What causes orange peel on lacquer finish?
Orange peel is the most universal defect in a sprayed finish. It is a bumpiness on the surface that resembles the skin of an orange, so hence the name. The most common cause of orange peel is an imbalance between the viscosity of the finish and the amount of air atomizing the liquid as it exits the gun.
How do you remove orange peel from lacquer?
Wet sand it with water and a little dish soap with 600 grit (if really rough) 800, 1000, or 1200 grit. Power buff it with a light rubbing compound. Clean, and then power glaze with 3m imperial micro-finishing compound of Meguiar’s 7 then 9. Lacquers are less prone to mil thickness cracking than C.V.’s.
How long should lacquer cure before rubbing out?
Shellac, solvent and water-based lacquers and two part finishes should cure at least a week. Oil-based varnishes and polyurethane should cure at least two weeks.

How do you restore a lacquer finish?
Use denatured alcohol on shellac, lacquer thinner on lacquer, a three-to-one mixture of alcohol and lacquer thinner on a lacquer/shellac mixture. To reamalgamate the finished surface, apply solvent along the grain of the wood in quick, long strokes; work quickly, and don’t let the brush get dry.
How long does it take lacquer to completely dry?
Lacquer dries in no more than half an hour, but it must cure completely between coats. Let the newly sprayed wood dry for about 48 hours, or as directed by the manufacturer.
How long does it take for lacquer to fully harden?
Lacquers do not require any additional molecules to become hard; once the solvent evaporates the resins solidify. That is why lacquers dry so quickly — within 5 to 10 minutes — and why the reintroduction of solvents (lacquer thinners) reconstitutes a dry, lacquered surface.
How can I Stop my orange peel from drying?
Answer from http://www.fujispray.com/orange-peel-help/: The number one issue for orange peel is that the material is too thick. To remedy this, add more thinner (or appropriate solvent) to the mixture. For fast drying products such as lacquers, you may also want to add a lacquer slowing agent such as Floetrol.
What causes orange peel when you spray paint?
Orange peel is the result of paint particles that are to large which causes an uneven, chunky finish. To fix orange peel you need to reduce the size of the paint particles that are sprayed (atomization!).
What should I do if my paint peels when I spray?
While increasing the air in a given amount of paint is one option, you may choose to thin the paint. To do this, add the proper reducer for the paint that you are spraying or ask about a thinner paint choice that may be available that still provides the proper performance for your work.
