About this product

A coal tar epoxy with one clean set of figures: 2 hours to touch, 24 hours to recoat and 7 days to immersion at 75°F.

Using this specific product

Tnemec Series 46-465 H.B. Tnemecol is listed here as the High-build coal tar epoxy version for pipe and tank coating and buried 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 High-build coal tar epoxy; related versions can use different timing.
  • For pipe and tank coating and buried steel, pay particular attention to surface preparation, film thickness, temperature, dew point and pot life.
  • The source gives no conditions for this time.

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. 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.
