Using this specific product

Sika Sikafloor-315 N is listed here as the UV-resistant urethane floor coating version for floor coating, urethane, and UV-resistant. For installing or finishing a floor, 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 UV-resistant urethane floor coating; related versions can use different timing.
  • For floor coating, urethane, and UV-resistant, pay particular attention to subfloor condition, trowel coverage, room temperature and traffic plan.
  • 50 minutes at 50°F and 15 minutes at 86°F. 72 hours at 50°F and 24 hours at 86°F. 18 hours at 50°F and 8 hours at 86°F. 3 days at 50°F and 36 hours at 86°F. 10 days at 50°F and 5 days at 86°F.

How to check readiness

Test the least-ventilated area before walking, covering or replacing furniture. The product page gives a pot life of 25 minutes at 68°F. The product page gives a maximum recoat of 48 hours at 68°F. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required.
