How do you delaminate old skis?

Disassembling a pair of Nordica Gransport 10s for parts. Removing the topsheet is proving to be quite difficult.

You should be able to take a heat gun to them and heat the top sheet up and peel it back slowly. Not sure what parts you’ll be able to use though.

Thanks. Will the heat gun damage the ptex? I read that if you overheat sintered ptex it turns into regular ptex.


i’m doing it because I want to use the sintered ptex to patch holes in my current skis. It’s cheaper than buying the stuff online.

Sintered ptex doesn't really melt as the stick form does.

If you want to use a patch of it, you should know that the new stuff typically comes specially prepared/treated on one surface to bond. You might have challenge bonding what you can recover from a ski.

Would marine epoxy work as a glue? Melted ptex also sucks at sticking to my core/edges… My plan was to epoxy it on, use melted ptex to fill in any cracks/gaps, and then file it flat.


does marine epoxy absorb wax? I don’t really care how it looks and they’re not racing skis, so if I can skip the ptex alltogether I’m happy to do that

curious what you're up to here

love that you're having trouble purposely deconstructing the thing. i'm blown away at what marvels of engineering skis are, honestly

lol I’m trying to make my rock skis a bit more durable (I sharted them last weekend). I have a million old pairs of skis with no resale value that I can experiment with. Being a neanderthal, I’m here to pick y’alls brains

Heat gun worked!

And in case you were wondering why old skis are so freaking heavy… they literally epoxy the top sheet to giant metal rods!

This is interesting!
How old are these skis you're taking apart?

Marine epoxy doesn't absorb wax, but I've filled large core shots with it anyway. Doesn't make a big difference if they're rock skis.

That’s fair. But I do enjoy going fast on them so I would like the repair to be as good as possible.

How well does it hold compared to ptex? Ptex seems to last few runs at most and doesn’t adhere to my edges. Does the epoxy hold up better against rocks/abuse?

Put a Line Skis logo embedded into the topsheet and those bad boys will instantly fall apart

I skiied ~200 days on a pair of skis with a 8"x0.75" epoxy base repair and it wore down a bit on the surface but none came out.
