Using this specific product
Sika Sikafloor-71 TC Pronto is listed here as the Fast-curing floor topcoat (formerly MTop SRS 71TC) version for floors and cold-weather 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 Fast-curing floor topcoat (formerly MTop SRS 71TC); related versions can use different timing.
- For floors and cold-weather coating, pay particular attention to mix ratio, batch size, temperature and pour thickness.
- The sheet states no temperature for this time. It says it cures at temperatures down to 24°F.
How to check readiness
Check the coolest or thickest part for firmness before sanding, demolding or loading. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.

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