How long do you let Durham's cure before.......

Recommended Posts

Probably not the best way but I haven't had any problems with my molds and they are nearly a year old. As soon as I demold I go ahead and slap a coat of Devcon on my molds. They still contain moisture but hasn't caused any probems for me. The surface is dry so the epoxy sticks no problem. I typically make a mold, coat it, and pour in it in around an hour or hour half. As long as the mold isn't too complicated I will slap 5 minute epoxy on it with no problems. You do have to store these so they can dry the first time but no problem. Do a search and you will find many "bake" their molds in the oven. I have before but my rush method hasn't had any problems either. I have only made probably 10 molds so far so maybe I will have some in the future screw up doing it this way.

I highly recomend baking iyour molds in the oven for about 4 hours on a low heat after you pull your mold out of the container. You want to do any touch up or if a two piece mold cutting of your pour holes before you bake it. It is as hard a bone after and almost impossible to work, but it will hold the sealer better if you bake it.
