Marine Ply

[Parm]

Hive mind of the forum, where can I get a pice of marine ply 400 mm square and 18mm thick without having to buy a whole sheet ?

Cheers Parm

Last bit of marine ply I needed I went to a boating place. If there’s one near you, ask, I’m sure they would know where to go. I haven’t wanted any for a long time & the one I used is long closed.

Does it need to be marine ply?
Facebook marketplace is where I can get good quality birch ply for about £2 for that size

 

[Beanwood]

You’re welcome to a piece but postage might kill the idea

It’s for an outdoor application, tried birch ply, only lasted a year before it started delaminating

B&Q have a piece on their site that is 610mm square 18mm marine, only availble online though and not cheap...cheaper than an 8x4' sheet by all means, but 40 quid all the same

18mm Marine Plywood 610mm x 610mm (2ft x 2ft)

Marine plywood is typically used in applications where the plywood will be exposed to moisture or high humidity, such as boat building or construction projects near bodies of water. The 18mm thickness of this plywood is ideal for applications that require a strong and durable material.

What about an off cut of buffalo board? Not that I have any...

How soon is it required, I may have something suitable
What is it needed for as other materials may be more suitable

Buffalo board would do. I've got an off cut somewhere @Parm that's sat outside for quite a while. Just seal the edges and it lasts for ages.

Postage would likely kill it from here and rather ironically I had someone drive down from MK to me and back yesterday

I can guarantee you that wont be "real" marine plywood at that price, its shuttering plywood with a finished face both sides. Last time i bought marine plywood for a high end roofing job it was £135 a sheet and that was discounted. I hate with a passion how the word Marine is thrown about relating to plywood. I buy 2 pallets a month on average which is about 90 sheets and the difference in quality from month to month is mind blowing and usually from the same manufacturer.

Wow, I’m out of touch. The last full sheets of marine ply I bought were probably £35 each!

Hmmm.....my flat roof was done by the FiL in 1987. 18mm marine ply. Genuine stuff back in the day. 3 layers of felt badly done thereafter. If it had been any other ply or OSB the roof would have come in by now.

Was in Selco earlier, saw 18mm marine ply

https://www.selcobw.com/marine-plywood-1220-x-2440-x-18mm for £95.99 Inc VAT. The small print though.....

"Marine plywood is a high quality product suitable for use in both humid and wet conditions when suitably sealed".

Bet it's not a patch on the old stuff.

I did get some a few years ago from Travis Perkins, specially ordered in. Like the stuff I remember. Heavy with the individual plys really dense / close grained. When I did the surround for my part sunken bath.

You would probably might get just enough for a model boat for £35

Does it have to be plywood parm?
I can probably cut you 3 400mm squares out of some of the broken pig feeders at work, they are 6mm so you’d need three but polypropylene plastic which is virtually indestructable.

Phenolic faced is hardy enough but the edges need maintenance. The timber supplier near my place in England sells phenolic faced as offcuts, I assume people come in for cut pieces for their trailers and pay the higher rate for the convenience of cut to size and a steep added premium per M2 for not taking full boards.

TBF it's heavy on the saw blades if they're cutting it up cut to size.

I don’t know what that is ?

It’s got a table top

 

[Parm]

Situation update, I’ve now found some ally checker plate, quite fine, it will do the job nicely, the design consultant has decided.

Marine ply no longer required

Phenolic resin impregnated plywood.
