I'm about to cut my sheets of Hardibacker, and need advise on what to do...
I've framed the stand to support the Hardibacker sheets. Do I cut the Hardibacker to fit just inside my wood form which would cover the cement blocks, or do I cut the Hardibacker so that it fits inside of the cement blocks and sits only on my wood frame? Seems like I've seen it both ways. I filled every other cement block with concrete/rebar, and stuffed empty concrete bags in the other holes. If I install the Hardibacker over the cement blocks, then the hearth is just laying on the cement stand correct? I'm following directions on the Casa2g110 installation guide.
