Rain Damage While Glassing

Hey, I am new here, but yesterday I encountered an issue while glassing the hotcoat on my epoxy board. I was glassing under a big umbrella-tent, and finished the bottom layer hot coat. 15 minutes after finishing, the rain started pouring and the tent stated letting through water. It was getting on the board, so i mad a rash descision and ran into the house with the surfboard to let it dry further. The hotcoat got pretty soaked, and you can see the little dents in it from the water. approx 22 hours have passed, and although it has dried up quite a bit, the board is still slightly sticky, and the coat doesn’t feel very hard.My question is what to do now? is the board doomed? thanks 

Hey mate maybe try doing another hot coat over the top to set the bottom off. then sand all back 

Just sand it off with a rough grit paper. Re-Hot Coat, sand board as normal.

Why not leave it for a few days to see if the warm weather will finish off the chemical reaction, i had a similar incident and I warmed the drops with a hairdryer and they evapoated with no difference.
if it was raining maybe youre weather is cold so find a warm spot to help the resin kick, its a better soloution before you start sanding away at the whole surface.

Thanks guys. Im going to leave it for the next few days (supposed to be rainy) and then put another hotcoat over it. ill update when its done

You may have trouble getting the second hot coat to adhere to the first because of the wax in the hot coat resin. My suggestion is to hand block sand with 180 grit until all is flat or very close to it.

Barry’s got the right idea. Epoxy isn’t like poly resin so if it hasn’t gone off then chances are it won’t. Use a medium or hard pad and some 40-80 grit, or a 50 grit disk, depending on how comfortable you are using a sander/polisher and lay into it. If you use the disks then you can always soak them in acetone and re-use them many, many times. Good luck.

Hi O-lipa-

Well, what did you decide to do?  There is always a few ways to skin the cat in surfboard building.  Most, if not all, “pro” surfboard builders have dealt with similar issues sometime in their board building career. 

Without seeing it/feeling it it’s hard to give super accurate advice.  Like Barry advised… sand the bad stuff off and re-hotcoat.

Let us know how it went.

Best of luck-

Brad

I sanded it down as much as possible, and just now did a second hotcoat. the sanding went better then expected, although some parts were quite sticky. Ill post pics of the board when its done! hopefully it all works out.thanks a bunch for all the help guys

So howd it go dude? hope its all perfect  now huh..
