About this product

A micaceous iron oxide intermediate coat. Its sheet lists handle and recoat at the same time at every temperature, 18 hours at 4°C down to 2 hours at 32°C, and has no separate full cure.

Using this specific product

Carboline Carboguard 880 MIO is listed here as the Micaceous iron oxide epoxy version for steel structures, bridges, and intermediate coat. 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 Micaceous iron oxide epoxy; related versions can use different timing.
  • For steel structures, bridges, and intermediate coat, pay particular attention to surface preparation, film thickness, temperature, dew point and pot life.
  • At 24°C. At 24°C, 100 micron dry film and 50% relative humidity. The source gives no conditions for this time.

How to check readiness

Check dry film thickness and the recoat window before the next coat. The data sheet gives a pot life of 4 hours at 24°C. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. Lift or move the item gently and avoid twisting the bond or pressing finished faces together.

Avoid this mistake

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