The Definitive Guide to Dual Application in Asphalt Sealcoating


You're probably no stranger to the term 'sealcoating,' especially if you live in Orlando, FL. The Sunshine State's beautiful weather is often a double-edged sword for the highways and byways of the city, contributing to asphalt's accelerated degradation. Sealcoating is the metaphorical shield that defends against O-town's sun, rain, and traffic, protecting your asphalt surfaces from adversaries like oxidation and water penetration. But what about 'dual application'? What extra benefits does this flashier-sounding method bring to the table?

In the competitive domain of asphalt preservation, knowing the nuances of sealcoating is vital. Whether you manage a property or are simply looking to enhance and maintain your driveway, the considerations around dual application are key to making the most of your investments. Join us as we uncover the why, when, and how of integrating dual application in your sealcoating process, ensuring that your surfaces remain resilient and visually pleasing for longer.


What is Dual Application in Sealcoating?

In straightforward terms, dual application or double-layered sealcoating involves applying two coats of sealant to the asphalt surface, usually in quick succession. The first coat acts as a primer, adhering closely to the asphalt and filling in the smaller crevices and pores. The second coat, applied shortly after, provides robustness and a smooth, homogeneous finish. This approach results in a more durable coating and prolongs the lifespan of the sealcoating by several years.

Sealcoating Fundamentals

Before we jump into the intricacies of dual application, it's important to understand the basics. Sealcoating is a bit like sunscreen for your skin. It protects and prolongs. Asphalt, a mix of aggregate and bitumen, is prone to wear from UV rays, rain, and even air pollution. Sealcoating, typically applied every 2-3 years, creates a protective layer that not only repels water and spills but also maintains the asphalt's essential oils, preventing it from becoming brittle.

Why Choose Dual Application?

The primary motivation behind the dual application strategy is to create a significantly more durable and longer-lasting sealcoating. The first coat, often a bit more dilute for better soakage, ensures that every tiny nook on the surface is addressed. The second, typically stronger, delivers an even, impregnable barrier.

In sunny Orlando, FL, where the weather can be extreme at times, durability isn't a luxury — it's a necessity. Dual application resists wear and tear from vehicle traffic and protects against the relentlessly harsh UV rays. It also results in a more aesthetic finish, complementing the smoothness and darkening characteristics often sought after in freshly sealed asphalt.

Prolonged Protection

A double coat means double the protection. The first layer fixes existing issues like small cracks and hairlines, while the second gives a solid, uniform shield that repels water and prevents the surface from wearing down prematurely. This process ensues a longevity that single-layered applications simply can't claim.

Support Against Traffic

Sealcoating is your asphalt's main line of defense, but what happens when you strengthen that with an additional barrier? You get a surface that can withstand heavier loads and more frequent traffic without showing signs of distress. The extra layer provided by dual application is critical for properties with high vehicle frequency, such as parking lots and commercial driveways.

When is the Right Time for Dual Application?

Knowing the ideal conditions and timelines for a dual-layer sealcoating application is crucial. Typically, it is recommended to use this approach when the surface has not been sealcoated previously, as it allows for a thorough treatment of the asphalt. However, in instances where surfaces have been under-treated or a significant time has lapsed since the last treatment, dual application can serve as a restoration measure.

New Construction

For brand-new asphalt, dual application can set a robust foundation for long and trouble-free usage. It's an insurance policy that your investment will serve its purpose without the need for repair sooner than expected.

Rehabilitating Neglected Surfaces

In cases where asphalt surfaces have suffered prolonged exposure to harsh elements or have been under-maintained, dual application can help in rehabilitation. The first coat's penetrating properties along with the second coat's protective ones can transform the quality of your surface, albeit more dramatically than a single-layer approach would allow.

How to Implement Dual Application

Choosing to use the dual application method also requires a conscientious approach to preparation and execution. The process isn't complex, but it does command attention to detail and a commitment to timing.

Surface Preparation

The surface must be clean, free of oil or dirt, and free from standing water. Any repairs or filling should be completed before sealing. This includes addressing any significant cracks or areas that may sag or pool water.

First Coat Application

The first layer, usually diluted by around 25% to 30%, should be applied using the spray method. This allows for efficiency and ensures the layer smooths out nicely across the surface, filling in the small gaps and crevices that can lead to bigger problems down the line.

Timely Second Coat

The second coat should be applied as soon as the first begins to set, usually within a couple of hours. This is when the two layers can bond most effectively, creating a unified, strong surface.

The Dual Application Advantage

The benefits of a dual-layer sealcoating are evident. It prolongs the new, dark look of fresh asphalt, protects against fading and cracking due to UV rays, and offers more thorough protection against the elements. Dual application becomes not just a best practice but an investment in the longevity and aesthetics of your asphalt surfaces.

Longer Time Between Coatings

By providing a superior layer of protection, dual application effectively extends the life of your sealcoating, reducing the frequency with which you must reapply it. This can lead to cost savings and less disruption to your property's use.

Enhanced Aesthetics

Orlando's beautiful weather demands surfaces that can keep up aesthetically. Dual application ensures a uniform and deep black finish that enhances the look of your property's exterior, providing a positive visual impression to guests and customers alike.


In Conclusion
