My wife and I are in the planning stages of redoing our kitchen. She wants to reuse the existing cabinets but install a Silestone countertop instead of the exist laminate. From what I can see the existing cabinets appear to have been built in place using normal contract cabinet methods; i.e., MDF and other margin improvement materials.
My question now is, "is there enopugh weight difference between the lamnate and Silestone so that some sort of reinforcing is necessary?" I am particularly worried about a 5 foot section of counter top where the only support on one edge appears to be the face frame, and that is nailed to the base.
