Epoxy is epoxy is epoxy.............
Right or wrong?
Any reason why this stuff wouldn't work on a ply boat project?

It's solvent based - resins used for coating ply etc are usually solventless as they do a much better job of keeping moisture out.

Specs require below 6% moisture content. You will only acheive that with plywood directly from dry storage, when the typical moisture content is likely to be around 8%.
Depends on the ply boat you are building. Probably no problem for a Mirror dinghy or suchlike, but if you are considering a major construction for offshore use, then you need to check further whether it is specified for wodd use as well as concrete/masonry.
Epoxy is epoxy is epoxy....? Maybe. And maybe this stuff is pure epoxy. But equally likely is that it is an epoxy based substance with additives to improve peformance specifically in concrete and masonry, and only the manufacturers will know whether or how this affects its use on timber. It may be fine, or it may be useless!

I've emailed the manufacturers, will post any reply.
Thanks all.

''Epoxy is epoxy is epoxy.............'' Right, but also very wrong!
'Epoxy' is a class of chemicals with one feature on common, but widely diverse in other respects, and resulting very different properties: --
-- in the same way that wood is wood is wood.....Or drink is drink is drink!
You would not make a mast or spade handle from either balsa or ebony: and you should not give a thirsty child a bottle of finest malt!
For a for something as important as a boat project, do go for the right stuff!

Yep, agree with Piota. Araldite were the first (UK) epoxy resins that I know of, and we (industrially) had at least 7 for different conditoins (heat, load, application material...). Wonderful stuff.

Epoxy is Epoxy is Epoxy .....Wrong!
For a start you can have epoxy adhesives or epoxy sealants to name only a few applications. What are you trying to do. Stick the ply together or seal it? You dont say.
If you want an adhesive - dont touch this at all. It is a coating and will not work as an adhesive.
If you want a coating then get one specifically formulated for wood. THis is a concrete protection system and will have a low viscosity (low viscosity epoxy system with a high % of solvent) aimed at full wetting of the porous concrete. It is not designed for wood.

That's the reason for asking, not one of my specialist subjects.
Too right about the single malt, Bells will do fine for babies......

Very quick and helpful reply.
Thank you for your enquiry.
Unfortunately Resbuild Floorseal is not designed for use on timber. The material is heavily solvented and is designed to penetrate cement based surfaces to dust proof and seal the surface.
We do not have any systems specifically designed for timber. Our Resbuild DPM has been used on timber in the past and may be suitable, however we could not offer any specific recommendation.
Resbuild DPM is a solvent free Epoxy normally applied as a damp proof membrane on concrete. It has good damp tolerance and slight flexibility, which may lend itself to your application.
We would recommend you trial the material to satisfy yourself of its suitability.
I'll stick to the tried and tested stuff then..... /forums/images/graemlins/wink.gif
Thanks again.
