Q: One visitor asked, "I've got some ¾ x 2 ½ inch salvaged maple flooring and I was wondering what is the best way to install it. It is from a school stage and is very dry. Some of the tongue and grooves are damaged, do I need to biscuit join these together or are they usable?"

A: You can rent a manual nailer that shoots 2" nails. I have a manual one, but it got retired for emergency only after I purchased a pneumatic version. Much easier on the arm! If the bottom part of the groove is broken off, you can save those pieces for finishing off near the walls, where you would have to face nail anyway. A bit of glue would also be a good idea for these boards. Similarly, as long as all the tongue is not missing over the entire length of the board, you should be able to use it normally.
I must tell you, however, that with reclaimed wood, the sanding is going to be a rough ride, and is best left to a professional. The floor will be very uneven after it is installed and maple is generally quite hard.
