Hardi board exterior

[drs3317]

I'm using 9mm Hardi board 4x8 sheets on the exterior of my workshop. I searched their site and cannot find how to finish the joints for exterior. Do you use the same process as interior using their putty and paper tape?

I believe your choices for the vertical seam are battens or caulk. Horizontal seams need z flashing.

Google "Hardiepanel installation".

I used caulk on my shed. It shouldn't be much since they overlap.

These are 4x8 sheets, not the lap siding. Thanks

OP is going to want to use the ones for southern climate. (Assuming they're different)

Using a reglet on the joint is also an option:

I was going to say reglet or (and they make a reglet for it) reverse batten - take strips of galvanized steel and then leave a reveal. We did it on a garage with cedar on the side that faced the house and then ripped 12" strips for the other sides. the reveal was 1 1/2"
