About this product

A single-coat polyurethane deck coating (hence 'one shot'). The May 2026 sheet gives no recoat window for the coating itself, only for its primer, Sikadur-22 Lo-Mod FS, which must be overcoated within 36 hours after tack-free.

Using this specific product

Sika Sikalastic-720 One Shot is listed here as the Polyurethane deck coating version for deck waterproofing, balconies, and vehicular traffic. 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 Polyurethane deck coating; related versions can use different timing.
  • For deck waterproofing, balconies, and vehicular traffic, pay particular attention to substrate moisture, depth, temperature and protection from traffic.
  • At 75°F (24°C) and 50% relative humidity. At 70°F (21°C) and 50% relative humidity. The source gives no conditions for this time.

How to check readiness

Check the slowest, coolest section before loading or coating. The data sheet gives a pot life of 20 minutes. The data sheet says the coating should be tack-free after about 6 hours. 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.
