time to cure before surf?

The Fiberglass Hawaii Epoxy resin says 5 days to complete cure/ For ding repairs is that mch time really needed?

 

For dingrepair its not that important , curetime is always connected to room temperatures . You can always speed up the process by moderatly heating the repaired  area after its hardened. ( Curing) 

Be aware when sanding that not fully cured epoxies are harmful.

Dont add more hardener. Sounds probably weird, but ive  seen people do that more than once .

 

 

 

 

 

5 days at room temps.  But you can do a post cure in a day.   A cheapo way to do it is to build a little solar oven using a blue tarp and your shaping stands out in the sun; add a small desk fan to circulate the air… Make an enclosed tent and stick the board in on a couple blocks so the warned air can get to it.  You want to monitor the interior temperatures because on a warm sunny day that oven can get to 140* pretty quickly and you don’t want to let the temps get out of hand.   .  Depending on the hardener you’re using a couple hours @ 140-160*  will be sufficient.     

Go for heat but not too high  eps core expand and without vent it can be a drama…

For structural repair resin need to be cured. For small dings even it’s better, it’s not so important. I have guys that take boards with soft resin repair and come back after surf for sanding.
