Sealing your concrete can cost between $850 and $7,000, with most homeowners spending $1,500 or $1.35 to $2.50 per square foot. Factors like your location, the size of your concrete area, and the quality of materials will affect the total cost. Regularly sealing your concrete every two to three years is important for maintenance, so it's wise to budget accordingly and consider hiring a professional. By hiring a local concrete sealing pro, you can ensure quality results that protect your investment.
Cost to Seal Concrete per Square Foot
Sealing your concrete yourself costs between $0.10 and $0.75 per square foot for materials alone. If you hire a professional concrete sealer, you can expect to pay $1.35 to $2.50 per square foot, depending on the type of sealer and the specifics of your project. Whether you're sealing a small concrete pad, backyard patio, or entire driveway, knowing the cost per square foot can help you budget for the price to seal them.
| Concrete Size (Sq. Ft.) | Average Cost Range |
|---|---|
| 50 | $65–$150 |
| 100 | $135–$250 |
| 250 | $335–$650 |
| 500 | $625–$1,250 |
| 1,000 | $1,350–$2,500 |
Concrete Sealing Cost Factors
Several factors impact the overall cost to seal concrete, including the size of your concrete slab, how much preparation is needed before sealing, the type of sealer you purchase, and the number of coats you need to apply.
Size
Sealing concrete costs as little as $0.10 per square foot for materials, but with labor included, prices can run up to $2.50 per square foot. Most concrete contractors provide an estimate based on the size of the area that needs sealing. Naturally, larger projects come with higher overall costs.
Preparation and Cleaning
Proper cleaning is essential before sealing concrete to ensure a smooth, lasting finish. While you can power wash the concrete before the project begins, most professionals will use specialized cleaning solutions to remove deep stains, oil, and debris for better adhesion. They may also use mechanical methods, such as scrubbing or etching, to prepare the surface. The more prep work your concrete requires, the higher your labor costs will be.
Number of Coats
The number of coats required for concrete sealing can significantly affect the project's overall cost. Many sealing products recommend applying more than one coat for added protection, especially in high-traffic areas like driveways and garages. Applying multiple coats will increase the cost of materials and labor, as you’ll need additional products and more time for the application process.
Concrete Sealer Cost by Type
There are three major types of concrete sealers: acrylic, polyurethane, and epoxy. Each material gives your concrete a different look and finish, so it’s important to consider which type is best for your project during the planning phase.
| Type of Sealer | Average Cost Range per Gallon |
|---|---|
| Acrylic | $16–$75 |
| Polyurethane | $25–$110 |
| Epoxy | $40–$175 |
Acrylic
Acrylic concrete sealer is the least expensive option, costing just $16 to $75 per gallon. While it's a more basic option, acrylic is budget-friendly, dries quickly, and comes in various finishes.
Polyurethane
Polyurethane concrete sealer is very close in price to acrylic, averaging $25 to $110 per gallon. However, polyurethane is much thicker, making it more durable. This type of sealer is a great option for areas in your home with a lot of foot traffic and locations where the climate changes with the seasons.
Epoxy
Epoxy concrete coating costs $40 to $175 per gallon on average and is the most expensive option. However, epoxy has a high-gloss finish you can't achieve with other concrete sealing materials. Epoxy is commonly used for interior concrete, such as garage or basement floors. If the glossy look is what you prefer, it may be worth paying more for epoxy to get the finish you're looking for.
DIY vs. Hiring a Concrete Sealing Pro
While sealing your concrete may seem like a manageable DIY project, leaving it to the professionals is best. Stealing concrete is a time-consuming process that requires specialized tools and equipment. Professional concrete sealers can assess your concrete’s needs to choose the right sealer for the surface and apply it evenly for lasting results. They also have the experience to handle common challenges like uneven surfaces or the need for multiple coats. By hiring a concrete sealer near you, you’ll save time and avoid the risk of costly mistakes.

Frequently Asked Questions
Sealing is worth the cost because it prevents stains and keeps your concrete in good condition for longer. Considering that new concrete costs $125 per cubic yard on average—and concrete removal isn't cheap if you need to replace it—using a sealer helps protect your investment long-term. Sealing allows your concrete to better withstand the elements and heavy use, extending its lifespan and enhancing its appearance.
If you don't seal your concrete, the surface can become brittle and damage sooner. This damage is especially problematic in cold climates where frozen water can seep into the porous surface of unsealed concrete and expand, potentially causing cracks. Salt used for melting ice can also damage unsealed concrete more than it would sealed surfaces.
Concrete sealers last five to 10 years for epoxy and polyurethane products, while acrylic options last two to three. These sealers maintain their protective quality when applied under proper conditions. To ensure your surfaces remain well-protected, inspect them every two years, especially those prone to heavy use and environmental exposure.
Topical and penetrating sealers serve different functions for protecting your concrete. Topical sealers form a hard, visible film over the surface to block water, oil, and stains, while penetrating sealers bond chemically with the concrete to enhance durability from within without changing its natural look. The better choice between these two depends on the level of traffic, environmental exposure, and the finish you wish to achieve for your concrete.
