Looking for help diagnosing the cause of some air bubbles that are appearing in a lacquer finish.
-This only ever occurs on veneered plywood. White oak, walnut, alder, maple etc.
-One side of the panel will have no bubbles, the other side will. Size, location and frequency vary. Sometimes only one, sometimes 20+.
-They can occur over a stain or just as a clear coat.
-Spray pattern is consistent
-They only ever occur on the first coat
-It’s not consistent. I can go whole projects without having an issue only
for it to pop back up later.
Pictures are a stained Walnut panel.
Any thoughts are appreciated, I’ll answer any questions as timely as I can!
