Amine blush risk: This epoxy can develop a waxy surface film at high humidity or when the substrate is near the dew point. The calculator will warn you if your conditions trigger this risk.

When this estimate may be unsafe

  • - The joint, bead, pour, or repair is thicker than the product data sheet assumes.
  • - The substrate is colder than the surrounding air, wet, oily, dusty, painted, or otherwise poorly prepared.
  • - The repair will carry weight, resist water pressure, or be safety-critical before full cure.
  • - The surface is near the dew point or humidity is high enough to create amine blush.

Quick answers

How long does Epoxy Quick Set take to cure?

Epoxy Quick Set fully cures in 24 hours at standard laboratory conditions, usually 70°F / 21°C and 50% relative humidity. At colder temperatures or difficult humidity, cure time can increase significantly.

What is the minimum temperature to use Epoxy Quick Set?

The minimum application temperature for Epoxy Quick Set is 39°F (4°C). Applying below this threshold can prevent proper curing and cause the bond or seal to fail.

How long does Epoxy Quick Set take to cure in cold weather?

Cold temperatures significantly extend cure time. As a rule of thumb, every 18°F (10°C) below 70°F can roughly double cure time. Enter your actual temperature in the calculator for a product-specific estimate.

Does humidity affect Epoxy Quick Set cure time?

Minimal effect. Epoxy Quick Set is a two-part chemical reaction so ambient humidity has little influence on cure rate. Temperature is the primary variable. Use the calculator above for adjusted estimates.

How long do you need to clamp Epoxy Quick Set?

Epoxy Quick Set requires a minimum of 10 minutes of clamping at standard conditions. In cold or humid conditions, extend clamp time before moving the assembly.

What is the open time for Epoxy Quick Set?

Epoxy Quick Set has a working open time of 10 minutes at standard conditions. At higher temperatures open time may shorten; at lower temperatures cure may slow after assembly.

Does Epoxy Quick Set get amine blush?

Yes. Amine blush can form when this epoxy cures in high humidity or near the dew point. Wash the surface and lightly abrade before recoating or bonding over it.
