Rejuvenator/Sealer

The Most Commonly Asked Questions…

What is Rejuvenator/Sealer?
The product is a blend of coal-tar, coal-tar oils and maltenous type rejuvenating agents. It is designed to penetrate into the asphalt surface, to chemically improve the asphalt pavement. It is not a "water based" sealcoat that only coats the surface and cannot improve the pavement. Rejuvenator/Sealer has gained rapid acceptance in the industry, but beware cheap imitations that are now on the market. A high quality Rejuvenator/Sealer must meet all of its own "ASTM" performance tests, and have "FAA" Engineering Brief 44-A certification.

How does Rejuvenator/Sealer work?
Oxidation of the asphalt binder causes the pavement to become hard and brittle. Rejuvenators reverse oxidative hardening (the aging process of asphalt), replace essential oils lost through oxidation, and stop raveling (the loss of small stones in the pavement).

How is Rejuvenator/Sealer applied?
The Rejuvenator is applied with state-of-the-art high volume equipment utilizing computer-controlled flow rate nozzles for a uniform, one-step application that minimizes downtime. When should Rejuvenator/Sealer be applied? The Rejuvenator may be applied to all types of asphalt during the life of the pavement; results will vary with age. On newer pavements treatments every 3 to 5 years will considerably extend the life of the pavement. It should not be applied over a sealcoat or coating until the coating has been significantly worn off, as they will inhibit the penetration of the Rejuvenator.

How much does Rejuvenator/Sealer cost?
The bottom line, Rejuvenator is competitive in price to a sealcoat, if the sealcoat is not "watered down" or applied too thin. Rejuvenator will cost about one to two cents a square foot more then a quality sealcoat. However, on the average a sealcoat needs to be applied every 2 to 3 years. The Rejuvenator needs be applied every 3 to 5 years, providing a 25% cost savings.
