I have an upcoming project where I'm going to need to be painting 7 interior doors and a few hundred feet of trim. Next summer I'm likely going to also have to start restaining the exterior of the house. I'm thinking it's time I upgrade from the brush and roller.
I'd love to get a air spray gun, but I'd have to get a large enough air compressor that a) would take up more of my limited space and b) likely never get used much (since my pancake compressor is more than enough for my nailing needs).
I see the big box stores now sell a variety of airless systems. Here's one on Amazon (picking it at random more than anything for reference:
My only experience with an airless sprayer was a $40-ish dollar hand-held one that I bought for doing a fence. It worked...but not really all that well. It sputtered and splattered more than it sprayed and we had to go over it all with a brush as we went to get an even coverage.
Granted, that was $40, so hoping the $300 airless systems are a bit better.
My question: What is the primary difference between the performance and usability of an air spray gun vs. the airless ones? What should I be looking for in an airless sprayer in terms of features?
