After a few successful boards made, I started a beautiful 6’0" bonzer. Fast forward 7ish years and multiple kids later and i finally want to finish it. The problem is, i did the lam coat on the bottom and just never finished it. The deck is still still exposed foam, it’s been through 3 moves, stored in 3 dirty sheds and multiple New Jersey winters.
The foam is surprisingly in good condition but there’s absolutely no tack on the laminated bottom.
Is there any salvaging this? Can i sand it really well, clean it up with acetone and hot coat right over a 7 year old lam? Or am i going to have to strip it down to the foam and start from scratch?
I’m no pro glasser.
My approach would be to vacuum old lammed glass with new brush attachment first.
Next wipe down with Windex.
Rinse with water. Then wipe down with distilled water.
“Lightly” hand sand with 150 grit. Then vacuum with brush attachment again.
That might do it.
But I have an experimental lam technique that I have been planning to try.
Purely Experimental:
Tape off foam to keep resin free.
In this case, I would squeegee a thin coat of resin over the entire sanded surface and wait until lightly tackey — I gauge tackey with a wooden match stick.
Then roll out a piece of 1-oz (maybe 2-oz) FG cloth over the resin coated surface, smoothing flat with a new squeegee as I go. Smooth tight over rails with squeegee too.
Then lam tacked lightweight cloth and razor trim when sufficiently gelled.
But first, experiment/practice with a piece of housing insulation foam.
Just my $0.02 of experimental lam tech.
Good luck!
I know this thread is older, but I stumbled across it and although the original poster may not benefit form this advice maybe someone else will. If you laminated and got interrupted, lost your lease, had to move etc. there is an easy fix to re-tacky. When a lam sits for a long time and loses its tackiness, just brush on another coat of lam resin over the previously laminated cloth. Use a plastic squeegee and pull the excess resin off leaving a nice even tacky coat. In your case you could just apply the lam resin on the rail and the lap area on the bottom. Laminate the deck Let it set up and then hot coat the deck. Flip the board bottom up and brush/squeege a coat of lam resin on the bottom. Let it set up and hot coat. That’s how you retacky. Just recoat with lam resin.
