Hello all, I have researched this issue - been also to the boardlady site. A friend damaged the nose yesterday and is seeking some advice. The strike is small and unspectacular but then there is a hairline split about 10cm running top and bottom. We glued the split with epoxy glue to get him back on the water for the day. It seems such a pity to make an invasive repair given it is hard to see and the crack has not displaced the surface of the board. My thinking though is the blank is split and it needs to be reglued as even a minor strike In the same place could do a lot of damage. I'll send some photos when he shares them with me - interested in any preliminary thoughts if anyone else has had experience with this. The board is a Goya Bolt.
Man! I just read some old threads on board repairs - I can see why no one wants to wade in :)
If you're right and the board is split, which is probably the case if it runs from top to bottom. The fact that it's still in alignment points to a full carbon construction, it's stiffness springs it back into shape. My approach would be to use a right angle grinder with a sanding disk. Apply it at an angle so it takes out the split and about 20mm either side. The dust created should settle in the crack and show you when it's sanded out. There's a good chance the internal core foam is still intact, it's much more flexible and shouldn't crack unless there's a big deformation. Because there's no misalignment at the crack this probably isn't the case. So with any luck you should just have to replace whatever you've had to grind out. This could include the high density foam part of the sandwich. If so, you should be able to run 1 layer of cloth down the valley, then fill valley with bog. then sand back so it about a 0.5mm - 1mm below the natural surface, then another 2 or 3 layers of cloth, sand bog and paint.
Just gluing things back together isn't sufficient, you need the tensile strength of fibres on the surface to hold it together.
My slightly less invasive measure for something like that is to sand back the epoxy you added, inject Gorilla clear polyurethane, let it cure a solid week, then cover with a few layers of 4oz S-cloth.
The polyurethane will fix any core damage without creating a brittle spot like epoxy.
Thanks for the replies. I think my friend will be happier with the second option mainly as the damage is very "neat" at the moment. if the alignment of the top and bottom surfaces had been out and some more damage evident I would give it the full treatment as you describe decrepit. Thanks again to both
