiently with smaller compressors and makes detail work easier on walls and ceilings.It comes with two sizes of jets and the accessories to adjust it to various application needs. The handle can be use short for confined spaces and long for best comfort.We recommend a 7 cfm @ 90 psi compressor but many of our users have been happy with their smaller 110 volt compressors by adjusting the jet configuration to match their compressor. Larger air storage tanks (20+ gallons) are also a helpful thing. Another customer told us about borrowing a second small compressor and adding the output with his for plastering his home.
