Location: So. Illinois | Dumb question but where should I look to get some marine grade plywood to do some floor repairs in my boat. Would this be carried by the lumber supply companies or do I need to work through a marine dealer?

Location: Kildeer, IL | You can get them at must lumber yards. Hines, Owl, etc.
If you are going to put resin and fiberglass on your wood, then there is no need to get the marine plywood. Marine plywood means that there are no voids in the plywood (completely solid wood). Other plywoods might have very small chunks missing. When you put reson and fiberglass on the wood, it will prevent any water from getting into the wood. So there is no reason to pay more than double the price. I believe it is over $90 to get a 4 x 8 sheet of marine grade plywood. You can get the next step down for $30 or $40. |

Location: So. Illinois | Thanks for the reply.... I will be using resin and fiberglass for strength and waterproofing so I appreciate the thoughts on ging with a regular plywood.

Location: Illinois | Jerry;
I believe there are other things important in marine grade plywood, in addition to whether there are voids or not . Baltic plywood has no voids, as do different grades of veneer plywood. The water proof glue is what is most important in marine grade plywood.If you only coated one side of regular plywood with resin, it would most certainly delaminate from moisture attacking the other side.For wood to be sealed in resin, it must be dipped, fully coated on all sides or glassed into the floor or sides to be encapsulated and protected from moisture.
Call a manager at a quality lumber yard and get their recomendations. Owl Lumber in Villa Pk, Illinois is staffed by very knowledgeable people.

Location: Stevens Point, WI | I agree with using a good plywood and fiberglass and resin instead of the marine grade plywood, you will have a better floor. My father in-law just finished building a 7ft. dingy and he used quality plywood for the bottom of the boat and many coats of good epoxy, it looks awesome and is absolutely water tight. |
