Frequently Asked Questions

What's the difference between RejuvaSeal Penetrating Asphalt Rejuvenate and Sealcoat? 

The primary difference between RejuvaSeal and Asphalt Emulsion (Sealcoat) is the most important one, Emulsion sealers do not penetrate the asphalt. Another difference is that the Sealcoat is an emulsion in a water suspension while RejuvaSeal is a complex hydrocarbon mixture that contains no water. The primary difference is important to note because emulsion seals only protect the surfaces of the asphalt binder while RejuvaSeal penetrates, rejuvenates, and replenishes the natural oils lost through the oxidation process

Does RejuvaSeal contain Gilsonite? 

No. RejuvaSeal is a complex hydrocarbon mixture of asphalt oils and solvents.

How Does RejuvaSeal compare with other asphalt rejuvenators?

While all asphalt rejuvenators have the same basic design mix, the difference with RejuvaSeal is that we use the highest grades of raw stock materials using double distilled rejuvenation oils for the highest quality available. Many asphalt rejuvenator manufacturers use the cheapest materials to meet specifications. We do not.

How long does RejuvaSeal extend the life of my asphalt? 

The average life-extension of your asphalt is 3-5 years. If RejuvaSeal is applied within the first 12 to 18 months after installation and every 3-4 years thereafter, as recommended, it could extend the asphalt life indefinitely.

How often should RejuvaSeal be applied? 

RejuvaSeal should be reapplied every 3-4 years after the first application or when needed. Weather factors, as well as seasonal temperatures, are a factor in when RejuvaSeal should be readministered.

Should crack sealing be done before or after RejuvaSeal is applied? 

We recommend using a crack sealer after RejuvaSeal is applied. The prep work, such as removing vegetation, routing, and cleaning the cracks should be done before RejuvaSeal is administered. This allows RejuvaSeal to create a clear and fresh bonding surface for the crack seal to do its work as well as rejuvenate the walls of the cracks.

What is the prep work that should be done before applying RejuvaSeal? 

Any dust, dirt, debris, vegetation, and moisture must be removed from the asphalt binder. The lot can then be washed with high-pressure water and then leave it to dry for 24 hours. We do recommend high-pressure air rather than water due to the damage water can do to asphalt.

Before applying RejuvaSeal, what does the ground temperature have to be? 

The ambient surface temperature of the asphalt must be at least 50 degrees Fahrenheit and rising. Best way to check is with an infrared temperature gun in multiple locations before applying RejuvaSeal.

How long does RejuvaSeal take to dry? 

The time it takes for the asphalt rejuvenator to dry depends on a number of factors including ambient surface temperature, the temperature of the air, the humidity, and the application rate. The range can be from 4-24 hours depending on these factors. Once the RejuvaSeal is applied, a minimum of 24 hours is recommended before allowing traffic on the surface.

Can the lot be painted directly after applying RejuvaSeal? 

No, the asphalt rejuvenator needs time to dry before applying paint to the surface. We recommend a minimum of 24 hours.

When is the best time to apply RejuvaSeal? 

The ideal time to use RejuvaSeal is at the 1-4 year point, the sooner our asphalt rejuvenator is applied to your asphalt the sooner it can be preserved. This further protects your lot from weathering and oxidation.

What is the application rate of RejuvaSeal? 

RejuvaSeal is administered in one application and varies from .05 gallons per SY to .085 gallons per SY, depending on the asphalt.

Is there anytime RejuvaSeal shouldn't be applied to my asphalt? 

If your asphalt is less than 6 months old then RejuvaSeal shouldn't be applied. It is best for your asphalt to be at least 1-year old before administering the rejuvenator. As RejuvaSeal is designed to reintroduce the natural oils back into the asphalt binder, if the asphalt is fresh you run the risk of saturating the lot.

Also, if the asphalt is too far gone for any kind of treatment to bring it back, RejuvaSeal will improve the appearance of the lot while not necessarily providing any rejuvenation benefits.
