Using this specific product

Black Jack (Gardner-Gibson) CAS-73 Driveway Sealer is listed here as the Coal-tar-free driveway sealer version for asphalt driveways. For filling or sealing asphalt, 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 Coal-tar-free driveway sealer; related versions can use different timing.
  • For asphalt driveways, pay particular attention to pavement temperature, sun, humidity, depth of fill and rain in the forecast.
  • The source gives no conditions for this time.

How to check readiness

Check that the surface is firm, then keep traffic off for the stated time. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required. 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

Sealer feels dry long before it will take a turning tire; wheels need the longer time.
