In poor judgement, I used a steam carpet cleaner on area rug which has removed the finish from my oak wood floors under the rug in several 8" spots. Is it possible to refinish just the damaged areas, or the whole 5x7' area without having to refinish the entire floor? Floor is utherane coated oak 8 years old in fair shape (prev homeowner had 3 kids and 3 dogs). I'd like to avoid having to have the entire floor prof refinished as is a huge area (approx 1500 sq ft). Any suggestions would be greatly appreciated.
