Sealcoat

Sealcoat Overview

Sealcoat is applied to asphalt to seal the pavement surface and protect it from the degradation caused by sunlight, oxidation, and water, and to act as a shield against drippings such as oil and gasoline. Sealcoat also beautifies the pavement by providing a smooth, black, even surface ideal for painting lines and sweeping. On older pavements, sealcoating can replace fine particles lost from the asphalt surface while sealing small cracks before they become larger, protecting the supporting base material from water intrusion. While sealcoats have historically been designed for off-highway use where there are low traffic speeds, newer, more complex blends are being used on roads, highways, and runways.


Sealcoating Contractors – CPM

California Pavement Maintenance Company installs both SteelGuard™ and OverKote™, two of the premiere asphalt sealcoats on the market. SteelGuard™ uses cutting-edge technology to assure longer-lasting protection and improved hot and cold weather performance. SteelGuard is available in a variety of mixes that are designed for different weather and traffic conditions. CPM can also design custom mixes specifically tailored for the needs of your roadways, runways, or parking lots.

Sealcoat Advantage

Low Cost

Sealcoat costs pennies per square foot compared to the dollars needed to repair or replace damaged asphalt. Sealcoat is also less expensive than heavier slurry seal and micro surfacing treatments.

Beautification

Sealcoat can put a smile on your pavement by providing a smoother, blacker, a more even surface that gives a good impression to prospective tenants, home buyers, customers, and the general public.

Preservation

When used as part of a preventive maintenance plan, sealcoating dramatically extends the life of asphalt pavement – saving you money over the long-term.

Sealcoats typically last between 3-5 years, depending on the quality of the material used and the millage (thickness) of the actual application.  Sealcoats have a shorter life span than heavier-duty treatments like slurry seal and micro surfacing, but they are also less expensive.

What Is Sealcoat?

Sealcoat is generally a mixture of emulsified asphalt, water, mineral fillers, and various other components. Premium grade sealcoat materials like SteelGuard™ and OverKote™ use select, highly stable asphalt binders with cross-linking chemistry and premium, crushed-graded aggregate particles.

Applying Sealcoat

Sealcoats are applied by rubber squeegee, broom, or mechanical spray. Many pavement engineers recommend a two coat application using a squeegee application on the first coat and a spray application on the second. This allows the mechanical down pressure of a squeegee to fill cracks, displace dust particles and to insure adherence while the second spray coat provides an even filling of voids and a smooth, uniform finish.
