About this product

A traffic top coat that cures in 12 to 14 hours but holds foot traffic for 48 and vehicles for 72, so cure and use are not the same thing.

Using this specific product

Sika Sikalastic TC-225 HT is listed here as the High-temperature traffic top coat version for parking decks and traffic coatings. For coating or sealing a roof, 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-temperature traffic top coat; related versions can use different timing.
  • For parking decks and traffic coatings, pay particular attention to roof temperature, dew, rain in the forecast, film thickness and how many coats are needed.
  • At 70°F and 50% humidity. The source gives no conditions for this time. At 73°F.

How to check readiness

Check that the surface is dry and that no rain or dew is forecast inside the stated window. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required. The sheet gives foot traffic at 48 hours. The sheet gives vehicle traffic at a minimum of 72 hours.

Avoid this mistake

Rain resistance and walkable are earlier milestones than the full cure the roof system is rated for.
