Hello all. I've tried searching the archives, LMI and even the System Three website but I can't find any definitive information about curing time. By the way, I don't think LMI carries it anymore.

I seem to recall reading 24 hrs. This is what I did on my first gap filling round. I find this a long time to wait, though. I finished round 2 last night around 10 and this morning, around 6'ish, I found that the 'coat' I had on there seemed as hard and dry as it was going to get. 8 hours seemed to do it.

Have any of you experienced success with short curing periods? Thanks in advance. Regards,

Alain

as an adhesive it is cured in 3 hours but that is not good enough to sand. you need to let it cure for 24 hrs before sanding or it will gum and wrinkle. Hard to the touch does not mean it is completely cured. Epoxy will cure faster on the out side of the film than the middle of the film. You could probably get away with 12-16 hrs but 24 is will insure it is complete. When reading labels on epoxy keep in mind that most are written for adhesive non sanded uses. If you need to sand any epoxy wait 24 hrs.MichaelP38904.5101041667

I've never used System Three, but I've done a lot of work with epoxy, mostly for boatbuilding (using MAS brand, which I like a lot) .

Epoxy cure times depend A LOT on the temperature. It might take three or four times as long to get really hard at 60F compared to 80F. Working times get really short at higher temperatures, too.

Hey bud, it looks like you're well on your way to beat me to the finishing line! WTG!

You talking to me? I did not know there was a finish line

I find that the lower the humidity and the hotter it is I it plenty dry in 8 hours. It is very important to just fill the pores so use a squeegeeeeeeeeeeeeeeee
