Step 1: Plywood Base
We marked the studs on the wall. One wall had them 16 inches apart, and the adjoining wall had them at 24 inches apart. We measured from the corner, and marked our plywood accordingly, adding in markings for the Varde hardware supports. We did this by laying the plywood down on a flat surface (garage floor) with cabinets in position, aligning the tops of the cabinets flush to the topside of the plywood. Then we traced the Varde bracket positions onto the plywood using black Sharpie.
We then mounted the plywood onto the studs, and placed the IKEA bracket screws in their place, as well.
Step 2: The Wall
The wall was then taped for caulking, priming, and painting the plywood. Due to the way the cabinets are mounted, we decided not to use the IKEA cabinet backs, which are white.
