Has anyone ever adhered Hardiplank (or other fiber cement boards)? Specifically to plywood?
This is more aesthetic than anything else. Wanted to use a material that’s consistent throughout, and to hide any fasteners. The cement boards would be cut to 2′-0″ widths and applied to a stud wall sheathed in plywood. The wall is under cover (two sides of a corridor running through a parking garage in Detroit), but will not be in a conditioned space. And one end will be about 2′-0″ from an exterior exit.
Will probably contact the manufacturer, but wanted to find out if anyone here had experienced it first. Attached is an image of the ‘look’ we’re going after.

The only problem I see is that concrete is a sponge for water. Water gets into the concrete and then migrates to the plywood... where it sits. Even covered, you still get vapor accumulation.
Look up a product called " Wedi ". It is a foam board covered with a cement facing. You attach it like foam board, but can then adhear to it like cement backer board. You could glue or thin set those cement boards on. The nice thing about it is that it is by nature 100% water proof (subject to the quality of your finishing, of course).
It comes in various thickness, from 1/4" to 2", and even has a flexible panel for making curved walls.

If your hair looks funny, it's because God likes to scratch his nuts. You nut, you.
checked out the site yesterday . . . will see what the manufacturer recommends
thanks for the info :)
That's a cool looking siding. I see exposed fasteners though. I don't know if you could blind-nail Hardi and let it hang down 2'. That seems like a lot.
