Q: I have just salvaged nearly 800 square feet of red oak flooring. Many pieces have had their tongue or groove cut off where the planking has met the wall. Still other pieces were installed butted end to end with the tongue or groove removed (they were probably salvaged and reinstalled years ago). All in all, the floors seemed to hold up well and really did not look too bad. My question is this, should the ends be run through a router to restore the tongues or grooves before installing?
A: Personally, I think I would just make sure I nailed within 3″ of the end and glue the ends with a polyurethane adhesive. It is much less time consuming and you will still achieve a strong end joint.
