Driveway Sealcoating questions, answered by experts

If your asphalt driveway shows cracks, potholes, or standing water, it’s likely time for a repair. Cracks, big or small, let water seep in, weakening the base and causing further damage. Potholes are a sign of this weakening process in action while standing water suggests your driveway has poor drainage, which can cause even more issues. You may also see warping or buckling—a sign of a compromised base layer—or sinking pavement. Spotting these signs early on can help you save yourself a bigger repair bill in the future.

The three most common types of asphalt are hot asphalt, MC cold mix, and UPM asphalt. Hot asphalt is used most often for paving and patching roadways while it’s hot and workable. MC cold mix asphalt cures more slowly than hot asphalt, but it can be used for temporary patches and repairs in low-traffic areas. UPM is also used cold, but it can be used as a longer-term fix, usable in almost any conditions at almost any temperature.

Sealing coat asphalt after 6-12 months and then every 2-3 years is recommended.

We don’t recommend sealing brand-new asphalt; instead, wait for at least three months so that the asphalt has some time to cure. If it’s applied too soon, the seal coat can trap oils and chemicals in the asphalt, preventing it from fully curing and leading to a weaker surface that’s susceptible to damage. 

Yes, most repair services include sealing to protect the surface. Confirm with your contractor.
