yup, use unmodified thinset with a small v notch trowel, then screw it down 5 rows of screws 8 inches apart per 3x5 board. Use fiberglass joint tape with thinset just like spackeling drywall seams. Next step is tile !
My tile project will be on hold for a little bit as I seemed to have strained my back and now have muscle spasms. This is some kind of pain!
We're also putting down hardwood flooring and replacing the carpet. We're converting our formal dining room into an office, ripping up the carpet and replacing it with hardwood (no laminate). My husband is getting that floor prepped right now.
