Does anyone know if they sell Marine Grade Plywood at the HomeDepot/Lowes? If not, does anyone know a good substitute or a place that carries it? I would be looking for 3/4". Thanks.
...I would recommend getting the higher grade (has footballs only on the outside ply) exterior grade ply from lowes, and giving it a good coat of oil based paint on all sides, ESPECIALLY THE EDGES.
With composites, there is no need for a ply, as it can be formed into whatever shape. Plywood is make from thin plys, that were actually curved around the tree. I mean, the wood was basically unrolled, then flattened, and glued together, with the grain going the opposite way. They can't unroll a 3/4 inch piece, so they have to glue many together. Composites can be made however thick they want.pbw said:Isn't there a composite plywood out now days?
Marine ply is not pressure treated. It is regular ply, made with a better species of wood. Also, there are a lot more thinner plys. Also, all the knots, and voids have the little footballs in them. Not just the top ply, like the better grade HD ply.micropterus said:Pressure treated and marine grade plywood is corrosive to aluminum. You have to be careful that there is no direct contact between that kind of wood and bare aluminum.
