Hey, driveway enthusiasts! It's the team from Driveway Wizards, back with another driveway maintenance deep dive. Today, we'll take you through the hot topic in the world of driveway sealers – asphalt emulsion sealer versus coal tar sealer. Why do we lean towards asphalt emulsion sealer? Let’s unravel the details.

First off, it’s crucial to know what role driveway sealers play. They act as a shield for your asphalt driveway, defending it from sun damage, chemicals, rain, and various other harmful elements. However, not all sealers offer the same level of protection or benefits. The two most popular choices in the market today are asphalt emulsion sealers and coal tar sealers.

The use of coal tar sealers has been widespread for many years, primarily due to their dark, glossy finish, which adds a touch of charm to any driveway. However, with growing environmental concerns and advancements in technology, asphalt emulsion sealers are increasingly gaining favor.

Why Opt for Asphalt Emulsion Sealer?
  • Friendlier to the Environment and Health

Asphalt emulsion sealers have a much lesser environmental impact compared to coal tar sealers. Coal tar sealers are known for their high levels of polycyclic aromatic hydrocarbons (PAHs), recognized as carcinogens. These harmful compounds can permeate into nearby soil and water sources, posing a risk to humans and wildlife. On the other hand, asphalt emulsion sealers carry significantly fewer PAHs, making them a safer choice for all.

  • Dependable Performance

While coal tar sealers have been praised for their durability, asphalt emulsion sealers offer a competitive edge. They deliver strong resistance to common driveway threats such as gasoline and oil spills, and hold up well against UV radiation, keeping your driveway from losing its color over time. Additionally, asphalt emulsion sealers adhere better to the pavement surface, reducing any chances of peeling or flaking.

  • Ease of Application

Working with asphalt emulsion sealers is simpler compared to coal tar sealers. They're less sticky, hence easier to stir and spread evenly. They also emit a lesser odor, making the application process more tolerable for those keen on DIY projects or professional contractors.

  • Visual Appeal

In terms of aesthetics, asphalt emulsion sealers give your driveway a matte finish, which many homeowners find more sophisticated than the glossy finish that coal tar sealers provide. This matte finish can also conceal minor imperfections more effectively, resulting in a sleek, smooth driveway.

So, it’s clear. Though both coal tar and asphalt emulsion sealers have their merits, asphalt emulsion wins the race in our view. It matches up in durability, is more user-friendly, environmentally safer, and offers a chic, matte finish to boost your driveway’s curb appeal.

At Driveway Wizards, we believe in using high-quality, sustainable products to ensure your driveway stays in prime condition for years. We're confident that asphalt emulsion sealer is the future of driveway maintenance, and we’re excited to bring that future to your doorstep.
