Cut one piece of melamine the same size as the finished countertop. The box is 2 wider than the sink mold on all sides and sloped in the front to follow the slope of the sink mold. On the table saw rip four strips of melamine 2 1 4 wide and long. The concrete forms are made of 3 4 melamine boards.

Clean the entire form with denatured alcohol to get rid of any excess silicone and debris.

Then add a thorough coat of a release agent spray to help prevent the concrete from sticking to the edge liner and sink knockouts.
