Hi all
I've never used Everdure on plywood, only ever used epoxy.
My question is whether it cures clear or if it will darken the plywood some? I'll be using Bruynzeel 3mm Gaboon because of it's light weight.

It will darken it slightly, if that's a concern you could bleach it first.
Why use everdure at all, given the thin veneers on plywood at best it can only penetrate as far as the first glue line.
As a matter of interest where are you getting Bruynzeel from? If it's from the mob in Brookvale, it's Chinese, there is only one importer of genuine Bruynzeel in Aus.

Yes I was thinking of the Brookvale mob. They used to be good but it's been a while since I got stuff off them. What are the alternatives?

If you want genuine Bruynzeel it will cost you. Contact Andrew Denman at Denman Marine in Kettering in Tasmania Ph. 03 62674660
The stuff from Brookvale, as you say used to be good, when they actually sold Bruynzeel, the stuff they sell now is NicMa (Nichols & Mason) which is a NZ mob and it's sourced in China and the ever obliging Chinese even stamp it BS 1088.
Another excellent brand is Joubert, it's a French made ply, contact Plymaster in Qld Ph.07) 32776572 Andrew Denman used to sell it before switching to Bruynzeel
Another place where I have seen very good marine ply is Trend Timbers out near Windsor Ph. 02 4577 5277 the stuff I saw was a few years ago and they told me it was French but they weren't sure if it was Joubert or not.

Does Everdure still have the biocides in it?

Ramona, the datasheet doesn't mention biocides. I'm thinking of using it because the older Moth guys reckon it's better for sealing thin ply than epoxy.
Loose, I'm still thinking of using the NicMa, as the stated sheet weight is very attractive. As I'm only needing 2 or 3 sheets, transporting from anywhere other than local pickup would be prohibitive. Also, I'm not wanting this to be a monument for the ages, just something for a bit of fun for a few seasons. I definitely take on board what your saying about the various suppliers and their products.

The old Everdure used to have biocides in it to prevent rot. I have a feeling it was removed years ago for safety reasons! It was a thin epoxy with biocides, now it's just an expensive thin epoxy. Ordinary epoxy thinned with metho will do the same job. I used to use it when building racing dinghies for sealing the inside of ply. It is handy where you have extreme bending on the ply to give some stiffness to those tortured fibres. As Loosechange mentioned it will only go in to the first glue line but those opened up fibres will become much stiffer with epoxy slopped over it. My first boat I built was a Moth in the 1960's and the inside of the ply was saturated in copper naphthenate, probably illegal to use now. I bet that boat is still around. Consider other sealants too, concrete sealant, automotive clear coat etc.

Jethrow, if buying from the Brookvale mob, ask if they still have their discount book under the counter. Discount used to be about 10% and higher if buying large quantities.

Boron or boric acid will penetrate timber especially if it is wet and it will kill the fungus that we commonly call rot
