Wow! This one was a doozy! This home, built in 1896 in Fairhaven, WA had a huge build-up of…well…guck, from years of neglect and abuse. When we walked in, we could barely see the floors because there was at least a 1/8″ layer of wax, paint, and glue. We had to bust out the 12 grit sand paper and after a couple days of sanding the floor turned out great!
