Is this marine plywood?

[Speedoman]

Hi

Can anyone please tell me going by the picture below, if the information stamped on the plywood, indicates if this is marine plywood that I have brought?

Thank you

Marine Ply should be specified to BS1088 which yours isn't.

What you have is EN636-2S see the following link to determine what that is:-

no it is not

it's WBP ply, not marine

Can't really tell from that mate, i do know that a lot of ply is currently being shipped over from china to the like of Travis Perkings, Jewsons, Wicks etc and the stuff they are getting is shuttering ply (which is not marine ply) the stamp says structural ply for walls, floors and roofs so it could well be marine ply. Best to check it out with someone who can see it up close though

ATS just pipped me damn it!

 

[TJ Smiler]

You both just pipped me lol......... Ignore my answer then mate, these two say it's not and that's good enough for me

Thank you all for your replies!

I brought this from travis perkins

I cannot see any BS1088 stamp mark on the plywood but the invoice says marine plywood and BS1088

The size is 2440 x 1220 x 18

I paid £39.18 + vat

I phoned buildbase first and they wanted £57 + vat

I will call travis perkins tomorrow!

 

[TJ Smiler]

£39 plus VAT........... Bloody expensive mate. Is probably just shuttering ply

 

[Time's Ran Out]

Line 5&4 from the bottom says it requires treatment for external use !

 

[On one]

I recently paid £32+ vat for my 18mm WBP boards. And even that had me wincing!

The quality of ply varies massively, just like the quality of it from one supplier to the next. your £40+vat from TP could be way over priced, yet the £57+vat from buildbase could have been a bargain.

To put in to perspective you can pay anywhere from £15+ to £100+ for 18mm ply dependind on the quality

For a decent supplier who know their onions, look at Robbins - http://www.robbins.co.uk/pdf/Marine_Pricelist.pdf

what are you using it for ?

 

[Speedoman]

what are you using it for ?

Building a wooden shower tray base.

The shower tray is sitting on top of the plywood.

No great need for marine ply then, i use WPB 18mm for that which i get from a timber merchants and not a diy store, usually sets me back about 25 plus vat and is good quality. If your worried about leaks then just waterproof the floor. Personally i don't but i do prime the underside and any exposed edges of the ply. Tank the walls and the corner join between the wall base and the floor before you fit the tray, make sure the floor is flat and level and is solid, put extra noggins between your joists especially under the tray area.

I am actually doing everything you have mentioned, but I have brought marine plywood before, so I just brought it this time round also!

 

[Speedoman]

Is the strength of the 18 mm marine plywood, the same strength as the plywood I have brought?

 

[White Room]

I would say probably not as it states not to be used externally.

 

[TJ Smiler]

Not 100% sure on that but my guess would be the same as above

 

[One Day]

My supplier used to sell 100% hardwood WBP ply.
Recently it looked like it changed so I asked for a copy of the certs if available to file with my invoice.
The manager said it had changed to softwood core and hardwood outers but that is all anyone could get these days.
Admitted that it wasn't as good and wouldn't give any guarantees although it was still getting sold as the old stuff.

 

[TJ Smiler]

Sounds like the stuff i was on about from china, much lighter in colour than it used to be....... Thats why i only use a timber merchants for my stuff

How much?

 

[TJ Smiler]

You don't need marine ply for under your tray mate, your wasting your money. Without being sarcastic the tray is waterproof.

 

[Speedoman]

How much?

It should just be an exchange.

My original invoice says marine plywood.
