Sealcoating

Sealcoating 1

Sealcoating, or pavement sealing, is one of the best methods of protecting your asphalt. A protective layer of sealant is applied to the pavement surface. This application protects it from water, oils, sun damage, and chemical penetration.

There are several types of standard sealers: refined tar-based, asphalt-based, and petroleum-based. Each sealer has its advantages and disadvantages, and timelines.

Sealers

A refined tar-based sealer provides the best protection against water and other chemicals. It lasts about 3-5 years. Asphalt and petroleum-based sealers are less effective at protecting against water and chemical damage and have a shorter lifespan of approximately 1-3 years. At Pavecon, we generally recommend sealcoating every 2-3 years; however, this could depend on the wear of the sealer.

If you have a surface that needs protection from the elements, Pavecon delivers only the best sealcoating services.

 

Sealcoating FAQs

N/A

N/A

Does Pavecon provide sealcoating for all asphalt surfaces?

Yes, Pavecon provides sealcoating for any paved, asphalt surface (such as parking lots and roadways), providing the surface is in a good enough condition to receive sealcoat. Pavecon will inspect the area and make a recommendation.

How long does it take sealcoating to cure before commercial vehicles can drive on it?

Sealcoat cure time depends on air temperature and humidity. In areas where it’s warm and less humid, sealcoating can be applied and used the same day. However, a good rule of thumb for optimum performance is 24 hours after application.

What type of conditions or time of year is ideal for sealcoating?

Sealcoat application requires an ambient temperature above 50°F to cure properly. Accordingly, sealcoat is typically applied during the warmer months.

Does Pavecon use water or oil-based sealcoating?

Pavecon uses an emulsified asphalt water-based sealcoat.

How long does it take Pavecon to sealcoat an average parking lot?

For larger parking lots such as grocery stores and retail shopping centers, it may take 4-5 days to do the entire parking lot. Bigger lots such as distribution centers can take longer. Applications are typically performed in sections that be completed in 1-2 days. Individual sections are completed on a rolling process to maintain business traffic throughout the sealcoating process. Once completed the surface should be allowed to cure for 24 hours before opening to traffic. Smaller lots can be completed in as little as one day.

How often should I be sealcoating our asphalt?

Sealcoating should be inspected annually and touched up or repaired if necessary. Typically, sealcoating will last 3-5 years. In high-traffic areas or areas experiencing heavy-duty loads, more frequent applications may be recommended.

I’m not completely convinced sealcoating is worth it - what happens if I don’t do it?

Sealcoating is designed to preserve the integrity and appearance of your asphalt investment. It protects the asphalt from fuel and oil spills, UV light damage, moisture penetration, and surface wear. Unsealed asphalt pavement is vulnerable to surface deterioration, cracking, aggregate loss, and potholes. Sealcoating extends the life of your pavement and preserves the value of your pavement assets.

At what point should pavement be completely replaced instead of sealcoated? Can Pavecon help with this?

It may be too late to sealcoat if the surface of the asphalt is severely cracked, has large potholes, or other significant failures. Our team can help assess the overall condition of your parking lot and make recommendations.

Do I need to be concerned about rain or other precipitation hurting sealcoating?

When applied properly and under ideal conditions, sealcoat will be dry and impervious to rain within 12 hours after application. Rain immediately following application can extend curing time.
