I am putting Ownes Corning cultured stone modules onto my kitchen but I'm unsure of this one step. I've used 1/2 inch Hardie board on the kitchen and am now ready to put the lath on and then the scratch coat.
Should I put tar paper on before the lath? I have seen some use tar paper and some not use it with Hardie board.
Owens Corning modules are not individual stones but small modules that law flat and stack flat onto each other. Kind of like dry stack.
I am leaning toward no tar paper for the one reason and that is that I will not be able to see the screws in the Hardie board as I screw on the lath.
