5 Things Sealcoating Contractors Must Do To Earn Repeat Business

Chris Mariani / Jun 25 , 2020

Differentiating your sealcoating business begins in the sales process. That’s because most property managers are seeking your expertise. While some understand sealcoating is an important part of pavement maintenance, many still have misconceptions about what sealcoating can and cannot do. That is where you come in.

Set the Expectation

Make sure your customer knows the purpose of sealcoating. Simply put, pavement sealer helps extend the life of asphalt pavements that are in good condition compared with those left exposed to environmental elements and petroleum fluids. It can also fill hairline cracks; but, it is not a substitute for crack sealant. It cannot restore a worn out pavement or cure defects in the base, sub-base, or mix design.

Specify the Right Product

Most property managers do not understand the differences of various sealers and their advantages or limitations. Explain the pros and cons of refined tar sealer, asphalt emulsion, or petroleum emulsion and make a recommendation on which is best suited for the job. There are also premium versions of each type. Worth noting is that while premium grades cost more up front, they are more cost-effective in the long term because they can reduce the frequency of applications, minimize disruptions, and lower maintenance cost over the life of the pavement.

Educate on Mix Design

Start by explaining that a particular sealer type is used to address a specific condition of pavement. The mix design of that particular sealer type affects its performance. Mix design does not vary widely among refined tar sealers that meet the federal spec. But, among asphalt-based sealers, each has its own mix design with regard to water dilution, additives, amount to be used, and sand loading. Make sure your customer understands the sealer type and mix design you are recommending and present him or her with a copy of the manufacturer’s specification.

Review Proper Application

Timing is critical. Pavements should be sealed one to three years after construction. Thereafter, the process should repeat when asphalt is re-exposed. Sealing too early creates higher probability of surface cracking. Weather is also a big factor; explain the ideal conditions when scheduling. Review the pros and cons of your equipment and the application process. Two coats of sealer are standard and recommended for an effective seal. After application, sealer requires time to set, dry, and cure. A parking lot can re-open after the initial cure, usually within 24 hours. But, wheel scarring and residual odor may not disappear until the final cure, usually within three to four weeks.

Address Post-Job FAQs

Be sure your customers know what to expect after you complete every job. For example, address minor wheel scarring and sand accumulation in low-lying spots. Explain clearly the potential consequences if cure time is not followed. Ultimately, it is important that you and the end user have equal and clear understanding of expectations in order to avoid unneeded conflict. If you always keep it professional with clear facts, you can be recognized as the expert, which results in more work and business growth.

Essential ADA Compliant Products for Parking Lots

Jeff Spencer / Jun 4 , 2020

warning matThese days public health and safety is a prevalent topic in the media and in everyday conversation. We often hear about hand washing and staying at home, but what about when we must go out? For many of us, getting in our car and driving to the store to stock up on food and hygiene products is a frequent errand. But, for a growing number of the population with disabilities, this routine can be risky.

To protect shoppers from current health hazards, commercial properties are focused on limiting capacity, reducing hours of operation, and implementing contactless payment. But, none of this matters if properties are not safe to access in the first place. 

The need to provide safe and accessible parking lots and public walkways is not something new, but it is and always has been essential. Losing sight of this requirement is detrimental to business and to those who require special accommodations.

RAISE AWARENESS

That’s why it is so important for contractors to raise awareness and discuss ADA regulations with property managers. There is a lot to consider, from accessible parking spaces and wheelchair ramps to flush transitions between pedestrian and vehicular areas.

ASSIST IN COMPLIANCE

One of the ways contractors can help properties comply is by installing detectable warning systems. These warning mats help alert the visually impaired when they are about to leave a pedestrian area and enter an area with vehicular traffic. Easily distinguishable in yellow, red, black, or gray, the truncated domes on each warning mat meet very specific federal guidelines.

The Americans with Disabilities Act has developed standards and specifications for the correct usage, positioning, and size of detectable warning systems (click here for more info). Many states have modified the federal installation requirement; therefore, it is important to know the requirements for the state in which you are working. If needed, confer with a certified ADA inspector.

USE THE RIGHT PRODUCTS

GemSeal supplies a complete line of Detectable Warning Mats. Our solutions work for any retrofit, surface-applied application as well as cast-in-place requirements. For the former, we recommend RediMat™ (a flexible option) or AlertTile® (a semi-rigid design). For cast-in-place, try AlertCast® for superior impact resistance, slip resistance, wear resistance, and long-term durability. In addition to detectable warning systems, we also supply preformed thermoplastic ADA symbols, stencils, and ADA signs.


Regardless of ability, all people need equal and safe access to goods and services. With the right ADA compliant products, contractors can help commercial properties lead the way. Please contact your GemSeal representative for more information and pricing.

3 Things You Need to Know About Sealer Additives

Paul Raymond / May 21 , 2020

Additives are designed to enhance and strengthen the natural qualities of sealers. Although it sounds like an elementary process, there are a few variables to consider to achieve effective results.

Being in business for over 60 years, we’ve been asked many questions about sealer additives. To sum it up best, there are three critical things you need to know:

1. Can I incorporate multiple additives into my sealer? 

It is good practice to utilize one additive type sold by the manufacturer of your sealer. Mixing products made by different manufacturers is generally not advisable as not all additive products are compatible with one another. Also make sure that the additive is designed to be used with your sealer type (i.e. refined coal tar, asphalt, petroleum, etc.).

