mark poulson Posted January 30, 2019 Report Share Posted January 30, 2019 See if whichever epoxy you use has a contact number, call/contact them, and get the information straight from the horse's mouth. Years ago, I called Etex, and spoke to one of their techs. She answered all of my questions, and I never had any issues with Etex from that point on. 1 Quote Link to comment Share on other sites More sharing options...
