Greetings –
I am about to start a project NYC in an apartment building that was built in 1974. The building is reinforced concrete. The floor is a 4″ thick concrete slab. The project calls for us to remove the original glue down parquet flooring and install new 3″ x 5/8″ x lenghts that vary from 3′ to 5′ prefinished bamboo flooring. What is the minimum thicknes plywood underlayment that we should use and what is the best way to fasten the plywood to the slab? Any problems shooting the plywood to the deck?
Thanks for your help.

If the concrete floor is decent flat, why not float it?
Otherwise, I would think you would need at least 3/4 ply glued and shot to the concrete to accommodate an even shorter than 2'' staple.

Hi Calvin thanks for the response. I haven't stripped the existing floor yet so I don't know how good ( flat ) the slab is. When you say float is that with adhesive or without and will the existing adhesive pose a problem? With a floating floor are there problems with voids where you get that hollow sound? I figured plywood underlayment would be cheaper than grinding off the old adhesive and then floating the floor with a self leveling concrete underlayment.

You'll have to make the decision on the conditions you run into as far as doing it floating. I've done both. I would say that the bamboo sounds less hollow than a similar laminate floor. However, you still need the flatness that you have to have for a laminate floor. I'm not sure about glue down, tho a guy here named Cloud Hidden has glued down in his home I believe.A great place for Information, Comraderie, and a sucker punch.
