I just completed framing and am about to move onto covering my island with HardiBacker. I plan on using stone veneer on the sides, and a solid stone countertop.
In looking at many of the photos on-line, I see that a lot of people use an edging, kind of like drywall edging around all of the HardiBacker. Is this necessary if I'm going to cover with stone? I could see this if doing a stucco surface, but not sure if it's necessary for stone surfaces.
