Hello people,
Please help me!Yesterday i've laminated the deck of my new longboard.Everything have gone well.Today i 've gone to check the board out....and oh my god!The resin was hard and not sticky but the cloth was full of dry-ish spots.There were no air bubbles at all but only dry spots (many).Did anyone ever had the same problem?Any ideas to fix it?Please help me!
Sounds like you resin didn't kick fast enough and the resin drained out of the cloth and into the foam. was it cold out/ Did the lamination take longer than 15-20 mins to kick off? If so the resin probably drained.
Really no way to fix, just hotcoat and carry on with the build. Next time use right amount of catalyst for temp, and work real fast. Or use UV cat and save the hassle.
Sorry
If i sanded it down and then add another layer of cloth would it get any better?
Yes it would… but what a pain in the neck, if you have “lots” of them. But if they’re specific areas you can delineate, and you have the time, energy, and cloth, cut them out and re-laminate with patches. I’d focus on the large areas, as they will be big weak areas structurally. If they’re small areas scattered all over the place, you could try getting out your sander, and sanding the whole thing down to the weave, then laminate another layer right over the whole thing. You might get lucky and some of the dry spots will wet out, and you’ll have a little more structure over the areas that didn’t.
Most importantly… don’t do it again!
Thanks for that..i know it's gonna be a pain in the a.. to do it but it gotta be perfect!It never happened before but the temperature in the last days dropped a lot.Next time i'll surely put the room on fire!Would the uv catalyst work in cloudy weather?
