Many homeowners look forward to installing a granite countertop. For the most stable installation, your cabinets should be properly prepped. While some fabricators only recommend prepping for thin counters, many recommend prepping cabinets for all countertop weights to provide a flat, level surface. If your fabricator is not doing the prep work, provide a surface that's as stable and level as possible. The result will be a longer-lasting installation with fewer problems.
Things You'll Need
- Measuring tape
- 3/4 inch plywood boards sized to the depth of the cabinets
- Shims or small, thin pieces of wood
Measure the length and depth of the cabinets with a measuring tape.
Lay the plywood boards out on the tops of the cabinets so the front edge of the plywood stops 1/2 inch from the front of the cabinets. Place a level on top of the plywood to check for low spots. Shim up the plywood with small pieces of wood placed below it on the cabinet frame until the plywood is perfectly flat and level.
Drive screws down into the plywood, attaching it directly to the cabinet frames or stiles with a drill. Sink a screw every 18 inches along the run of cabinets for best support.
Tips & Warnings
- If your counter will overhang the cabinets by more than 6 inches, place a 1/8-inch metal plate on the edge of the cabinet, extending outward to within 6 inches of the edge of the granite. This will provide the necessary support without obtrusive support brackets.
- All appliances, except for the dishwasher, must be installed and in place before the granite arrives.
