I am currently finishing my basement, and would like to put in a raised floor. I plan to place 2X4 PT flat and the plywood subfloor directly on top. I would like to use a stud driver to attach the 2X4's to the cement floor, but I heard that it is tough to get the nails flush.

Any suggestions?

I've found the above to be true as you mentioned. - Although you might be able to get the plywood to sit flat by beating on it.
I would suggest you use concrete screws and a construction adhesive such as Liquid Nails if you really want your floor to stay put.

The previous ansewr is right, but you did not mention if you where going to put a vapor barried down. Would sugesst a 4 mil other wise you may have mold problems.
You can also insulate by attaching a radiant barrier so that there is air space between the floor and the foil and ply wood. This will perform better tan a 6" fg batt with no moisture problems.

If by chance you are doing the walls you can use a radiant barrier either attached behind the studs or between them. Since fg or foam can allow mold to form the foil will not.
The foil will also act as vap[or barrier.

Any questions, let me know.

Thank you.
