We are one week into October. Temps are starting to sink around the country. The first major blizzard has already hit South Dakota.
If you are planning an epoxy coating project North of the Mason-Dixon line time is of the essence.

A few things to remember:
*Coatings take the temperature of the floor not the air, almost immediately.
Therefore, raising the air temp is not enough in most cases.
*Epoxy Coatings will have extended cure times as most products are tested at 70-75 degrees Fahrenheit.
*Epoxy that normally cures 6-8 hours at 77 deg f. may take 24-32 hours at 40 deg f.
*Keep epoxy in heated room until you are ready to mix (mixes easier and more completely).
*A heated garage that is surrounded by cold outside air will have cold spots at the door and the walls, be cognizant of this before walking onto the floor or top-coating.
*If below the suggested working temperature for epoxy consider a Polyaspartic/Polyurea coating as they can be used in colder temps without issue- check mfg's recommendations.

Hope this helps. When in doubt contact the manufacturer for best advice.

Scotty thanks for sharing that info. Seeing as I'll be rolling your epoxy and primer next weekend I'll ask for your advice. What is the minimum temp I should roll the primer and epoxy. Looking at temps for next weekend here in Oklahoma highs will be in the mid 70's and lows in upper 40's. Using my laser temp gauge the concrete averages about 10 degrees hotter in the morning then the outside air. Also what would be max humidity. Thanks in advance for your help and info.

You are still fine. We are still selling epoxy to folks in Maine!
I posted these tips as the cold-weather states are starting to get cold.
Max Humidity is 85%.

Can't wait to see your project!!

Thanks for the tips! I have been putting off doing the garage for a year or so now. I planned on doing this last month but three separate car repairs and a hot water heater dying has put this off until the spring/summer.
