Apart from surface prep, measuring the parking lot is one of the critical prerequisites in sealing it.
There are several tools you can use to measure a parking lot.
Discover how you can measure circular and flared areas of parking lots.
We all know that any asphalt pavement will develop cracks and other signs of damage as the years pass. But what if you can prevent them from forming and extend the life of your pavement for an additional ten to twenty years?
Prolonging its lifespan is possible when property owners seal their asphalt regularly!
When asphalt sealer is applied, it serves as an additional layer of protection to the pavement. It seals up those little cracks and prevents moisture from seeping deeper into the asphalt. This helps prevent the development of cracks and potholes.
Another benefit of asphalt sealing is that it blocks harmful UV rays from damaging your pavement.
To be clear, exposure to sunshine alone doesn't automatically damage your pavement. But frequent exposure to ultraviolet rays combined with heavy vehicular traffic and excessive moisture can contribute to crack and pothole development.
Are you planning to conduct some crack sealing and apply asphalt sealer to the parking lot? Then this pavement maintenance blog is for you.
But first things first. Accurately measuring up your parking lot prior to sealcoating is absolutely essential; the last thing you want is to run out of sealant halfway through.
Equally, ending up with barrels of asphalt sealer left over will make the job much more expensive than it needs to be.
Luckily, measuring a parking lot for sealcoating does not have to be a complicated task, and there are a variety of tools that can help you breeze through the process with ease.
Take a look at our step-by-step guide to measuring a parking lot ready for sealcoating!

First, gather all tools and materials for this project.
What you will need for measuring the area before sealcoating a parking lot:
These items will help you determine how many square foot the parking lot has and the amount of pavement sealer you need to purchase.
Clean the Parking Lot. Remove any debris, leaves, or loose dirt from the surface of the parking lot. This will help you take accurate measurements.
Divide the Parking Lot into Sections. Divide the parking lot into manageable sections. It’s easier to measure a large parking lot by dividing it into smaller sections, such as rows of parking spaces or islands.
Survey the parking lot and figure out what shapes are involved. Luckily, most parking lots are squares or rectangles, making measuring up incredibly easy work. However, some parking lots may contain circles, semi-circles or ‘flares’ around the edges.

Top tip
If you are unable to go out and physically measure the area or would like a quicker and more convenient option, our online tool can help you easily measure up your asphalt surface area using Google’s satellite technology.
Once you have figured out approximately how much area you are looking to cover, it’s time to decide how much parking lot seal (either asphalt emulsion, acrylic, or coal tar) you need.
Calculate the amount of sealcoat material needed. The amount of sealcoat material needed will depend on the type of sealcoat being used and the manufacturer's recommendations. Take a look at our handy sealcoating calculator for an accurate estimate.
We'll factor in the size of the area and the sealcoating method you will use. This is to provide you with an accurate idea of how many gallons of product you will need.
Usually, the sealcoat material is applied at a rate of 0.15 to 0.20 gallons per square yard.
You also have to consider the number of coats. Usually, two coats of sealcoat are recommended for a parking lot. So, double the amount of sealcoat material calculated in the previous step.
Finally, consider waste factor. It’s always good to account for some waste. Add 5-10% to the total amount of sealcoat material calculated to account for waste.
Remember to always check with the manufacturer of the sealcoat material for any specific recommendations or requirements.
Now that you're done measuring the parking lot, it's time to choose the right sealcoating tools and equipment.
AirBoss 300 Air-Operated Sealcoat Spray System - Pro

