Oil base through HVLP question
 
Hello,

Here is the situation, I had my painters who have been doing some texture and patch work for me (so far work has been really good) shoot my new kitchen cabinets. Well let's say the results were less than what I was expecting. First coat had a lot of runs and generally horrible results. I had bought the paint, BM satin Impervo. After much round and round they scrapped and sanded and reshot. This time SW oil base enamel. The results looked much better no runs, everything looked good when wet. I paid them, they left, paint cured and now there were some pretty nasty scratches from sanding on the door faces. :furious:


I didn't want those guys to mess with it anymore so I am tackling it myself. Not real happy about it, but it is what it is at this point. :censored:

Here is the current situation, the body of the cabinets are passible the doors need re shooting. I have set up everything in my garage and have already shot a coupe of coats, finish is just not there yet. Close, but not yet as smooth as the airless work they did.

I am comfortable with my HVLP guns (used several times and have done some auto shooting) and feel more confident using these than renting an airless (I've never used one). I have an older devilbiss auto gun (I think 1.3ish tip), and 2 lesser gravity fed guns 1.4 and 2.0 tips.

I have been shooting with the gravity feed guns and the results are ok, just not as smooth as I would like.

After spraying and still wet, the paint has slight pebbling to it, not orange peel just larger "drops" of paint.

I am shooting SW oil enamel, black thinned about 5% with thinner (per spec sheet).

I feel good about my rig set up (air, gun tuning). I think the paint is not thinned enough. I have never shot oil before just BC/CC and auto enamel. I am worried thinning more and messing with the sheen. Does anyone have any advice on thinning SW oil enamel? Does it usually take a little thinner than the 5%?

I sanded all the doors down with fine scotch bright pads and then wet sanded with 600 to really smooth finish ready to recoat.


Thanks!

Perhaps..... Penetrol?

Maybe I'll experiment with a thinner/p-trol mix.

Yep,

A little extra dash of thinner and a couple splashes of penetrol did the trick!
