Is there a special trick to spraying laquer primer? I bought the hot rod black primer , you know the flat black stuff, well ive sprayed it 3 times and each time it comes out looking like i rattle canned it, very uneven coats. Whats the secret? Ive cleaned the gun, ive tried different settings, ive tried thick to thin, i do not know why it will not spray even, the gun worked great on all the urathane primer and color i sprayed. HELP PLEASE!
Lacquer has to be cut very thin, like 1 part thinner to 1 part of primer. At least that's the way I remember it. One of the paint pros should be along to help shortly.
It is a napa brand siphon feed
About 35 psi
About 6 inches
In the high 70`s
I tried different distances, but none worked any better.
The can sayes 1 to 1, i tried slightly more and less , no change.
If the paint is uneven, then probably a combination of not enough material (open up your material feed adjustment) and an either an inconsistent or not enough overlap. Lacquer doesn't have near the coverage of the newer paints, with that and the combination of a non-hvlp gun and the high air pressure it's going to take a lot of concentration on your overlap to get good coverage. Are you applying single or double coats??? The gun and material used are probably also combining to give a very low efficeiency transfer rate.....
Im applying as many coats as i can, what im trying to do is cover the red paint in spots. I sprayed the whole car with a flattened red acrylic base coat to seal the car , then im painting below the beltline and the front section with scallops on the roof in the hot rod black. ill try the material feed next to see if that helps, im gonna go see it this morning to see what it looks like after it dried overnight.
I used lacquer for 35 years, and have had that problem many times, Lacquer is trickier to spray than enamel, so don't be discouraged.
Lacquer needs to go on wet every time. If you don't, you risk adhesion problems, among other things. seven things will help it to flow and level out. I use the first four, before I try the others:
1 Open the feed knob up to get more material.
2 Add more thinner. (up to 25%)
3 Move a little closer to the surface.
4 Make your spray passes a little slower.
These will usually cure the problem. If not try the others.
5 Make sure your "fan" adjustment isn't making the center of the pattern heavy, and the edges dry.
6 Overlap your spray pattern more.
7 Use a slower thinner, if you aren't already.
Go too far on any of these, and you may cause runs, and if you don't go far enough, you will get dry spots, which sounds like your problem.
Above all.....when you make a change, try it on a test panel until you like the result. I still do this every single time. You don't want to use the car as an experiment. Don't spray it until you like the setup you have.
Thanks guys now i feel better, im definatly getting dry spots, and ill adjust the fan to see if i can get a better result.
you may need a slower thinner HOT weather Hi humidity you may have to add retarder to it if blushing
