AVERAGE DRY TIME: Dries to the touch in 12 hours. Lower temperatures & higher humidity will slow down drying times. Second coat can be applied with no sanding required after 24 hours.

Does epoxy need air to cure?

Air temperature is most often the ambient temperature unless the epoxy is applied to a surface with a different temperature. Generally, epoxy cures faster when the air temperature is warmer. Exothermic heat is produced by the chemical reaction that cures epoxy.

Will epoxy cure at 60 degrees?

We know that most epoxies perform well or, at least reach a higher percentage of their potential physical properties, at temperatures of 60 °F and above. Some resin /hardener combinations are formulated to cure in temperatures as low as 35°F.

Is epoxy hard to use?
