This plywood does not share the same characteristics of being void free as normal "marine" plywood does, but it's still a marine plywood.

2013年10月31日 · Re: making your own marine plywood out of home depot plywood?? Marine plywood is 125.00 in my area, so I bought a 4x8 3/4 medium density overlay (mdo) for 50.00. It has far fewer voids than exterior ply, waterproof glue, and a beautiful one side finish. It is also called sign board and used by sign companies for exterior signs.

2011年3月21日 · Re: Marine plywood CCA treated 3/4 inch 7 ply with no voids marine plywood is what you want.

(IF all the penetrations are sealed) There are many types of marine plywood though. Pontoon decking is a marine plywood that's CCA treated and aluminum safe, it's not the green ACQ treated stuff from Home Depot that will eat your boat.
