There is a wooden (pitch-pine) ceiling in one room in my Victorian house which was very badly stripped with a hot air stripper which burned the wood slightly. Then the ceiling was varnished (with polyurethane), presumably to hide the burn marks, but it didn't do this very well.
I'd like to strip the ceiling again, and I'm wondering if the best way is with a light sander, or with a Skarsten (or similar) scraper? Or maybe some other way?
