Quick question. I just bottom laminated a longboard I have been working on. I won’t be able to top lam it until Friday afternoon. It’s about 10pm on the east coast now and I have to be in South Jersey for work tomorrow and won’t be back in Phily till very late.
Is it horrble that there will be such a lag of time between bottom and top glassing times. I sure hope not.
If so, is there anything I can do to save it becase the bottom lam came out perfecct.
The only negative thing that can happen is your deck getting dirty, so you have to be pretty sure to cover it up nicely.
Once you come back to laminate the deck, check it out and see if its clean before getting your work done. If you have little particles on your foam just grab a tape and take them off without placing your fingers in it.
i don’t like it tacky because dry cloth sticks to it and if you adjust it, the weave gets all messed up…id think that would be the case with rubbing styrene on it.

Hello Tairygreen,,,,
small details matter.....you covered location but skipped true temp....you got some great POLY comments....but failed to let the world know if you are glassing with epoxy or poly....good answers for poly...not good for epoxy........
No matter what resin system you are using.....1/2 finished surfboards invite problems....Make a plan...follow through....Lam it and hot coat it as fast as the resin will let you...or deal with problems..........later.....
So after a good sanding, I have this outcome. those are the bottom lapsunder the top lam, I sanded them down smooth beforethe top lam but they till seemto be pretty aparent. I wasthinking about laminating the top again with 4oz cloth. The top layer already has to 6oz on it. Will that make it worse? Will the hot coat help dul those laps.
Don’t know about epoxy but with poly, I sometimes baste the foam near th lap with resin…not thick at all, just enough for the foam to get wetted by the resin. Then I let cure and grind the lap. this makes the foam hard so if I accidentally knick it, it won’t gouge a big hole in the foam.
then again, I don’t know if this’ll be a good technique with epoxy, and I don’t know what kind of core you used.
Thanks a milion for the input. This is only my second glass job and lets just say the first is being used and my test subjuect for this board.
The laps on this one were terrible, I agree. At the time of those pics above, there was a 6oz layer on the bottom and two 6 oz. layers on the deck. Yesterday morning I took the orbital to the deck with some 80 grit and really sanded down those risen laps as flush as possible. Then I glassed again on the deck with a 4 oz. layer.
I think it worked out for the best. It make a world of difference. I will prob start hot coating today.
Here are a few pics of what it looks like this morning after a little sanding.
Also, astevens, I really dig your approach of hardening the foam. I’m definately going for that next time.
Ive only made a few boards so have no where near the experience of these other guys, but have probably recently had the same problems as you. My first couple of boards came out with that un-even lapline showing on the deck, really white (from oversanding the glass) and as i tried to sand it back it shaved areas off the exposed foam and left low spots on the deck, im guessing that you are having similar problems? This happened to me as i was free lapping, but then discovered cut-laping and it eliminated the problem. You can find loads of info on cut-laping on here. Your most recent pictures looks like you have sorted out those lap lines anyway. Hope this helps a bit.
