Black Jack

Black Jack driveway sealers and roof coatings help homeowners, maintenance crews and contractors seal asphalt and repair or coat roofs. Its no-stir driveway formulas keep particles suspended for an even finish without stirring a heavy pail.

Black Jack makes roofing, road and waterproofing products. Its product history dates to 1913. It is a brand of ICP Building Solutions.

Driveway sealer starts with repaired asphalt

Black Jack driveway sealers belong on blacktop and asphalt. Where the driveway meets concrete or brick, mask the adjoining surface and tape the sheeting edges down to keep sealer from wicking underneath.

Large holes and cracks need patching before driveway sealer goes on. That repair comes first. Clean and degrease the pavement, patch the damage, and leave the surface free of puddled water before sealing.

The brand offers both no-stir gel formulas and E-Z stir products. Check the selected formula’s mixing directions before opening the pails. Material needs also depend on the pavement: a driveway that’s gone a long time between sealings takes more sealer to fill developed pores and cracks. Measure the area and use the selected product’s coverage guidance.

Thin coats give you control

Use two thin coats. A heavy coat cures less evenly and is prone to puddling and tracking; a second thin coat fills areas the first pass missed. Spread the sealer with a rubber squeegee, a bristled driveway broom, or both, working out puddles as you go.

You can usually drive on the finished driveway 24–48 hours after the last coat. Cool surfaces, shade, humidity and thick spots can extend that wait. Press into the sealer to check that it’s dry through its full thickness, and keep vehicles off if black material transfers to your glove.

Roof and foundation work needs a closer match

For a roof coating, identify the roof material and the existing finish first. A coating needs a firm surface to hold onto. Remove loose material and repair damaged areas before coating, then match the coating label to the roof material and existing finish.

Black Jack’s white roof coatings reflect sunlight to reduce roof temperatures, which can lower indoor temperatures and cooling needs.

For foundation work, identify whether you’re dealing with soil moisture, a leaking joint or water under pressure. That distinction determines the treatment. Match the coating’s labeled use to the foundation surface and water exposure.

Frequently Asked Questions

What is Black Jack roof sealant used for?

Black Jack’s roof products cover repairs and protective coatings, but they aren’t interchangeable. Eterna-Kote is a silicone roof coating; the right choice for your roof depends on the surface and the coating’s labeled use.

Does Black Jack driveway sealer fill cracks and potholes?

Sealer won’t repair large cracks or potholes. Black Jack recommends Crack Stopper for areas with cracks measuring ½ to ¾ inch and RePave Pothole Patch for holes larger than 4 inches. You need those repairs finished before sealing.

How long does Black Jack driveway sealer take to dry?

You can usually drive on Black Jack driveway sealer 24–48 hours after the last coat, but cracks can stay wet longer than the surrounding pavement. A toothpick pushed into a crack gives you a useful check: if it comes out black and wet, the sealer hasn’t cured through.

Do you have to stir Black Jack driveway sealer?

It depends on the formula you’re using. Black Jack offers no-stir gel formulas as well as E-Z stir products, so follow the mixing directions on your pail. Mixing material between pails helps keep the sheen consistent across the driveway.
