So I use epoxy resin and sugar. Is that right? Doesn't it dissolve? Don't ants eat it? How do i know when i have put enough on?

Ta!

No normal epoxy will brown with exposure to UV.

Don't agree, if resin can find it's way in, so will salt water, that board would way a ton!!!

Polyester (surfboard grade, nice and clear) is harder, so last's longer.

That's what I use, if it hasn't gone off (don't use it very often, and it doesn't last long in plastic containers).

It's worth getting Sam's run down, cause resin thickness is critical, too much and it really soaks up the sugar, ends up thick and heavy.
Too little and the sugar doesn't stick very well.

The top layer of sugar will dissolve off, but leave a layer behind that the resin has soaked into and bonded with.

It's not too hard, tape out where you don't want it, brush or pour resin on, even it out to desired thickness, sprinkle on sugar until there's no sign of wetness, the sugar can look a bit damp, but it's best if it's all dry, just to be safe.
When completly hard brush off excess sugar then if you have ant problems a good wash to dissolve the top layer of sugar.

The trick is resin thickness, I think 150 mls/grams should do a waveboard.
My last board, I thought I had it exactly right, just one layer of crystals tightly and evenly spaced, but it's too even, is a bit slippery.
Think now it's best if there are 2 or 3 crystal layers, then it tends to "clump" a bit causing small iregularities that increase grip.

A mate of mine tells by the feel of the brush, if it drags a lot, the resin is too thin, if it doesn't drag at all the resin is too thick.

Best thing to do is experiment on a small surface till you get the knack.

Thanks Decrepit/Sam

I will experiment....

1 wave board = 40mls UV resistant epoxy + 200ml caster sugar

You're doing them a lot more often then me juice, but 40mls seems like an awfully small amount, a decent size brush will just about soak up that much. Are you spraying it on??? And how much of the board are you doing? I only go just far enough in front of the mast to cover the tacking area. (In case I ever learn to do them) And still use more than 100mls I'm sure

Wow, I'm impressed, so what about the sugar? how close are the grains?
As I said earlier on the last board I achieved a thin tightly packed surface that's a bit slippery. Think it would be better either thicker, or with less dense grains. If they were a bit further apart, they'd probably grip better.
