How to Redo Laminate Countertops. Laminate countertops are wood base (usually particleboard) topped with a hard thin sheet of plastic. Re-laminating a countertop doesn't require the removal of the old laminate, as long as it's still adhering fully to the frame. By buffing out the old laminate, you can set the new laminate sheets in place directly over it. The laminate is attached with contact cement, which is a form of glue that is applied to both surfaces and allowed to set before touching and bonding.
