What is Tarmac Sealing

Tarmac sealing is a maintenance practice that applies a waterproof coating to tarmac surfaces, extending their life by protecting against environmental and man made damages. Tarmac surfaces are durable but they can weather, UV exposure, moisture and chemical spills can cause cracking, fading and overall degradation. Sealing acts as a barrier , prevents moisture from getting in, shields against the sun’s harmful rays and resists oil and chemical damage . It also restores the tarmac’s original black look, adds curb appeal . Importantly it fills small cracks preventing them from getting bigger and causing more serious problems. By incorporating tarmac sealant into your maintenance routine you can extend the life and beauty of your driveways and pavements and avoid costly repairs and keep your investment looking and functional.

Types of Tarmac Sealers

Coal Tar Sealers: Made from refined coal tar, these offer strong water resistance, gasoline, oil and UV light. They’ve been a popular choice for their durability and shiny look. But they emit high levels of volatile organic compounds (VOCs) and are a potential environmental and health risk. 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 are synthetic, offer excellent water resistance, gasoline, oil and UV rays. Acrylic sealers emit lower levels of volatile organic compounds (VOCs) than coal tar sealers, they’re a safer choice for the environment. They offer longer lasting protection but at a higher cost.
Asphalt Emulsion: These are water-based sealers that offer moderate protection and are more environmentally friendly 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 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 environmental impact, durability, cost and specific needs of your pavement. Eco-friendly options are becoming more popular due to their lower environmental footprint and safety benefits, while traditional sealers like coal tar and acrylic offer strong protection and aesthetic appeal.

Things to Consider When Choosing Your Driveway Sealant

Climate and Weather: Polymer modified sealers are best suited for areas with extreme weather conditions. They’re designed to withstand temperature fluctuations and offer enhanced protection against ice melt chemicals.
Traffic Volume: Coal tar or polymer-modified sealers for high traffic areas. These sealers provide a strong barrier against frequent vehicle movement and wear and tear.
Desired Finish: Glossy finish and colour enhancement. Acrylic or polymer-modified sealers are ideal. These products not only protect the tarmac but also improve its appearance by giving it a richer, more vibrant look.
Environmental and Health Considerations: Asphalt emulsion sealers or eco-friendly options like soy-based sealers for those concerned with environmental and health impacts. These products emit lower levels of VOCs and are safer for the environment and human health.

How to Seal Tarmac

Preparation: Clean the tarmac surface thoroughly 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 dry completely.
Application: Apply on a dry, mild day. Stir the sealer well 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, work in small sections to ensure even coverage without missing any spots.
Drying Times: Allow the first coat to dry completely, 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 allow it to fully set.
Maintenance and Reapplication: Inspect the sealed surface annually for wear and 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.

Tarmac Restorer: An Alternative to Tarmac Sealer

Tarmac restorer products are designed to revive aged, faded or worn tarmac driveways, an alternative to traditional sealers. Unlike sealers that provide a protective layer to prevent damage from water, UV rays and chemicals, restorers penetrate the tarmac to restore its original colour and texture. They are ideal for surfaces too damaged for standard sealers, effectively revitalising the appearance and extending the life of the tarmac without the need for expensive resurfacing. Using a tarmac restorer can greatly improve the curb appeal of a property by enhancing the surface’s appearance while filling minor cracks and imperfections, a cost effective solution for older tarmac areas.
