Weight A 1 Â½ inch thick countertop made of standard concrete has an approximate weight of 18.75 pounds per square foot. (Granite is approximately 18 pounds per square foot.) Standard cabinetry will typically support this weight because itâs distributed over a large area.
To determine the size of your countertop, measure the base cabinets or your existing countertop. If measuring the base cabinets, add an extra 3/4 for an overhang. Our island countertop will be 3â x 4â. The key to a great countertop is a well-built mold to pour the concrete into.emove the screws holding the mold sides to the base. Then use a hammer and the new screws to pry each side away from the concrete slab. Take your time with this step. You donât want a misstep that will cause a chip or any breakage. Get help from another person or two to flip the slab over.
