Step 1: Building Form
(We did a poured in place countertop, so part of the form stays in place and is part of the finished countertop.) To create the form, we used 3/4 inch melamine, which has a water resistant coating. Our form was built to accommodate a 2 inch thick countertop. This depth includes the 3/4 inch melamine. Total concrete thickness will be 2 inches at the front for the overhang and 1 1/4 inches from the overhang back.
