I have an epoxy fillet that is still sticky after a few days, it is hard but is sticky on top. Is this due to an improper mix of epoxy? Is there anything I can do to fix it?
I had the same thing happen. I was told that it would dry eventually but after 2 weeks it was still tacky.
What I did was mix up a small batch of epoxy with just a little extra hardener and applied a thin layer.
Worked out great.
