What kind of sprayer to use with Behr paint?

If you own a compressor, or plan on buying one, you will be looking for a general purpose sprayer that likely has the paint container sitting below the nozzle, since most gravity-fed sprayers (can above the nozzle) are for thin paints and varnishes used in automotive detailing applications. The important thing is to read the specifications for the sprayer to determine if latex paints can be used. Once you have found one or more that state they can be used with latex, ensure that the compressor you will be using has the required scf rating to deliver the latex paint through the sprayer. Some sprayers may require as little as 2 scf @ 40 psi which is something virtually every compressor can deliver while other latex-capable sprayers may require a more powerful compressor. Of course, you will also have to use a thinner in the latex paint regardless of the sprayer you choose.

ANSWER: Actually, you can not use a cup gun to spray latex paint with a standard air compressor. The latex paint requires either a high amount of air or high pressure to atomize the paint. This can be done with an HVLP (High Volume Low Pressure) sprayer and gun, a gravity feed gun with a projector set that handles thicker fluids, or an airless paint sprayer that uses a piston or diaphragm to push the paint through a hose, to a gun where the paint will be atomized by a spray tip.
