About this product

An epoxy primer with a recoat window measured in weeks: 24 hours minimum, 1 month maximum, shortening to 1 week under a polyurethane topcoat.

Using this specific product

Resene Armourcote 210 Primer is listed here as the Epoxy primer (RA35) version for steel and structural steel. 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 (RA35); related versions can use different timing.
  • For steel and structural steel, pay particular attention to surface preparation, film thickness, temperature, dew point and pot life.
  • At 21°C. It is 1 week before a two-pack polyurethane topcoat.

How to check readiness

Check dry film thickness and the recoat window before the next coat. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. The sheet allows up to 1 month before recoating. 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.
