Maintaining the integrity and appearance of your driveway or parking lot requires applying the right sealer. A good blacktop coating protects the surface from weather damage, oil spills, and general wear, ensuring it stays durable and looking fresh for years. With several types of blacktop sealers on the market, it’s essential to understand which one is right for your specific needs.
Here’s a guide to help you choose the right blacktop sealer.
1. Assess the Condition of Your Blacktop
Before choosing a blacktop coating, it’s important to assess the current condition of your blacktop surface. If your driveway or parking lot has minor cracks, an asphalt emulsion or coal tar sealer can provide both protection and fill small gaps. However, for more extensive cracks or damage, you might need a filler-based sealer or crack sealant before applying the protective coating. If the surface is heavily worn or has substantial damage, you may need to repair the blacktop first.
2. Understand Different Types of Blacktop Sealers
There are several types of blacktop sealers, each offering specific advantages based on your needs:
Asphalt Emulsion Sealer: This is one of the most common sealers, made from a mixture of asphalt, water, and emulsifying agents. It provides a smooth finish and protection from weathering but is less resistant to oil spills and chemical damage.
Coal Tar Sealer: Known for its durability, coal tar sealers provide excellent protection against oil, gas, and chemical spills. It’s often used in high-traffic areas like parking lots. However, it can be a bit more expensive and has a strong odor during application.
Acrylic Polymer Sealer: Acrylic sealers offer UV protection and resistance to water, oil, and chemicals. These are more environmentally friendly and provide a glossy finish, but they can be more expensive compared to other options.
Fast-Dry Sealer: If you need your blacktop to be usable quickly after sealing, consider a fast-dry sealer. These sealers dry faster than standard ones and are ideal for high-traffic areas where downtime needs to be minimized.
3. Consider Your Climate
The climate in your region is a significant factor in determining which blacktop coating to use. For example, if you live in an area with harsh winters and freeze-thaw cycles, choose a sealer with flexibility and durability, such as an asphalt emulsion sealer or coal tar sealer. These types can withstand the expansion and contraction of the blacktop caused by temperature changes. In warmer climates with less severe weather, a standard asphalt sealer may suffice.
