I own a house built in the days in which they used hardwood floors throughout except in bathrooms and kitchens. My wife wants me to remove the ceramic tile and lay down new hardwood flooring. How should I treat the straight line cut between the family room and the kitchen? This cut is across the gain or an end grain cut. I will have the same problem between the dinning room and the kitchen. This cut is with the grain and will be much easier to mate.
