Cure Before Surfing in the water?

General Discussion

Hello, I’m new at glassing and had a question.

 

While using polyurethane on a PU blank is it necassary to wait a certain amount of time after sanding the hotcoat to take the board out for a maiden voyage?

Like a day, week, month or as soon as its waxed…

thanks

Polyester on Polyurethane…I always wait 1-2 weeks, but that’s just my garage hack experience. I figure if I’m gonna spend the money to build a board I can make sure it’s well cured before surfing it.

Hopefully one of the pro glassers will chime in.

I use uv poly and don’t wait. I figure the lam has had plenty of time to cure, and strength is in the glass. I don’t know how true it is, but i heard uv cures much faster than resin cured solely by MEKP. true?

I have always been told wait 24 hours for poly resin before sanding.

all things considered…

you can wait for months

and it gets harder and harder

I have boards that are

going on twenty years unridden.

but , the real cure is in the water.

if you take em out green uncured

be very gentle and caress the board

 by wrapping arms around

through push throughs an’ dont squeeze

 the rails with plummers pipe wrench grip

dont duck dive with a knee klubbing the deck

or heel weighting slamming cut backs.

abusive use parameters derive damage

more than measurable performance.

making a board last is an old mans

game,prepare for old age

with a few good boards that

arn’t a’wreck.

Took this board out of an old 80’s piece of trash. It’s small (like 4’6’’ small) but i’m sure it will fly. 3fin bonza set up, I hand foiled the wooden fins and glassed em’ proper w/ a nice resin bead. Had to cover up some brown so gave her a groovy fabric inlay, “magic carpet”. Can’t wait to take it out on a fun spring day. Thanks for the intrest.
