Using this specific product
Sika Sikafloor-2640 is listed here as the Solvent-free epoxy floor coating (UK) version for floors and garages. 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 Solvent-free epoxy floor coating (UK); related versions can use different timing.
- For floors and garages, pay particular attention to mix ratio, batch size, temperature and pour thickness.
- 30 minutes at +10°C and 15 minutes at +30°C. 3 days at +10°C and 1 day at +30°C. 12 hours at +10°C and 3 hours at +30°C. 24 hours at +10°C and 12 hours at +30°C.
How to check readiness
Check the coolest or thickest part for firmness before sanding, demolding or loading. The sheet gives a pot life of about 20 minutes at +20°C. The sheet gives a maximum overcoating wait of about 2 days at +20°C. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required.
Avoid this mistake
A larger batch can heat faster while a thin film may cure more slowly.
