The laminate on my galley counter is chipping away. Thought I would replace the laminate, but found out that part of the substrate is ply and the section between the sink and the ice box is MDF (particle board!). The MDF is water logged (of course!) and will need to be replaced. I'm a Carpenter and have never seen anything like this on land. I can't think of a possible explanation. Any ideas on why they would have used MDF in this area? If I replace the entire counter, I wonder if there is a synthetic product I could use other than Plywood. Something that would act as substrate and finish.
