With time, moisture and exposure to the environment will naturally soak into the asphalt. Rains penetrate the surface, heat from the sun weakens the binding materials and liquid from vehicles slowly erodes the pavement surface. A quality sealcoat will help to shield the pavement surface from moisture ingress, reduce oxidation, and enhance the pavement surface’s appearance. This is why many property owners rely on Professional Parking Lot Sealers Corona to ensure long-lasting and durable asphalt surfaces in the face of frequent heavy traffic and weather conditions.
According to the Asphalt Sealcoat Manufacturers Association, sealcoating can improve the life of the pavement by double. This means that over time, the costs of maintaining the equipment are lower, and the full replacement costs are less. That mathematics is necessary for business homeowners who own big parking regions and wish reliable outcomes from Business Parking Area Sealers Corona.
What sealing actually does for your pavement
Asphalt is a permeable substance. Over time, water infiltrates, UV rays degrade the binder and oils from vehicles wear off the surface. A good sealcoat seals those pores, slows oxidation and makes the surface clean and even.
The Asphalt Sealcoat Manufacturers Association reports that sealcoating can double the lifespan of the pavement. This results in reduced full replacement costs and less cost over time. That math counts for commercial property owners who have large parking areas..
Types of sealers used on parking lots
Not every sealer performs the same way. Here’s a quick comparison:
| Sealer Type | Avg. Cost per sq ft | Durability | Best For | Maintenance Cycle |
| Coal tar emulsion | $0.14–$0.25 | High | Heavy-traffic lots | Every 2–3 years |
| Asphalt emulsion | $0.12–$0.22 | Moderate | Standard commercial | Every 2–4 years |
| Fast-dry acrylic | $0.18–$0.30 | High | Airports, retail | Every 3–5 years |
| Gilsonite-based | $0.20–$0.35 | Very high | Sun-exposed surfaces | Every 4–5 years |
Sealers based on Gilsonite or acrylic sealers may be recommended for Corona’s harsh summer weather , low humidity and freeze-free environment because they offer better resistance to UV rays, vehicle traffic and water penetration. Hiring a professional parking lot sealer in Corona means choosing a solution that’s best suited for the pavement’s condition, the amount of traffic it receives, and its future maintenance requirements.
The sealing process, step by step
Being informed about what a contractor should do will enable you to identify the professionals from the cut price crews.
First, the lot is cleaned: any debris is blown off, loose material is removed from any cracks with wire brushing and oil spots are removed with a degreaser. This is one of the more common “short cuts” and is a sure recipe for early peeling.
Then cracks are filled in. Before the application of sealer, hot-rubber or cold-pour crack filler is required in any crack opening greater than a ¼ in width. Covering up open cracks only keeps moisture under cover.
Next, the application of sealer coats (usually two) by squeegee or spray, under conditions of surface temperatures above 50°F with no rain in sight for at least 24 hours. The crews begin in the morning to minimize the application of the sealer on surfaces more than 90°F in Corona’s summer heat to prevent bubbling.
Last but not least, the lot dries. Most commercial sealers require 24-48 hours prior to vehicle traffic. Reduces business disruption for retail or medical properties with some fast-dry acrylics ready in 6-8 hours.
The amount of money it takes in Corona
What it costs in the Corona area
The average price of corona parking lot sealing is $0.15 to $0.35 per square foot. The type of sealer used, the condition of the parking lot, and the size of the crew will influence the cost of parking lot sealing services. The price in this case could be $1,500 to $3,500 for a 10,000 SF commercial lot with full service (crack filling and two coats).
Bids that are 40% below market price may represent one coat, very little (or no) crack preparation, or a very diluted sealer. The EPA’s pavement and seal coat guidance states that if coal tar emulsions are used incorrectly, they can increase the amount of Polycyclic aromatic hydrocarbons (PAHs) in the runoff, potentially causing non-compliance with the California water quality regulations.
How to choose the right asphalt sealcoating contractor
So what makes a good professional different from someone taking you a lot of money and leaving you with a surface that is peeling in six months?
Request proof of California contractor licensing (Class C-32 for parking area marking, or Class A for general engineering.) Most general handymen don’t have the specialty coverage needed to protect commercial asphalt pavement — and if a handyman gets hurt while working on your property without insurance, you could be the one who is responsible.
Inquire about the way that they treat oil-stained areas. The sealer will not adhere to oil. If a contractor doesn’t have a clear answer to this, he/she hasn’t considered your lot conditions.
Always request a written spec sheet with the brand of sealer and dilution ratio as well as the number of coats. This is a service that a good asphalt protection company will offer without question.
A general contractor doesn’t monitor California compliance issues such as stormwater requirements and local permit specifications for lane striping, as does the company specializing in commercial parking lot sealing in the Inland Empire (Inland Empire Companies).
Conclusion
Once you are ready to proceed, a surface assessment makes sense — it lets you know whether or not you need to have crack repair, patching, or a straight two coat seal.

FAQ’s
The typical lifespan for seal coating asphalt on commercial lots with high usage is every 2 to 3 years. Some Lots may require attention more frequently than every two years due to heavy truck use and/or high UV exposure.
Expect to pay $0.15 to $0.35 per square foot. The price for a mid-size commercial lot (15,000 sq.ft.) ranges from $2200 to $5000, depending on the type of sealer used, and the preparation necessary on the surface.
Seal coating alone typically doesn’t require a permit in Corona. If the traffic flow patterns are different or the restriping is required, the City of Corona’s Public Works department may need to review it. Make sure with your contractor before you start work.
Surface blistering can occur when sealers dry too fast, due to high surface temperatures over 90°F. Professional asphalt sealers plan to work in the mornings in the summer months and keep track of surface — not air — temperature before sealing.
Seal coating is a protective coating that is applied to existing pavement. Resurfacing involves adding a new layer of asphalt. Sealcoating will not repair base failure or cracking caused by alligators.
Yes. Highly skilled parking lot maintenance professionals work in stages, perhaps half a lot a day, to keep all businesses up and running, while still maintaining the lot.
