Using this specific product

System Three MirrorCoat is listed here as the Two-part epoxy table-top and bar-top resin version for bar top, table top, and epoxy coating. For mixing and curing epoxy, 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 Two-part epoxy table-top and bar-top resin; related versions can use different timing.
  • For bar top, table top, and epoxy coating, pay particular attention to mix ratio, batch size, temperature and pour thickness.
  • At 25°C (77°F).

How to check readiness

Check the coolest or thickest part for firmness before sanding, demolding or loading. Working time is 40 minutes for a 100 gram mix. 90% cure is reached in 72 hours. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.

Avoid this mistake

A larger batch can heat faster while a thin film may cure more slowly.
