Sealcoating
A layer that wears out so the asphalt does not
Sealcoat is sacrificial by design. Understanding that is the difference between maintaining a lot and being surprised by it.

What it actually is
Sealcoat is a sacrificial layer, and that is the point
Sealcoat is a thin coating applied over asphalt. It is not structural, it does not add strength, and it is not a repair. What it does is take the wear that would otherwise land on the asphalt itself: sun, water, and the fuel and oil that drip out of parked cars.
It wears down. That is not a fault in the product or a sign the job was done badly, it is the job. The coating is meant to be the thing that degrades so the binder holding your asphalt together does not. When it has worn thin, it gets reapplied, the same way a roof gets recoated and a wall gets repainted.
This matters for how you budget it. Sealcoating is a maintenance line item on a cycle, not a one-time fix you buy once and forget. Any contractor who lets you believe otherwise has made the next conversation harder for both of you.
Central Texas
Sun and water, in that order
Asphalt is aggregate held together by a binder. Almost everything that ages a lot is something attacking that binder, and in this part of Texas the sun does most of the work.
Ultraviolet light and heat oxidise the binder. It gets brittle, it loses its grip on the aggregate, and the surface goes from black to grey and starts to ravel. Once the surface is open, water has a route in, and water reaching the base is what turns a surface problem into a structural one.
- Sun and heat oxidise the binder and make the surface brittle
- A brittle surface ravels, which opens a path for water
- Water reaching the base is what turns a repair into a repaving
- Fuel and oil drips soften asphalt directly, which is why they show up first in parking stalls
Scope
What sealcoating will not do
Being clear about this up front saves an argument later, and it is the part most quotes leave out. Sealcoat is roughly the thickness of paint. Everything below is outside what it can do, and none of it gets better by coating over it.
- It will not fill cracks. Those are sealed as separate work, before the coating goes down
- It will not repair potholes or broken pavement. That is asphalt repair, and it comes first
- It will not fix a failed base. If the ground under the asphalt has gone, the surface is a symptom
- It will not add structural strength. A lot that is failing under load needs a different conversation
How the job runs
What happens on your property
- 01
We walk the lot
Before anything is quoted. We look at drainage, at where the surface has opened up, at the cracks, and at whether anything needs repair first. You get the scope in writing, including anything we think should happen before the coating rather than after it.
- 02
Sections and schedule, agreed first
Which part of the lot closes, in what order, on which nights. You get that in writing before the first day, so you can pass it to tenants without having to translate it.
- 03
Prepare, then coat
The surface has to be clean and dry for the coating to bond. Oil spots are treated separately because sealer will not stick to them, cracks are sealed and repairs done at this stage, kerbs and drains are masked, and then the coating goes down.
- 04
Cure, restripe, walk it
The section stays closed until it has cured, and how long that takes depends on the conditions that day. Then the layout is repainted, because sealcoat covers the old markings, and we walk the finished lot with you rather than sending an invoice and disappearing.
The two questions that decide the job
Driving on it, and working around your tenants
Every property manager asks these two, usually in this order, and they matter more than anything else on this page.
On cure time, we will not publish a figure. Sealer cures by evaporation, so surface temperature, sun, humidity and airflow all change the answer, and a number that is right on a hot dry afternoon is wrong on a cool damp morning. What we will do is tell you the window for your lot and the conditions we are actually working in, in writing, before we start.
On scheduling, the lot is staged in sections so part of it stays open while another cures, and crews work nights and weekends so the closed section is closed when fewest people need it. That is the whole reason night work exists in this trade. It is not a premium service, it is how you sealcoat an occupied property without shutting it.
- Cure window given for your lot and your conditions, in writing, before the first day
- Lot staged in sections so you never lose all your parking at once
- Nights and weekends so the closed section is closed at the quietest time
- A call if the weather moves the schedule, rather than a crew that does not turn up
Timing
There is a season, and it is set by conditions rather than the calendar
Sealer needs the surface warm enough to cure properly and dry enough to bond. Both of those are weather, not dates, which is why the honest answer to when you should sealcoat is a range of conditions rather than a month.
In practice Central Texas has a real working window, and there are periods when the right advice is to wait rather than to take your money and coat a surface that will not cure. Ask us about the period you are planning for and we will tell you what the window looks like, including when the answer is not yet.
This is worth planning around rather than reacting to. A lot that is scheduled in advance gets done in good conditions; a lot that becomes urgent in the wrong month gets done badly or gets postponed anyway.
Questions
What property managers ask about sealcoating
How long before we can drive on it?
It depends on the weather that day rather than on a fixed number. Sealer cures by evaporation, so surface temperature, sun, humidity and airflow all move it, and a cool damp morning behaves differently from a hot dry afternoon. We will tell you the window for your lot and the conditions we are working in, in writing, before the first day. Anyone quoting you a flat figure without knowing the forecast is guessing.
Do you have to close the whole lot at once?
No. The lot is staged in sections so part of it stays open while another part cures, and crews work nights and weekends so the closed section is closed when the fewest people need it. On most commercial properties that is the difference between a scheduling inconvenience and a closure.
How often does sealcoat need redoing?
It depends on how much traffic the lot takes, how much direct sun it gets, and how well it drains. A shaded, lightly used lot and a west-facing retail lot that fills every day will not wear at the same rate. We would rather walk your lot and tell you what we actually see than publish a number that will be wrong for half the properties that read it.
Will sealcoating fix the cracks in my lot?
No. Sealcoat is a surface coating, not a filler, and applying it over open cracks hides them for a few weeks and then they come back through. Cracks are sealed as separate work before the sealcoat goes down, which is why crack sealing is normally quoted alongside it rather than after it.
What about potholes and broken pavement?
Those are asphalt repair, and they need doing first. Sealcoat is roughly the thickness of paint. It cannot bridge a hole, it cannot re-bind pavement that has already come apart, and it will not do anything for a base that has failed underneath. If we walk your lot and find that, we will tell you plainly rather than coat over it.
Do the parking lines have to be repainted afterwards?
Yes. Sealcoat covers the existing markings, so restriping is part of the job rather than an extra to decide on later. It is also the practical moment to correct a layout, add accessible spaces or fix fire lane markings, because the lot is already blank and the crew is already there.
Is there a time of year you cannot sealcoat?
Yes. Sealer needs the surface warm enough to cure and dry enough to bond, so the working window is set by temperature and moisture rather than by the calendar, and rain in the wrong place ruins a fresh coat. That gives Central Texas a real season. Ask us what the window looks like for the period you are planning and we will tell you straight, including when the answer is to wait.
What should I tell my tenants before you come?
Which sections are closed and when, that the closed area needs to be empty of vehicles, and that there will be a smell during application that clears. We give you the section plan and the schedule in writing before the first day so you can send it on without having to translate it.
