The advantages of using PolyCote® Premium Grade Pavement Sealer, Manufactured By, The Brewer Company.


You may ask:
What is a premium grade pavement sealer system, isn’t sealcoating just sealcoating?

What Is Traditional Pavement Sealer Compared To A Premium Grade Pavement Sealer:

When coal tar emulsion is purchased from a pavement sealer manufacturer or authorized distributor, it comes in a concentrated form resembling pudding. The manufacturer then suggests certain mix designs each contractor should follow.
Most manufacturers suggest a dilution ratio of 25-35 gallons of water per 100 gallons of concentrate. In addition, a latex modifier (Also called an additive) is recommended at a rate of 1-5 gallons per 100 gallons of concentrate. Silica Sand or Black Beauty Slag is also recommended to be added at a rate of 100 lbs. to 500 lbs. per 100 gallons.
In theory, when the sealcoating contractor is finished blending all the ingredients together; you will have a mix design which meets the manufacturers specification, this, coupled with the proper application method, should give you a pavement sealer application that lasts 2-3 years, depending on your geographical location.
However, very few contractors mix and apply the coal tar emulsion pavement sealer to meet or exceed the manufacturer’s specifications.
Our parking lot consultants are trained to help property managers identify these inferior applications. We do this by encouraging them to contact the manufacturer or certain cooperative distributors to ascertain how the bidding contractor mixes their pavement sealer. They find, 7 times out of 10, the contractor is mixing the concentrate sealer with only water. To add insult to injury, water dilution ratios far exceed what the manufacturer’s recommendations!
By using a premium grade pavement sealer, such as PolyCote®, you are guaranteed to receive a long lasting application; in fact, PolyCote® has been “PROVEN” to be the longest lasting coal tar emulsion pavement sealer available on the market!

What defines a “Premium Grade Sealer?”
• Better controlled solids content (Meaning less water in the coating base during manufacturing). Manufacturer delivers the product to approved applicators in bulk, ready to use, no additional water dilution is permitted! Contractors then only have to mix the required amount of sand from 2-3 lbs. per gallon.
• High weight molecular polymer (Latex) is hot-blended into the coating base during the manufacturing process. By hot-blending the polymer during manufacturing versus the standard practice of post-mixing it on the job site, the polymer is fused to the base of the coating thereby strengthening it and providing the longest lasting pavement coating on the market.
• Made with 100% Refined RT-12 (No asphalt emulsions mixed into the coating- a true 100% coal tar sealer)
• Manufactured in a colloid mill process, not a batch process. It is documented and recognized by industry experts that pavement coatings manufactured with a mill process are better refined and longer lasting than a batch mixing process.

Benefits to the Property / Facility Manager or Property Owner:

• QUALITY CONTROL: By the manufacturer controlling the mix design, the end user is GUARANTEED to receive the highest quality application in the industry. Most sealcoating contractors applying a premium grade pavement sealer will warranty the coating for a year, if at all. If applied to sound pavement in a two coat application, Jet-Seal warranties their two coat process, three coats in high traffic areas, with a two year warranty. Fair enough?
• Better wear resistance and stronger adhesion with up to twice the durability of conventional pavement sealers.
• Extends the life expectancy of your pavement coating system- Standard pavement sealers require re-coating after 2-3 years. Poly Tar can last 3-4 years with proper applications. Minimize impact to you and your tenants business by extending the dreaded parking lot closing or phasing from every 2-3 years out to every 3-4 years.

Life Cycle Benefits of Maintaining Pavements
FEB 1, 2016

The benefits of sealcoating asphalt parking lots are measured in the long term through increased useful life of the pavement resulting in reduced cost. There are other potential benefits that can best be seen through the long term, such as impacts on energy usage or environmental impacts. Life cycle analysis is a method of comparing benefits of using different methods or materials. Two life cycle analysis studies have highlighted the benefits of pavement maintenance.
The first study was presented at the First International Conference on Pavement Preservation held in 2010 in Newport Beach. One of the papers presented at this conference, Energy Usage and Greenhouse Gas Emissions of Pavement Preservation Processes for Asphalt Concrete Pavements by J. Chehovits & L. Galehouse, looked at roadway pavements with a focus on energy use and greenhouse gas (GHG) emissions of new and major repaving projects versus energy use and GHG emissions of pavement maintenance operations. The goal of pavement maintenance programs is the same for roadways and parking lots. The Chehovits & Galehouse paper describes the rationale for pavement maintenance this way:
"Use of pavement preservation treatments extends the remaining service life of asphalt concrete pavements. These treatments typically include spray applied surface seals, thin overlays, crack treatments, chip seals, slurry seal/micro surfacing, surface recycling and others. Each preservation treatment reduces damaging effects of aging and deterioration of the pavement surface layer and helps protect the integrity of the underlying pavement structure. If proactive preservation treatments are not used, pavements deteriorate more rapidly and require major rehabilitation with structural overlays or reconstruction much earlier."
The study found that significant energy and GHG emissions savings are achieved when using pavement preservation techniques. Their findings concerning energy savings were summarized as follows:
"New construction, major rehabilitation, thin HMA overlay, and HIR have the highest energy use and range from 5,000 to 10,000 BTU/yd2 per year. Chip seals, slurry seals, micro-surfacing, and crack filling utilize lower amounts of energy per year of extended pavement life and range from 1,000 to 2,500 BTU/yd2 per year. Crack seals and fog seals use the least amount of energy per year of extended pavement life at less than 1,000 BTU/yd2 per year."
The overall conclusion of the study was:
"To minimize energy use and GHG emissions over the life of a pavement, all preservation treatments should be utilized as appropriate to the maximum extent possible for the existing pavement conditions."
The second study was by D. Schechtman as part of the New York-New Jersey Harbor Study conducted by the New York Academy of Sciences. Schechtman conducted a limited life cycle analysis (LCA). Schechtman described his work as follows:
"…we have conducted a comparison of the upstream environmental impacts of refined coal-tar sealed, asphalt sealed, and unsealed concrete parking lots. This analysis is limited to estimating the “upstream” environmental impacts – only those associated with the manufacturing, and installation of parking lots."
One conclusion of the LCA was as follows:
"In assessing which lot has the lowest overall environmental impact in the upstream phase (manufacturing and installation), the result will depend on which indicator you value the most. If toxic emissions … were of the greatest concern then the asphalt lot, specifically the asphalt lot sealed with refined coal-tar based sealant, would be the best option for the upstream phase. [emphasis added]"
The difference between coal tar and asphalt-based sealants were much smaller than the difference between those two and a concrete paved surface.

