Board Repair - Top Coat Delaminating

[modifiede30]

The top coat on my old Nitro 157 is delaminating near the binding. When I removed the binding to check for board cracks, the lamination just fell off all the way to the wood core, but no cracks were found. Seeing similar signs at the rear binding point. Can the top coat just be epoxy'd to seal out water and to level off the topcoat so the binding sits flat? Any other suggestions? I have another board, but its a bit longer and I like having 2 lengths available so retiring it is not the preferred option.

How old is the board? Warranty?

[modifiede30]

Probably 7 years or so.

If D vouches for his refinishing skills, he knows what he's doing.
Personally, I'd hang it on a wall and get something else.

Not all that concerned with its appearance so I doubt I'd go the route of a refinishing job. I just want to put something on it to seal out the elements that will allow for a proper binding mount.

Sounds dangerous to me. I'm sure water as soaked into the core thus compromising it. It's a 7 year old de-laminated board. Put it in the dumpster. It’s dead. There are plenty of good boards for sale here cheap and all of them are better then a 7 year old de-lamed Nitro! Time to kiss the old flame goodbye my friend.

Probably right. Although now that I have the lamination cleaned off around the bad part its actually a fiberglass core, so I doubt the water has done any damage.

please don't risk youself for a few hundred dollars. it i a setback, and replacing a board is costly, but when you get a new one and it is better, you'll never look back.

You can epoxy it back on, or just take it off and paint it with a good clear coat to seal it. Sounds getto, but it works.

It all flaked off - maybe the loctite ate it up. Now there's a big patch of unlaminated fiberglass so I'll likely just coat it in epoxy and let it harden, sand it down so that its flush with the rest of the topcoat. Not worried about appearance and you can tell the core is still very solid - no noise when flexed, bolt anchors are all very solid, bottom coat is perfect, and rails are all straight & clean.

As with repairing sailboards, it's never good to reuse the old laminations. If you are going to go the repair and reuse route, I'd suggest you have a look at Eva the Board lady at http://www.boardlady.com/. The best bet is to remove all the delammed area, and reapply fiberglass layers...probably 2-3 layers of Triax, or Biax with the fiber orientation matching the origional. Sand everything smooth, and you may have to extend the repair out past where it actually started. You'll want to plug the insert holes. There are snowboard material suppliers, check around on Grafsnowboards.com it's a grassroots home builder site and they have links for various suppliers.

Anyway, take your time and don't worry about overbuilding it...it may end up stiffer but just be sure to incorporate the camber back into the final layups so it don't end up flat.

good luck.

p.s. just assuming it is not already clear, use Epoxy, not to be coufused with a polyester resin. Poly is not good for structural repairs like on a snowboard.

I'll have to take a pic and post it. I don't believe any fiberglassing is going to be needed. This is strickly the top coating materials between the fiberglass core and the graphics on top. Looks mainly like underlying paint and the top clearcoat materials. Underneath this is clean fiberglass core material untouched by any marks or blemishes.

Ah, got it. You should be able to epoxy it and sand like you wanted. Best to bulid up a few layers instead of slapping a huge amount of it on there. To make fairing (feathering into the surrounding area) you can add some baby powder to the mix...it makes tapers easy and smells good when sanding:biggthump
