I'm an old dog with lacquer, so I'm somewhat chagrined to have to ask. But...
I'm in the process of applying a more-coats-than-it-probably needs finish on a show piece, which is a walnut hollow form. I'm following my usual steps; sanding sealer, lots of fine sanding, application of 2-3 coats of clear, a bit more sanding...you get the drill. Normally, this works perfectly and most of the applications went off without a hitch, but these last few days extremely small bubbles have been appearing several hours after I've applied a coat. What's going on?
OK, here are a few factors in anticipation of your questions and comments:
- it has been incredibly cold here and I'm able to raise the temp in my studio with an electric space heater
- the humidity is pretty high
- I'm using Deft rattle can gloss
- I have not used any solvents to clean the surface during the process
I'm wondering if the wood itself has moisture in it that I didn't detect? Am I simply applying too much finish in too short of time? Could the heater (which is about three feet away) be causing the bubbles? Or is this just another episode of Twilight Zone?
