Promar 400 Flat typically costs about $40-$75 per gallon or $190-$325 for a five-gallon pail before tax, with actual quotes depending on store pricing, account discounts, and location. Painting adds a separate labor charge; wall condition, coverage, number of coats, and whether primer is needed determine the finished project budget.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Promar 400 Flat, 1 gallon | $40 | $58 | $75 | Paint only; tinting may affect price |
| Promar 400 Flat, 5 gallons | $190 | $260 | $325 | Typically lower per gallon than single cans |
| Paint for 1,000 sq ft of wall area | $80 | $145 | $260 | Two coats; assumes 350-400 sq ft per gallon per coat |
| Professional wall painting | $1,200 | $2,500 | $4,500 | Approximate labor and basic supplies; room and prep scope vary |
Assumptions: U.S. retail or contractor-store pricing, standard white or light tint, sound interior walls, and no major repairs.
What Promar 400 Flat Usually Costs by Can Size
Budget about $40-$75 for one gallon and $190-$325 for a five-gallon pail. These are practical shopping ranges rather than fixed national shelf prices. Store promotions, professional accounts, local distribution, and tint selection can move a quote outside the midpoint.
A single gallon averages roughly $58, or about $58 per gallon. A five-gallon pail averages around $260, equivalent to $52 per gallon. The larger container can save approximately $20-$115 compared with buying five individual gallons, but only when the project uses nearly all of it and the store’s pail price is favorable.
Paint coverage is commonly estimated at roughly 350-400 square feet per gallon per coat on a smooth, previously painted surface. For 1,000 square feet of wall area receiving two coats, the theoretical requirement is 5-6 gallons; buying 6-7 gallons allows for texture, touch-ups, and application waste. Assumptions: average coverage, smooth drywall, and a similar color underneath.
Deep colors, porous new drywall, rough texture, or a substantial color change can reduce coverage or require an additional coat. Product price also may differ for a tinted mix versus standard white. Ask the store to price the exact base and color rather than comparing a white-paint shelf tag with a tinted-paint quote.
How Paint, Labor, and Prep Shape the Quote
Paint is only one part of a room-painting estimate; surface preparation and labor can cost several times as much as the cans. The table gives typical planning ranges for a 1,000-square-foot wall area, not floor area. Labor rates and job minimums vary substantially by market and project size.
| Quote component | Typical range | Pricing basis | What changes it | Usually included |
|---|---|---|---|---|
| Promar 400 Flat | $200-$325 | $40-$65 per gallon in a multi-gallon purchase | Can size, store, tint, account discount | Paint only |
| Labor | $700-$2,500 | $35-$75 per hour or $1-$3 per sq ft of wall | Prep, room layout, crew speed, region | Application and routine setup |
| Primer and patch materials | $40-$250 | $20-$60 per gallon of primer, plus repair supplies | New drywall, stains, repairs, color change | Only if specified |
| Equipment and protection | $50-$250 | Per project | Masking, ladders, sprayer use, floor protection | Varies by contractor |
| Disposal and cleanup | $0-$100 | Per job | Leftover paint, debris, local disposal rules | Often basic cleanup only |
Contractor quotes may bundle several entries rather than list each as a separate charge. Confirm whether the estimate includes two coats, minor nail-hole filling, masking, moving furniture, primer, and cleanup. A quote that excludes prep may look cheaper but leave the homeowner responsible for buying materials or doing additional work.
For a rough labor calculation, a painter spending 20-32 hours at $45-$70 per hour produces $900-$2,240 in labor, before materials and any business overhead. Small projects may have a minimum charge, so a one-room job can cost more per square foot than a whole-home repaint.
Coverage, Coats, and Wall Condition Change Gallon Needs
Measure paintable wall area and plan for two coats before choosing between gallons and a pail. Room floor area is not the same as wall area: ceiling height, doors, windows, closets, and partitions affect the calculation. A simple estimate is wall length around the room multiplied by wall height, minus large openings.
At 350-400 square feet per gallon per coat, 500 square feet of wall area takes about 3 gallons for two coats, while 1,500 square feet takes about 8-9 gallons. Round up when walls are textured, absorbent, or changing from a dark color to a light one. A small reserve can be useful for future touch-ups, especially if the color is custom-tinted.
One coat may be adequate for a similar color on a smooth, well-painted wall, but it is not a safe budget assumption for every job. New drywall generally needs a suitable primer before finish paint. Stains, water marks, smoke residue, or strong color differences may call for a stain-blocking or specialized primer rather than another coat of flat finish paint.
Flat paint can help reduce the visibility of minor surface irregularities, but it does not repair them. Larger patches, peeling paint, grease, or water damage add labor and materials. Resolve moisture problems before repainting; otherwise, the finish may fail and require another expense.
