When should you repave a parking lot. Let’s look at indications that you should repave a parking lot. Are you looking at your parking lot wondering how you are going to fix the damage? How you are going to make it more appealing? Are you trying to decide if you can wait to have your lot repaved and/or touched up? This article will help you better understand your parking lot.
Your parking lot is the first impression of your business. There are several ways to enhance the beauty of your lot and to ensure any potential liabilities are
addressed in a timely manner.
When Should You Repave a Parking Lot
Let’s begin with the basics- when your lot is initially paved you can expect the lifespan to be approximately 15-20 years. Over time nature, gasoline, oil, and other products of the like will break down components of the asphalt. As soon as you notice cracking in your lot, our best advice is to have it filled.
This will prevent further damage and costly repairs. See the table above (Good Pavement) for examples of cracks that should be filled. Cracks within the pavement that are ¼” or greater should be filled. This process consists of injecting the crack with a rubberized material that will ensure the pavement does not continue to expand and contract. If cracks are ignored and not filled, you run the risk of your parking lot alligatoring. Alligatoring happens when cracks continue to spread throughout the entire lot- at which point you would need to have an overlay done or complete repave. An overlay consists of applying a new layer of asphalt over the existing asphalt surface. The thickness of an overlay should range from 1.5” to 2”. If your parking lot needs to be graded, or if the grades need to be changed, then the project will require milling. Milling is the process by which a machine is used to plane the pavement surface to an appropriate depth before it is covered with the new layer. Once the milling is finished and the overlay is complete, the customer is left with a brand new surface, ready for pavement
Parking lots should be sealcoated every 2 years. Sealcoating does three things for your parking lot: it protects it, beautifies it and ultimately saves you money. Sealcoating gives your lot a sleek black finish, which will enhance the appearance of your property.
Is it better to use a sprayer or a squeegee to apply sealcoating? The debate began as soon as the first mechanical sprayer was invented. There is no definitive answer — an experienced, conscientious sealcoating professional can obtain quality results using either method or a combination of the two methods. Each has its own advantages and potential drawbacks.
How to Apply Sealcoating: Squeegee vs. Spray – Advantages and Disadvantages
• Squeegee applications typically produce a better bond between the pavement’s surface and the sealant. The pressure exerted by the squeegee forces the sealant into surface cracks and voids, creating a bond that is of higher quality while often yielding a smoother appearance.
• Sprayers provide better control of the amount of sealant used, making the application process more precise.
• Squeegee machines take a little longer than sprayers, but hand squeegees are the most timeconsuming.
On many jobs, it will take twice as long for workers to apply sealcoating by hand. Because weather conditions play a significant role in drying time, if the weather is cool, the crew may not have time to apply the second coat on the same day.
• Spray methods usually work better if the pavement is smooth and free from surface voids. As already noted, if there are voids, the sealant can be forced into them with a squeegee, but if there are no voids, the squeegee may glide too easily over the surface and leave too little sealant behind.
• Squeegees can leave behind too much sealant if the surface of the pavement is coarse. This can
lead to patches that take longer to cure as well as a finished surface that is less attractive.
Apply Sealcoating with a Combination Method
Many contractors find that they obtain better results if they apply the first coat by hand around buildings and sidewalks, use a squeegee machine or hand tools to apply the balance of the first coat and then use the spray method for the second coat. The squeegee method creates the superior bond, but it can leave slight imperfections such as tiny holes. These minor flaws can be eliminated when the spray method is used for the second coat.
Other Considerations When You Apply Sealcoating
Many problems reported for the different methods are due to an inexperienced operator or unethical contractor rather than the result of the method chosen. For example, a novice worker might leave behind noticeable lines when using a hand squeegee, a disreputable contractor might order the sealant to be thinned excessively or an inexperienced operator might set the spray rate too low. Your best bet is to find a reputable, experienced sealcoating professional and then trust his judgment on the best method or methods to use for your project.

We are often approached about whether or not coal tar based parking lot sealcoating is toxic. There have been several articles written condemning these sealants stating they are hazardous and should not be used. We are going to try to dispel these myths for you.
Parking lot sealcoating applies a protective coating that works much like paint protects wood, metal and other surfaces. The tar based parking lot sealcoating applied to the pavement surface protects the asphalt binder from degradation caused by sunlight, chemical attack and water intrusion. Seal coating provides an added benefit because it is formulated to also provide wear resistance to vehicular traffic.
We use coal tar based pavement sealers to sealcoat parking lots. These sealers are made from a selectively refined fraction of crude oil. Recent claims describing sealers as “toxic waste” have been circulating online and in the press.
Why do some people claim parking lot sealcoating is toxic?
These sealants are under scrutiny because they contain PAHs (Polycyclic Aromatic Hydrocarbons). However, PAHs are everywhere. Sources include grilled, roasted, baked and fried foods, as well as bread, cereal, grain and certain vegetables. The USDA allows over-the-counter-sales of shampoos and ointments that contain coal tar to treat dandruff, eczema, psoriasis and dermatitis.
Neither OSHA nor the EPA classifies coal tar-based sealants as being hazardous. Independent studies have repeatedly concluded that coal-tar sealants pose little risk to health or the environment, particularly because they are INSOLUBLE in water, which means living organisms can’t easily absorb them.
There is no scientific data that these products are hazardous or carcinogenic and we are confident that our employees are not at risk during the application process.
Driveways and especially large retail parking lots are capital investments that increase the value and
functionality of a property. Proper maintenance can extend the life of asphalt surfaces by as much as 300 percent. Sealcoating is still the best way to protect Pavement and is certainly a safe way to do it.

This article explores the top 5 Reasons to Sealcoat Your Parking Lot. First impressions are everything. New asphalt surfaces that are seal coated within their first year will experience less degradation from UV damage, water and traffic.

5 Reasons to Sealcoat Your Parking Lot
What impression is your parking lot making? 52% of consumers have avoided a business altogether because it looked dirty from the outside. 95% say that appearance is an important factor in selecting a place to shop.
(2) Prevent Oxidation
By blocking the sun and ultraviolet rays from damaging the surface causing cracks and deterioration.
The number one destroying force to asphalt pavement is WATER.
(4) Protecting Against Spills
Protect against gasoline oil spills from automobiles that damage and soften the surface.
(5) Preserve Your Investment
Properly applied, sealcoat can save an owner huge costs over the life of a hot mix asphalt pavement.
