Armorseal Tread-Plex typically costs about $80-$150 per gallon before tax, with the exact price depending on the Sherwin-Williams dealer, color, and purchase quantity. A professionally coated floor commonly totals $2.50-$6 per square foot when cleaning, surface preparation, and two coats are included; floor condition and labor are major cost drivers.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Tread-Plex, 1 gallon | $80 | $115 | $150 | Material price; confirm local availability |
| Coated floor, per sq ft | $2.50 | $4.00 | $6.00 | Contractor application, ordinary preparation |
| 500-sq-ft project | $1,250 | $2,000 | $3,000 | Estimate for labor and coating |
What Tread-Plex costs for a typical floor
For product alone, budget roughly $80-$150 per gallon, or about $0.20-$0.60 per square foot per coat at approximately 250-400 square feet of coverage per gallon. Coverage varies with concrete texture, porosity, application method, and the thickness applied. A porous or rough floor may use more coating than a smooth, sealed surface.
Many projects use two coats, so material can amount to about $0.40-$1.20 per square foot before primer, cleaning supplies, tax, or labor. A 500-square-foot floor may need around 3-4 gallons for two coats on a smooth surface, with extra allowance advisable for rough concrete and touch-ups. Assumptions: standard colors, two coats, ordinary concrete, and no major repairs. For a contractor-applied floor, preparation and labor usually cost more than the coating itself.
How coating, labor, and prep appear in a quote
Contractor estimates may bundle coating and application into one per-square-foot rate. Asking for separate line items makes it easier to compare whether the quote includes two coats, floor cleaning, repairs, and disposal.
| Quote item | Typical price | What changes the charge | Common billing unit |
|---|---|---|---|
| Tread-Plex coating | $80-$150 | Dealer, color, and quantity | Per gallon |
| Application labor | $1.25-$3.50 | Coats, layout, and access | Per sq ft |
| Cleaning and surface prep | $0.50-$2.00 | Oil, old coating, and concrete condition | Per sq ft |
| Equipment and supplies | $50-$250 | Floor size and preparation method | Per project |
| Concrete patching | $2-$8 | Repair depth and damaged area | Per sq ft repaired |
Labor may also be priced by time, often around $50-$100 per worker-hour, but many contractors quote by the square foot. A quote that excludes preparation or a second coat is not directly comparable to a complete two-coat estimate.
Why concrete coverage and coat count change the gallon total
Manufacturer coverage figures are estimates, not guaranteed consumption. A 1,000-square-foot smooth floor might require about 6-8 gallons for two coats, while rough, porous concrete could require more. At $80-$150 per gallon, that is roughly $480-$1,200 for coating alone, before waste or additional material.
Cracks, spalling, moisture, oil, and an existing coating can change the scope. For example, a floor requiring grinding or removal of a failing coating may add $1-$3 or more per square foot, depending on the method and debris handling. Confirm the quoted coverage rate and number of coats against the actual floor condition.
What floor preparation can add before application
Simple sweeping and detergent cleaning may be included in the installation rate. Oil removal, mechanical grinding, patching, or removing old paint usually costs extra because it takes time and may require specialized equipment. Small projects can also face a minimum service charge of roughly $300-$800 even when the square footage is limited.
Moisture issues may call for testing or additional treatment, while extensive concrete repairs can require a separate trade or product system. These costs are not automatically part of a Tread-Plex coating quote. Request a written description of the surface-preparation method and any repair allowances.
How long a two-coat Tread-Plex job takes
A crew may spend 4-10 labor hours on a straightforward 500-square-foot floor, including cleaning, edging, and rolling two coats. Larger or irregular spaces take longer; grinding or patching can add a day or more. Labor estimates vary with crew size and whether furniture or equipment must be moved.
Application time is not the same as return-to-service time. Drying and recoat intervals depend on temperature, humidity, ventilation, and product directions; traffic may need to wait longer than the surface feels dry. Ask the installer to state when the floor can be recoated and safely used.
How regional labor rates affect the installed price
Labor-heavy markets, including many large coastal cities, may run about 15%-30% above a national midrange estimate. Smaller towns and lower-cost regions can be roughly 10%-20% below it, though travel distance or a small-job minimum can erase that difference. Material prices also vary by local dealer and availability.
For comparison, a straightforward 500-square-foot application might be quoted near $1,500-$2,400 in a lower-cost market and $2,200-$3,500 in a high-cost metro if preparation is included. These are planning ranges, not fixed regional price lists. Compare local quotes with the same coat count, preparation, and repair scope.
Three floor sizes and their likely project totals
| Project scenario | Coating estimate | Installed estimate | Scope assumption |
|---|---|---|---|
| 250 sq ft utility room | $160-$450 | $625-$1,500 | Two coats, basic cleaning, minimum charge may apply |
| 500 sq ft workshop | $240-$600 | $1,250-$3,000 | Two coats and ordinary preparation |
| 1,000 sq ft commercial floor | $480-$1,200 | $2,500-$6,000 | Two coats, clear access, no major repairs |
The material estimates allow roughly 3-4, 6-8, and 12-16 gallons respectively, using smooth-surface coverage and a waste allowance. Rough floors or extra coats can increase those quantities. Small floors often have a higher installed cost per square foot because setup and travel are spread over less area.
How to lower a Tread-Plex floor quote without cutting coats
Move stored items and clear the floor before the crew arrives if the contractor permits it; labor for moving equipment can add substantially to a small job. Combine adjacent rooms or schedule multiple areas together to reduce repeated setup charges. Compare at least two estimates that specify the same preparation and coat count.
Buy only the quantity needed after confirming coverage and dealer return rules; opened coatings may not be returnable. Avoid paying for repairs or upgrades that are not needed, but do not skip cleaning, compatible preparation, or a required second coat to lower the initial bill. The most useful savings usually come from controlling the prep scope and avoiding duplicated mobilization charges.
