Shellac in the Bathroom?

Having seen just how badly standing liquid water can damage a Shellac finish, I wouls really shy away frim using it in kitchen or bathroom where steam is around and where water can fly.I think even just a few thin coats of some wipe on poly (the only way I like to use it) would seal it and you can do that over your normal Shellac.

As I said, I would shy away. I wouldn't rule it out but would not suggest.

I used shellac on my bathroom trim and doors. After about 3 years some of the trim and doors showed some deterioration of the finish, especially in my daughter's bathroom. She takes looooooooong showers, and the ventilation is poor. Thus, there is a lot of condensation on the upper portions of the doors and trim, and that's where the deterioration was worst.

However, the fix was quite easy. I just scuff-sanded the shellac and slapped on another coat, and now it looks great! There may be other finishes more durable, but not easier to apply, and removal is a breeze, too.

Doesn't sound to me like you'd have a problem, especially if you used freshly made dewaxed shellac. But even if you do you can, as another respondent said, just wipe on another coat.

Polyurethane. Holds up better to moisture, plus alcohol won't hurt it.

Or a precatalyzed lacquer.
