Epoxy processing at cold temperatures

We regularly receive questions about processing epoxy and other resins in winter. In this article we explain what you should pay attention to and what you should and shouldn't do if you are going to pour epoxy in winter at low temperatures. We have some useful tips!

What is the ideal processing temperature of epoxy?

The ideal processing temperature of epoxy is 20°C. It is therefore best to process epoxy at room temperature. At lower temperatures, epoxy will cure less quickly compared to higher temperatures. On the other hand, you have a longer processing time at low temperatures. 

Sometimes it is necessary to process epoxy in colder conditions, for example if you have to work with epoxy in winter. In order to carry out the work successfully, we have listed a few tips for you.

Tips for processing epoxy at cold temperatures:

  • See if it is really necessary to work in the cold. Can the workpiece be moved to a warmer place? 

  • Choose a faster type of epoxy. These can be processed better at a lower temperature than slow epoxy resins.

  • Preheat the environment if you can. Sometimes you can go a long way with a heater, a few pieces of foil and some tape.

  • Avoid a cold wind. For example, if you are going to carry out a repair on a boat, try building a tent around the repair. Or attach a tarpaulin around the entire boat with tape.

  • Choose a warmer day. Is it 6 degrees today and 11 degrees tomorrow? Then schedule the job tomorrow.

  • Process the epoxy in the morning, but only after the dew has disappeared. The epoxy then has the hottest part of the day to harden.

  • Preheat the epoxy. Make sure it is at least room temperature when you start.

  • Use narrower, taller mixing cups to mix your epoxy in, rather than wide, wide roller trays.

  • Accept a less than optimal result. Because the epoxy hardens more slowly, there is also a greater chance of contamination in the surface, moisture deposits and dullness. As a rule, this is in the surface and you can easily sand it away.

Werken met epoxy in de winter is dus niet ideaal, maar zeker wel mogelijk. Hetzelfde geldt eigenlijk voor de zomer. In een ander artikel geven we je graag tips over het verwerken van epoxy bij hogere temperaturen!

Processing epoxy in winter is therefore not ideal, but it is certainly possible. The same is true for summer. In another article we would like to give you tips about processing epoxy at higher temperatures!
