Per the instructions, it's just one step-no need to prime. I've not had any issue with it chipping off-however, I don't apply it nearly as thick as Tim says to in his video. He says "think peanut butter" when applying-I apply mine quite a bit thinner-more like mayo when you're on a diet.
lol on the mayo on a diet thing...
i have been having a similar problem, but only with objects i am altering or distressing... i haven't even used it on paper yet, i should check to see if i am having the same problem. I also apply thin, maybe that is what i am doing wrong...
i recently used it on a clothes pin... once it dried there was chipped paint EVERYWHERE!!!
