I'm using it on a very small job. How long should I let it dry before I apply the surfacer primer?
I looked at the tech sheet and it said nothing except that I can sand it after 12 hours. The company doesn't reply to emails or phone calls.The instructions do vary from product to product. Surely you can find the tech sheet for the brand you are using even if you have to call the company.

Yep. Solid advice!When in doubt, wait 24 hrs, scuff it and apply whatever you like.
Most epoxies scuff real easy with a red scuff pad after 24 hrs or more
and the red isn't to coarse if you're priming over it.
