hopefully this is a right place to ask, otherwise please delete my posting. I have a question regarding repairs on epoxy boards. i was on a remote surftrip in indo and i got a big ding in my tuflite
board. I repaired it with a “Ocean and Earth Sun Cure”-Kit. The
problem is, i don’t know if the resin was polyester or epoxy as it was
not stated on the package. But i have the feeling it was Polyester.
How will this effect my board? The repaired area looks pretty good to
me, i only fear that the polyester resin will have any bad effect in the future on
the epoxy fabricated in the board?
Thank you very much in advance for your advice what to do next.
I’ve used both Pe and Epox. If you have the ding patched and you don’t see any problems then it will probably be alright.
When I’ve tested Pe on EPS foam it will eat it up REAL QUICK! The HD foam under the glass on your board (I think there is HD foam) probably protected all else under it. In the future carry some epoxy with you when you travel. I’'m sure they have sun cure eopxy now.
The ding was on the rail, very big but not very deep. I have only seen small parts of the foam. The Resin was hard after only 3 minutes. Did the PE eat up your foam faster than that time when you tested it? Am I right that once the resin is hard, there is no harm for the foam?
The exterior foam sandwich in a surftech is pvc foam, compatible with polyester or epoxy, if you were only seeing the outer brownish foam and not the inner white foam then you havn’t eaten anything up. The polyester resin might not stick so great to the outer epoxy coating but you’ll be able to watch for that issue.
Cured resin is fine, but eps and poly really don’t like each other, and poly will always win the fight. If they got to gether you would know about it in a big way. If ther’s not a massive soft spot next to the repair you were lucky.
