The actual cost to seal your concrete driveway will depend on the type of concrete sealer used, the size of your concrete driveway, and whether or not you will be applying the concrete sealer or hiring a company to apply the concrete sealer for you.
Cost to Seal a Concrete Driveway with a Silicate Concrete Driveway Sealer
Silicate concrete sealers penetrate into the surface of the concrete where they chemically react to form calcium silicate hydrate (CSH) within the pores. Silicates are designed to increase the strength and density of the concrete, and reduce deterioration caused by weak concrete and surface abrasion.
Silicate Sealers: Armor S2000, Armor L3000
Silicate sealers typically cost less than $1.00/ft2 if you are applying the sealer yourself, and around $8-12/ft2 if you hire a contractor.
Cost to Seal a Concrete Driveway with a Water Repellent Concrete Driveway Sealer
Silane-Siloxane water repellent concrete sealers penetrate into the concrete where they chemically react to form a water repellent barrier within the pores. Water repellent sealers are designed to reduce deterioration caused by water absorption such as cracking, spalling, freeze thaw and salt damage, mold and mildew, staining, and efflorescence. Water repellent sealers work entirely below the surface and won’t change the look or color of the concrete.
Water Repellent Sealers: Armor SX5000, Armor SX5000 WB, Armor SC25
A second type of water repellent sealer will also work below the surface, but in addition to offering water repellency benefits, it also slightly darkens the color of the concrete to bring out any dull and faded coloring.
Wet Look Water Repellent: Armor WL550
Water repellent sealers typically cost less than $1.00/ft2 if you are applying the sealer yourself, and around $8-12/ft2 if you hire a contractor.
Cost to Seal a Concrete Driveway with an Acrylic Concrete Driveway Sealer
Acrylic concrete sealers are designed to enhance and protect concrete with a wet look, low gloss, or high gloss finish. They will leave behind a visible surface film that protects concrete against deterioration caused by water absorption and surface abrasion.
Solvent Based Acrylic Sealers: Armor AR350 Armor AR500, Armor AX25, Armor LV15, Armor LV25, Armor AG Brown Seal
Water Based Acrylic Sealers: Armor WB15, Armor WB25
Acrylic sealers typically cost less than $1.00/ft2 if you are applying the sealer yourself, and around $8-12/ft2 if you hire a contractor.
Other Costs to Seal a Concrete Driveway
The above costs include just the cost of the sealer to seal the concrete driveway. You will also need application tools, such as a commercial pump sprayer, gloves, a roller, and any other personal protective equipment. You will also want to take into consideration cleaning tools, such as pressure washer or pressure washer rental.
There are many benefits to sealing your own concrete driveway, and there are many benefits to hiring a concrete contractor. If you seal your own concrete driveway, it is done with your products, your way, and in your timeline. If you hire a concrete contractor, they will typically handle everything from concrete cleaning, to application, to clean-up. Which option is best for you depends on your preferences and your budget.
