Cost to seal a concrete patio

The average cost to seal a 10’x20’ size concrete patio is $250 to $600. Concrete patios and steps will crack if not sealed. The best sealers for a patio are polyurethane or a penetrating sealer for a matte finish. For high-traffic patios, pay extra for epoxy and avoid acrylics.

Cost factors to seal concrete

The following table shows the cost breakdown to seal concrete:

Cost to seal concrete
Cost factors Average cost per square foot installed*
Sealer material $0.30 – $1.75
Labor cost $0.70 – $1.25
Total cost installed $1.00 – $3.00

*For acrylic and polyurethane sealer types.

Cost factors include:

  • Size – Larger areas cost more to seal but have lower rates per square foot.

  • Prep & cleaningPressure washing costs $0.35 to $0.75 per square foot. Contractors must clean and dry the surface first for the sealant to bond to it.

  • Concrete condition

  • Number of coats – Areas more vulnerable to wear and tear like driveways need more coats than a basement.

  • Geographic location / travel fees – Metropolitan locations have higher labor costs than rural areas. Additional travel fees apply outside of regular service areas.

Concrete sealing FAQs

Is concrete sealing worth it?

Concrete sealing is worth it for the following reasons:

Adds a protective barrier surface on top of the concrete

  • Prevents cracks and stains

  • Adds scratch resistance

  • Protects against color fading from the sun

  • Repels all moisture

  • Makes it easier to clean up stains

  • Prevents falls with non-slip textured sealers

  • Discourages mold, mildew, and bacteria growth

  • Adding color to make old concrete look new

What happens if concrete is not sealed?

If concrete is not sealed, it quickly absorbs moisture, oils, and grease. Water freezing inside concrete causes more cracks, and oils can permanently stain concrete.

How long does concrete sealer last?

Acrylic sealers last 1 to 3 years on average. Epoxy or urethane sealers last 5 to 15 years. The total lifespan depends on the concrete-sealer type, quality, number of coats, and surface traffic.

When to seal concrete

The best time to seal concrete is in the spring or fall when the temperature remains 50° F to 80° F for 24 hours minimum. Old concrete must be completely dry before resealing.

  • Wait at least 30 days before sealing a new concrete driveway.

  • Wait 24 to 72 hours after staining before sealing.

  • Stamped concrete needs sealing every 2 to 3 years.

  • Liquid acrylic cure & seal coating is the only type that contractors can apply without waiting for new concrete to cure first.

How long after sealing concrete can you walk on it?

Most sealers take 12 to 48+ hours to dry before you can walk on it. The total drying time depends on the sealer type and local climate.

  • Choose a licensed, bonded, and insured company with 5+ years of experience.

  • Get copies of the contract and detailed estimate before work starts.

  • Avoid selecting the lowest quote as quality may suffer.

  • Don’t make the final payment until after the work is complete.
