Approximately 400 sq. ft. can be covered by one gallon of sealer.
You can walk on the asphalt after 2 hours, but it is recommended not to drive on it for 24 hours.
Sealcoating is a protective measure for asphalt that can extend its lifespan. A general guideline is to apply seal coating every 1 to 2 years, which maintains a consistently high level of protection for the asphalt, thus ensuring it lasts longer.
The recommended temperature is 60 degrees Fahrenheit.
The cost can differ, but typically it is 18 cents per square foot.
Preparation of cracks before the repair is essential. Before they become severely damaged, crack filling can be an economical approach for preventive maintenance of asphalt pavement. The primary objective of preparing a crack is to create a dry and clean reservoir area, allowing the sealant to stick to the crack walls. The crack should be cleaned using a wire broom or wheel, ensuring a sufficient reservoir is created. Then, fill the crack with either hot or cold pour material and use a squeegee to smoothen any excess material. With a proper and timely filling, the functional lifespan of an asphalt pavement can be extended for several years.
When working in this area, it is crucial to use a blocker board. Position the board against the edge nearest to the house and ensure that you only spray the length of the board. Move the board along and continue spraying until you reach the end. This technique will prevent any accidental spraying of sealer on the building. This process is known as cutting the driveway and requires careful attention.
The application is achieved by coordinating the movement of the spray wand. You will become proficient in using various motions to adjust the spray pattern and coverage rate. The height of the spray wand also impacts the application. A higher wand position produces a lighter spray, covering a broader area. A lower wand position creates a narrower pattern and applies a thicker coat. Additionally, the speed at which you move the wand determines the amount of sealer applied. It is crucial to keep the wand in motion continuously.
An oil spot primer is an effective treatment for most oil spots, as it creates a barrier between the oil spot and sealer, allowing the sealer to adhere to the asphalt. Begin by cleaning up the oil as much as possible using an absorbent material. Next, apply the primer onto the oil spot and let it dry for approximately 1 to 2 minutes.