Things Sealcoating Doesn’t Do

Trust in an asphalt contractor is essential. We want all of our customers to have a positive experience and having realistic expectations is paramount. Many of our first time customers don’t fully understand the capabilities of sealcoating.  Most asphalt maintenance companies express in great detail the benefits of sealcoating asphalt driveways. The benefits are outlined throughout our website and social media as well. In a nutshell, sealcoating is a preventative maintenance procedure that will extend the life span of your asphalt driveway as well as add to the curb appeal of your property. What most asphalt maintenance companies fail to disclose is the things sealcoating doesn’t do. I must confess that until now Jet-Seal has been guilty of the same practices. We are continually trying to improve our customer experience and routinely have group discussions about things we can do to make every experience with Jet-Seal a positive one. The topic most discussed is the best way to educate our customers about our company, our products, our application methods and how we can separate ourselves from the competition. 
Many of our competitors are honest and have just assumed that homeowners are aware of the process including the benefits as well as the limitations of the service. Some are not so honest and deliberately mislead, even making claims that are outright lies in an attempt to take advantage of you.
Many of our customers are first time homeowners. Many are first time owners of a home with an asphalt driveway, having had concrete or other types of driveways in the past.  So, for those of you who are not experts in asphalt maintenance we have made a list of some of the limitations of sealcoating.
• Sealcoating will not improve structural deficiencies.
• Sealcoating will not fix damaged or defective pavement.
• Sealcoating will not level depressions or uneven pavement.
• Sealcoating will not fill or hide cracks. We offer a separate product for crack sealing. Please see our page on crack sealing to learn more about the benefits and limitations of crack sealing.
So keep this in mind; if your neighbor’s driveway is relatively new and well-constructed and yours is 10 or 15 years old, the driveways are not going to look the same after sealcoating.  
If you have any additional questions please don’t hesitate to contact us. We are always happy to answer your questions. 

Asphalt Crack Sealing 101

This article will help you understand the crack sealing process. A well informed customer tends to be a happy customer. We at Jet-Seal want to do all we can to help make your expectations realistic.
Asphalt maintenance is a comprehensive program consisting of among other things, crack sealing. Jet-Seal uses different asphalt crack sealing products for different applications. For commercial asphalt parking lots we use a hot rubber sealant. This product is the most effective product but there are downsides to using it for residential driveways. Besides the possibility of tracking the biggest reason we hesitate to use a hot rubber sealant is appearance. While even our alternative cold pour product (no heating required) has a contrast to our sealcoat the hot rubber product has a more definitive contrast.  Jet-Seal uses Brewer Everlastic , a dark blend of acrylic co-polymers and reinforcing fillers specifically designed to outperform traditional based crack fillers. Everlastic is fast drying, exhibits minimal shrinkage and remains flexible over a broad temperature range. It can be used to seal cracks up to ½” in width. It quite simply is the best cold pour product on the market.
Crack sealing prevents water from entering the base of the driveway causing structural damage that leads to potholes. Depending on the amount and type of cracks it can be a cost effective way to prolong the life of the asphalt driveway. If a driveway has an excessive amount of cracks it is not cost effective to perform the service. If the cost of the service exceeds the benefits we will tell you. If the cracks are structural in nature we will let you know and advise you on the most cost effective approach to take.
One of the most important things to understand about crack sealing is that the service is an ongoing maintenance item. Once a crack forms it is not a matter of if it will open back up but a matter of when.  The freeze/thaw cycle here in central Ohio is the main culprit of crack seal failure but there are other causes. Water seeping up from the stone base to the surface of the driveway will cause adhesion problems.  A ½” crack on the surface could be much wider at the base of the driveway causing the sealant to fail sooner than expected. If this is obvious at the time of the service we will fill the crack with sand before applying the crack sealant. This can sometimes cause a difference in texture and highlight the contrast between the crack sealant and the sealcoat. 
Because it is impossible to determine the severity of the crack from its appearance on the surface of the driveway along with the movement due to the freeze thaw cycle we cannot guarantee crack sealing. It is also helpful to understand that just because the crack sealant sinks below the surface of the driveway it doesn’t mean the crack is not sealed. 
Finally, if you see tiny surface cracks less than 1/8” in width after our sealcoating process, don’t be alarmed. Most of the time these tiny cracks don’t penetrate the base, and going back to the cost vs. benefit factor (crack sealing is very labor intensive) most of the time every single crack is not going to be addressed.
