Is MDO plywood suitable for skate ramps in an outdoor setting?

Question

I have built a mini ramp in the back yard and tried masonite. It was a failure. The tarp blew off and the rain trashed it. I'm looking for a material with a smooth surface that doesn't nessecarily need to be covered. A guess is MDO but I'm not sure. Skatelite is definately out of the question.

Answer 1

No. MDO will fail if it is wet.

Answer 2

no, MDO will fall apart when it gets wet.

Best I can do is pressure treated plywood, but it's not too smooth. Take a walk around a Home Depot, there may be some plastic sheets that you can lay over the pressure treated plywood.

Answer 3

MDO will not be durable in wet weather even if you use marine plywood, best is use ordinary plywood and cover it with plastic sheets
