Sealcoating is the single most important step that can be taken to preserve your residential and commercial asphalt pavement and walkway, because it adds an extra layer of protection from harmful elements to your asphalt surface. UV rays, snow, oil, and chemicals can all be harmful to your asphalt pavement. These elements will gradually penetrate the surface and destroy its foundation if it is not protected.
Our sealer can be tailored to any stage of your pavement’s development. BRO Sealcoating and Asphalt Maintenance use Neyra AE at (Asphalt Emulsion). This is an environmentally friendly asphalt emulsion made up of high molecular weight polymers, mineral fillers, and specialized surfactants that is designed as a weather-resistant, water-resistant coating for asphalt surfaces.
Sealcoating is an important component of a pavement management plan because it:
- Improves the aesthetic value of a home or property.- A fresh sealcoat gives the pavement a dark black color, making it look and wear like new. A black parking lot has a clean, rich appearance that promotes the company, facility, or residential complex.
- Slows oxidation and water penetration – Oxygen exposure hardens asphalt binders, resulting in a brittle pavement surface that cracks quickly. Water can penetrate the sub base through these cracks, weakening it and reducing pavement strength. This, in turn, causes more cracks, which can eventually grow to become potholes. Sealcoats fill surface voids, reducing oxygen and water exposure and extending pavement life.
- Resists gas and oil spills – Engine oil or gasoline can soften asphalt. Asphalt emulsion sealers prevent this damage because asphalt emulsions are not soluble in gas or oil. Asphalt emulsion sealer manufacturers typically add polymers to increase resistance to gas or oil. Sealing reduces the depth to which oil or gas can penetrate by filling surface voids.
- Resists ultraviolet rays – The sun’s ultraviolet rays break the links between carbon bonds in asphalt. Sealcoat does not repair existing asphalt damage, but it does prevent ultraviolet rays from further damaging the asphalt pavement.
- Cost-effective in the long run – Sealcoating a parking lot every couple of years with a coal tar or asphalt emulsion is less expensive than overlaying or placing it.

What are the signs that I should sealcoat my driveway and parking lot?
Asphalt is composed of 95% aggregates and 5% oil, Tar, and bitumen that binds them together. When aggregates become exposed, look greyed, faded, and oxidized, it clearly indicates that asphalt needs to be sealcoated, because the asphalt ingredient that binds them together and maintains flexibility has dried out.
How often should I sealcoat my asphalt driveway?
Because of the nature of asphalt ingredients, it is usually recommended that you seal your driveway and parking lot every two to three years to prevent oxidation, loss of flexibility, cracking, and crumbling.
What should you expect after Sealcoating?
We recommend staying away from freshly sealcoated asphalt for at least 24-48 hours to allow it to cure. Here are a few things to keep in mind:
- Tire marks – When your property has been sealcoated with Asphalt Emulssion, it is common to see tire marks or scuffs. This could be due to the following severe factors:
- Large vehicles or trailers
- Extremely high temperatures or humidity
- Power steering (turning in a tight space) or changing tire direction while the vehicle is stationary
These marks are all temporary and will fade over time. You can reduce the visibility of these marks by staying away from the sealcoat for as long as possible.
- Sealcoat on grass – while we do our best to keep the grass away from the asphalt, if any grass is stained with sealcoat, it will fade over time.
