Cascamite - still the best exterior adhesive?

[Burnerman]

I'm helping someone to restore an elderly sailing dinghy, and I need to stick 5mm marine ply onto 50 x 20 softwood - assisted by brass panel pins.
Is Cascamite still the glue of choice? Any comments appreciated!

I have been using lumberjacks recently for bonding wood together
there is a 30min and a 5min version.

Never heard of that one....thanks for the suggestion!

I would prefer cascamite over a PU glue to be honest

Another interesting product I've never heard of before. Thanks for that! seems I should be chatting to some boat builders, if I could find one.

I would use West Systems 2 part epoxy.
It soaks well into the grain .. immensely strong & 100% waterproof - it is what boatbuilders use.

Cheers for that, Rick - for sure it's a bit of an adhesive nightmare, this one!
I'll need around 20 minutes to work the upper deck pieces in, so I'll find out how long I've got before the stuff goes off.
Thanks again!

It is the dogs dangly bits, not cheap though, we used it to lay a teak deck on a narrowboat about 5 years ago and it's still all going strong now.
I'm not a big fan of PU glues especially in joints without any inherent strength of their own.
If you glue two pieces of wood together with PU glue and then split the joint, it will always split easily without any damage to each piece, whereas try that with PVA, cascamite, or epoxy and inevitably there will be split damage to the pieces of wood indicating a far superior bond.
With the epoxy just work in stages as you can, spend a little bit extra and get the pump tops it keeps the whole process so much cleaner
