Gonna start painting kitchen cabinets and inside trim/doors and looking for something decent. I've read several sites on pros/cons of HVLP, Airless, Air Assisted, etc... I used one of the Wagner ones many years ago to paint the outside of my house, but dont think it would have done well on interior stuff.

I recommend doing it by hand, and not spraying.

You basically have to turn the room into a spray booth with clean air in and a way to exhaust that air. Clean and vacuum (exhaust air has to be plumbed outside the room) thoroughly. Any dust or dirt left in the room will be attracted to the new finish. Good luck..it can be done, but I'm not sure the end result is worth the effort.

If the house is empty, then use an airless and spray. Otherwise roll the doors and cabinets and brush the trim. I've taken the doors off including cabinet doors and sprayed in the garage before.
Harbor freight has a decent sprayer for around 200 bucks. Use a short nap roller for the doors and cabinets.

Hire someone

Graco LTS-15 or X-5

Hire TFFer Darryl Roach - 817-475-3732.

The cheap Harbor Freight cup gun works fine for the money in a home use environment. No need to go buy a more expensive gun for a 1-3 time use. Hell I use one at work for oddball colors I don't spray very often. Other than that I'm spraying with a Binks or SATA. Graco isn't bad. Used one for years.
But for a home project. No need to spend a **** ton of money. Dust is the enemy of any paint job. In the case of kitchens, so is grease. Depending on the kitchen design. It normally isn't too difficult to contain any over spray.
Turn off any nearby pilot light.

After I thought about it. A cup gun may not work very well on cabinets. Most of my guns are on pressure pots. I don't have to deal with an annoying cup to try to get in tight spaces.

An airless is the right tool for the job. But you need to know how to use one very well and that only comes with years of experience. JP had the best suggestion.

An airless ain't that hard to figure out. At least it wasn't for me. I've only used one like 2-3 times. Prep would be the hardest part. Anyone really can spray if they have common sense.

You can spay a cat or dog with paint?

Spraying walls and fences is nothing like spraying cabinets. Even the best painters still get runs or orange peel finishes on cabinets. Trust me, I've been doing this for 25 years.

Well I'm not spraying walls, fences, or cabinets. I mean I have in the past. If anything that's where I have the least experience. Home repair type stuff. All my 20+ years are in industrial settings. So I'll have to conceed there. For me, I had no problem when I did. To me an airless is probably the easiest to use. But at the same time, there isn't much I haven't sprayed. There isn't many coatings I haven't sprayed. There isn't really any type of equipment I haven't used. So I should probably take that into consideration.

I may have to hire Daryl, but I told wife I would try it in a junk door and see how it looks before I tackle the entire project

You dont want to hand paint cabinets, you definitely want a sprayer. I painted apartments through college and we painted cabinets all the time. Hand paint or rolling cabinets is going to leave lines and will take a ton of coats. Get a sprayer, Graco is great. Rent it from a Home Depot for 2 days, it is cheap. Do the prep work (cover counter tops etc) it is a pain but absolutely worth it in the end.

You first coat needs to be Kilz, after that dries then first coat of paint, depending on the color change a third coat maybe needed but you can likely do all 3 coats in one day.

Do not start hand painting cabinets because you dont want to do the prep work for spraying, you will regret that decision (unless these cabinets are in your garage or utility room where no one is going to see them).
