Hello,
I am planning to lay hardwood flooring on the second level of my condo. The material is all tongue and groove. I thought the subfloor was all fiberboard... I thought wrong. I just discovered sheetrock! Is this really sheetrock? Can I glue to this sheetrock? Do I have to remove all this sheetrock and lay down fiberboard in order to lay hardwood? Why is this sheetrock used? I figured it to be a sound barrier. Please help!!
Thank You!
