Hi
I applied some nitramors to heavily glossed skirting. The paint came off as expected but exposed a layer of some substance between the wood and the paint. This layer appears to be about 2-3 mm thick and is dark brown on the surface but when scratched shows up white underneath. Its like a thin crust over the wood and can be scrapped away. Is this shellac? From looking on the net, I can't find out whether it dries to form a thin film like what I have uncovered. Anyway, it has left the area quite patchy looking and rough. It seems the nitramors has unevenly affected this coating.
Can anyone confirm what this coating is? Is it shellac? (house was built in 1910). Also what to do with it. Is it easy to remove and how should it be done?
Cheers
Eddie
