Hi Fellow Members:
I live in Kansas City where we have definite freeze thaw cycles. Based on previous threads in the old BBQ Forum, I went ahead and built out of hardibacker with a porcelian tile top and exterior rated thinset.
i have purchased Cultured Stone Veneer for the front of the bbq island as well as my outdoor bar and fireplace.
I am getting different informtion from various stone contractors. Some say wire mesh, some say wire mesh over felt paper with scratch coat, and some say stick directly onto the hardibacker with Type S premixed mortar. I want longevity of course and will do the extra work if necessary but if sticking directly onto Hardibacker exterior (even though haribacker says it is not rated for exterior projects) with Type S works I would rather go that right.
Need some expert advice to put my mind at ease....thanks all. Glad to see this board alive and well
