Using this specific product

Permatex 5 Minute Epoxy is listed here as the Clear (all sizes) version for repair and bonding. For mixing and curing epoxy, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Clear (all sizes); related versions can use different timing.
  • For repair and bonding, pay particular attention to mix ratio, batch size, temperature and pour thickness.
  • Cooler temperatures may require longer set time.

How to check readiness

Check the coolest or thickest part for firmness before sanding, demolding or loading. Working time is 4 to 6 minutes. Epoxy sets in 5 minutes. Lift or move the item gently and avoid twisting the bond or pressing finished faces together.

Avoid this mistake

A larger batch can heat faster while a thin film may cure more slowly.
