Tarmac Driveway Sealing and Maintenance Tips in Dublin

Tarmac driveways have become a popular choice for homeowners in Dublin and beyond due to their durability and attractive appearance. However, to ensure that your tarmac driveway stays in top condition and maintains its aesthetic appeal, proper sealing and regular maintenance are essential. In this article, we’ll explore the best practices for tarmac driveway sealing and maintenance in Dublin.

The Importance of Tarmac Driveway Maintenance

Maintaining your tarmac driveway is not just about aesthetics; it’s also a matter of preserving the structural integrity of the surface. In Dublin, where the weather can be unpredictable and harsh, neglecting your tarmac driveway can lead to various issues, including cracks, potholes, and deterioration. Regular maintenance can extend the life of your tarmac driveway and save you from costly repairs in the long run.

Tarmac Driveway Sealing

Tarmac driveway sealing is a crucial step in protecting your investment and ensuring your driveway looks its best. Here’s what you need to know about the sealing process.

When to Seal Your Tarmac Driveway

Sealing your tarmac driveway is not a one-time job. The frequency of sealing depends on various factors, including the weather conditions, the driveway’s age, and the level of wear and tear. As a general guideline, it’s recommended to seal your driveway every 3-5 years in Dublin.


Proper preparation is essential for a successful tarmac driveway sealing. Here are the steps involved:

  1. Clean the Surface: Start by thoroughly cleaning the driveway. Remove debris, dirt, and any vegetation that may have taken root in cracks. A pressure washer can be a handy tool for this task.
  2. Repair Cracks: Inspect the driveway for cracks, and patch them up using tarmac repair products. This step is crucial to prevent water from seeping beneath the surface.

Choosing the Right Sealant

Selecting the right sealant is critical for the longevity of your tarmac driveway. Two main types are available:

  1. Coal Tar Sealers: These are traditional sealants that offer excellent protection. They are known for their resistance to UV rays and provide a deep, black finish. However, they are no longer recommended in some areas due to environmental concerns.
  2. Asphalt Emulsion Sealers: These sealants are water-based and are considered more environmentally friendly. They offer good protection and are widely used in Dublin. While they might not provide as deep a black finish as coal tar sealers, they are a suitable choice for tarmac driveways.

Applying the Sealant

Once you’ve chosen the appropriate sealant, it’s time to apply it. Here’s how:

  1. Start at the Edges: Begin by applying the sealant along the edges of the driveway using a brush or a squeegee. This helps create a clean border.
  2. Work in Sections: Divide your driveway into manageable sections, and apply the sealant evenly. Ensure you spread it out smoothly, avoiding puddles or thick areas.
  3. Overlap Strokes: As you apply the sealant, overlap your strokes slightly to ensure complete coverage.
  4. Let it Cure: Allow the sealant to cure for at least 24-48 hours before using the driveway. This time may vary depending on the weather conditions in Dublin.

Tarmac Driveway Maintenance

Sealing is a preventive measure, but regular maintenance is equally important. Here are some maintenance tips to keep your tarmac driveway in top condition:

Regular Cleaning

Dublin’s weather can be quite challenging for driveways. Rain, snow, and even leaves can leave dirt and debris on the surface. Regularly sweep or use a leaf blower to keep your tarmac driveway clean. Remove any oil or chemical stains promptly, as they can penetrate the surface and cause damage.

Avoid Heavy Loads

While tarmac driveways are durable, excessive weight can cause damage. Avoid parking heavy vehicles or equipment on your driveway for extended periods. If you must, consider placing boards or plywood beneath the tires to distribute the weight.

Fill Cracks and Potholes

Cracks and potholes can be unsightly and lead to further damage if not addressed promptly. Invest in quality tarmac repair products to fill these gaps and prevent water from seeping beneath the surface.

Weed Control

Weeds can be persistent and can push through cracks in your tarmac driveway. Regularly inspect and remove any weeds that appear. Additionally, consider using weed killer products to prevent their return.

Regular Inspections

Frequent inspections are the key to early problem detection. Periodically check your tarmac driveway for signs of wear and tear, such as cracks or areas with loose tarmac. Promptly addressing these issues can prevent them from worsening.

Professional Assistance

While many aspects of tarmac driveway sealing and maintenance can be done by homeowners, it’s essential to recognize when it’s time to call in the professionals. Professional assistance may be necessary for the following tasks:

  1. Resealing: While sealing can be a DIY project, resealing is best done by professionals, as it involves cleaning, repairing, and reapplying the sealant.
  2. Extensive Repairs: If your tarmac driveway has severe damage, such as large potholes or widespread cracking, it’s best to leave the repairs to experts who can ensure a long-lasting solution.
  3. Resurfacing: In some cases, resurfacing may be required to restore the appearance and functionality of your driveway. This is a complex job that should be performed by experienced contractors.


A well-maintained tarmac driveway not only enhances the curb appeal of your property but also ensures its longevity. In Dublin, where the weather can be challenging, proper sealing and maintenance are essential. By following the tips outlined in this article and knowing when to seek professional assistance, you can keep your tarmac driveway in top condition for years to come. Remember, the key to a beautiful and functional driveway is regular care and attention.
