Got a quote from sea dek for $6,200. Paid under $300 with this stuff to cover the same area. It's thinner than sea dek, but at that price I really don't care if I have to replace it every 3 years. Still worth it and I will purchase again.
Bought this for a little Jon Boat project and placed this on a sanded & sealed plywood deck which worked out fine. I used some gorilla spray adhesive for extra security and buddy that floor is never coming back up lol. Very comfortable and does NOT heat up in the baking southern US sun.
