how to pound in nails on wood floor, air hammer?
We would like to restore our red oak floor in our original 50's home. However,the previous owner used a nail gun to nail down each 3" wood floor plank to the joists underneath prior to laying down carpet. It looks like the nails were roofing nails (2 1/2" with about a 1/4'') head. While most of the nails are sunk and the holes can be filled with putty, there are many nails that are at or above the surface. We've tried to manually pound in each nail below with a nail set or directly with a hammer the but have been unable to sink them any further.
Is there a tool that I could use to make this easier, eg. some sort of "punch"? I have over 100 nails to pound in.
