can treated plywood be safely used for boat decking
Proper Plywood Decking Materials. Plywood decking is a great choice as an alternative to regular boards as long as the right plywood is used. Normal plywood is only four or five layers of wood and is bonded together by a basic epoxy. The only kind of plywood you should use as decking material is marine plywood.
Location: Caledonia - Spring Lake DO NOT USE MARINE GRADE TREATED WOOD OR TREATED PLYWOOD!!! It will eat the aluminum over time like rust does to metal.
The simple answer is pressure-treated lumber can be used in any interior application except cutting boards and countertops. Some have also asked, after they’ve found pressure-treated lumber installed inside their homes, if there is any danger in having it indoors. The answer is no. There is no danger of either leaching or off-gassing.
Re: Treated plywood deck and alum boats-Don't do it! I don't mean to hijack this thread, just wanted to make everyone aware that there's a product available called Nautolex that is all vinyl and can be used instead of marine carpeting.
Dale Miller 1st off marine plywood is not treated, it has more ply layers with no voids glued with with moisture proof/resistant glue, left unsealed no better then exterior plywood.
Read up on it and found that its better to use plain ext ply and seal it with a good oil stain. Its been on five years and still in good shape, except the carpet will come loose if you spill gas on it! The real deal on marine plywood is simple. Marine plywood is not treated with anything to prevent rot.
When I redid the deck on my boat I just used regular plywood. The place that I looked it up on line said not to use Marine plywood because the fiberglass rosin does not stick to treated wood as well as non treated wood. So I put the resin top and bottom and it seemed to work well. That was about 5 years ago.
Transom and sub-deck pressure treated remains in perfect condition. I've cleaned the thing out, ready to do it better this time. Anyway - my initial idea was cut back on some weight, use 1/2 plywood this time, encapsulate with thin cloth and 2 part epoxy..
Marine ply is going to be the cheapest but not necessarily the best. For a bit more you could go with Divinycell foam which will not absorb water and rot like unsealed marine ply. I re-cored the deck of my 25ft sailboat with marine ply and had to seal the sheets with epoxy.
Ground contact and horizontal installations -- Pressure-treated plywood is rated for ground contact, and it will last longest in a poor drainage situation, such as the surface of a deck or walkway. Total immersion -- When building a cistern or other outdoor vessel to hold water, use marine-grade plywood.
