I recently decorated my daughter's bedroom in our Victorian house. At the end I sanded the floor, it looked amazing, antique pine I think. I bought some varnish to finish the job, I just wanted the wood to look as natural as possible so i used clear matt varnish. As I put it on, the floor went a nasty colour of orange, I persevered as I thought it would dry with no colour. Alas this was not the case and I am left with a bright orange floor. How do I get it off? sand again ? or does that clog the machine? or do I use thinners?
