im installing hardwood floor.over slab.what do i use to fasten plywood to slab and how many per sheet?
Answers:
Your main concern should be a moisture barrier. Ground moisture will come up through concrete, That will rot the plywood as well as the flooring.
Other answers:
there is a concrete screw that you can use, or you can use hilti nails (name brand of a gunpwder fired nail that is designed to go into concrete). in regards to number per sheet i would consult the building code.

Not sure, I do know it's recommended to put down a vapor barrier (such as Drylok) before you put hardwood over concrete, especially if the floor is below ground level. This will help prevent the hardwood from warping should the concrete floor "sweat."
