About this product

An epoxy primer with a long pot life, 6 hours at 25°C, and an overcoat window that stays open for 12 months once the minimum is passed.

Using this specific product

International (AkzoNobel) Intergard 251 is listed here as the Epoxy primer version for steel priming. For coating steel or industrial surfaces, 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 Epoxy primer; related versions can use different timing.
  • For steel priming, pay particular attention to surface preparation, film thickness, temperature, dew point and pot life.
  • 10 hours at 10°C, 8 at 15°C and 3 at 40°C. 2 hours at 10°C, 1 hour at 15°C and 30 minutes at 40°C. The same as hard dry at each temperature. 7 hours at 10°C, 5 hours at 15°C and 2 hours at 40°C.

How to check readiness

Check dry film thickness and the recoat window before the next coat. The sheet gives a pot life of 6 hours at 25°C. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required.

Avoid this mistake

Recoat windows can close; past the maximum, abrading is usually required.
