When it comes to maintaining a newly installed asphalt driveway, one of the most common questions that homeowners have is whether or not they should wet it down. The answer to this question is not as straightforward as it might seem, as it depends on a variety of factors, including the type of asphalt used, the climate and weather conditions in your area, and the age of the driveway. In this article, we will delve into the details of why wetting down a new asphalt driveway might be necessary, the benefits and drawbacks of doing so, and provide guidance on how to properly care for your new driveway.
Understanding Asphalt and Its Maintenance
Asphalt is a popular choice for driveways due to its durability, flexibility, and cost-effectiveness. It is made from a mixture of petroleum-based products, aggregate (such as crushed stone or gravel), and sand. The installation process involves laying down a layer of asphalt, which is then compacted to create a smooth, even surface. However, asphalt is not maintenance-free, and proper care is necessary to extend its lifespan and prevent damage.
The Importance of Curing
One of the most critical aspects of asphalt maintenance is the curing process. Curing refers to the process by which the asphalt binder (the substance that holds the aggregate and sand together) hardens and becomes more stable. This process can take several weeks to several months, depending on the type of asphalt used and environmental conditions. During this time, it is essential to protect the asphalt from damage, including water, oil, and excessive traffic.
Role of Water in Curing
Water plays a significant role in the curing process of asphalt. While it might seem counterintuitive to wet down a new asphalt driveway, water can actually help to accelerate the curing process. When water evaporates from the surface of the asphalt, it helps to cool the material, which can slow down the curing process. By wetting down the driveway, you can help to control the temperature of the asphalt, promoting a more even and stable cure. However, it is crucial to use water sparingly and only when necessary, as excessive water can damage the asphalt and lead to premature deterioration.
Benefits of Wetting Down a New Asphalt Driveway
There are several benefits to wetting down a new asphalt driveway, including:
Wetting down the driveway can help to reduce the risk of thermal cracking, which occurs when the asphalt expands and contracts due to temperature changes. By keeping the surface cool, you can reduce the stress on the asphalt and prevent cracks from forming. Additionally, wetting down the driveway can help to prevent oil spills and stains from penetrating the surface of the asphalt. Oil can damage the asphalt binder, leading to soft spots and other forms of deterioration. By wetting down the driveway, you can help to prevent oil from seeping into the asphalt and causing damage.
Drawbacks of Wetting Down a New Asphalt Driveway
While there are benefits to wetting down a new asphalt driveway, there are also some potential drawbacks to consider. Excessive water can damage the asphalt, leading to premature deterioration and a range of other problems. If the driveway is not properly sloped, water can accumulate on the surface, leading to standing water and erosion. Additionally, wetting down the driveway can make it more slippery, which can be a safety hazard, especially if the driveway is steep or has tight curves.
When to Wet Down a New Asphalt Driveway
So, when should you wet down a new asphalt driveway? The answer to this question depends on a variety of factors, including the climate and weather conditions in your area, the type of asphalt used, and the age of the driveway.

In hot and dry climates, it may be necessary to keep the driveway wet for a longer period, potentially up to 72 hours or more, to prevent excessive drying and cracking.
It’s crucial to monitor the condition of your driveway and adjust your watering schedule accordingly. You can check the driveway’s moisture levels by performing a simple “footprint test”: if your footprints remain visible on the surface for more than a few minutes, it’s likely that the driveway is too dry and needs to be watered. On the other hand, if the surface is excessively wet or slippery, you may need to reduce the frequency or duration of your watering sessions. By paying close attention to the condition of your driveway and making adjustments as needed, you can help to ensure a successful curing process and a long-lasting finish.
What are the risks of not wetting down my new asphalt driveway?
Failing to wet down your new asphalt driveway can have several negative consequences, including premature aging and cracking. When asphalt dries out too quickly, it can become brittle and prone to damage, which can lead to costly repairs and maintenance down the line. Additionally, a dry and cracked driveway can be unsightly and detract from the overall appearance of your property. In extreme cases, neglecting to wet down your driveway can even lead to structural problems, such as uneven settling or shifting of the asphalt surface.
To avoid these risks, it’s essential to prioritize wetting down your new asphalt driveway, especially during the critical curing phase. By keeping the surface consistently moist, you can help to ensure a smooth, even finish that will last for years to come. Furthermore, a well-maintained driveway can also enhance the overall value and curb appeal of your property, which can be a significant factor if you decide to sell your home in the future.
