What type of paint sprayer has the least overspray?

If you don’t mind the noise, need to paint large surfaces quickly, and don’t want to mess with thinning the paint, then an airless sprayer is a good choice. For less overspray and a finer finish on interior projects, HVLP is a better choice.

Temperature. If the temperature is high then the overspray will dry quickly and will only be dust when it lands but cooler temps will cause the overspray to stay wet longer in the air and it can cause more damage.

What is the difference between HVLP and LVLP spray gun?

What is the difference between HVLP or LVLP spray systems? HVLP guns use more CFM and will require users to size their air compressor accordingly. On the other hand, LVLP atomizes better, sprays faster and lays down a better finish while using less CFM but high air pressure.

Can you spray paint with HVLP?

HVLP systems are not designed to spray heavier bodied latex paint. However, with some understanding you can successfully do so. Those systems force the fluid thru a small tip which breaks up the paint, but even then, a glass smooth surface is not going to be obtainable.
