I used Bote-Cote Aquacote water based paint. It's very tough and easy to use.

Apply with the blue gloss paint rollers from Bunnings.

Avoid sanding it. The paint finish is too hard.

Don't put too much paint on. It gets heavy.

I used a 1 x 500ml Epoxy Resin tin with 250ml Hardener, on a 2:1 Epoxy system by Norglass. Cost about $50 through Bias Boating. It did 3 coats both sides of my board. If you are going to use any fibreglass, the matting will absorb more, and you will need about twice as much to complete the job.

The bigger the tin the cheaper it becomes. If you are building 3 x boards in one hit then get a bigger tin.

When laminating the plywood together i used epoxy glue, But am lead to believe you could you the resin by using a filler to thicken it out, so you dont have to buy 2 x different products. But havent done this so not sure if i am correct.

I used a 6mm sheet of standard plywood (2 x layers). - Marine ply costs too much money and if you are going to epoxy coat it then it will become waterproof anyway.

Goodluck

Use: Megapoxy 132. It's a 2:1 ratio resin that has plenty of work time, it will flex with the board. It can be coloured with diffrent pigments to get the colour you want and has no solvents in it. 3lt will cover around 15m2 two coats and costs about $66.00.

I've repaired Kiteboards, Sailboards and supply the same epoxy for boat and surfboard building.

What state are you in?

If you just want a epoxy paint track down Megapoxy MC. 4lt kits cost around $88.00 and come in white, grey, blue and black. The kit will cover around 25m2 1 coat.
