Sealcoating for Broward County Parking Lots and Drives

Under the South Florida sun, a black parking lot can fade to a dull, chalky gray within a few years. That color change is the visible sign of the asphalt binder drying out, and sealcoating is the routine maintenance step meant to slow it down. This page explains what sealcoat really does, what it cannot do, how weather in Fort Lauderdale affects when it can be applied, and how a plaza, office park, church or HOA can plan the closure. When you send a request through this site, it goes to an asphalt contractor working Broward County, who looks at the pavement, decides whether it is a good candidate for sealing, and quotes the job. We are a connection service, not the contractor, and we do not apply sealcoat ourselves.

What sealcoat actually does

Asphalt pavement is stone held together by a petroleum-based binder. Sunlight, heat, oxygen and water gradually break that binder down. As it oxidizes, the surface stiffens, shrinks and begins to lose the fine particles that fill the gaps between larger stones. That process is called raveling, and it leaves a rough, porous surface that lets more water in.

Sealcoat is a thin liquid coating, typically spread or sprayed in two coats, that dries into a protective film over the top of the pavement. It shields the binder from ultraviolet light, slows the entry of water, resists damage from gasoline and oil drips, and restores a uniform dark finish. It also gives freshly painted stripes a clean background, which is why sealing and restriping are often done together.

What sealcoat does not do

Sealcoat is a surface treatment. It adds no structural strength and will not hold up a pavement whose base has failed. Applied over alligator cracking, potholes or ruts, it may make the lot look better for a season, but the underlying damage keeps progressing and soon breaks through the new coating.

It also does not fill cracks of any real width. Sealcoat bridges hairline surface checking at most. Open cracks need to be filled or sealed separately beforehand, and broken areas need patching. If a proposal offers to seal a lot that is visibly breaking up without mentioning repairs first, that is a sign to ask more questions.

Why the sun matters more than anything else here

In many parts of the country, freeze-thaw cycles are the main thing that destroys pavement. In Broward County, it is ultraviolet exposure all year long, combined with surface temperatures that climb well above air temperature on summer afternoons. There is no winter break from the sun. A lot facing open sky along Federal Highway or in an exposed warehouse yard in the Port Everglades area takes that exposure every day.

Near the beach and the Intracoastal, salt air adds another stress, and frequent rain keeps surfaces wet for long stretches. Each of these speeds up oxidation. That is why owners here often notice fading, surface cracking and loose aggregate sooner than they expected, and why a regular sealing schedule is part of keeping asphalt in service longer.

Fix cracks and failed spots before sealing

The correct order of work is repair, then crack fill, then seal, then stripe. Skipping the first two steps is one of the most common shortcuts in sealcoating.

Cracks should be cleaned of dirt, sand and vegetation, dried, and filled with a hot-applied rubberized crack sealant or a suitable filler, depending on width. Broken areas and potholes should be cut out and patched with new asphalt. Oil stains, which are common in parking stalls and at drive-throughs, should be cleaned and primed so the sealer adheres instead of peeling off. Only then is the surface ready for sealcoat.

Crack filling keeps water out of the base, which sealcoat alone cannot do.
Patching first means the new coating goes over sound pavement instead of loose debris.
Oil spot treatment prevents dark blotches from bleeding through or flaking later.
Edging along curbs and sidewalks keeps sealer off concrete and landscaping.

Timing sealcoat around the rainy season

Sealcoat needs dry conditions to cure. Rain that arrives before the coating has set can wash it off the pavement and onto sidewalks, gutters and storm inlets. In Fort Lauderdale, afternoon thunderstorms are a near-daily pattern from roughly late spring through fall, and they can build quickly on days that start clear.

Contractors working this area plan around that. Summer jobs often start early so both coats are down and setting well before the clouds build. The drier months, roughly late fall into spring, give more forgiving windows, and many properties schedule sealing then on purpose. If a forecast turns, a responsible contractor will reschedule rather than push through, and that flexibility is worth agreeing on in advance.

Heat and humidity also affect drying. Coatings can skin over quickly in direct sun while the layer underneath stays soft. Ask how the contractor decides when the surface is ready for foot traffic and when it is ready for vehicles.

How often a Broward County lot should be sealed

There is no single interval that fits every property. A lightly used church lot with large shade trees will wear differently from a fast-food drive aisle or a truck court at a distribution building. Many property owners in South Florida reseal every few years, adjusting based on how quickly the surface fades and starts to show wear.

A practical approach is to watch the pavement rather than the calendar. When the black finish has turned gray in traffic lanes, when small stones are loosening, or when fine surface cracks are appearing, it is time to have the contractor look. Sealing too often is also a problem: thick buildup from repeated coats can crack and peel, so the coating should be worn before more is added.

