Seal it, or stripe it?

They are two different jobs that solve two different problems. Here is what each one does, and why the smartest move is usually both.

People often use sealcoating and striping like they mean the same thing. They do not. One protects the asphalt itself, the other organizes what happens on top of it. Knowing the difference saves you money and helps you plan the work in the right order. Here is the plain English version.

What sealcoating does

Sealcoating is a protective layer applied over the asphalt. Sun, rain, freeze and thaw cycles, oil, and salt all break asphalt down over time, and a Long Island winter is especially hard on it. A sealcoat shields the surface, slows cracking, and restores that deep, uniform black that makes a lot look new again. Think of it as sunscreen and a fresh coat of paint for the pavement in one step. It extends the life of the asphalt and delays far more expensive repaving down the road.

What striping does

Striping is everything painted on top: stalls, arrows, crosswalks, fire lanes, ADA symbols, and every other marking that tells drivers and pedestrians where to go. Striping is about safety, capacity, compliance, and first impressions. It does not protect the asphalt, it directs how the lot is used. If you want the full picture on the marking side, see when to restripe your parking lot and our ADA compliance guide.

Why they belong together

Here is the key: sealcoating covers everything, including your existing lines. So if a lot is due for a sealcoat, that is the perfect moment to restripe, because the old lines are going under the new coat anyway. Sealing first, then striping over the fresh, clean surface gives you the sharpest, longest lasting lines and a lot that looks completely renewed. Doing them in the wrong order, or striping over a surface that should have been sealed, just means paying to redo it sooner.

Seal first, stripe second. The result is a lot that looks brand new, top to bottom.
