Your driveway is one of the most used and visible parts of your home. Whether you’ve just had a brand-new tarmac driveway installed or your current driveway is showing signs of wear, sealing it may have crossed your mind. But is sealing your tarmac driveway necessary? And, more importantly, is it worth the investment?
Sealing your tarmac driveway helps protect it from water damage, UV rays, oil spills, and general wear, extending its lifespan. It prevents cracks and fading while maintaining a fresh appearance. Regular sealing is a worthwhile investment to keep your driveway durable and looking its best over time.
In this post, we’ll explore tarmac sealing, the benefits of sealing your new driveway, and whether it’s a smart choice for extending the life of your tarmac.
What Is Tarmac Sealing?
Tarmac sealing involves applying a protective sealant layer over the surface of your tarmac driveway. This sealant acts as a barrier, shielding the tarmac from the damaging effects of the elements, heavy traffic, oil spills, and even UV rays. It’s similar to giving your driveway a protective coat of armour.
Sealing is particularly important because tarmac is porous by nature. Over time, water, oils, and chemicals can seep into the surface, weakening the structure and causing cracks, potholes, and fading. A properly applied sealant not only protects the driveway but also helps maintain its appearance, keeping it looking fresh and new for longer.
The Benefits of Sealing a Tarmac Driveway
There are several advantages to sealing your tarmac driveway, especially if you’re looking to enhance its lifespan and maintain its pristine look.
1. Protection from Water Damage
One of the most significant benefits of sealing a tarmac driveway is the protection it offers from water damage. Without a sealant, water can penetrate the tarmac surface, particularly through small cracks or imperfections. Over time, this water can freeze and expand (in colder climates), leading to the formation of potholes and even larger cracks.
By sealing the driveway, you create a barrier that prevents water from seeping in, reducing the chances of erosion and deterioration. This is especially important if your driveway is prone to water pooling or if you live in an area with heavy rainfall.
2. Prevents UV Damage and Fading
Tarmac driveways are constantly exposed to UV rays from the sun, which can cause the surface to fade and degrade over time. The once rich black colour of a freshly laid tarmac driveway can quickly turn into a dull, grey surface if left unprotected.
Sealing your driveway helps protect it from UV radiation, preserving the original colour and preventing the tarmac from becoming brittle. This not only keeps the driveway looking newer for longer but also helps maintain its structural integrity.
3. Resistance to Oil and Chemical Spills
If your driveway is used frequently by vehicles, there’s a good chance it will be exposed to oil, petrol, and other chemicals. These substances can seep into the porous tarmac and cause permanent stains or, worse, weaken the surface, making it prone to cracking and damage.
A sealed driveway creates a protective layer that resists the absorption of oils and chemicals, making it easier to clean up spills and reducing the risk of long-term damage.
4. Reduces Cracking and Potholes
Cracks are an inevitable part of any driveway’s lifecycle, especially if it’s exposed to harsh weather conditions or frequent use by heavy vehicles. However, sealing can help minimise cracking by filling in minor surface imperfections and acting as a barrier that prevents further cracking.
If left unchecked, small cracks can quickly turn into larger ones or even potholes, leading to more extensive damage that will require costly repairs. Sealing the driveway helps prevent these small cracks from growing, saving you money on future maintenance.
5. Enhances Appearance
A sealed driveway looks newer and more polished. Tarmac sealants often restore the deep black colour that’s synonymous with freshly laid tarmac, which can significantly improve your home’s curb appeal. Over time, the colour of the tarmac fades due to exposure to the sun and the elements, but sealing it can give it a new lease of life, making your property look well-maintained and attractive.
6. Extends the Driveway’s Lifespan
Ultimately, sealing your driveway is about protecting your investment. A well-maintained, sealed driveway can last significantly longer than an unsealed one. By preventing water, UV damage, and oil stains, you’re ensuring that your driveway remains in good condition for many more years, reducing the need for frequent repairs or resurfacing.
In the long run, sealing your driveway can save you both time and money, making it a worthwhile investment for any homeowner.
Potential Drawbacks of Sealing a Tarmac Driveway
While the benefits of sealing are clear, there are also some potential downsides to consider.
1. Upfront Cost
Sealing a driveway does come with an upfront cost, particularly if you hire professionals to do the job. The cost will depend on the size of your driveway, the type of sealant used, and the labour involved. However, it’s important to weigh this cost against the potential savings you’ll achieve from preventing future repairs.
