What kind of paint gun should I use?


Hi all. I want to paint my detached garage and am thinking about doing the walls with a paint gun. I have an air compressor and was thinking about doing it with an air gun, but I've heard they have bad overspray. Can anyone point me in the right direction as to how to best paint my garage with a gun? Thanks!

Jesse

Rent an airless sprayer, you really can't spray latex with a siphon type gun.

Siphon gun, not what I would use, too much overspray. You could rent an airless for about the same.

You will be much better off renting an airless or just painting it by hand. The over spray can be controlled and limited on an airless paint sprayer by the tip size, the pressure control, and the way you move the gun. You are looking at using an HVLP sprayer, HVLP are made to be used for fine finish and light bodied materials and they are slow, a lot slower than spraying with an airless. When using latex paint with most HVLP you have to thin the latex to much and it compromises the molecular make up of the paint. The only real effective HVLP sprayers for latex are large turbine sprayers and air assisted sprayers. For your project an airless paint sprayer is the way to go. You can apply two coats of paint to an average building in a day or less.

Well, I'd rather buy than rent because I have a good amount of projects to use it for. However, I've seen that most of the airless sprayers are quite expensive. I just found this one though at sears and I can afford this. What do you think?

Those are no good. If you have a few projects and want to buy an airless sprayer you want to buy one that will at least spray .25 gallons a minute, 3000, piston pump, that will support up to at least a .015 tip. Spraytech and Graco make some good smaller units that are good to be used a couple of times a year.

I just found this same unit at harbor freight for $99. Do I need anything else besides paint or does it come with everything?

Any water based paint will and can be pumped with an airless sprayer, the size of the unit, is directly proportional to the speed at which you can move while spraying, say ft2/min or as rated gal/min the bigger the unit to more it sprays.

The wagner is an inexpensive system, so beware it won't last through alot of jobs without needing some kind of repair, afterall its only a 3/8 HP electric motor.

Personally I would be looking for the next step up, but thats me.

Yeah, I understand, but I'm just a homeowner, not a contractor. I'll be using this thing maybe twice a year.

I have to add this as it is sometimes overlooked or taken for granted, cleaning any unit is the key to its longevity, any paint left in that unit will destroy it.

I knew an older man years ago who painted his '53 Chevy with a "Black Flag" bug sprayer. Remember those? The red one's you put the liquid in a tank at the front of the unit, then pulled back on the handle, pushed air out and it siphoned the fluid out of the tank. NO joke, this happened. The car didn't look that bad, back then. He probably would have used an electric airless sprayer if they had them back then.
