I came across some moisture resistant MDF today at the lumber yard. It was black and looked a lot like PVC. They showed me a sample where someone painted the top white and CNC’d some patterns into it. No burs, it looked really good. A 4x8’ 12mm sheet was $46 which seems like a decent deal. I was told others have laminated other colors on top and CNC’d thru it to get the 2 color thing going.
Still, moisture resistant is not waterproof but I thought someone might like to know it exists.
