Expert Recommendations

Based on the recommendations from construction professionals and civil engineers, the premium-grade coal tar sealer is often considered the best choice for driveways. Here’s why:

Best for Durability

Coal tar sealers offer excellent protection against harsh elements, including UV rays, water, and chemicals. They provide long-lasting protection and can extend the life of your driveway. Their ability to penetrate deep into the asphalt surface creates a strong bond, preventing cracks and deterioration.

Best for Eco-friendliness

For those who prioritize environmental friendliness, asphalt emulsion or latex sealers are better choices. These sealers are water-based and offer good protection against UV rays and weather.

Best for Extreme Conditions

Rubberized sealers are ideal for areas with extreme weather conditions due to their added flexibility and durability. They provide excellent protection and are often used in harsh climates.

Application Tips

To ensure the best results when applying any asphalt sealer, follow these expert application tips:

Thorough Cleaning: Clean the driveway thoroughly before sealing to remove dirt and debris. This ensures a better bond between the sealer and the surface. Fill Cracks: Fill any cracks or holes in the driveway to prevent water ingress and further damage. Temperature Check: Apply the sealer when temperatures are above 50°F and there’s no rain forecasted for at least 24 hours. This ensures optimal curing and drying conditions. Check Manufacturer Instructions: Always follow the manufacturer's instructions and local regulations regarding sealers. Some areas have restrictions on certain products, such as coal tar.

By choosing the best asphalt sealer and following proper application techniques, you can ensure the longevity and aesthetic appeal of your driveway for years to come.
