I recently orded/purchased an EPS board in “slate gray”. When I picked the board up it looked great indoors at the shop- I put it in a bag and took it along for my first session- when I pulled it out of the bag in the sunlight I was shocked at how purple the board is when outdoors. I realize that it is the UV inhibitors is the epoxy resin that is causing this, but I am pretty disappointed in the color - since gray is a very subtle and non-flashy color, while purple is pretty much the opposite of that. The question is: Should I just live with it and try to let it grow on me? (purple is probably the last color I would ever knowingly order) I have thought about painting the board- I can prep/spray well and make it look good, but then obviously chips, scratches are an issue as soon as I start using it with paint on it. Can the board be coated with another layer of resin (either opaque or green tint to offset the purple) without making it too heavy? Any other suggestions- thanks!
Photo attached- on left is the color that I ordered, on the right is mine in the sunlight- it looks pretty much like the one on the left when indoors.
When you ordered the board, did anyone mention anything about UV inhibitors in the epoxy causing this rather flamboyant change in appearance? That gray looks cool.
No, this was never mentioned until after the fact. The shaper has only seen the board indoors so I get the impression that they don’t really take my color complaint very seriously- I did send along a picture but the response was something equivalent to “everyone in the shop agrees that the board was gray”
Thanks, yes- I live in NC but the board was shaped and is currently stashed in CA- Yes, the shape is fantastic and I have zero complaints there…just trying to stomach the color.
Last epoxy additive for ultra Bright white boards give a purple finish dépend off light. It change tints in impredictable Colors. It’ll change with some uv exposition, i bet it will be better for you.
I have found that purple resin colours or optical brighteners tend to fade away pretty quickly after some UV exposure, perhaps a couple of weeks and I think you should see more grey and less purple. If its opticsl brighteners causing the purple look they generally loose their tint pretty rapidly. I have more exprrience with poly than epoxy but that whiter than white purple look on new boards always tends to fade away to normal White v quickly, so the chances are that it will go less purple and more grey every time its surfed…
One solution that I am considering is to:
Brush on a mixture of: (roughly - still testing on other epoxy test samples)
50% Fabric Dye (Green)
40% Acetone
10% Water
And then quickly rinse off.
I have been able to tint or stain cheap epoxy resin adhesive this way with pretty good result- my thought is that a green tint will offset the purple back toward gray…or brown at worst (which is bad, but better than purple in my opinion)
I don’t think that will work very well, as the color seems to be in the lam. A new hot coat with some color in it may mask what’s already there, but it may also turn into something ugly and the board may look less than new, depending on the owner’s skill at glass work. I wouldn’t touch it.
How does it ride? If a board works well for me, the color becomes irrelevant. And, if it doesn’t ride well, the board becomes irrelevant and I say goodbye.
purple can be eliminated without adding any noticeable color to the hotcoat. We’ve done this numerous times on carbon boards that were mistakenly lammed with brightened resins. We do a special Purple Killa resin just for this.
