I have a wooden ceiling that was badly stripped, using a heat stripper. This left burn or heat marks on the wood, which was then varnished (with polyurethane I guess) in the hope that this would hide the marks.
I saw a 400 watt (or so) random orbital sander in Lidl today for 20euro. I'm wondering if that would be a sensible tool to "clean" the ceiling? Or would a Skarsten scraper be more appropriate?
