Hi
I have the 500g Black epoxy paste. I have tried to mix it twice now with my Epoxy resin and both times after painting with it, it has black spots that remain tacky. Once everything is cured, these spots are still like black paste. I assume it's because I'm not mixing properly. Any tips to the best method. Im mixing (as I thought) thoroughly by hand with a wooden stick. In 200ml total quantities with 10% pigment.

Thanks
