The Wagner FLEXiO 4000 HVLP paint and stain sprayer is ideal for applying a consistent finish on a wide variety of interior and exterior painting projects such as walls, siding, kitchen cabinets, furniture, crafts, and more. This HVLP paint sprayer is designed for DIYers and homeowners looking for fast, versatile painting and staining results. The X-Boost turbine delivers the power to spray unthinned latex and oil-based paints, stains, and urethanes right from the can.
This versatile paint and stain sprayer includes two nozzles to help tackle multiple projects—the iSpray nozzle for broad surfaces like walls and ceilings, and the Detail Finish nozzle for a smooth, fine finish on cabinets, furniture, trim, and detailed work.
The FLEXiO 4000 features adjustable settings for material flow, pattern direction and width, and air power output to match project needs.
