How long does the room need to stay above 75°F after pouring epoxy?

For the full 72-hour curing stage, not just until the epoxy is dry to the touch and not just the first 24 hours. 75°F is the minimum room temperature for UltraClear Bar & Table Top Epoxy, and if the room drops below 75°F at any point during those first 72 hours, the epoxy will not cure as intended. Below 75°F the heat from the curing epoxy stays trapped inside, and the result is a completely cloudy surface. Six hours of warmth is not enough.

This is a requirement, not a recommendation, and there is no room for variance. A few practical points:

- Thermostats are not always accurate, so set yours a few degrees warmer than 75°F to be sure the minimum is met. - Use a space heater to warm the room if needed, but do not point a heat lamp at the epoxy. It's the room that needs to be above 75°F, not the epoxy itself, and a heat lamp can overheat it. - If you can't keep a large space warm, tent off the area around the piece with painter's plastic and run a small space heater inside the tent.

Plan the pour for a time when you can hold the temperature for three full days. If the room dropped below 75°F partway through, the epoxy will not cure as intended and can come out cloudy.
