I am putting in cabinets on either side of an existing fire place. Raising the cabinets 1’ off the floor. I want to use stone veneer on the front of the raised base for the cabinets. The front measures 1’H X 5’W, 5 square feet in total. My question is, do I need vapour barrier and metal lath over the plywood? Or can I use an adhesive like SRW vertical instant lock adhesive placing the rock right on the plywood?
