Sealcoating in Grove Hill, AL

Sealcoating · Grove Hill, AL

Sealer goes down on a clean, sound surface

Sealcoating is a coating that goes over sound asphalt. It slows down what sun, rain and leaking oil do to the surface. We seal driveways and parking lots from our yard in Grove Hill. On the Baldwin County side, the work runs out of our second yard in Robertsdale. A home driveway and a church lot get the same steps.

The surface gets swept and washed first. Cracks wide enough to hold sealant get hot-pour crack filling before anything else. Oil and grease spots get scrubbed and primed, or the sealer will not stick to them. Then the sealer goes down by squeegee or spray, with the edges cut in by hand. Drives and lots that carry steady traffic get a second coat once the first is dry.

What We Handle

  • Sealcoating for asphalt driveways, parking lots, church lots and shop yards
  • Surface swept, blown and washed before any sealer goes down
  • Hot-pour crack filling on cracks wide enough to hold sealant
  • Oil and grease spots scrubbed and primed so the sealer bonds
  • Sealer put down by squeegee or spray, with edges cut in by hand
  • A second coat at right angles to the first on busy lots
  • Barricades kept up until the sealer and fresh paint can take traffic
  • Parking lots laid back out and restriped after the sealer cures

What does sealcoating do for asphalt?

Sealer protects asphalt from the natural aging that sunlight, water and debris cause. That comes from the Pavement Coatings Technology Council, the sealer industry's technical group. Sealer also protects the pavement from leaking oil and gasoline. On a parking lot, those drips land in the same stalls day after day.

What sealer does not do is add strength. It is a coating on top, not a new layer of asphalt. It will not carry weight, close a wide crack or hold a failed base together. Pavement that moves under your tires needs the base fixed.

The same council is plain about the limits. Wide cracks, heavy alligator cracking and soft or sunken spots mean something else. The pavement or the base has failed. That gets repaired or replaced before any sealer goes on. Sometimes the answer is cutting out and patching the failed areas. Sometimes it is a new layer of hot mix over the old surface.

Asphalt sealing on new pavement, and how often to reseal

New hot mix asphalt has to cure before any sealer goes on it. That is true whether we did the asphalt paving or someone else did. The council puts the cure for hot mix at 30 to 90 days. Long hot weeks in a south Alabama summer move it along.

Curing and needing sealer are two different things. The Asphalt Institute says a well built asphalt driveway or lot should not need sealing for 2 to 5 years. How long depends on the climate and on how well the pavement was built. After the first one, the council's own cost comparison runs a home driveway on roughly a three year cycle.

Heat, sun and heavy rain are hard on pavement in this part of Alabama. A lot that takes trucks every day wears its sealer faster than a driveway holding two cars. We look at the surface, the cracks and the oil spots, then tell you what it needs.

Weather sets the schedule down here. The council's conditions are plain. The air has to be 50 degrees and rising. The pavement has to be 60 degrees and rising. No sealer goes down if rain is likely. Heavy morning dew has to burn off first, because sealer does not go on wet pavement.

Drying matters as much as the hour we spray. Ideal conditions are above 70 degrees, direct sun and humidity under 60 percent. Overcast skies and heavy humidity stretch the drying out. It can take up to 24 hours before the film will stand a rain event. On the coast here, July is the wettest month of the normal year and October the driest. A humid August morning in Robertsdale is not a dry October afternoon in Clarke County.

Busy lots get two coats, with the second laid at right angles to the first. The second coat only goes on after the first has dried through. Barricades stay up until the sealer and any fresh paint are hard enough for traffic. We plan the work in phases with you so part of the lot stays usable. Once the sealer cures, we come back and lay the stalls back out.

FAQ

Sealcoating Questions, Answered

Common questions about sealcoating across south Alabama, about 100 miles around Grove Hill, from the Black Belt to the Gulf Coast. If yours is not here, call and ask.

Call (251) 589-9970

What does sealcoating cost?
The price comes down to the square footage and the shape the pavement is in. Cleaning, crack filling, the number of coats and the mileage from our yard all move it. Oil spots and faded lines add work. We come out, look at the job, measure it and give you a written quote.
How long do I stay off the driveway after sealcoating?
Until the sealer has cured, which takes longer than it takes to dry. Sealer that is dry to the touch will take foot traffic but not vehicles. Hot sun and low humidity speed the cure up. A muggy, overcast day stretches it out, so we give you the time before we leave.
Can you seal a driveway with potholes and wide cracks?
No. Sealer over a broken driveway hides the problem for a season and nothing more. Wide cracks, alligator cracking and soft or sunken spots mean the pavement or the base has failed. That work comes first. There is more on this in our Alabama driveway sealcoating guide.
How soon can a new asphalt driveway be sealed?
Not right away. Hot mix asphalt usually cures in 30 to 90 days, and it needs that time before sealer goes on. A well built driveway will not need sealer for a few years after that. Sealing early traps what is still working its way out of fresh asphalt.
Do you restripe the parking lot after sealcoating?
Yes. Fresh sealer covers the old stalls, arrows and fire lanes. The lot gets laid back out once the sealer is hard. Barricades stay up until the sealer and the new paint can take traffic. Accessible spaces and access aisles get marked back in on the same trip.
What time of year is best for sealcoating in south Alabama?
Warm, dry stretches with real sun. Sealer needs the air at 50 degrees and rising, the pavement at 60 degrees and rising, and no rain coming. Late spring through early fall gives the most workable days here. Summer afternoon storms can shut a job down, so we watch the radar.
