Epoxy / Delam question

[wilcox510]

I have some skis with tail delams, so I epoxied them. However, apparently my epoxy has gone bad or I mixed it up poorly because after 36 hours it is still gummy, even the stuff I mixed up on cardboard. So I am assuming its going to fail. When it does, how do I get all the bad epoxy out of there without worsening the delam? Do I just scrape out as much as I can with a pick and call it good?

anyone???

Your probably better off doing the repair now especially If the epoxy on the cardboard is still soft. The good part is the epoxy inside the delam maybe even softer(easier to clean up). Unfortunately you may delam it a bit further when cleaning it up properly(to get a good bond it is very important to remove all of the fucked up existing epoxy). I'd personally heat up the affected area with a heat gun to further soften the partially set epoxy pry the delam open and start scarping it out with a razor-blade/utility knife once you've removed the bulk of the epoxy then use strong solvent like acetone to clean up the two surfaces prior to re-epoxying the delam. Be sure to get some new epoxy and take the time to mix it carefully. Hope this helps.

Between which layers are the delam?

What kind of resin did you use?

Its the base that delammed. The epoxy was just some Ace Hardware long cure stuff (maybe that wasnt a good idea?). Is this acetone idea safe? Any particular brand or type of epoxy people reccommend?

In case you're doing this work outside or in the garage --

when you finish your epoxy repair, and have it all cleanly clamped together, bring it inside for a day so that the epoxy can cure in warm temperature.
