Sealcoating is an essential maintenance technique used to extend the lifespan and enhance the appearance of asphalt pavements. Whether it’s a commercial parking lot, residential driveway, or a public road, sealcoating serves as a protective barrier against various damaging elements, including moisture, oils, chemicals, and UV rays. Andersen Asphalt & Striping would like to bring some clarity to the sealcoating process, outlining each step in detail and explaining how this preventive measure can safeguard your asphalt investment.
What is Sealcoating?
Sealcoating involves applying a protective coating to asphalt-based pavements to shield them from degradation caused by weather, traffic, and chemicals. The sealcoat material typically consists of a mixture of blended asphalt, water, mineral fillers, and various other additives. This mixture provides a layer that not only protects the asphalt but also fills surface damage and gives a refreshed, new appearance.
Benefits of Sealcoating
Before diving into the process, it is important to understand the benefits of sealcoating:
• Protection against oxidation from the sun’s UV rays.
• Enhanced resistance to oil and chemical spills.
• Prevention of water penetration, reducing the risk of potholes and cracks.
• Improved appearance with a rich, uniform color.
• Increased lifespan of the pavement, reducing long-term repair costs.
Asphalt Sealcoating Process
Step 1:Inspection and Evaluation – The first step involves a thorough inspection of the pavement to assess its current condition. Any structural damage, such as large cracks, potholes, or areas of crumbling asphalt, needs to be repaired before the sealcoating application.
Step 2: Cleaning the Surface – The success of sealcoating depends heavily on the preparation of the surface. The asphalt must be cleaned thoroughly to remove dust, debris, and stains. This is typically done using brooms, blowers, and, if necessary, pressure washing.
Step 3: Crack Filling – Cracks in the asphalt must be addressed prior to sealcoating. Crack filling involves using a rubberized crack filler that seals the cracks and prevents water from penetrating the asphalt’s base material.
Step 4: Application of Sealcoat – The sealcoat can be applied using a squeegee, brush, or sprayer depending on the size of the area and the specific product being used. The application must be even and comprehensive, ensuring that the entire surface is covered without pooling in any areas.
Step 5: Curing – After application, the sealcoat requires plenty of time to dry and cure. This typically takes around 24-48 hours under suitable weather conditions. During this period, the surface should not be used for traffic or walked on to ensure the sealcoat forms a hard, protective layer.
Step 6: Second Coat (if necessary) – Depending on the product used and the traffic conditions, a second coat may be applied to provide additional protection and ensure an even finish.