Planning the closure for a business, church or HOA

Sealcoating requires the treated area to be empty of vehicles and people until it has set. For a property that depends on parking, that is the biggest planning challenge, and it is worth thinking through early.

Pick the lowest-traffic days of the week. For many offices that is a weekend; for churches it is usually midweek.
Ask the contractor to divide the lot into sections so part of it stays open while the rest cures.
Notify tenants, residents or members at least several days ahead, with a map of closed areas.
Arrange for overnight vehicles, such as company vans or resident cars, to be moved before work starts.
Plan for deliveries, trash pickup and emergency access during the closure.
Agree on how barricades and tape will stay in place until the area reopens.
Schedule restriping right after the sealer is ready, so the lot is not left without stall lines.

Keeping tracking off floors and sidewalks

Uncured sealer sticks to shoes and tires and ends up on lobby floors, carpet and sidewalks. Good barricading and clear signage at every pedestrian entrance matter as much as the coating itself. If your building has several doors that open onto the lot, walk the site with the contractor and decide which entrances need to be roped off and which will remain usable.

Questions to ask before choosing a sealcoat proposal

Sealcoat proposals can look nearly identical while describing very different jobs. These questions help separate a thorough plan from a quick spray-and-go.

What type of sealer will be used, and how will it be mixed or diluted?
How many coats, and will the second coat wait until the first has dried?
Will sand or another aggregate be added for traction in walkways and drive lanes?
Which cracks will be filled, and with what material?
Are any areas being patched, and are those repairs priced separately?
How will oil spots be cleaned and primed?
What happens if rain arrives before the coating cures?
Is restriping included, and will the layout stay the same or be updated?

Is your pavement a good candidate?

Sealcoat pays off most on asphalt that is still structurally sound. Lots that are fairly new, recently overlaid, or in decent shape with only fading and fine cracking are ideal. If more than a small portion of the lot shows alligator cracking, potholes or settled areas, the contractor may advise repairs or even an overlay first. That is not upselling; sealer over failing pavement simply does not last.

Not sure where your lot falls? Send a request with a few photos and a description of what you are seeing. The contractor can tell you on the site visit whether sealing makes sense now, what prep work it needs, or whether the money is better spent elsewhere.

Sealcoating for Broward County Parking Lots and Drives — common questions

Does sealcoating make my parking lot last longer?

It helps the surface resist the sun, water and fuel spills that break down asphalt binder, so it slows the aging that leads to raveling and cracking. It does not add strength, and it cannot fix a failed base. Its value comes from applying it to pavement that is still sound and repeating it at sensible intervals, along with crack filling and timely repairs.

How long does a lot need to stay closed after sealing?

Drying time depends on temperature, humidity, sun, shade and the product used. Foot traffic is usually allowed sooner than vehicles. Many projects in South Florida close an area for most of a day, sometimes longer in humid or shaded conditions. The contractor should tell you the expected reopening time for each section and confirm it on the day based on how the coating is setting.

What happens if it rains right after sealcoating?

If heavy rain falls before the sealer has set, it can wash off, leaving streaks on the pavement and residue on curbs, sidewalks and inlets. That is why contractors in Broward County watch forecasts closely and often start early in summer. Before signing, ask how the contractor handles weather delays and what is done if a sudden storm reaches freshly coated pavement.

Can you sealcoat over cracks?

Sealer by itself will not close cracks of any meaningful width; water still gets through and the crack soon reappears. Cracks should be cleaned, dried and filled with a proper crack sealant before the coating goes down. Areas with many interconnected cracks or potholes should be patched first. A proposal that skips crack treatment entirely is leaving out the part that protects the base.

How often should we sealcoat in Fort Lauderdale?

It varies with traffic, shade and exposure. Many South Florida owners reseal every few years, but the better guide is condition. When drive lanes have faded to gray, loose stones appear, or fine surface cracks start showing, it is time for an assessment. Sealing far more often than needed can build up thick layers that crack and peel, so frequency should follow wear.

Do we need to restripe after sealcoating?

Yes. Sealcoat covers existing paint, so stall lines, arrows, fire lane markings and accessible parking symbols all need to be repainted once the surface is ready. Most owners schedule striping immediately after sealing so the lot reopens with clear markings. It is also a good moment to update the layout if you want to change traffic flow or add accessible stalls.

Who applies the sealcoat if we request it through this site?

This website does not perform the work. Your request is sent to an asphalt contractor working Broward County, who contacts you, inspects the pavement, and recommends whether sealing fits your lot and what prep is needed. The scope, schedule and price come from the contractor after the visit, and you decide whether to proceed, with no obligation to move forward.
