My contractor wants to install sleepers that he will use to nail down the flooring. I want to glue the flooring straight to the gypcrete. What do you think?

Gluing to Gypcrete is problematic, but can be done with the proper procedures. Is your hardwood 3/4" thick? If so, it needs to be nailed. You need to supply more info and also refer to the directions from the manufacturer. Jaz __________________ Tile 4 You LLC Troy, MI KERDI Shower Specialist ... DITRA Installs ...

Any way you could use portland based concrete instead? Or you could install a floating floor. Hardwood Flooring Orlando
