What to coat sheet of ply on cockpit floor with?

Assuming I have epoxied the boards (which I have this evening), do I need to use a primer, or can I just paint international interdeck or the Hempel equivalent straight on? As the board is only small it would be good to avoid buying too many tins! Cheers, Trev

Before you start painting you need to leave the epoxy for a week or so to go off completely, then scrub it down with water and a scotchbrite pad to remove any amine blush, then degrease and lightly sand to key the surface. I'd be tempted not to bother with a primer, cured epoxy is a pretty good base for polyurethane (ie interdeck).

this worked for me

and Dan .. varnish goes over the epoxy to give it UV protection or it cracks and goes milky!

Thanks both/all, I will skip the primer then, looks like I have a few days to concentrate on getting the engine sorted out then!!

Dear me, Euan... Somebody, tell me you knew I was joking...?

Varnish protects epoxy from UV, but varnish is itself vulnerable to scratching...unlike epoxy...but epoxy itself needs protection...

sometimes I wonder Dan!

I admit I may have struck a new low point in daftness when I bought those Hempel non-slip 'pearls'. I assumed they'd be neat little tetrapods or rice-like grains whose shape would introduce friction to an otherwise slippery paint surface...but look what it is...

I opened the pot and just stared at the stuff. It looks like white sand or possibly icing sugar. It was £8.95, so I may have been mugged.
