With the correct tip and pin set, it will push latex(waterborne) wall an ceiling paint. But with the way the paint is atomized , flow rates and small cup size, it would be a pretty slow way to paint ceilings or walls. It would be faster the old school way, brush an roll. For cabinets, mill work and furniture it will work fine. Another thing with these type of sprayers is that with any fast drying product it can cause webbing (product drying at the tip) as the unit blows pretty hot air. Adding a second length of hose helped with that but only marginally.
lol,,,Ive been painting houses for as long an you have managed to avoid it...........
Lucky you.
