Lowes (and Home depot) locally carry Hardi plank in 8.25" at $6.94.
The label on the shelf identifies it at HZ5 (which is what I want). It does not indicate whether or not it is primed. It does not appear to me to be primed but I am unsure.
I really dont trust the Lowes employees to know whether it is or not. So...does HZ5 come unprimed? What does the primed board look like? Does $6.94 sound right for primed 8.25" board?
