12" carrera marble flooring
My floor build up is strange. 12' span and 16" on center. I will start from the bottom. Actual dimensions. 2" by 7 1/2" doug fir joist, 3/4" tongue and groove doug fir run perpendicular, another 2" by 7 1/2" doug fir joist , 3/4" by 5 1/4" doug fir square edge planks run per pendicular. I then added 3/4" cdx plywood with glue and nails and topped that off with 1/4" Hardi board set into modified thinset. Now is this ready to install 12" square by 3/8" carrera marble?
