Comparing Sealcoating Materials: What Works Best for Michigan Asphalt
Sealcoating is not a “nice-to-have” in Michigan. It’s basic asset protection. Between freeze-thaw cycles, snow, ice, road salt, summer heat, and constant traffic, asphalt here takes a beating. Choosing the right sealcoating material is what separates pavement that lasts from pavement that fails early.
At Asphalt Express LLC, we provide professional seal coating maintenance for commercial parking lots and driveways across Oakland, Livingston, Wayne, and Macomb Counties. Below is a straight-talk comparison of sealcoating materials—and what actually works for Michigan asphalt.
What Sealcoating Does for Your Asphalt
Before comparing materials, let’s level-set on why sealcoating matters.
A properly applied sealcoat protects asphalt from:
Water penetration and freeze-thaw damage
UV exposure and oxidation
Oil, fuel, salt, and chemical spills
Traffic wear and surface abrasion
Sealcoating slows deterioration, helps prevent cracking and potholes, improves appearance, and extends the overall life of your pavement. It’s a key part of long-term commercial parking lot maintenance, not a cosmetic shortcut.
For a deeper breakdown, see our guide on the benefits of sealcoating for Michigan asphalt.
Types of Sealcoating Materials
Not all sealcoats are created equal. The right choice depends on traffic levels, surface condition, and Michigan’s climate realities.
Asphalt Emulsion Sealers
Best for: Most commercial parking lots and standard asphalt surfaces.
Asphalt emulsion sealers are water-based products made from refined asphalt and additives. They are the most commonly used option today and the go-to choice for professional Michigan asphalt seal coating.
They bond well to existing pavement, remain flexible during temperature swings, and provide reliable protection against moisture and oxidation.
Pros:
Cost-effective and environmentally compliant
Flexible during freeze-thaw cycles
Strong all-around protection for most lots
Cons:
Less resistant to harsh chemicals than specialty blends
For many properties, asphalt emulsion sealers paired with routine inspections offer the best value. Learn more in our commercial parking lot maintenance checklist.
Polymer-Modified Sealants
Best for: High-traffic commercial parking lots and heavy-use areas.
Polymer-modified sealants build on asphalt emulsions by adding polymers that improve flexibility, adhesion, and durability. These are ideal for lots with frequent vehicle turnover or heavier traffic loads.
In Michigan, polymer-modified sealants hold up better against seasonal movement and surface stress.
Pros:
Longer lifespan than standard emulsions
Improved resistance to traffic and weather
Better performance in demanding conditions
Cons:
Higher upfront cost
If your lot sees consistent wear, this option often delivers a stronger return on investment. Pairing this with resurfacing when needed can significantly extend pavement life. See why timely parking lot resurfacing saves money.
Coal Tar Sealers (Rarely Recommended)
Coal tar sealers were once popular due to chemical resistance. Today, they are heavily restricted or avoided due to environmental and regulatory concerns.
In Michigan, asphalt-based alternatives are typically preferred and more widely compliant.
Pros:
Strong chemical resistance (historically)
Cons:
Environmental concerns
Regulatory limitations
Not commonly recommended for modern projects
Most property owners are better served by asphalt emulsion or polymer-modified systems.
Choosing the Right Sealcoating Material for Michigan
For Michigan asphalt, the best sealcoating strategy balances durability, flexibility, and compliance:
Asphalt emulsion sealers work well for most commercial parking lots
Polymer-modified sealants are ideal for high-traffic or heavy-use areas
Material choice matters—but surface preparation matters more
Crack filling, cleaning, weather timing, and professional application determine how long a sealcoat actually lasts. Poor prep shortens performance, no matter the product.