2. What is the difference between sealing with additives and sealing without?

Differences between sealing with and without additives is dependent on the type and amount of additive used, as well as application and environmental conditions. In general, sealing with additives provides the following benefits compared to sealing without:

  • Extends sealer durability and longevity
  • Improves flexibility to help prevent cracking
  • Improves adhesion and cohesion properties of sealer
  • Increases resistance to extreme temperatures
  • Increases resistance to chemicals
  • Increases color retention
  • Shortens the time between coats or re-opening to traffic when a fast-drying additive is used
  • Adds a degree of cost that may be offset by allowing for a greater amount of dilution

Keep in mind that some sealers already have additives incorporated during manufacturing such as GemSeal PolyTar®, so check with your manufacturer before you mix.

3. Which one is right for my job?

Sealer and additive manufacturers provide recommendations for use of their products and include datasheets and mix design tables. The technical datasheet may give a general overview on what that particular additive may be good for, but your sales representative can provide better guidance regarding your specific need. For example, a colder climate may benefit from using an additive that imparts greater flexibility to better withstand freeze/thaw cycles. Areas with high humidity may benefit from a drying agent to help the sealer cure faster. For high-traffic areas or turning lanes, choose an additive that will enhance overall bond strength. GemSeal has a comparison chart to help you select the right one.

2020 Marks New Opportunities for Striping Contractors

Lee F. Lowis / May 5 , 2020

As we emerge from the pandemic, there will be changes that affect virtually every business. Fortunately, the pavement maintenance industry is well equipped to adapt as needs and priorities shift for our customers. The pavement marking sector, for example, is already in position to make a big impression.

If you mark it, they will come

Prior to the pandemic, online ordering and curbside pickup—especially in the grocery industry–had been gaining momentum. Now, due to changing circumstances, it is becoming the norm for grocers, retailers, and restaurants. Striping contractors are integral to the success of this endeavor. After all, parking spaces that are reserved for this service must be clearly zoned, marked, and identified with signage. As the demand for striping increases so, too, are the opportunities for contractors to become a trusted advisor for their customers.

Solutions on the spot

Beyond laying gallons of paint, striping contractors are a much-needed resource for property managers. They can help strategize and recommond proper pavement markings; design new or reconfigure existing layouts to accommodate curbside pickup/delivery areas; and install signs, signposts, bollard covers, speed bumps, and car stops.

Providing direction concerning material selection is also a valuable service. Since many commercial properties—and restaurants in particular—have experienced reduced operating hours, further downtime is not palatable. Rather than closing off sections of a parking lot to perform striping, contractors can specify thermoplastic material as an alternative. Thermoplastic symbols are pre-cut for easy installation without specialized equipment. They can be applied quickly and the material is extremely durable.

Traditional traffic marking paints are always a viable option. Striping contractors can recommend the right formula based on whether the job calls for striping on top of new asphalt or re-striping over existing lines. It’s also important to use a paint that complies with local air quality laws, which can vary from region-to-region and state-to-state.


While the future isn’t clearly mapped out, one thing is certain—striping contractors are essential to keep business moving in the right direction. GemSeal is here to help with products, application equipment, and advice.

Black Diamond Sealer is Solution to San Antonio Decision to Ban Coal Tar

Lee F. Lowis / Jul 8 , 2016

Sometimes things don’t turn out like we had hoped or planned and we have to adapt to the new circumstances. The recent decision of the San Antonio city council to ban the use of coal tar sealers beginning January 1, 2017, means that seal coat contractors in the San Antonio area will soon need to offer something other than refined coal tar products. GemSeal, with nearly 60 years of manufacturing experience, a strong local distributor, and a proven alternative, is ready to help you!

First and foremost, we’re a manufacturer who has been in the sealcoat business for almost six decades. We know a lot about pavement materials and make very high-quality products.  We have done business in San Antonio for almost twenty years by working with Sealcoating Supplies, Inc., an experienced and knowledgeable pavement maintenance products distributor owned and operated by Nancy Navarette. Nancy was involved in the efforts to defend coal tar sealers, and she now stands ready to help her customers make the transition to using different products.  In anticipation of unfortunate bans like this one, we have developed alternative products that enable contractors to continue to stay in business and allow property owners to get a very good result.  One of our alternatives to refined tar sealers is GemSeal Black Diamond, which is comparable to refined tar sealers and superior to asphalt emulsion (AE) sealers.

Black Diamond is a petroleum-based, high-performance sealer that combines the benefits of AE sealer with many of the performance attributes of refined coal tar sealers. This product exceeds AE performance with better coverage, greater durability, fuel resistance, and superior color stability–it goes down black and stays black!

Black Diamond is safe for use in San Antonio, Austin, or anywhere else you need to offer clients an alternative to refined coal tar. It is produced in Dallas using our precision colloid mill and undergoes GemSeal’s unmatched quality control process.

If you’re in San Antonio, call Nancy Navarette of Sealcoating Supplies, our local distributor in San Antonio, at 210-650-0113.
