Hi

Just joined as I have a question about weatherproofing a 10mm ply deck board for my aluminium scaffold tower.  The phenolic resin impregmated original ones have delaminates and expanded, pulling the fixing screws through.

I have a piece of 10mm ply  but  want to make the standing surface more durable and weather proof, though it will be stored inside.

I was thinking epoxy would be hardest but wondering whether to add a  layer of reinforcing also?

Any suggestions for  a suitable product?
