Gypcrete & Solid Hardwood/

I purchased $3,500 worth of 3/4 inch solid hardwood and found that my sub-floor was Gyp-crete. Nails would just pop right back out and i've found that they contractors did not seal it. Can I used any glue to install this wood or do I need to lay some other sub-floor on top of the Gyp-crete? Or possibly just seal the already in-place Gyp-crete?

There are adhesives available that can be used to install 3/4" plywood over Gypcrete for hardwood installation. Take into consideration increased height of floor in making transitions to other types of flooring coverings, undercutting of door jambs, locking in dishwasher, etc. 3/4" + 3/4" = 1 1/2". Solid hardwood is a nail down product. Contact the manufacturer of the flooring product for recommendations. Avoid voiding warranties.

The only wood over gypcrete, is a floating wood floor, something you cannot do with the solid flooring you purchased, and expect it to last. Gluing to gypcrete is a failure waiting to happen, no matter what flooring.
