Cost To Seal Concrete Driveway
Concrete is typically not sealed at all, and the natural weathering can add to its appeal. If you do choose to seal your concrete driveway, you can select between solvent and water-based acrylics. The cost to seal a concrete driveway with an acrylic spray-on cure and seal will cost about $0.53 per square foot. Two applications of a nonmetallic color and concrete hardener cost about $2.40 per square foot.
|Type||Material cost per square foot||Use & benefits||Appearance|
|Acrylic||$0.10 – $0.35||
|Epoxy||$0.10 – $0.20||
|Penetrating||$0.10 – $0.40||
|Polyurethane||$0.10 – $0.20||
Solvent-based concrete sealers are of a higher quality and are the most popular choice amongst homeowners. When you've made your decision, be sure the sealer is applied in thin coats with a sprayer or roller. This will allow the concrete to expand and allow moisture to escape properly.
Fixing holes, cracks, and spalling is required before sealing concrete. Concrete driveway repair costs $3 to $8 per square foot on average.
How Often Should You Seal Your Driveway?
Asphalt driveways usually need to be resealed every 3–5 years. The best time to reseal depends on the time of year and requires proper weather conditions for spotless results. Most experts recommend non-humid, warm, and dry conditions as optimal times to seal your driveway. Be sure to check the forecast so you can allow 2 or 3 days of dry weather for project days and drying days.
When Should You Seal A New Asphalt Driveway?
If your asphalt driveway is new, do not seal it. Wait until it has had at least six months to a year to cure and settle before any treatment or sealer is applied.
The cost to seal your asphalt driveway will probably increase each time you have it professionally done because the asphalt will have deteriorated more and will need more repair work before the new sealer is applied.
Concrete driveways are the most popular choice for homeowners because of their durability and longevity. It's best not seal concrete very often as resealing the driveway year after year can lead to hairline cracks and pealing. Contractors recommend concrete driveways should be sealed every four to five years to prevent water penetration and extend its lifetime. When cracking occurs, contact a concrete professional to determine if you need sealing, or if you have deeper foundational issues.
Sealing Asphalt Driveway – Pros and Cons
People can be opinionated about the need for sealer, but they lack facts to back it up. "Nobody has done long-term studies of sealer effectiveness." — Kent Hansen, director of engineering at the National Asphalt Pavement Association
- The driveway will almost look like new after adding a black sealer.
- Sealer prevents the asphalt from oxidizing and becoming brittle.
- Sealer prevents water getting into cracks and fissures in the asphalt, going through freeze-thaw cycles, and creating potholes.
- The sealer helps resist oil and gas stains from breaking down the asphalt.
- It’s an inexpensive job that only needs to be done every three years or so.
- If you seal too often, the layers of sealer can start to peel.
- Oil from the sealer can stick to shoes in hot weather and be tracked into the home.
- Some say that there’s no need for driveway sealer and that if your driveway starts to deteriorate, it’s because of a problem with the quality of the gravel base rather than the asphalt needing sealer.
Asphalt sealcoating vs. resurfacing
Asphalt resurfacing costs $1 to $3 per square foot and pours a new 1.5" to 2.0" overlay of asphalt over the old layer. Resurfacing adds 8 to 15 years to the asphalts lifespan.
All cracks and potholes must be patched before sealcoating or resurfacing a driveway. Asphalt driveway repair costs $2 to $5 per square foot on average.
Labor & Sealcoating Cost Per Square Foot
The labor cost alone will account for 50%–70% of the total price quoted. The average labor and materials cost to sealcoat asphalt is $0.17–$0.24/SF, which mostly varies based on whether the sealer is applied manually or with a sprayer and which sealer you want. Multiply this average cost by the square footage of your driveway, and you will have an estimated total price for your project, or 50% more than that if two coats are required.
Add on any additional costs if working with a slope on the driveway, have difficult access to the driveway, or if your driveway needs repair or crack sealer.
Slope of Driveway
Some manufacturers will not recommend adding a sealer to a driveway that’s too steep because of the sealer going on in liquid form.
If you’re sealing a driveway or area at the back of your property, it might require a lot of additional time and effort on the contractor’s part to get the right equipment back there, and you’ll be charged more for it.
Number Of Coats
Many contractors will recommend two coats to give your asphalt driveway stronger protection which lasts longer. However, expect to add 50% or more to your total price if two coats are required.
Size & Shape Of Surface Area
After labor costs, the second main cost of driveway sealing is the size of the area in square feet. The more square feet you have, the higher your price will be. If your driveway is an irregular shape, it may be harder to treat and require additional time and effort which will raise your final price.
Driveway Sealing Cost Calculator
To calculate the cost to seal your asphalt driveway, find the square footage of your driveway and multiply it by the price per square foot to sealcoat.
