I have a 40ft wide by 37ft high wall to install Hardy. Is there any way of installing sections vertical... (half way) then move over and do the other parts... as my walking board is only 20ft. Wide and can't do a full 40 feet stretch at a time. I'm thinking blind nailing is a no go. But perhaps bottom nailing will do if I attend to it like laing bricks.. staggering. Possible? Any suggestions for a one man crew, Thanks!!
