Understanding Tarmac Sealing

Tarmac sealing is an essential maintenance practice that applies a water-resistant coating to tarmac surfaces, significantly extending their lifespan by safeguarding against environmental and man-made damages. Tarmac surfaces , known for their durability, are nonetheless vulnerable to weathering, UV exposure, moisture, and chemical spills , which can lead to cracking, fading, and overall degradation. Sealing acts as a barrier , preventing moisture from penetrating the surface, shielding against the sun’s harmful rays, and resisting oil and chemical damage . Additionally, it restores the tarmac’s original black luster, enhancing curb appeal . Importantly, the process helps fill small cracks, preventing them from widening and causing more serious issues. By incorporating tarmac sealant into regular maintenance routines, property owners can prolong the life and beauty of their driveways and pavements, avoiding costly repairs and maintaining their investment’s value and functionality.

Types of Tarmac Sealers

  • Coal Tar Sealers: These are made from refined coal tar, offering strong resistance to water, gasoline, oil, and UV light. They have been a popular choice for their durability and ability to provide a sleek, shiny appearance. However, they emit high levels of volatile organic compounds (VOCs), leading to potential environmental and health concerns. Some states have banned or limited the use of coal tar sealers due to their carcinogenic properties and the environmental impact of their runoff.
  • Acrylic Sealers: Known for their durability and ability to enhance the colour and texture of the tarmac. These sealers are synthetic, providing excellent resistance to water, gasoline, oil, and UV rays. Acrylic sealers emit lower levels of volatile organic compounds (VOCs) than coal tar sealers, making them a safer choice for the environment. They offer longer-lasting protection but come at a higher price.
  • Asphalt Emulsion: These are water-based sealers that offer moderate protection and are environmentally friendlier than coal tar sealers. They’re easier to apply and have fewer odours, but may require more frequent reapplication.
  • Polymer Modified Driveway Sealer: A polymer-modified driveway sealer is a subtype of asphalt emulsion sealer. Polymer-modified asphalt emulsions are enhanced versions of standard asphalt emulsions, formulated with added polymers to improve their physical properties, performance, and durability.

Eco-Friendly Options: Eco-friendly sealers is a sustainable alternative. You can indeed find on the sealer market soy-based products low in odour and free from polycyclic aromatic hydrocarbons (PAHs), harmful compounds found in traditional sealers.

Choosing the right tarmac sealer involves weighing factors such as the environmental impact, durability, cost, and specific needs of your pavement. Eco-friendly options are increasingly popular due to their lower environmental footprint and safety benefits, while traditional sealers like coal tar and acrylic offer strong protection and aesthetic appeal.

Factors to Consider When Choosing Your Driveway Sealant

  • Climate and Weather: Polymer-modified sealers are best suited for areas with extreme weather conditions. They are designed to withstand temperature fluctuations and offer enhanced protection against the damaging effects of ice melt chemicals.
  • Traffic Volume: Coal tar or polymer-modified sealers are recommended for areas that experience heavy traffic. These sealers provide a durable barrier against frequent vehicle movement and the associated wear and tear.
  • Desired Finish: For a glossy finish and enhanced colour, acrylic or polymer-modified sealers are ideal. These products are formulated to not only protect the tarmac, but also to improve its appearance by providing a richer, more vibrant look.
  • Environmental and Health Considerations: Asphalt emulsion sealers or eco-friendly alternatives like soy-based sealers are recommended for those concerned with environmental and health impacts. These products emit lower levels of VOCs and are safer for both the environment and human health.

Step-by-Step Guide to Sealing Tarmac

  1. Preparation: Begin by thoroughly cleaning the tarmac surface to remove debris, dirt, and oil stains. Use a stiff-bristled brush and a suitable cleaner for tough stains. Repair any cracks or holes with a tarmac-compatible filler to ensure a smooth surface. Allow repairs to completely dry.
  2. Application: Choose a dry, mild day for application. Stir the sealer thoroughly before use. Apply the tarmac sealer evenly using a squeegee or a seal coating brush for smaller areas and a sprayer for larger surfaces. Start from one end, working in small sections, to ensure even coverage without missing any spots.
  3. Drying Times: Allow the first coat to dry thoroughly, typically for at least 24 hours, before applying a second coat if necessary for better protection. Avoid walking or driving on the sealed surface for at least 48 hours to ensure it is fully set.
  4. Maintenance and Reapplication: Inspect the sealed surface annually for any wear or damage. Clean the surface regularly to remove debris. Reapply the tarmac sealer every 2-4 years, depending on traffic and weather conditions, to maintain its protective properties and keep the tarmac looking fresh.

By following these steps, you can extend the life of your tarmac driveway surface, enhance its appearance, and ensure it remains protected against the elements.

Tarmac Restorer: An Alternative to Tarmac Sealer

Tarmac restorer products are specifically designed to rejuvenate aged, faded, or worn tarmac driveways, offering an alternative to traditional sealers. Unlike sealers that primarily provide a protective layer to prevent damage from water, UV rays, and chemicals, restorers penetrate the tarmac to restore its original color and texture. They are particularly beneficial for surfaces too degraded for standard sealers, effectively revitalizing the appearance and extending the life of the tarmac without the need for expensive resurfacing. Using a tarmac restorer can significantly improve the curb appeal of a property by enhancing the surface’s aesthetics while also filling minor cracks and imperfections, making it a cost-effective solution for maintaining older tarmac areas.