- Calculate the size of your of the driveway in square feet (length x width)
- Multiply square feet by labor and materials cost of approximately $0.21/SF
- Add 50% more if two coats are required, giving you the total cost of your driveway sealing.
Asphalt Sealing Costs By Use
It’s going to be exactly the same amount to seal any ground level asphalt per square foot. The only difference will be in how many coats are needed, which sealer is used, and the ease of access to the area that needs to be sealed.
|Parking Lots||$7,402–$10,454 per acre|
|Asphalt Patios||$100 minimum|
|Walkways or Pathways||$100 minimum|
|Basketball or Sports Courts||$680–$960|
Depending on the use, the majority of residential driveways only need one coat of sealer. The average two-car driveway is between 480 and 650 square feet which will help calculate the cost. Depending on the current condition and age of your driveway, you may pay extra for patching holes or other common repairs.
If sealing a commercial parking lot, it's recommended to use at least two coats of sealer. The cost to seal an asphalt parking lot is between $7,402 and $10,454 per acre which is approximately 43,560 square feet or roughly 150 parking spaces.
Asphalt Patios, Walkways, or Pathways
A typical asphalt patio or walkway has light foot traffic so it will only require one coat. The average patio is around 288 square feet and will cost $100 to $200 which is the typical minimum for a contractor to come out.
Basketball or Sports Courts
Depending on the size of your sports court, your price can vary dramatically. A full-size basketball court is 4,200 square feet, which is about 10-times more extensive than the average driveway and costs between $680–$960. A tennis court is more than half that size at 2,800 square feet.
- Roofing – to make roofing shingle more water-resistant
- Basements and foundations – to waterproof them
However, the sealer will come in a different product mix for these applications.
Types of Sealants
Coal Tar Emulsion
A water-based sealer. A byproduct distillate formed when coal is made into coke for the steel industry.
- Pros – The most durable sealer on the market, lasting approximately five years. Dries in 3–4 hours and will have set fully within eight hours. Resistant to UV rays, water, heat, motor oil, and gasoline. Not petroleum based. Can be applied with a sprayer system and comes ready to spray. Coal tar sealers must meet federal specifications. Lower cost than other sealers.
- Cons – Black-gray color. Minimum of two coats. Can’t be applied in temps below 50°F. Not eco-friendly.
Created because of the diminishing availability of coal. An asphalt sealer. Quality depends on the type of crude oil used in its manufacturing process and the refinery’s preferred method of blending.
- Pros – Restores asphalt to its dark black color. The next best choice for sealer. Tough against power steering marks. Eco-friendly and does not cause ozone pollution.
- Cons – Fades under UV rays and more susceptible to petroleum-based products, moisture, and high humidity. Doesn’t retain sand as well as coal tar sealer. There are no federal specifications for asphalt emulsion sealers. Dries more slowly and stays soft longer.
Latex Acrylic Sealer
- Pros – Fast drying times. Almost odorless. No need to premix if bought within a year of its manufacture date. Sprayable.
- Cons – More expensive. Not as durable as coal tar or asphalt emulsions, therefore not used or commercial applications. Contains carcinogens.
Latex Polymer Driveway Sealer
- Pros – Twice the durability of conventional coal tar emulsion. Superior resistance to wear, improved petroleum-based product resistance, stronger adhesion, and flexibility/elasticity. Ideal for high-traffic parking lots and driveways. No additional modifiers or latex additives required.
- Cons – More expensive. Can’t be applied in temps below 55°F or the film won’t form properly. Can expose you to chemicals including asphalt and crystalline silica, which are known to the State of California to cause cancer.
Some states have banned the use of refined coal tar sealers containing polycyclic aromatic hydrocarbons (PAH) because of potential harmful effects on the environment. Other eco-friendly sealers have been developed, including soy-based sealers used by some local and state highway departments. Check for approval stickers from NAHB (National Association for Home Builders), Ecologo Certification, and GREENGUARD Environmental Institute.
- Pros – The soy-based sealers have no PAH. Some of the products you can look at are soy based. Quick dry. Excellent chemical resistance, UV resistance, abrasion resistance, and adhesion to asphalt. Can be applied at room temps and doesn’t need to be heated. Low odor.
- Cons – Expensive

How To Seal A Driveway?
Your contractor has the right tools and materials to ensure the proper application of the sealer. Pay attention to manufacturer instructions regarding the tools required to seal your driveway if doing this yourself. The steps to take before applying driveway sealer are:
- Remove all dirt, debris, and weeds. Use a degreaser to remove any oil stains.
- Pressure wash the surface. Let it dry completely.
- Fill all cracks with elastomeric crack filler and smooth out with putty blade.
- Fill shallow eroded areas with trowel-grade crack filler and level them.
