Concrete is a widely used choice by many homeowners. It is used in projects such as sidewalks, driveways, patios, etc. Concrete cleaning and sealing are important to maintain the concrete for the long term. But how much does it cost each time?
This guide will help you calculate the average cost to clean and seal concrete. We’ll identify how much it costs for each project. Also understand the cost of each type of concrete sealer, so that you can choose the best for you.
Average Cost to Clean and Seal Concrete
The average cost to clean and seal concrete can vary between $2 to $5 per sq ft. Concrete sealer costs $30 to $80 per gallon. The cost to seal the concrete depends on the type of sealer material. Epoxy or poly aspartic sealants cost $4.00 – $10.00 per sq ft, up to 3 times more but last the longest.
However, these are just rough estimates. The total cost to clean and seal concrete depends on the local material and labor rates.
Cost to Clean and Seal Concrete by Size
See the table below to understand how much your project costs you according to size in square feet.
Size Sq Ft |
Average Cost |
| 50 | $50 – $450 |
| 100 | $100 – $900 |
| 150 | $150 – $1,350 |
| 250 | $250 – $2,250 |
| 500 | $500 – $4,500 |
| 750 | $750 – $6,750 |
| 1000 | $1,000 – $9,000 |
Different Types of Concrete
Polyurethane
Polyurethane sealers create a strong, durable layer on concrete surfaces. They are great for high-traffic areas like driveways and garages. These sealers resist stains and scratches well, but they need proper ventilation during application.
Acrylic
Acrylic sealers are popular because they dry fast and are easy to apply. They provide a thin protective layer on concrete and enhance its color. Acrylic sealers work well on indoor and outdoor surfaces, though they may need reapplication over time.
Epoxy
Epoxy sealers are tough and create a glossy finish. They are often used in garages and basements to resist stains, oil, and chemicals. However, epoxy can become slippery when wet, so some may add anti-slip additives during application.
Elastomeric
Elastomeric sealers are flexible and can expand or contract with the concrete. They are perfect for surfaces that may crack due to weather changes. These sealers also provide a waterproof barrier, making them ideal for outdoor concrete.
Penetrating Sealers
Penetrating sealers soak into the concrete, protecting it from within. They are ideal for areas exposed to water, such as pool decks, because they repel moisture. These sealers leave a natural look and don’t change the concrete’s appearance much.
Concrete Sealer |
Cost Per Sq Ft |
| Polyurethane | $1.25 – $3.00 |
| Acrylic | $1.00 – $2.00 |
| Epoxy | $4.00 – $10.00 |
| Elastomeric | $3.50 – $5.75 |
| Penetrating Sealers | $1.00 – $3.00 |
Note: This cost includes both material and labor costs.
Concrete Seal Cost of Multiple Projects
Concrete is used in multiple home projects such as driveways, sidewalks, pools, garages, etc. It is important to clean and seal the concrete to maintain it for a long period. Sealing the concrete with a sealer material creates an extra layer over the concrete. This layer protects the concrete from cracks and damage.

Additional Factors
Size:
The size of the project affects the cost of concrete sealing. Larger areas such as garages or pools cost more to seal as compared to countertops or patios.
Prep & cleaning:
It is necessary to clean the concrete before sealing. Pressure washing costs around $0.35 to $0.75 per square foot.
Concrete condition:
If the concrete is too old or in a bad condition, it will require more time and work to clean it. Thus the cost would increase.
Number of coats:
Areas that are more vulnerable to cracks or damage require more coats, such as driveways or sidewalks.
Location:
Lastly, the total cost to clean and seal concrete varies with location. The material and labor costs are different at different locations.
Conclusion
The average cost to clean and seal concrete can vary between $2 to $5 per sq ft. The cost to seal the concrete depends on the type of sealer material. Epoxy or poly aspartic sealants cost $4.00 – $10.00 per sq ft, up to 3 times more but last the longest. So, it is important to understand the features and costs of each type of sealer material before choosing the one.
Don’t forget to check the local labor and material rates to make an effective budget. Planning ahead can help you gain control over your expenses and do your project within your budget.
