Oil Spot Primer is a highly effective solution for treating oil stained asphalt surfaces before applying GuardTop sealant. This primer seals and covers the petroleum stains, preventing them from seeping through the newly applied GuardTop sealant. It helps to improve the adhesion of GuardTop to the asphalt surface, creating a strong and durable bond that can withstand harsh weather conditions and heavy traffic. In addition, Oil Spot Primer is easy to apply and dries quickly, allowing for a fast and efficient application of GuardTop sealant. It is the ideal solution for any asphalt surface, including parking lots, driveways, and walkways that have been affected by petroleum stains.
