Your asphalt driveway or parking lot is constantly under attack, from blazing sun, pounding rain, and harsh automotive fluids. Over time, these elements cause asphalt to crack, fade, and deteriorate, leaving you with costly repairs or even full replacement. That’s where sealcoating comes in. This simple yet powerful maintenance service acts as a protective barrier, keeping your pavement strong, smooth, and looking fresh for years. Today, we at Andersen Asphalt & Striping would like to share how sealcoating shields your asphalt from the three biggest enemies: sun, water, and chemicals.
Protection from the Sun’s UV Rays
Asphalt is made from a combination of stone aggregate and a binding material called bitumen, which is derived from crude oil. When exposed to constant sunlight, UV rays break down the bitumen that holds the asphalt together. This process, called oxidation, causes the pavement to become brittle, lose its rich black color, and eventually develop cracks.
Sealcoating adds a dark, UV-resistant layer over the surface, much like sunscreen for your driveway. This coating blocks harmful ultraviolet rays and slows the oxidation process, keeping the asphalt flexible and resilient. As a bonus, the dark finish absorbs heat evenly, helping snow and ice melt faster in the winter months.
Defense Against Water Damage
Water is one of asphalt’s greatest threats. When moisture seeps into tiny cracks or pores in the surface, it can cause significant damage, especially when temperatures drop. Water expands as it freezes, forcing cracks to widen and creating potholes over time. Even in warmer climates, standing water can erode the sub-base beneath the pavement, leading to soft spots and uneven surfaces.
Sealcoating forms a waterproof barrier that prevents rain and melting snow from penetrating the asphalt. By sealing off these entry points, it reduces the risk of freeze-thaw damage and extends the lifespan of your pavement. Proper drainage and regular maintenance combined with sealcoating can add many years to your driveway or parking lot’s service life.
Resistance to Chemicals & Oils
Asphalt surfaces, especially in high-traffic areas, are frequently exposed to automotive fluids like oil, gasoline, and antifreeze. These chemicals can dissolve or weaken the asphalt binder, leading to soft spots, surface breakdown, and unsightly stains. Once these contaminants soak into unprotected pavement, they’re nearly impossible to remove completely.
Sealcoating creates a non-porous, chemical-resistant surface that repels these fluids. Instead of soaking in, spills stay on the surface, making cleanup faster and easier. This not only keeps your pavement looking cleaner but also helps maintain its structural integrity.
Protecting Your Investment
Sealcoating is one of the most cost-effective ways to preserve your asphalt. A professionally applied sealcoat every two to three years can double or even triple your pavement’s lifespan compared to untreated surfaces. It enhances appearance, prevents premature aging, and saves you from expensive repair bills.
