i am in the process of screwing down hardibacker onto my existing levelled concrete floor to stabilise the levelling compound which delaminated in some areas.
question. where the boards meet there is a joint. Do I need to grout this joint at all before tiling and I think i am right in thinking the boards don't need to be primed.
