Good pricing on marine grade 3/4" plywood??

[Moe Szyslak]

Working to replace the decking on a 24' pontoon. Searching local places i am finding that $70 is kind of the 4'x8' 3/4" standard and also the least expensive.

Anyone know of a lower priced local supplier? Twin Cities.

I search for used on the list of C without any luck...

Thanks!

Last sheet I bought was $90, five years ago, sounds like you found a good price. You might want to ask how many ply it is, mine was 11 ply and had a 99 yr warranty, picked it up a Hallberg Marine.

the last sheet I bought was 2 years ago: best priced from a big Blue and grey national retail store in Rogers....and that was 5/8 and it was $60.

Marine grade ply is very expensive but not neccessary for your application. Treated plywod would suffice and should be half the price of marine grade. If you want marine grade you should expect to pay the prices shown on this thread.

Depending on what grade marine ply you want that? $70 for a low grade should be decent for a pontoon floor.I like the post saying use treated.

Siwecks lumber NE Mpls.

I can remember the exact cost of the plywood, it was a few years ago but it was half of what was quoted.

Good Luck,

Mike

If the wood is going to come in contact with aluminum, you do not want to use treated plywood as the chemicals in the wood will corrode the metal.

Also got mine (marine ply) in North Mpls a couple of years ago- they had a couple of grades & priced accordingly. I used the recommended grade & it was the lower priced. $ 70.00

Looked into 3/4 treated but everyplace I checked the sheets were warped or the edges were slightly curled. I was afraid the joints would be very noticable after the carpet was installed.

I have seen where some of the guys building fish houses (on these forums)are using a wood product called "Advantech" for their floors. You might want to check that out.

It can be a big job & you will only want to do it one time.

Good Luck

I just bought 6 sheets of marine grade 1/2" from menards for $50 per.

Why do you want 3/4" on the pontoon...Seems excessive.

If the wood is going to come in contact with aluminum, you do not want to use treated plywood as the chemicals in the wood will corrode the metal.

Agreed....but you can still use it. I was going through a similar experience some years ago and after contacting several repair shops they all said to use treated plywood. Just make sure you seal it with something (paint) before it rests on aluminum. However, if weight is an issue, then marine grade must be used.

Look around for 3/4" CCA treated marine plywood (manufacturers use 7 ply), it is the plywood used by pontoon manufacturers. It is the old wood treatment and will not interact with the aluminum. Also make sure to use a joint seal tape at all the joints (which should correspond with a crossmember).

Is the pontoon 8 or 8-1/2 feet wide?

[GotALunker]

agreed...do NOT use standard treated if it will contact alumninum. Do yourself a favor and just get the marine grade...
