What type of paint is best for an HVLP sprayer depends on project, but HVLP sprayers work best with paints that can be thinned to proper viscosity and atomize finely for smooth finish, with certain paints ideal. For automotive painting, best paints for HVLP are solvent-based and waterborne basecoats, clearcoats, single-stage urethanes, and primers specifically formulated for automotive refinishing, with 1.3 to 1.4 mm tip for base and clear and 1.7 to 1.8 mm for primer, providing excellent atomization and glossy finish. For woodworking and furniture, best paints for HVLP are lacquers, varnishes, conversion varnishes, shellac, and water-based acrylics thinned to 20 to 30 seconds in viscosity cup, which spray smoothly without brush marks. For house trim and cabinets, best paints are water-based acrylic enamels and alkyd enamels thinned 10 to 15 percent. HVLP does not handle thick unthinned latex house paint well, as it is too thick and causes orange peel, so for thick latex you need airless, not HVLP. Oil-based enamels and stains work well in HVLP when thinned appropriately. So best paints for HVLP are thin to medium viscosity coatings like automotive basecoat and clearcoat, lacquers, varnishes, and thinned enamels that atomize finely, while thick latex house paint is not best for HVLP and requires airless.
