Sealcoating helps protect asphalt surfaces from damage caused by UV rays, chemicals, and moisture. The process starts with cleaning the surface using a blower or pressure washer. Next, apply a crack filler to repair any existing cracks. Once dry, a sealcoat is applied using a driveway sealer sprayer or sealcoat sprayer. Let it cure for 24-48 hours before opening the area to traffic. Using professional-grade sealcoating equipment like a Graco line striping machine or an asphalt sealer sprayer ensures smooth, even application for optimal protection.