- Paint the driveway edges with the sealant mix by hand.
- Pour the buckets of asphalt sealer onto the pavement.
- Have a second person follow along and smooth the mixture out with a squeegee.
- Work from side to side with long strokes and cover each area twice.
- Let it dry and harden for at least 1 day.
1) Seal Driveway Cracks
Repair – About $30/hour plus materials. Your first step is to fill any cracks and minor holes, and repair deeper holes.
|Asphalt Repair Patch–For cracks up to one inch deep and a half inch wide||$5–$50 per tube, bottle, or bucket|
|Asphalt Pothole Fill||$10–$12 per 50-pound bag|
2) Clean Driveway
Clean - About $30/hour plus cleaning agents. Prepare the surface so that the sealer properly adheres to the existing asphalt; this involves trimming grass and plants from the edges, then sweeping, washing, and rinsing the area so that all petroleum-based spills like oil stains and gas are not on the asphalt before sealing.
|Pressure Washer Soap & Chemicals||$13–$14|
|Trimmer, leaf blower, push broom, cleaning brush, power washer, shop vacuum, water hookup|
3) Protect The Surrounding Area
Protect - About $30/hour plus materials. Your third step involves taping off edges—especially if they abut other surfaces such as concrete sidewalks or planters—and covering your garage door to protect against splatters.
|Surrounding Area Protection|
|Tape, gloves, protective eyewear|
4) Mix & Apply The Driveway Sealer
Mix – the sealer will need to be mixed and possibly heated before application.
|Sealcoat||$0.15 per square foot (single-coat)|
|Drill (to use with mixing paddle), buckets, 2x4 board|
The actual tools you need depend upon the size, age, and condition of your driveway, and the type of sealer you choose to use.
Driveway contractors will often add modifiers to a sealer. “Products like Black Beauty Sand add grit and improve durability. Sealmaster’s TopTuff and FSA increases sealer “toughness,” giving a blacker final product and greatly increases resistance to oil, fuels, and grease.” — DrivewayConceptsinc.com
DIY Driveway Sealing
While you can expect to save money by sealcoating your driveway yourself, it’s a huge risk to take considering how much you’ll spend on materials, tools, and safety precautions vs. the $100–$200 you could pay a contractor who has:
- Insurance, licensing, bonded
- Employees are given fair wages
- Professional equipment
- The experience needed to carry out repairs, mix the sealer properly, and spread it to the right thickness
DIY Driveway Sealing Costs
When comparing your time and money sealcoating your driveway to the time and expertise you’d pay a contractor for, you’d definitely lose if doing a DIY job on this one. Though labor accounts for about half of the final price, you’re only looking at about $50 to $80 in savings. Even then, you’ll probably have to spend more than that renting a power washer and/or spreader, making your final driveway sealing cost even higher than hiring a professional.
- Pressure washers: $62–90/day
- Sealcoat spreaders: $75/day
As you can see, the benefits of hiring a sealing professional far outweigh the cost of a DIY job.
Frequently Asked Questions
How Often Should You Seal Asphalt?
You should seal your asphalt driveway about every three to five years unless you live in an area with temps over 100° or with many freeze-thaw cycles, in which case reseal it every two to three years.
How Long To Stay Off Driveway After Sealing?
If your driveway was sealed between May and August, it's recommended to keep vehicles off for at least 48 hours. If you've sealed your driveway after August, stay off your driveway for at least 72 hours depending on the temperature. Driveway sealer may feel dry on the surface, but like paint, it may still be damp underneath.
What is an Asphalt Filler Sealer?
Asphalt filler sealer is a liquid compound that is brushed over an asphalt driveway and hardens to provide a more even surface and to prevent water from getting into cracks in the asphalt, which damages it over time.
What’s The Best Asphalt Driveway Sealer?
Based on reviews, the best asphalt driveway sealer is EnduraCoat Acrylic, with Goldstar Asphalt Sealer a close second.
How Can I Maintain My Coated Blacktop?
Fill any cracks that begin to appear with a crack filler mixed with sand and sealcoat it about every three years. Fix any oil or gas leaks in your vehicles to avoid spillage on the driveway. Pull up or kill any weeds. Check manufacturer’s instructions regarding the use of ice on your driveway—using it could damage the sealcoat.
Can A Concrete Patio Or Patio Be Sealed?
Yes, a patio can be sealed. We recommend using a solvent-based sealer to highlight the concrete's colors better. High-gloss sealers are slippery, and they block in the moisture which can cause fracturing, white hazing, or fogging.
Can You Seal Asphalt A Different Color?
Yes, many manufacturers have asphalt sealers in different colors, but they can cost from six to nine times more per gallon which is hardly worth the cost. The sealer can also be mixed with sand, which helps add traction back to an asphalt surface.
