Resin Research Epoxy for Surfboard Shaping & Ding Repair
Resin Research epoxy is super easy to work with if you’re new to shaping or repairing your own boards.
It’s easy to mix (either by volume or by weight), cures well, and sands well.
You can also pick up something called Additive F from Resin Research that can be added to the mix to eliminate amine blushing and peeling, make saturating your fiberglass easier, and help eliminate fish eyes and blemished during the hot coat.
Blue tint in the bottle, but cures clear.
2:1 mix ratio by volume.
Safe to work with.
VOC free with low toxicity.
Fast hardeners have a pot life of about 18-25 minutes and set within 2-3 hours at 77°F.
Slow hardeners have a pot life of about 40-50 minutes and set within about 4-6 hours at 77°F.
The pot life indicates how long the epoxy and hardener will last while mixed in your mixing bucket.
The set time indicates when you’ll be ready to flip or sand the board.
If you’re making a shortboard, a 96oz kit should be enough epoxy.
If you’re making a longboard, a 1.5 gallon kit is a good choice.
Longer longboards or sups will likely need a 3 gallon kit.
If you just need some epoxy for ding repair, a small 48oz kit will do just fine.
