Shop name for the induction or standing time, typically 10 to 30 minutes, that some epoxies need after mixing so the resin and curing agent start reacting before application. Skipping sweat-in, especially in cold weather, invites amine blush, poor cure and a soft film. Data sheets list it next to pot life, and the clock starts once the components are fully mixed.
Give that epoxy its sweat-in, twenty minutes, before you load the pump, it's too cold to rush it.
