Securing OSB sub-floor to concrete

7293 Views 5 Replies 5 Participants Last post by  pinwheel45
I'm planning on putting down 1/2" OSB sub-floor directly on my concrete basement floor. My question is how to secure it? I have been told to simply use masonry nails with a baby-sledge, but have read a lot about using tapcon screws...

Can I use the masonry nails and be secure or should I go another route?

Thanks for the replies.

I've painted Drylock (2 coats) on the concrete floor, and was told to put a 6 mil poly vapor barrier down and then the OSB. on top of the OSB i planned to put Bamboo planks due to their resistance to moisture, but I need something to secure them to and was told to put down OSB....other thoughts?
