Hello,

Went to pick up my 14 ft carbon board the other day and found her like this.

It looks like a delamination to me, maybe caused from heat stress? Is the damage gonna progress and make the board unusable. It happened only in the nose of the board.
How (if) can this be properly fixed.

Colas, thanks for your finding. Well, tbh im thinking of letting it as it is, since it doesn't affect its floatation. The damage occured in the nose at the top side only.
No visible signs of damage at the bottom of the board. Yet, at least.
I already ordered a new board, an SIC Atlantis, but i love this board, and i want it as a second board for me, my wife and kids.
So if i know that the damage will stay as it is i might not proceed with a potential repair, that will cost a lot of money i guess.

A local guy here who repairs boards, suggested that the board needs only sanding the affected area, only externally, to make the surface smooth, fill the gaps and respray it, without removing the carbon layer. Don't know if it will work.

But if i know the damage will progress and affect the rest of the board, then i will definitely have to hurry up.
Any advice will be appreciated.

Thanks.

If you YouTube, sunova delam there is a good "how to video", pretty straight forward fix.

Iam,
Ive seen that video. And the backyard fix as well.
They are suggesting an epoxy resin injection in the board, but if you take a look at another post by boardlady, she says epoxy resin injection is bad for this boards, so we should better use marine urethene foam.

Looks like paint separation..... not real delam?

Actually its heat shrinkage and not delamination.

Its impossible to tell from your pics - is it soft?
Is there a layer that can move up and down (separated from core) ?
How thick is the layer if so?

Any injection of product can be problematic....foam or resin. There are a number of different problems and a different fix for each.

Mark, the carbon layer doesn't seem to be separated from the foam. Only at one point seems to be able to be pushed down and return back.
But the surface of the board seems to be uneven.

I now know that injection is not a good idea. Not good at all.

If very little softness or movement it looks like extreme heat
Only ever seen it a couple times with boards in bags and the nose is close to windscreen = 80degC ish

Is that a possibility?

Board has always been stored in a bag in a covered shelter. Away from the sun. Only time was being exposed in the sun was when i was at the beach. Either in the water or outside.

So, lets say it is caused by heat exposure, will this damage progress, or it will stay where it is now, which is only cosmetic for the time being at least.

The bottom of the Sup has not been affected, yet.

When I have repaired extreme heat damage - only twice mind you - it was probably unnecessary as it was solid. The foam melts, epoxy soften, and all returns to normal after it cools. So its moved, but set again. So if yours is pretty solid when u press on it I reckon you're good.

Basing this opinion also on how it doesn't look like normal delam (too undulating/random) or paint damage from osmosis (you'd feel paper thin bubbles that move easily and you're reporting no movement over most of it.

Thus I say no repair

Keep an eye on the bit that does feel soft, if it spreads then you'll need to grind back and relaminate that section

Hey Mark,

Thanks for your advice. That's what im going to do now.
Thanks for your time mate.
