Well I have just messed up on my first lamination. I managed to mix 1 1/2 quarts of laminating resin. But during the process of laminating, I only squeeged on 1/2 quart. The other 1 quart gelled in the mixing bucket.
WHAT NOW!
Can I mix a quart and go over top of it, even though the first coat has gelled?
In retrospect I new I would have a major folly at some point. And I have quickly learned to use less catalyst
OK, welcome to the club!
This already happened to all of us before.
I’d suggest to try and tear out all that first cloth layer, trying not to tear too much foam with it, then start again. Yes, you’re gonna loose some glass but the final result should look better than trying to fix the mess. That’s just my experience. But maybe some experimented glasser has a miracle solution?
Balsa is right, carefully pull the first lamination off. You will be surprised how easy it comes off if you take it slow. Then clean the foam up with sanding screen or surform. You won’t lose much foam if you take your time.
Do you self a favor and use UV cure resin for the lamination, no gelling in the bucket and more time to work.
better yet , use epoxy and you’ll have an hour or more to laminate and you’ll only need 10-15 ounces.
EVEN BETTER YET…
You know the batch sets in 20 minutes, what are you doing, picking your nose?
WORK FASTER!
Takes 3 minutes to wetout the complete flat surface, starting with a football size pour puddle in the middle, squeegeeing outward radially with 3" bites.
Now flip rail, pour resin and squeegee as you pour.
Flip rail back down, flip up to lap.
Can’t take more than 10 minutes, NOW you can pick your nose for 8 minutes!
Howzit Landlocked, If you pour more of the resin onto the board it takes longer to kick then what’s in the bucket. Only leave enough in the bucket for touching up or adding more to the rails before wrapping them. I agree you should be using UV so the time factor isn’t a problem. I used regular catalyst forever but switched a few years back because with the UV I can cure one side and start on the second within 20 minutes of finishing the first lay up. I stll work as fast as if I was using catalyst so I won’t lose my timing. Thanks for asking a question about poly since there has been so much discussion on epoxy lately that I haven’t had a reason to post any poly info.Aloha,Kokua
Thanks for the positive feedback. I actually have UV catalyst, but because of the tempature in North Carolina (50 degrees at best), I am unable to use it. But I cant wait for spring!!!
I guess i should be pouring more on the board sooner, and just work from the middle out. Anyways I am pleased to see educated people willing to lend a hand
UV catalysed resin goes off with exposure to sunlight. It will go off in 50 degree weather on a sunny day in winter. Do a test lay up a small piece of cloth on scrap foam and set it outside.
You should consider yourself lucky that the resin ‘only’ gelled in the bucket…just wait till you see it start smoking! and your panic drives you to throw it in the trash where you realize is full of paper and is made out of plastic and starts to melt the plastic trash can that creates a whole mess on the floor while still thinking about the rest of your board that’s dripping resin that you still have to lam up…whew…i’m not saying it happened to me (yeah right) but it could…
