Sherwin-Williams Duration paint typically costs about $75-$105 per gallon at regular retail pricing, with sale prices or contractor discounts sometimes lowering the bill. The final price depends on the interior or exterior formula, finish, color, location, and how much surface preparation or labor the project needs.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Duration paint, per gallon | $65 | $90 | $110 | Retail estimate; formula and finish affect price |
| One gallon with supplies | $75 | $110 | $145 | Includes basic tools, not labor |
| Professional room painting | $350 | $750 | $1,500 | Room size, prep, and coats vary |
What one gallon of Duration paint typically costs
Duration Interior and Duration Exterior generally fall around $75-$105 per gallon at standard retail prices. A sale, coupon, or contractor account may bring the effective price to roughly $60-$85, while specialty colors or local pricing can push a gallon above $100. These are budgeting ranges, not fixed national prices; paint-store promotions change frequently.
Budget about $90 per gallon before tax for a typical retail purchase. A gallon often covers approximately 300-400 square feet for one coat on a smooth, previously painted surface. Porous surfaces, darker color changes, textured walls, and extra coats reduce coverage. A 10% waste allowance is reasonable when estimating quantity.
Assumptions: U.S. retail purchase, standard color, smooth prepared surface, and one-coat coverage estimates.
How paint, labor, and wall preparation shape the quote
A professional estimate may combine paint, masking materials, surface repairs, primer, and labor. The table gives broad project-level allowances; an estimate may itemize some of these costs or include them in a per-square-foot rate. Furniture moving, extensive patching, and difficult access can increase charges.
| Cost component | Typical price | What changes the charge | Example allowance |
|---|---|---|---|
| Duration paint | $75-$105 per gallon | Formula, finish, color, promotion | $180-$315 for 2-3 gallons |
| Labor | $30-$75 per hour | Region, crew skill, room condition | $300-$750 for 10 hours |
| Prep and primer | $50-$400 per project | Patching, sanding, stains, bare surfaces | $100-$250 for moderate repairs |
| Supplies and protection | $25-$125 per project | Drop cloths, tape, rollers, masking | $40-$90 for one room |
Paint is only part of a professionally painted room’s total expense. For labor budgeting, a basic estimate can use ; for example, 10 hours at $45 per hour equals $450 before materials and other charges.
Which Duration formula and finish changes the gallon price
Duration Interior and Exterior are separate products, so the correct formula depends on whether the surface is indoors or exposed to weather. Finish choices such as flat, matte, satin, and semi-gloss can affect availability and price. A washable sheen may be useful in a busy hallway or kitchen, while flat paint can disguise minor wall irregularities.
Choose the product for the surface rather than comparing gallons as if every formula were interchangeable. Color changes also matter: a major shift from a dark wall to a light shade may require a tinted primer or an extra coat. If the surface is bare, repaired, or stained, ask whether primer is included in the quote.
Coverage is another cost driver. For example, 1,000 square feet of wall area may take about 3 gallons for one coat at 350 square feet per gallon, but roughly 6 gallons for two coats, plus a margin for waste. Ceilings, trim, and doors should be measured separately because they may need different products.
Save money by matching gallons and prep to the job
Measure wall height and length, subtract large openings, and calculate the number of coats before buying. Compare the result with the product label, then add a modest allowance instead of rounding up by several gallons. Buying all the paint for a color at once also reduces the risk of slight batch differences between purchases.
Accurate measurement and a clear scope are usually more reliable savings than skipping needed preparation. Ask the painter to distinguish routine cleaning and light patching from larger repairs, and confirm whether primer, paint, and supplies are included. Avoid paying for a premium finish where a lower-sheen option meets the room’s cleaning needs.
Store promotions and contractor pricing can lower the per-gallon amount, but compare the final price after tax and delivery. A discount is less useful if it leads to excess paint or a product that is not suitable for the surface. Keep leftover paint labeled with the product, color, and room for later touch-ups.
Interior and exterior gallon needs for common projects
Project size drives the paint total more than the label price alone. The examples below use about $90 per gallon and assume two coats on prepared surfaces; actual wall area and coverage can change the quantity. They exclude labor unless noted.
| Project | Estimated gallons | Paint cost | Typical total |
|---|---|---|---|
| Small bedroom, about 350 sq. ft. of walls | 2-3 gallons | $180-$270 | $450-$850 with labor |
| Living room, about 600 sq. ft. of walls | 4-5 gallons | $360-$450 | $650-$1,200 with labor |
| Exterior siding, about 1,500 sq. ft. | 9-11 gallons | $810-$990 | $2,500-$5,500 with labor |
Assumptions: Two coats, roughly 300-400 square feet per gallon per coat, standard access, and no major repairs.
How painter hours add to the Duration budget
A typical bedroom repaint may require 6-12 labor hours for protection, light preparation, and two coats, while a larger living room may take 10-18 hours. Exterior work can require substantially more time because of ladders, scraping, caulking, and weather-sensitive scheduling. Many contractors quote by the room or square foot rather than listing hourly rates.
Compare estimates by included tasks, not just the labor total. Check whether the quote covers moving furniture, repairing nail holes, protecting floors, applying primer, and cleanup. A low bid that excludes preparation or a second coat may not be comparable to a more complete estimate.
Regional labor rates change the installed price
Labor costs in major metropolitan areas can run about 15%-35% above national midrange estimates, while some rural markets may come in 10%-20% lower. Local demand, travel distance, home access, and contractor availability also affect the quote. Paint itself can vary by store and promotion, but labor is often the larger source of regional price differences on a full project.
Request two or three written quotes for the same room size and scope. Ask each painter to specify the Duration product, finish, number of coats, and whether the customer or contractor buys the paint. This makes differences in materials, prep, and warranty easier to identify.
Duration versus SuperPaint for a repaint budget
Duration usually carries a higher per-gallon price than Sherwin-Williams SuperPaint, which commonly budgets around $65-$90 per gallon at retail, depending on formula and promotion. The difference may add roughly $20-$35 per gallon, or $80-$175 on a five-gallon purchase. Actual prices vary by store and date.
The better value depends on the surface and the project’s expected wear. For a low-traffic room with sound walls, a less expensive product may meet the need. For a frequently cleaned interior or an exposed exterior, compare the product specifications and labor scope before choosing; a higher paint price does not replace proper cleaning, repairs, or application.
