Concrete Sealing and Coating Pricing: What Contractors Should Charge
Concrete sealing costs $1.50-$3.00 per sq ft for acrylic sealers and $3-$5 per sq ft for epoxy or polyurethane coatings. Penetrating sealers run $0.75-$2.00 per sq ft. A typical 600 sq ft driveway sealing costs $900-$1,800. Garage floor epoxy coating (400 sq ft) runs $1,200-$2,000. Resealing every 2-3 years creates profitable recurring revenue at $1.50-$3.00 per sq ft.
Concrete sealing and coating is a high-margin service that requires minimal equipment, creates recurring revenue, and pairs naturally with every new concrete pour. A single sealing job generates $500-$3,000 in revenue for 2-6 hours of work, and resealing every 2-3 years builds a loyal client base. This guide covers pricing for every type of concrete sealer and coating, from basic penetrating sealers to premium epoxy garage floor systems.
Concrete Sealer Types and Their Pricing
Concrete sealers fall into two categories: topical (film-forming) and penetrating. Acrylic sealers are the most common topical sealer, priced at $1.50-$3.00 per sq ft applied. Solvent-based acrylics ($0.20-$0.40/sq ft material cost) provide a high-gloss wet look and excellent color enhancement for stamped and decorative concrete. Water-based acrylics ($0.15-$0.30/sq ft) are lower odor and easier to apply but provide less color pop. Apply two thin coats with a roller or sprayer for best results. Polyurethane sealers ($2.50-$4.00/sq ft applied) offer superior durability and chemical resistance — ideal for garage floors and commercial applications. Penetrating sealers (silane, siloxane, siliconate) run $0.75-$2.00 per sq ft applied. They do not change surface appearance but protect against water, salt, and freeze-thaw damage — perfect for driveways and sidewalks in northern climates. Material costs for penetrating sealers range from $0.10-$0.30 per sq ft, making the profit margin exceptional at 60-75%.
Epoxy Garage Floor Coating Pricing
Epoxy garage floor coatings are a premium service priced at $3-$8 per sq ft installed. A standard two-car garage (400 sq ft) runs $1,200-$3,200. The process includes: floor preparation (grinding or acid etching) at $1-$2 per sq ft, crack and spall repair at $0.50-$1.00 per sq ft, primer coat at $0.30-$0.50 per sq ft, epoxy base coat at $0.50-$1.00 per sq ft for material, decorative flake broadcast at $0.25-$0.50 per sq ft, and clear polyurethane or polyaspartic topcoat at $0.40-$0.80 per sq ft. Labor runs 6-10 hours for a two-person crew on a standard garage. The total material cost is $1-$3 per sq ft, with labor and overhead adding $2-$5 per sq ft. Present tiered options: basic solid-color epoxy ($3-$5/sq ft), flake-broadcast epoxy with clear coat ($5-$7/sq ft), and metallic or premium polyaspartic system ($7-$12/sq ft). Garage floor coatings are highly marketable — homeowners search for this service online at high rates, and before-and-after photos drive strong referral business.
Surface Preparation: The Key to Coating Success
Surface preparation accounts for 50% of coating success and should be 30-40% of your total project cost. For sealing, power washing at 3,000+ PSI removes dirt, oil stains, and loose material. For epoxy and polyurethane coatings, diamond grinding is the gold standard — it profiles the surface to 50-100 CSP (concrete surface profile), removes existing coatings, and opens the pores for adhesion. Grinder rental runs $200-$400 per day; owning a walk-behind grinder ($3,000-$8,000) pays for itself after 5-10 garage floor projects. Acid etching is a lower-cost alternative at $0.30-$0.50 per sq ft but provides inconsistent results and is not recommended for high-performance coatings. For severely contaminated surfaces (oil-soaked garage floors), degreasers and multiple grinding passes may be needed, adding $1-$2 per sq ft. Moisture testing is essential before applying any topical sealer or coating — use a calcium chloride test ($15-$25 per kit) or plastic sheet test. Moisture vapor transmission above 3 lbs per 1,000 sq ft per 24 hours will cause coating failure. Address moisture issues before coating, not after.
Building Recurring Revenue from Resealing
Resealing is the most profitable service in concrete work on a per-hour basis. Acrylic sealers on driveways and patios need reapplication every 2-3 years. A 600 sq ft driveway resealed at $1.50-$2.50 per sq ft generates $900-$1,500 in revenue for 2-3 hours of work (light cleaning, one coat of sealer). Material cost is $0.15-$0.35 per sq ft, giving you 75-85% gross margins. The key is building a resealing database — track every sealing job with the date, sealer type, and next recommended service date. Contact clients 2-3 months before their sealer is due for renewal. A concrete contractor with 200 sealed driveways and patios in their database generates $60,000-$100,000 in annual resealing revenue with minimal marketing cost. This recurring revenue stabilizes cash flow during slow months and provides crew employment between larger projects. Stamp out the initial sealing by including it in every new concrete proposal at a competitive rate — the long-term resealing revenue more than compensates for any initial margin reduction.
Decorative Concrete Coating Systems
Decorative concrete coatings transform plain surfaces into premium finishes without demolition and repour. Metallic epoxy creates a stunning swirled, three-dimensional appearance at $8-$15 per sq ft — material costs run $2-$4 per sq ft, but the artistic application skill commands premium pricing. Quartz broadcast systems (epoxy with colored quartz aggregate) provide excellent durability and slip resistance at $5-$10 per sq ft, popular for commercial kitchens, pool decks, and showrooms. Polyaspartic coatings cure in 2-4 hours (vs. 24-72 hours for epoxy), allowing same-day return to service at $6-$12 per sq ft — the fast cure time justifies the premium over standard epoxy. Stamped concrete overlays applied over existing concrete run $6-$12 per sq ft and create the appearance of new stamped concrete at a fraction of demolition and repour costs. Each of these systems requires specialized training and materials, creating a competitive moat for contractors who invest in the skills. The customer base for decorative coatings skews toward higher budgets and design-conscious homeowners.
Commercial Sealing and Coating Opportunities
Commercial concrete sealing and coating offers volume and recurring contract revenue. Warehouse and distribution center floors require penetrating sealers or densifiers at $0.50-$1.50 per sq ft — a 50,000 sq ft warehouse floor generates $25,000-$75,000 in revenue. Retail and showroom floors need high-gloss polishing and sealing at $3-$6 per sq ft. Parking garage decks require traffic-bearing membrane coatings at $5-$10 per sq ft. Restaurant and food service floors need seamless, chemical-resistant epoxy or urethane systems at $6-$12 per sq ft. Commercial sealing contracts often include annual maintenance — recoating high-traffic areas and touch-up work at $1-$3 per sq ft. A single commercial maintenance contract for 10,000 sq ft at $1.50/sq ft generates $15,000 in annual recurring revenue. To enter commercial sealing, build credentials with 3-5 completed commercial projects, obtain manufacturer certifications for the coating systems you offer, and develop relationships with property managers and facility maintenance directors.
Frequently Asked Questions
Sealing a concrete driveway costs $1.50-$3.00 per sq ft for acrylic sealers and $0.75-$2.00 per sq ft for penetrating sealers. A typical 600 sq ft driveway runs $450-$1,800 depending on the sealer type. Resealing every 2-3 years costs the same or slightly less since surface preparation is minimal on previously sealed concrete.
