Hi Ruth, My husband laid white oak, tongue & groove when we did a house rehab. We bought the oak from Lumber's Liquidator. Got a good price. I think we bought their "high end" oak as the lesser stuff can be full of knots, etc. We bought it pre-finished, and bought a pneumatic floor nail gun. The hardest part was starting: you have to be careful that you line the wood up correctly so that when you get across the room it is not gollywampus (is that how it is spelled?) against the opposite wall. You also have to store the wood in your house for a bit before starting so the wood can acclimate to your house temp & humidity. Good luck with your project!
