: How long does the epoxy take to cure in, say, 55 degrees, 65 degrees, and 75
: degrees, assuming low relative humidity? Would 45 degrees be a bad idea?
: The reason I ask is that although I will do the epoxy work in the daytime
: to take advantage of the greenhouse effect, nighttime temps drop
: drastically in this dry climate. Yes, I can put in some lightbulbs for
: warming, and I plan on keeping a portable oil-filled electric radiator
: handy. There is also a little heat coming from the adjacent studio, which
: has a forced-hot-air heater. I just wanted to know what the temperature
: limits for a strong cure were.

: Thanks for any help with this.

In 80-degree heat slow setting Raka set tack free in about a day. A couple of weeks ago using US Composite’s slow set, the epoxy was in 50 degree weather and set tack free in three days.
