The Different types of sealcoat:

The main types and the pros and cons of each

There are several types of sealcoat available in the pavement maintenance industry. Each one is made with a different base along with additives. Each unique mix has different pros and cons from the durability, drying color, protection against elements, and cost from the manufacturer. Here at Omega, we want you, the consumer, to be educated on the various types of sealcoat so you know the questions to ask your asphalt maintenance company, even if you decide not to go with us.

Refined Coal Tar Sealer

Made from coal tar, water, sand, and other additives, coal tar sealcoat is a popular and cost-effective option for pavement protection.

Pros:

Durability: Coal tar sealcoat provides excellent protection against UV rays, water, and chemicals. It is also resistant to gasoline and oil, making it ideal for areas with high traffic.
Cost-effective: Coal tar sealcoat is one of the most affordable options for pavement protection, making it a popular choice for homeowners and businesses on a budget.
Easy to apply: Coal tar sealcoat is easy to apply, making it a popular DIY option for homeowners. However, we recommend that you consult with a professional pavement contractor to ensure proper application.

Cons:

Environmental concerns: Coal tar sealcoat contains polycyclic aromatic hydrocarbons (PAHs) which are harmful to the environment and human health. The application of coal tar sealcoat can also release volatile organic compounds (VOCs) into the air.
Long-term health risks: Prolonged exposure to coal tar sealcoat can cause respiratory problems, skin irritation, and other health issues.
Discoloration: Coal tar sealcoat can fade or discolor over time, giving your pavement an unsightly appearance.

Asphalt EMULSION SEALER

Made from asphalt and water, asphalt emulsion sealcoat is an eco-friendly option that is safer for the environment and produces fewer volatile organic compounds (VOCs).

Pros:

Environmentally friendly: Asphalt emulsion sealer produces fewer volatile organic compounds (VOCs) than coal tar sealcoat, making it a more eco-friendly option. It is also safer for human health and the environment.
Cost-effective: Asphalt emulsion sealer is a cost-effective option for pavement protection, particularly for those on a budget.
Easy to apply: Asphalt emulsion sealer is easy to apply, making it a popular DIY option for homeowners. However, we recommend consulting with a professional pavement contractor to ensure proper application.

Cons:

Durability: Asphalt emulsion sealer is not as durable as coal tar sealcoat and may require more frequent applications to maintain its effectiveness.
Limited resistance to oil and gasoline: Asphalt emulsion sealer is less resistant to oil and gasoline than coal tar sealcoat, making it less suitable for areas with high traffic.
Limited longevity: Asphalt emulsion sealer typically lasts between 1 to 3 years, which is less than some other sealcoat options.

PETROLUEM Sealer

Made from refined crude oil, petroleum-based sealcoat provides excellent resistance to oil and gasoline and can last up to 5 years.

Pros:

Durability and Environment Friendly: Best of both worlds. Petroleum based sealer can provide a similar level of protection as coal tar sealers and the low VOC levels of asphalt emulsion sealers.
Excellent Resistance: Superior resistance to oil, gasoline, and UV rays when compared to Asphalt Emulsion.
Long Lasting: Can typically last 3-4 years depending upon the conditions of the environment.

Cons:

Expensive: Often on the costlier side per square foot due to the high cost to manufacture.

WHICH TYPE OF SEALCOAT IS THE BEST?

The best type of sealcoat for sealing asphalt depends on several factors, including the climate, the condition of the asphalt, and the intended use of the pavement. Ultimately, the best type of sealcoat for sealing asphalt will depend on the specific needs and priorities of the project.
