It also acts as a waterproofing agent helping to minimize the absorption rate of water as it lays upon the asphalt and helps to prevent seepage thereof from this rain and snow, thereby preventing the damage that occurs during thaw cycles when it gets warm, then suddenly freezes again, allowing water again to penetrate which again leads to cracks and more repairs and more money out of your pocket.
Sealcoating provides an attractive black surface that is ideal for painting lines and other markers on parking lots. Sealcoat is a dark, black colored material and when applied to asphalt, it helps attract more heat from the sun. The hotter the sealcoating on the asphalt gets, the more pliable it becomes, which helps it to withstand traffic without cracking.
Sealcoating leaves a smooth, clean surface ideal for sweeping, which lowers cleaning costs and for a driveway and gives your entrance a fresh and new look, similar to painting your home or business. Sealcoating fills surface voids, which reduces exposure to oxygen and UV rays and reduces the depth to which oil or gas can penetrate the asphalt. It acts as a waterproofing agent, minimizing the rate at which water enters the asphalt of your driveway or parking lot.
An ounce of Preventive Maintenance can reward you with savings of replacement costs. Sealcoating costs pennies per square foot compared to the dollars needed to repair or replace damaged asphalt. The intrusion of moisture into asphalt not only accelerates its deterioration it allows for cracks to expand, potholes to weaken around the edges and expand even more.
