Painting with 4 stage HVLP

Hey Guys,

I have 10 interior 5 panel primed MDF doors that need to be painted. I have had fairly decent painted results with my HVLP but i'm wondering if anyone has advice. I own a Capspray CS9100 4 stage HVLP turbine with Maxum II Spray Gun. I usually water down the water based paint by 10-15%, with #4 tip, using a viscosity cup to get me in the ball park. But I can never quite get that great looking smooth paint job. I know my HVLP is a little underpowered and really for fine finishes but I know it can been done with pretty good results. I have used floetrol and other slowing/thinning agents with some success.

Anyone have advice on what I'm not doing right? Any help is appreciated!!!

Thanks Jocks,

Tim

The only way I've gotten a surface I was satisfied with using latex paint (I assume that's what you're using) was to lay down my coats, then go back over it with 320 or 400 grit paper and then hit it with General Finishes High Performance. That's a lot of work though, especially since your doors are paneled.

I've since abandoned latex for the occasional job where the client wants a painted surface, and gone with solvent based products. There are waterborne pigmented finishes too, I just like solvent based because I know how they'll behave.

For the record, I'm using a Fuji 4-stage and Fuji gun, which I would assume performs similarly to your setup.

I also have a capspray that I have used on few projects but never MDF. It was our first real paint system so everything we did was through trial and error…complete novices. We started with #3 and had a real difficult time with paint ( we were not thinning anything beyond 5-7.5%). Ended up buying the #4 and #5 for paint. Latex paint, we kept getting orange peel results. Eventually, we stopped using water base due to cleaning chore involved…for some reason we found it very time consuming. Good luck