Sealcoating Straight Blade Squeegee
Features: A squeegee is a simple hand tool that consists of a flat, smooth rubber blade attached to a handle. The sealcoat material is poured onto the asphalt surface and then spread evenly using the squeegee.
Benefits: Using a squeegee allows for a thicker application of the sealcoat material, which can fill in small cracks and imperfections in the asphalt surface.
It also provides better contact between the sealcoat material and the asphalt surface, which can result in better adhesion and a longer-lasting sealcoat.
Suitability: Squeegees are suitable for small to medium-sized parking lots or for areas where precision is required, such as around edges, curbs, and manholes. They are also ideal for use on uneven surfaces where a spray system may not be as effective.
Wand Wizard Edger For Sealcoating
Features: Edgers are specialized tools designed to apply sealcoat material precisely along the edges of the parking lot, curbs, and landscaping.
They can be manual tools, similar to a squeegee but with a smaller, more precise blade, or they can be attachments for a spray system that allows for precise application along edges.
Benefits: Edgers allow for a clean, precise application of sealcoat material along edges, which can enhance the appearance of the parking lot and protect the edges from wear and tear. They also help to prevent overspray onto curbs, landscaping, and adjacent surfaces.
Suitability: Edgers are suitable for all sizes of parking lots, but they are especially useful for parking lots with a lot of curbs, landscaping, or adjacent surfaces that need to be protected from overspray.
Now that you know how to measure a parking lot for sealcoating, it's time to prep your asphalt pavement and apply sealer.
For many business owners, maintaining parking lots isn't just about functionality — it's also about presenting the best face to customers and clients. An asphalt parking lot that's been meticulously maintained adds significant curb appeal to a property.
One essential component of an effective parking lot maintenance or pavement maintenance program is parking lot sealcoating. Here's a step-by-step guide to help you ensure the longevity and appeal of asphalt surfaces.

Step 1: Inspection and Preparation
Evaluate the Asphalt Surface. Before sealcoating a parking lot, conduct a thorough inspection to identify signs of wear and tear. Check for cracks, potholes, or any surface deformities.
Crack Sealing. Address any cracks you find. Crack sealing is a preliminary step before sealcoating. It ensures the sealer will adhere properly and that existing cracks in any pavement surface or asphalt parking lots won't worsen.
Step 2: Cleaning the Surface
Remove Debris. Clear the lot of any debris, including leaves, twigs, and trash. This will ensure a smoother finish.
Step 3: Applying the Sealer
Mix the Sealer. Before applying to the parking lot, ensure the pavement sealer is mixed thoroughly.
Spray or Brush Application. Depending on the size of the parking lot and the tools you have, the sealer can be applied using a sprayer or a large brush. Spraying is more efficient for larger lots while brushing might provide a thicker coating.
Apply in Thin Coats. It's recommended to apply two thin coats rather than one thick one. This ensures even coverage and a more polished black finish.
Coverage Rate. On average, a gallon of sealer covers 100 square feet. Always check the manufacturer's recommendations for specific coverage rates.
Step 4: Drying and Curing
Allow Adequate Drying Time. After application, sealcoating parking lots requires a good amount of time to dry. Typically, a parking lot should be kept traffic-free for at least 24 hours after sealcoating.
Check Weather Forecasts. It's essential to conduct sealcoating when the weather is clear. Rain can wash away the sealer before it dries, compromising the integrity of the job.
Step 5: Maintenance and Care
Regular Inspection. Encourage the business owner to inspect the lot regularly for signs of wear or damage. Prompt attention to issues will extend the life of the sealcoating.
Reapply as Needed. Depending on the traffic and environmental conditions, sealcoating might be required every 2-3 years.
Sealcoating Tips from the Pros
Here are some expert tips and best practices for successful parking lot sealcoating.
1. Surface preparation is the most critical step in the process. Make sure to clean the asphalt thoroughly by using a regular broom, power broom, and blower. For oil stains, use an oil spot primer.
2. Repair all the cracks, potholes, and damaged areas of the asphalt before sealcoating. Use appropriate materials like crack filler or asphalt patch for repairs.
3. The day's temperature plays a significant role in the sealcoating process. Make sure the temperature is above 50°F (10°C) and below 100°F (38°C) during the application and for at least 8 hours after the application.
Moreover, ensure that there is no rain forecasted for at least 24 hours before and after the application.
4. Mix the sealcoat material as per the manufacturer's instructions. Proper mixing ensures a uniform consistency and better adhesion to the surface.
5. Use a brush for the edges to ensure a neat finish.
6. Allow the sealcoat to cure completely before opening the parking lot for traffic. It usually takes about 24-48 hours for the sealcoat to dry and cure completely.
7. Applying the sealcoat too thick will lead to an uneven surface, and it will take longer to dry and cure. Two thin coats are better than one thick coat.
8. Proper mixing of the sealcoat material is essential for a uniform consistency and better adhesion.
Now that you know how to measure and prepare a parking lot, it's time to start sealcoating.
