I am installing 1/4" OSB on top of an old subfloor in my 1890 attic in order to prepare it for carpet. The subfloor is solid but a little rough with some small gaps which I am covering with the OSB.
Ring shank nails have been suggested to me as well as screws. Will the nails keep the floor from squeaking? I know the screws should secure it well, but are screws over doing it? If I use screws, what type should I use? All I see at the hardware store are drywall screws.
Thanks for the help.
