  Patching a Gel Coat Crack
  Posted by: dougd on Jan-14-14 5:10 PM (EST)
 

I won't be doing this until the temps warm up but am doing some planning ahead of time. I have a nice through and through crack as well as a hard chip out on the bow on a canoe I just picked up and since it's kinda rare I want to bring it back to as pristine as I can get. I have looked up online about gel coat repair, talked to a few folks but was wondering if anyone out there has done it as a DIY and can offer advice as I have never done it.

It's obvious I'll have to make the break clean by "cleaning" it out of chips and rough edges and then go from there. Just not sure of the procedure from there and how close it is to working with resin which I do have some experience with. I'm sure getting the mix and color right (white but a little faded)is a large part of the battle.

Any help would be appreciated.

for small repairs and it seems to work fairly well, but you don't get an exact color match.

If your hull is off-white I would probably be inclined to give something like this a try"

  Do some checking.

If possible, it might be important to find out what type of gel coat the manufacturer of the canoe used. Epoxy should adhere to anything, but polyester does not stick to epoxy and I'm not so sure about vinylester. Anyway, I would suggest watching some videos on the subject and maybe read a few articles. NC Kayaks has a pretty good article on how to do it on their website (nckayaks.com).

have a gel coat problem with my QCC, sent you a copy of the message I got back from QCC, hope it helps. Maybe we can both work on our boats together. Gotto get my baby down out of the basement rafters this summer, fix it and hit the water.

  Nice tutorial!

Very glad to see the safety equipment warnings.
I would add a caution to continue to wear the respirator and eye and skin protection while doing the sanding and compounding. I suggest a durable half mask respirator, silicone is more comfortable than rubber, and don't get the cheapie paper masks. Your lungs will thank you for it.
 
 
  Thanks!

for the links and the excellent write up! Doesn't look that difficult! Just waiting on the weather now! If the damn ice would just melt I could start milling out my gunwales!

Teimac, didn't get your email.

  It really isn't difficult...

...and if you mess it up, you just sand it down and add more gelcoat until you get it right. The one caution is to be careful not to sand away the gelcoat in the surrounding area.
 
 
  For dry sanding...

...I switch to a 3m respirator with dust cartridges. For wet sanding and compounding, I don't find a mask to be necessary as there is essentially zero airborne dust with these wet processes, but it certainly won't hurt.

 
 
  Respirators get in my way...

....while I'm having a cigar and sanding my boat repairs.

(I'm just kidding for all you busybody's)
