Teach me to paint with Air

For just interior paint, we just use electric sprayer.

Cleaning the gun out takes the longest

I just returned a Wagner sprayer to lowes that I bought for the same thing. It ended up being way more trouble than the time it saved. It took longer to prep and clean than just using a roller and pan.

You would likely need to thin it and depending on the paint may not be able to shoot it with an HVLP gun. Most interior painters use airless systems that can handle thick paints without issue due to their higher pressure. An HVLP gun produces a finer finish with less over spray and is ideal for more detailed work. If the 6CFM rating is the minimum requirement and that is what your compressor outputs then you may also run into some issues here. The CFM ratings is based on something like 15 seconds per minute duty cycle and 10 gallons isn't a whole lot of reserve for a continuous use tool like an HVLP gun trying to do an interior room, but something the size of a table might not present a problem. At the minimum, if you can get the gun to atomize the paint it will work for short periods of time then you may have to stop and let it build back up. If you start getting PSI drops from running out of air and your motor can't keep up this is going to affect your spray pattern and finish negatively. Since you already have the supplies, I would say just grab a piece of scrap and test it out and see. I shoot very thin fluid that has a viscosity similar to skim milk, so the above is just speculation.

The bigger problem you might have to worry about is keeping water, which condenses from the hot air, out of the paint. I run my air through 50 feet of hose then through a 50 ft steel pipe series of drops to catch the water plus inline desiccant dryers without issue here in the humid south. Also, don't use any hose that you used with oiled tools. The learning curve is not steep, but it takes a little practice to get the fluid/air/fan mix right and it can vary color to color or fluid type to fluid type.

All good info...my hopes are not high at this point.

Put lacquer thinner in the canister and spray it after you're finished

Using a standard hvlp always spray oils and they all will have to be thinned. I run from 38psi to about 45psi, depends on what paint. If you want to spray latex best thing is buy gun just for latex.

Side ?, anyone know who can fix a 50 HP recip air compressor in Baton Rouge ? Leaking a lot of water

Yes you can, look up Matt Lane on Youtube, he has a really video on spraying stuff and the most important thing...... how to keep your gun clean.

Not everything is shite at Harbor Freight, I have brad nailers, air compressors, framing nailers, clamps, hand saws pocket hole jig, some sockets that all works great, you have to do your research. The Paint guns actually get great reviews, its knowing how to use to them and how to clean them. MEK goes a long way in keeping them clean.
