Prepping Your Driveway Before Applying Asphalt Coating

Clean the Driveway

Before you even think of coating your driveway with asphalt, it is essential to clean it as thoroughly as possible. This involves removing any weeds, moss, rocks, twigs, dirt, or any other debris that may prevent the asphalt from adhering correctly or weaken the surface in the long run. Begin by using a leaf blower or broom to sweep away all the loose debris on the driveway. Then, use a pressure washer to blast off stubborn dirt and grime, taking care not to damage the surface with too much force.

Repair Any Cracks or Damage

Your driveway may already be showing signs of damage such as cracks, potholes, or sunken areas. Applying asphalt on such damages only masks the problem and makes it worse. Instead, it is better to make the necessary repairs first before you seal-coat the driveway. Use a sealant or crack filler to fill in visible cracks and apply asphalt patching to depressions and potholes. For more severe damage, you should consider repaving the driveway. Otherwise, your attempts at restoring it will have wasted your time, money, and effort. We’re committed to providing an enriching learning experience.

Allow Sufficient Drying Time

Asphalt coating requires a dry and warm surface for optimal adhesion and curing. Even after cleaning your driveway and repairing any visible damage, you must give it sufficient time to dry completely. The drying period can take anywhere from a few hours to several days, depending on various factors such as humidity, temperature, and air circulation. Before applying the asphalt, ensure that the driveway is entirely free from moisture. You can test this by sprinkling a few drops of water on it. If it beads up and doesn’t evaporate, then the surface is not dry enough.

Apply a Bonding Agent

Although asphalt coating materials are designed to adhere to the driveway surface, it doesn’t hurt to provide some extra bonding. A bonding agent is a liquid that helps the coating stick tightly to the surface, reducing the risks of cracking or peeling. Apply the bonding agent with a sprayer, roller, or brush, following the manufacturer’s instructions and paying attention to the recommended coverage rate. Don’t do it in areas where the surface is still wet, damp, or dirty, as this will interfere with the bonding process.

Choose the Appropriate Coating

The type of asphalt coating you choose depends on various factors such as climate, traffic volume, and the condition of your driveway. The two main types of asphalt coatings are coal tar and asphalt emulsion. Coal tar is the older and more traditional option, more resistant to chemicals and abrasions, and more durable. However, it emits more harmful volatile organic compounds (VOCs) than asphalt emulsion, making it less eco-friendly. Asphalt emulsion, on the other hand, is water-based, dries faster, and easier to install. It is also more flexible and less likely to crack.
