We were planning to refinish the hardwood that was underneath the tile in the kitchen and dining room, but we discovered that the tile had been clued directly to the hardwood which destroyed a lot of it. We agonized over whether or not to lay new hardwood down to match the hardwood in the living room and hallway (all of which was going to have to be refinished.) It's the really skinny planks that were popular in the 50's which are harder to find and more expensive. Finally decided that it was more economical and a lot less time consuming to just lay new flooring over the top of everything. It was done in a day.
Of course, then Ron decided that he just wanted to go ahead and do the two bedrooms off the hallway as well!!

So that added another day lol! Compared to the laying, sanding, staining, finishing the hardwood, which would have taken about 2 weeks!!
