About this product

A solvent-based cure-and-seal with an unusually long traffic ladder: tack-free in 1 hour, light foot at 6, light cars at 24 and normal cars at 72 hours. The sheet asks for a second application at least two weeks after the cure coat, and says storage below 30°F makes the product thick and unusable.

Using this specific product

Sika Scofield CureSeal 350 is listed here as the Solvent-based non-yellowing curing and sealing compound version for concrete curing and decorative concrete. For repairing concrete or masonry, 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-based non-yellowing curing and sealing compound; related versions can use different timing.
  • For concrete curing and decorative concrete, pay particular attention to substrate moisture, depth, temperature and protection from traffic.
  • At 70°F (21°C).

How to check readiness

Check the slowest, coolest section before loading or coating. The data sheet lists tack free at 1 hour. Try a protected edge first and avoid turning, dragging or concentrated loads. Open the area gradually and keep heavy or hot tires off until the full stated milestone.

Avoid this mistake

Early strength, coating readiness and full cure are separate decisions.
