Industrial protective coatings

Film-build schedule

Recoat has a floor and a ceiling, and film thickness moves both

  1. Prepare the surface and apply the Epoxy coating with temperature-banded recoat and cure table to the stated thickness
  2. Recoat inside the window the data sheet gives
  3. Return to service only at the stated cure

This product’s stated stages Quoted at 75°F

  • Ready for another coat4 hours
  • Full cure1 day
  • Immersion-ready5 days
  • Recoat window closes30 days

Worth noticing: Recoat inside the window: not before 4 hours and not after 30 days.

Common mistake: Recoating after the maximum window has closed; the next coat may not bond without abrading.

About this product

An epoxy whose data sheet runs on a temperature ladder: recoat falls from 12 hours at 50°F to 2 hours at 90°F, and immersion service is barred entirely at 50°F. Pot life is 3 hours at 25°C.

Using this specific product

Carboline Carboguard 890 is listed here as the Epoxy coating with temperature-banded recoat and cure table version for steel coating and immersion service. 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 coating with temperature-banded recoat and cure table; related versions can use different timing.
  • For steel coating and immersion service, pay particular attention to surface preparation, film thickness, temperature, dew point and pot life.
  • It is 90 days over polyurethane. It is 12 hours at 50°F, 8 hours at 61°F and 2 hours at 90°F. It is not recommended at 50°F, 10 days at 61°F and 3 days at 90°F. It is 3 days at 50°F, 2 days at 61°F and 16 hours at 90°F.

How to check readiness

Check dry film thickness and the recoat window before the next coat. The sheet gives a maximum recoat window of 30 days over epoxy. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required. Continuous immersion is more demanding than splashes; wait for the specific immersion milestone.

Avoid this mistake

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