Can I paint a bathtub with a 2HP aircompressor? What about furniture?
I read a web article on how to paint a bathtub, and mail ordered for a 2hp / 150 psi air compressor (and HPLV spray gun). Since then I read other articles stating that you need a 5 hp compressor to paint. Is 5 HP just for painting large stuff such as houses, decks, cars, etc? The shipping costs are a lot. Arghh. Thanks for any input!
The size of the motor only governs how quickly the cylinder fills and how long it takes to re-fill, when pressure the drops.
The cylinder size is the more important part of the compressor. The larger the cylinder the less often the gun pressure drops, with the gun and compressor both being regulated. I don’t know, but if I could get away with using a 2HP compressor, as opposed to a 5HP then I wouldn’t hesitate (cheaper electricity costs). You’ll find that it is more-so the technique, along with a steady light pressure and, not necessarily the power of the compressor motor, which governs the end result.
I had a 2HP/ 150psi compressor with a cylinder which measured approx 2′6″ in length by approx 12″ in diameter. I found that it did most things, including spraying motor cars. I simply regulated it so that the compressor wasn’t constantly kicking in.
There is a useful web-site which describes how best to do the job. I don’t know - you might have already accessed the site.
The first link describes how to paint a tub using the gun, the second how to keep the gun clean - just as important.
The site also has an internal search engine, for finding anything else (DIY) that you might be interested in, including furniture.

Hi, there is no hplv it is hvlp. you need 60 to 80 pounds of psi. to paint with.some guns are low psi .like 35 to 45 psi.Painting houses they use air lase .painters. cars they use HVLP guns there a lot of money 600 hundred dollars and up.,good luck.
