Sealing
Seal coating asphalt is the process of applying a protective layer of sealant to an asphalt surface. This sealant helps to protect the asphalt from damage caused by UV rays, water, oil, and other elements. It also helps to restore the appearance of the asphalt by filling in small cracks and providing a smooth, black finish.
The seal coating process typically involves the following steps:
- 1 Preparation: The asphalt surface is thoroughly cleaned to remove any dirt, debris, and vegetation. This may involve sweeping, power washing, or using a blower.
- 2 Crack filling: Any cracks in the asphalt are filled with a crack filler material to prevent water from seeping into the base and causing further damage.
- 3 Patching: If there are any potholes or larger areas of damage, they are repaired and patched with asphalt patching material.
- 4 Application: The sealant is applied to the asphalt surface using a squeegee, brush, or spray system. It is spread evenly to ensure complete coverage.
- 5 Drying and curing: The sealant needs time to dry and cure, typically taking 24-48 hours depending on weather conditions. During this time, the surface should not be driven or walked on.
Seal coating asphalt is recommended every 2-3 years to maintain the integrity and appearance of the asphalt surface. It can help extend the lifespan of the asphalt and prevent costly repairs or replacement in the future.
