Pressure washing your patio can deliver amazing results, restore its appearance, create a safer environment, and improve your outdoor space.
But what if your driveway isn’t made of patio slabs? What happens when you want to pressure wash a completely different surface?
In this article, we’ll explore whether it’s possible, safe, and advisable to pressure wash a tarmac surface.
Lets begin.
Understanding Tarmac Composition
Before we dive into the details, its important to understand the composition of tarmac. Tarmac consists primarily of a mixture of aggregates, like crushed stone or gravel, bound together with bitumen.
The crushed stones give the tarmac its strengths for heavy loads, whilst the bitumen agent serves as a waterproofing agent. This waterproofing prevents water infiltration that can lead to cracks and deterioration.
This being said, exposure to UV rays and harsh elements can overtime degrade this protective layer, making regular maintenance imperative. Regular pressure washing services can help preserve the integrity of the tarmac surface.
When working with any tarmac surface, pay particular attention to its color and condition as any changes can indicate underlying issues. For instance, if the surface becomes brittle or begins to fade, it might need repairs and a sealant application.
Benefits of Pressure Washing
One of the main benefits of pressure washing is its ability to remove dirt, grime, and stains that accumulate over time. This not only improves the appearance of your tarmac but also prevents deterioration that could require costly repairs later down the line.
Regular maintenance through pressure washing can also prevent damage from harmful elements, extending the lifespan of your tarmac.
Another key advantage is the efficiency of pressure washing. With high-pressure water jets, you can clean large areas quickly, saving you time and effort compared to traditional cleaning methods.
Here’s a quick overview of the benefits:
| Benefit | Description | Impact |
|---|---|---|
| Aesthetic Improvement | Restores the original look of tarmac | Increases property value |
| Time Efficiency | Cleans large areas quickly | Saves labor costs |
| Safety Improvement | Removes slippery substances | Reduces accident risks |
Risks of Pressure Washing Tarmac
While pressure washing can be a great way to clean surfaces, using it on tarmac does come with risks. Tarmac is a softer material than concrete or paving slabs, making it more vulnerable to damage from high-pressure water. Too much force can loosen stones, break the surface, or even cause cracks.
Another risk is water infiltration. If there are any weak spots or cracks, high-pressure water can seep in, weakening the base and leading to further damage over time. This can result in potholes or uneven surfaces, especially in older tarmac.
Using the wrong nozzle or pressure setting can also strip away the top layer of the tarmac, leaving it rough and more likely to wear down faster. This not only affects its appearance but can also make it more prone to further damage from weather and everyday use.
To avoid these risks, it’s important to use low pressure, the right cleaning technique, and a gentle detergent and consult with professional cleaning operators if you are unsure as they will be able to provide expert guidance on safe practices.
Steps to Safe Pressure Washing Techniques
Now that you understand the composition of tarmac plus the benefits and risks, it’s important to employ safe techniques to protect both the surface and yourself whilst carrying out the clean.

Here are some key steps to perform a safe, effective clean:
Wear Protective Gear
Always wear safety goggles, gloves, and sturdy footwear to protect yourself from debris and any chemical cleaners you might use.
Choose the Right Pressure Setting
Use a lower pressure setting, typically around 1500-2000 PSI, to avoid damaging the tarmac. Higher pressures can cause cracks and surface degradation.
Use a Fan Spray Nozzle
Opt for a fan spray nozzle instead of a narrow jet. This spreads the pressure evenly and prevents concentrated force on a single spot.
Maintain a Safe Distance
Keep the nozzle at least 12 inches away from the tarmac surface. This distance helps reduce the risk of damaging the material while still effectively cleaning.
Rinse and Allow to Dry
After washing, rinse thoroughly and let the tarmac dry completely to assess the results and ensure no damage has occurred.
Alternative Cleaning Methods
If you are looking for other ways to clean your tarmac without relying on pressure washing, there are several alternatives.
One way is using a broom or stiff brush with soapy water. This allows you to scrub away dirt and grime without damaging the surface. Mix a mild detergent with warm water, apply it to the tarmac, and then scrub vigorously.
Another is using a leaf blower. This is quick and can help prevent dirt build-up before it becomes a bigger issue. For tougher stains consider using a degreaser specifically designed for tarmac, apply it directly to the stain, let it sit for a while, and then scrub it away.
If you prefer a more natural solution, vinegar and baking soda can work wonders. Sprinkle baking soda on the stain, spray vinegar over it, let it fizz, and then scrub the area clean.
Maintenance Tips for Tarmac
By following a few simple steps, you can extend your tarmac lifespan and maintain its appearance. Here’s a few maintenance tips you can follow:
- Regular Cleaning: Sweep away debris, leaves, and dirt regularly. This prevents stains and keeps your tarmac looking fresh.
- Inspect for Damage: Check for cracks or potholes. Addressing these issues early can prevent further deterioration and costly repairs later.
- Sealcoat Application: Apply a sealcoat every couple of years. This protective layer improves durability and shields against oil spills and UV damage.
- Avoid Heavy Loads: Keep heavy vehicles off your tarmac when possible. Excess weight can lead to ruts and cracks, compromising its integrity.
Conclusion
So yes, in effect you can pressure wash tarmac, but it’s important you follow some simple rules.
Stick to lower pressure settings, use a fan spray nozzle to protect the surface, remember to maintain a safe distance, and wear protective gear.
By following these tips, you can keep your tarmac looking great and dramatically extend its lifespan.
