Sealcoating asphalt is a preventative maintenance process that involves applying a protective liquid coating over an existing asphalt surface, such as a driveway or parking lot. This coating acts as a barrier against damaging elements like sunlight, water, oil, and chemicals that can break down asphalt over time.
Sealcoating is a cost-effective way to extend the life of asphalt, maintain its strength, and keep it looking clean, fresh, and well-maintained.
- Cleaning the surface
Dirt, debris, and vegetation are removed using powered blowers, brooms, or pressure washing to ensure proper adhesion of the sealcoat.
- Oil spot treatment
Areas contaminated with oil or fuel are treated with a primer or cleaner so the sealcoat can properly bond.
- Crack filling
Cracks are filled with hot rubber crack sealant to create a smooth, even surface and prevent further damage.
- Edge and surface preparation
Edges are defined and surrounding areas (like concrete or landscaping) may be protected to avoid overspray or spills.
- Mixing the sealcoat
The sealant is mixed to the proper consistency, often including additives like sand for durability and traction.
- Application of sealcoat
The sealcoat is applied evenly using squeegees, brushes, or spray systems to cover the entire asphalt surface.
- Drying and curing
The coated surface is left to dry and cure, typically for 24 depending on weather conditions.
- Applying a second coat (if needed)
A second layer may be applied for added protection and longevity once the first coat has dried.
