Q: I was hoping you could give me some advice. I rent an apartment which has nice hard wood floors. I have been here for 2 years now and have noticed the shellac (I think it is) is peeling off in spots. It is becoming worse and more noticeable. How can I fix this and prevent more shellac coming off? I want to take care of it before it gets worse.
A: If your finish is shellac it will dissolve if alcohol is applied. More than likely somebody has applied a coat of finish (polyurethane) over an existing coat without proper preparation to gain adhesion. The real solution is to remove at least that top coat of finish by screening with a polisher and abrasive screen, or more realistically to have the floor completely re-sanded and finished.by