2. Need for Regular Maintenance
Sealing isn’t a one-time solution. To maintain the protective barrier, you’ll need to reseal the driveway every few years, depending on wear and tear. This adds ongoing maintenance to your home improvement list, but it’s a small price to pay to protect your driveway from more extensive damage.
3. Timing and Weather Conditions
Sealing requires the right weather conditions to ensure the sealant cures properly. You’ll need a few days of dry, mild weather to complete the process. Rain, extreme heat, or freezing temperatures can affect how the sealant sets, meaning you may need to plan carefully around the weather forecast to ensure proper application.
How Often Should You Seal a Tarmac Driveway?
The general recommendation is to reseal a tarmac driveway every 2 to 4 years, depending on the amount of wear it experiences. Factors like weather, vehicle traffic, and exposure to oil and chemicals can influence how often your driveway needs sealing.
For example, driveways exposed to harsh weather conditions or heavy vehicle use may require sealing more frequently than those in mild climates or with light use. Regularly inspecting your driveway for signs of fading, cracking, or water damage can help you determine the best time to reseal.
DIY vs. Professional Sealing
When it comes to sealing your tarmac driveway, you have two options: DIY sealing or hiring a professional. Let’s look at the pros and cons of each.
DIY Sealing
For those who enjoy tackling home improvement projects themselves, DIY driveway sealing is an option. DIY sealants are readily available at most hardware stores, and the process involves cleaning the driveway, applying the sealant, and allowing it to cure.
- Pros: Lower cost, satisfaction of completing the job yourself.
- Cons: Requires time, effort, and precision. Applying sealant unevenly or missing areas can reduce its effectiveness.
Professional Sealing
Hiring a professional to seal your driveway ensures the job is done right, using high-quality materials and expert techniques. Professionals can assess your driveway’s condition, recommend the best type of sealant, and apply it evenly for a smooth, long-lasting finish.
- Pros: Higher quality, less hassle, longer-lasting results.
- Cons: Higher initial cost, but this can be offset by the longer-lasting protection and reduced need for frequent resealing.

Signs Your Tarmac Driveway Needs Sealing
Not sure if your driveway needs sealing? Here are a few key signs to watch for:
1. Fading Colour
If your once-black driveway has started to fade to a dull grey, it’s a clear sign that UV rays have taken their toll, and the surface is no longer adequately protected.
2. Small Cracks
Minor cracks in the tarmac can quickly grow if left unaddressed. Sealing your driveway can fill in these small cracks and prevent larger issues from developing.
3. Water Pooling or Soaking In
If water pools on the surface or seems to soak into the tarmac rather than running off, it’s a sign that the driveway’s porous surface needs sealing.
4. Stains from Oil or Chemicals
Stains from vehicle oil, petrol, or other chemicals indicate that the tarmac is absorbing these substances, which can weaken the surface over time. Sealing helps prevent further absorption.
How to Choose the Right Sealant for Your Tarmac Driveway
Not all sealants are created equal. Here’s what to consider when choosing the best sealant for your driveway.
1. Water-Based vs. Solvent-Based Sealants
Water-based sealants are easier to apply and clean up, but solvent-based sealants tend to last longer and provide stronger protection. Both options offer good results, but solvent-based sealants may be a better choice for driveways exposed to heavy traffic.
2. UV Resistant Sealants
If your driveway gets a lot of sun exposure, choose a sealant that offers UV protection to prevent fading and degradation.
3. Oil and Chemical Resistant Sealants
For driveways frequently exposed to vehicle oils or chemicals, opt for a high-performance sealant that provides extra resistance to spills, ensuring your driveway stays in top condition.
Step-by-Step Guide to Sealing Your Tarmac Driveway
If you’re thinking about sealing your driveway yourself, here’s a basic guide to help you through the process:
- Clean the Driveway: Sweep away dirt and debris, and clean any oil stains with a degreaser.
- Repair Cracks: Fill small cracks with a crack filler before applying the sealant.
- Apply the Sealant: Use a squeegee or roller to apply an even coat of sealant across the surface.
- Allow to Cure: Let the sealant dry and cure for at least 24-48 hours before using the driveway.
Conclusion: Should You Seal Your Tarmac Driveway?
Sealing your tarmac driveway is a smart investment that offers numerous benefits, from protecting it against water and UV damage to extending its lifespan and improving its appearance. While there is an upfront cost and the need for regular maintenance, the long-term savings and enhanced curb appeal make sealing a worthwhile option for most homeowners.
