Paint sprayers come in three main categories: pneumatic, airless, and HVLP. As the name implies, pneumatic sprayers use compressed air to apply paint. They require you to have a compressor for use and are prone to overspray. Airless sprayers pump paint out at high pressures, evenly coating the surface you’re painting. These are fairly versatile and can be used on both exterior surface, like fences and interior walls and ceilings. High Velocity Low Pressure, or HVLP, sprayers distribute paint using a steady stream of low-pressure air, creating a smooth finish. HVLP sprayers are great for projects such as cabinets, but typically don’t handle lacquers or varnishes well.
