Why is Asphalt Sealcoating Necessary
Asphalt is a black, plastic-like material that holds aggregate particles together. Asphalt binds the sand, crushed stone and gravel particles together and sealcoating helps preserve your asphalt pavement against heavy traffic, UV rays, grease, snow and other chemicals and natural elements that causes the material prematurely deteriorate.
If you want your driveway to last, sealcoating it is the best way forward as unprotected asphalt is more vulnerable to cracks and potholes that can eventually severely damage your pavement’s foundation. Sealcoating is necessary to protect your property and prolong its lifespan. A sealcoating can significantly improve the appearance of your driveway and is considered a cost-effective investment in the long-term.

Types of Sealcoating
There are two main types of seal coat products, coal tar and asphalt emulsions. Coal tar is less expensive but requires more frequent reapplication. It is more often applied by professional crews. When asphalt sealcoating, it is important to consider the environmental footprint. Asphalt emulsion sealers emit fewer VOCs than regular coal-tar based materials and do not rely on petroleum byproducts that fuel chemical spills. However, this type of sealer provides less protection against overflows with fluid fuels or chemicals.
Two other kinds of asphalt sealers are acrylic and fast-dry. Acrylic sealers are synthetic compounds comprised mostly of acrylic and polymers, while fast-dry sealers allow water to penetrate the surface quickly. Acrylic sealer is less harmful to the environment and poses fewer health risks than other types of sealers. But more-expensive materials may not offer as good of a protective layer. Fast-dry sealers are usable for foot traffic about an hour after application, and for vehicle traffic in a single day.
This is a good option when the East Georgia Asphalt Paving contractors needs to quickly return the driveway or parking lot to service. But fast-dry options do not last as long, and it requires temperatures above 75 degrees Fahrenheit for application.
How Often to Sealcoat?
The seal coating process is typically first applied one year after the underlying asphalt has been set to permit legitimate fix and wear of the surface. After this, it’s suggested that you have carports and parking areas seal covered each a few years for ordinary use, or consistently if the asphalt encounters hefty traffic.
Benefits of Sealcoating
Seal coating has distinct benefits as preventive maintenance for asphalt paving:
- Asphalt sealcoating extends the life of a driveway or parking lot by preventing asphalt from hardening and crumbling.
- Creates a uniform coat over pavement, making it less susceptible to cracks and holes
- Prevents salt, chemicals, or moisture from entering asphalt
- Sealcoating is cheap, easy to apply, and many homeowners or small businesses are capable of applying it themselves rather than hiring a firm.
- Sealcoating is a cost-effective way of fixing any damaged or weathered pavement, extending its life and improving the look.
The Asphalt Sealcoating Process
Professional seal coating crews or individual homeowners or businesses follow this general procedure for seal coating:
- Check the climate estimate and select a period when dry climate is normal for something like 48 hours.
2. Ensure that there is no traffic in the process of doing asphalt sealcoating by barricading the driveway or parking lot.
3. Run a general cleaning with a broom and power washing.
4. Apply liquid sealer to deep scratches first, then apply a thin coat of oil spot prime over these areas.
5. Patch holes with asphalt patching compound to create a smooth surface.
6. Applying a liquid seal coat with an appropriate squeegee or sprayer.
7. Check for spots missed, and plan for a second coat for the following day.
8. Remove barricades after the asphalt seal coat has dried, generally about 36 hours.
9. Parking spaces must be striped before the surface has cured for at least 24 hours.
After the installation, East Georgia Asphalt Paving contractors will apply another layer of protection on the surface to safeguard it from rain and precipitation for at least 24 hours. The curing of sealcoating is generally a time-dependent process.
The right time of the year to sealcoat is when temperatures are expected to drop no lower than 55 degrees, which will ensure that the product cures properly. Watch for leaves and debris that might degrade the emulsion coating once it has been applied and before it has set.
Once asphalt has been installed, it gradually begins to deteriorate. Oxidation, moisture penetration, gas and oil spills, along with the effects of ultraviolet rays all contribute to the eventual deterioration of the asphalt.
This is why we at, East Georgia Asphalt Paving, highly recommend asphalt sealcoating to all types of asphalt-based pavements. With correct and consistent application of coal tar sealer on the surface, it will prevent any further damage, and dramatically increase the life and curb appeal of your asphalt driveway and parking lot.
