What paint sprayer doesn't require thinning the paint?

What paint sprayer does not require thinning the paint is primarily airless paint sprayer, which is designed to spray thick latex and oil-based paints without thinning, unlike HVLP and LVLP spray guns that often require thinning for proper atomization. Airless sprayers like Graco Magnum X5, X7, Titan ControlMax, and professional Graco 390 and 490 use high-pressure pump up to 3000 PSI to force thick paint through small tip, atomizing it without needing to thin, so you can spray unthinned latex house paint, primers, stains, and even some elastomeric coatings directly from 1 or 5-gallon bucket, which is major advantage for house painting, fences, and decks. HVLP and LVLP spray guns, which operate at low pressure, typically require thinning latex paint 10 to 20 percent with water or oil paint with mineral spirits to achieve proper viscosity around 20 to 30 seconds in viscosity cup, otherwise they cause orange peel and clogging. So if you want to avoid thinning, choose airless sprayer. Some high-end HVLP turbine systems like Fuji Q5 can spray thicker materials with less thinning, but still often need some thinning. For absolute no thinning, airless is best, with Graco Magnum series being most popular homeowner airless that sprays unthinned latex.
