What are Driveway Sealants and How Do They Work?

Driveway sealants stand as a vital component in the maintenance and longevity of your driveway. This post will delve into the intricate world of driveway sealants, their chemical composition, their application process and the science behind their protective features.

Driveway sealants, in simplest terms, are chemical compounds designed to protect driveways from the damaging effects of weather elements, oil spills, UV rays and general wear and tear. They are constructed to bond with the driveway material, forming a protective barrier that enhances the longevity of the driveway.

A deep dive into the chemical composition of driveway sealants uncovers an amalgamation of refined coal tar or asphalt-based products, along with polymers, rubber compounds, and fillers. The primary component, either coal tar or asphalt, provides the sealant with its water-resistant properties. Coal tar, a byproduct of the steel industry, boasts an impressive resistance to water, oil, and UV light. Asphalt, on the other hand, a petroleum byproduct, shows a similar water resistance, but its oil resistance is somewhat inferior to that of coal tar. Polymers and rubber compounds are added to enhance the flexibility and strength of the sealant, delivering improved crack resistance.

Now, it's worth noting that the application process of a driveway sealant is a precise, almost ritualistic task that requires considerable attention to detail. Prior to application, driveways must be thoroughly cleaned and any existing cracks or potholes repaired. This meticulous preparation ensures optimal adhesion between the driveway material and the sealant. With the surface primed, the sealant is applied using a squeegee or spray, with the former method preferred for its ability to deliver a thicker, more uniform coat.

The protective capabilities of driveway sealants are underpinned by the principles of corrosion science - a branch of material science that investigates the degradation of materials due to reactions with their environment. The sealant serves as a barrier, preventing water, oil, and UV light, the chief agents of wear and tear, from interacting with the driveway material. This concept of barrier protection is analogous to the operation of cathodic protection systems employed in maritime structures to prevent corrosion - an eloquent testament to the science behind driveway sealants.

In terms of trade-offs, the choice between coal tar and asphalt-based sealants presents a decision matrix. The superior resistance of coal tar to oil and UV light suggests its suitability for driveways that are heavily used or located in areas with high UV exposure. However, coal tar sealants emit higher levels of volatile organic compounds (VOCs), which are harmful to the environment. Asphalt-based sealants, while inferior in resistance, emit fewer VOCs, and are a more environmentally friendly option.

The decision to apply a driveway sealant transcends mere aesthetics. It assumes the role of an investment, preserving the integrity and longevity of the driveway, and ultimately, enhancing the value of the property it adorns. As the physicist R. Buckminster Fuller aptly put it, "Don't fight forces, use them". By applying a driveway sealant, you aren't battling the forces of nature and wear and tear, you're using the science of corrosion control to work in your favor.

So, whether you're considering a sealant for your suburban home driveway or the expansive parking lot of a commercial building, remember, it's not just about the initial appeal. It's about understanding the science, the environmental implications, and making a well-informed decision that contributes to the longevity of your investment. Driveway sealing is a synergy of chemistry, material science, and economics; a testament to the intricate balance between protection, aesthetics, and sustainability.
