Asphalt sealant protects and preserves asphalt surfaces from damage caused by sunlight, water, and ice. It can be made from viscous asphalt or coal tar, but asphalt-based products are more environmentally friendly. Before application, surfaces must be clean and cracks smaller than a quarter inch can be sealed. The sealant is applied in two layers and should dry for a full day before use. Sealing every three years is recommended for durability. Asphalt sealant can be purchased in hardware or home improvement stores.
Asphalt sealant is an elastic polymer blend used to seal asphalt surfacing surfaces. It is used to protect and preserve asphalt from oxidation due to exposure to sunlight. It also fills structural voids, prevents ice and water damage, and creates a smoother appearance.
Often referred to as a driveway sealant, the concentrate’s most common use is in the repair of asphalt driveways. While normally made from viscous asphalt, asphalt sealant can also contain coal tar. Coal tar sealants are sometimes preferred over asphalt sealants, but asphalt-based products are considered more environmentally friendly. They also present fewer health risks during use.
Before applying asphalt sealant, surfaces must be clean. Dirt, oil, sand or grease residues will inhibit product adhesion if not removed prior to application. Grease stains may also need to be scrubbed or scraped. If grease or oil saturation is high, the asphalt should be stripped and replaced rather than sealed.
Cracks smaller than a quarter inch can be sealed with asphalt sealant. Any larger voids must be repaired prior to the sealing process. Rough surfaces can often be treated by adding clean silica sand to some types of asphalt sealants.
To begin sealing your asphalt coating, you must follow the instructions on your asphalt sealant container. Waterproof sealant is usually poured directly onto the surface in wide horizontal lines. The application is usually done twice with a putty knife or broom to ensure a clean and continuous result. The first layer should be dry before starting the second layer.
If ridges occur during the application process, they should be smoothed out. Although drying time is typically three to four hours, the area should remain intact for a full day before it resumes its general use. Applications should be avoided altogether in cold or rainy conditions.
Accidents may occur during application. If the sealant gets spilled on an unpaved surface, it can be washed off with clean water. If the product has already dried, it can be removed with a petroleum solution.
Many experts and manufacturers recommend sealing asphalt facing structures every three years to promote durability and longevity. Most sealants come with a limited warranty that guarantees effectiveness during this or a similar amount of time. Asphalt sealant can often be purchased in a five-gallon pail from a hardware or home improvement store. Professional quality sealants can be purchased in larger quantities.
