Hello
I was sailing normally and when I got out of the water I noticed that a bit of material was missing from my board.
How am I supposed to fix this? Do I have to try to remove everything so that only the black part is exposed and put a fiberglass blanket back on? Or can I take it all off and let the black part show?
Thanks!!
Should investigate first why that happened and make sure there is no water entry into the hull.. It seems that the bottom might have been delaminated and was repaired with putty ?
Suspiciously looks like a previous repair gone. DIY repairable with a lot of material and time, but I'm not so sure will last to long.
That looks really bad, I would find someone who repairs boards for a living and see what the say before doing anything.
And to answer your question, you should not remove the rest, a layer of fiberglass peeled off, and that gave the board strength, with it missing you could have a major failure out on the water.
So i'm assuming this is a secondhand board?
And the previous owner did a 'repair' on it, which has delaminated.
If a big section has come off like that then the rest of the repair is likely to fail as well.
I would be asking the previous owner why it was repaired and how far the repair goes.
All the loose stuff needs to be removed before a proper repair can be done.
What happens then depends on what info you can get from the previous owner.
I agree. Can see by the cloth and colour of the resin that somebody has fixed it and repair has delaminated. Its going to be a good one to learn repairs on if you're handy. Just needs all that perimeter sanded back (machine sanding preferred) to get a nice wide bevel, only sanding the carbon verrryy lightly, and give it 1 x 4oz all over the exposed area, fair, sand, don't even paint.
Hello everyone.
I need to post new photos because is going and going straight to the fin box. it is a high way :D
the black layer, i think is carbon is good for now.
but. if i "do" a knock knock near to the fin box it sounds like it will explode :D
maybe i need to sand all the board, make sure theres no water (but i have water inside, but it cames from the up body, dont worry ;D )
ok ok :D
1? sand all the board
2? fill all the holes with epoxy and microballons
3? epoxy and cover all the bottom with fiber cloth??
4? sand it, but not like a mirror ? :D
the easy solution is "let it go. i shall see, said a blind man" :D
Can the board break in two parts??
Many thanks!!
a lot of surfboard repairers repair the epoxy in epoxy but because its cheaper and quicker do the hotcoats/filler coats in polyester, this looks like one of those repairs - have seen this before and had to re repair other peoples work because they cut corners. as others have said sand back and re repair

That's one for the bin
No such thing. I want it.
Hello again!
Someone can tell me what is the material sequence?
from top to the bottom
Fiber glass
Carbon
PVC
fiber glass
EPS (core)
fiber glass
PVC
carbon
Fiber glass
is this correct??
Thanks!
^^^ probably....
I thought you were not going that far? This only needs on or maybe two layers of 4oz glass

That sounds right, but every manufacturer is different, contact the manufacturer of you board with model number and serial number and then should be able to tell you.

Not necessarily ... and why do you care? You are just fixing a outer skin problem, and you will certainly never have to go across the whole hull! Sand well, but not so much to get into the hard foam, apply, as people who know much more than I do have already said, one or two layers of 4oz S-glass and you are done. Better than new (sort of).
Hello!
Thanks for all answers.
Why i'm asking the sequence? Just to know if the "layer" black is carbon or painted fiber glass,
if the black is carbon, ok, i can sand it without much care because i have two more layer till the "core"
thanks :)

No No!!! The carbon is the tensile strength of the board, what's under that is mainly for compression. You need to maintain that tensile strength! As Mark has said, go very lightly over it, all you need to do is rough it up a little so you get a good bond with your next layer.
If it is carbon of course, I've seen plenty of boards where it's just fibreglass with black resin.
^^^ exactl;y
As we said at the very start this looks like a bad repair that has fallen off. I cna tell by the yellow resin and the laminate is too thick at one edge.
The black stuff is good unless its soft underneath or feels delaminated. There will be just foam under that so don't sand it.
Id say it is biaxial carbon, can see the diagonal threads of the binding filament
All it needs is the loose edge on the very outer layer to be sanded back a bit to a bevel, then a layer or two of glass.
mate pays to listen to what decrep and mark have to say
both noted board repairers and builders.
On the middle i will do two layers, on sides only one.
i will do vacuum with peel ply and "felpro", i dont know how to say in english, i know i didnt need to do vacuum, but with this way the epoxy dont go to the floor.
thanks everybody!! Tomorrow will be the day! :D
