I am spraying a set of vaneties with a waterbased laquer from sherwin williams. It seems to be a pretty good product sprays and dries like laquer. My problem is on the finished ends after it dries I am getting stripes like it dries a different sheen and or shade. I know I coverd everything with the spray. Any one have a solution??????

What type of spray set up do you have? Is the material atomizing properly?

I've not used the waterbased lacquer but lacquers in general dry fast. This can both cause problems with overspray and sometimes the lacquer can dry on the tip causing problems with the spray pattern.

I have a husky hlvp gun from home depot its not to bad of a gun. It seem to be atomizing properly but the finish seams to be drying too fast I just tried putting on a heavier coat and turned down the air pressure a little and I am going to check it shortly. I have also been watching the tip for build up. Is there something I could use to slow the drying down? I have also had this problem when I spray latex.

Waterbased finishes are often problematic when spraying with any system that uses air. The air flow helps to dry the paint. HVLPs and conventional cup guns do better with solvent based coatings. An airless is prefered when spraying latex although cabinet spraying would require a bit of experience if spraying them with an airless.

Flood's flotrol and XIM's extender can help with latex paint but I don't know if they are compatible with your lacquer. What does the label say in regards to thinning?

It say you can thin up to 10% with water

You might try thinning it some.That may allow you to apply a wetter coat, just be carefull because it can also make it more apt to run :wall:
