How does cold weather affect epoxy resin?

Cold temperatures can affect epoxy resin in several different ways:

Curing time: More frigid temperatures slow down the curing time for the epoxy resin. This may be beneficial if you are looking for a longer working time, but it also means that your project will take an extended amount of time to complete.

Product viscosity: In cooler temperatures, epoxy does not flow as smoothly. You may notice that the product seems much thicker than usual to pour and mix. If your product or surface is too cold, a self-leveling epoxy may not level properly and leave you with imperfections like fisheyes.

Humidity Problems: When you’re working in colder temperatures, increased humidity in the atmosphere may also affect your project. You may get moisture settling on the uncured epoxy which can lead to blushing, surface defects, or reduced shine/gloss.

Don’t worry if your epoxy has traveled through cold areas to get to you. Be sure to acclimate your epoxy back to the proper temperature (75°F) before use.
