Sanding epoxy?
Last sunday i got way to close to upper end of my reducer limit and ended up with massive orange peel on my 2 part epoxy primer. Gotta sand it all down to smooth before i go any further. Temps have been in the upper 80's to lower 90's since then. I tried to sand some this afternoon and i get gummy balls that plug up the sand paper yet. I think it just needs more time to finish cureing out. How long should it take before i can sand this? Thinking it might be 7-10 days, any body got any thoughts? Thanks

Re: Sanding epoxy?
What brand of epoxy? What does the tech sheet for that brand of epoxy say for cure times and sanding? Each brand of epoxy is a little different from another.

Put it in the sun for a day, that will speed it up.

Re: Sanding epoxy?
If you laid it on thick it will take longer to cure as well. The sun definitely helps cure quicker.

Re: Sanding epoxy?
And you can scuff it with sandpaper and THEN put it out in the sun. This can make a huge difference in fully curing as it allows possibly trapped solvents to flash off.