One Gallon or Five Gallons for a Flat-Wall Project
Compare total usable paint needs, not just the lower price per gallon. A five-gallon pail usually makes sense when the measured job needs four or more gallons, the color is consistent throughout, and leftover storage is acceptable. One-gallon cans are often practical for a bedroom, isolated repairs, or several rooms using different colors.
| Purchase choice | Typical price | Approximate coverage for two coats | Cost consideration |
|---|---|---|---|
| 1 gallon | $40-$75 | 175-200 sq ft | Best for limited work; higher unit price |
| 2 gallons | $80-$150 | 350-400 sq ft | Useful for a small room or touch-up reserve |
| 5-gallon pail | $190-$325 | 875-1,000 sq ft | Lower unit price when most paint is used |
| Two 5-gallon pails | $380-$650 | 1,750-2,000 sq ft | May suit multiple rooms with one color |
Coverage figures are estimates, not a product guarantee for every surface. The actual amount may be lower on textured plaster or high-absorption surfaces. If a project needs just over five gallons, compare the price of a pail plus one gallon against two pails; the cheapest combination depends on current store pricing and whether a second color is involved.
Ask whether the paint can be tinted to the same formula across separate purchases. For a large job, buying enough at once can reduce the risk of slight batch or color variation. Keep the label and color formula for later touch-ups, and store sealed paint according to the manufacturer’s directions.
What Makes Promar 400 Quotes Higher in Some Cities
Local labor and store pricing usually create larger differences than the paint’s advertised coverage. As a budgeting guide, paint prices in lower-cost rural and smaller-market areas may run near the low end, while high-cost metropolitan areas can be 10%-25% above a national middle estimate. Contractor labor may differ by 20%-40% or more between markets.
Delivery charges, store availability, and whether a contractor buys through a commercial account also matter. A professional account can produce a better material quote than an individual retail purchase, but it does not guarantee that the customer receives the full discount. Compare the specified product, sheen, color base, and quantity on each quote.
Labor tends to be especially expensive in dense urban areas where parking, access, building rules, and elevator reservations slow the crew. Rural jobs can have travel or minimum-service charges. For a small interior repaint, those fixed costs can outweigh the difference between two paint stores.
Because local prices are not uniform, use the table ranges as a starting budget and request two or three written quotes for the same work scope. A useful comparison states the wall area, number of coats, surface repairs, primer, paint quantity, and whether ceilings or trim are excluded.
How Long a Painter Needs for Flat Interior Walls
Most of the labor charge comes from room preparation, cutting in, and applying coats—not simply rolling paint onto open walls. A painter may need 6-10 labor hours for a simple bedroom and 20-32 labor hours for approximately 1,000 square feet of wall area, depending on repairs and room layout.
A two-person crew might finish a straightforward 1,000-square-foot wall project in one to two working days, including ordinary setup and drying intervals. Extensive patching, furniture, high ceilings, detailed cut-ins, or occupied rooms can stretch the schedule. Drying time between coats is not always continuous labor, but it can prevent a same-day completion.
Hourly rates commonly fall around $35-$75 per painter, while some contractors price by room, square foot, or whole project. Rates reflect more than take-home wages; they may cover insurance, travel, setup, supervision, and business costs. Ask whether the quote is a fixed project price or an hourly estimate and how change orders are handled.
Access can change labor needs even when wall area stays constant. Stairwells, tall ceilings above 10 feet, tight rooms with heavy furniture, and extensive masking generally take longer than empty rooms with standard 8-9-foot ceilings. Prepare the space only if the contractor agrees that moving furniture or removing wall items is outside the quoted scope.
Primer, Repairs, and Removal That Add to the Paint Bill
Primer and repairs are conditional expenses, not automatic requirements for every repaint. Sound, previously painted walls in a similar color may need only cleaning and finish paint. New drywall often needs primer, while stains or repairs may need spot priming even if the rest of the wall is ready for two finish coats.
Basic patching supplies may add $10-$50 for a small DIY repair, while contractor patching can add roughly $100-$500 or more when damage is widespread. Stain-blocking primer generally costs more per gallon than basic wall primer. Confirm whether the contractor’s estimate includes spot priming, full-wall priming, or neither.
Removing wallpaper, scraping loose paint, repairing damaged drywall, or treating mildew can add substantial labor. Wallpaper removal may cost around $1-$3 per square foot, and drywall repair may be priced by the damaged area or as a minimum service charge. These tasks should be itemized because their cost depends on adhesion, number of layers, and the condition beneath the material.
Paint disposal rules differ by locality. Small amounts of leftover latex paint may be accepted through household hazardous-waste or paint-recycling programs, while some areas require special handling. Ask whether disposal is included before paying a separate haul-away fee.
Ways to Lower the Promar 400 Flat Project Price
The most reliable savings come from controlling the work scope and buying only the paint quantity the surface requires. Measure walls, identify the finish and color, and ask each bidder to quote the same number of coats and the same preparation tasks. That makes price comparisons more meaningful than comparing totals with different assumptions.
Choose a single color across several rooms when appropriate, then compare the cost of one pail with individual gallons. Avoid buying a pail solely for a lower per-gallon price if the project uses only two or three gallons. Before purchasing, verify the exact product name and flat sheen on the written estimate; a similarly named paint or a different finish is not a direct price comparison.
Do straightforward preparation before the crew arrives only when the contractor approves it. Removing small wall items, clearing access, and moving light furniture may reduce billed time. Do not sand unknown old paint or disturb suspect lead-based coatings; older homes may require appropriate testing and safe work practices.
Schedule flexible work during a contractor’s less busy period if the contractor offers a lower rate, but do not assume every season brings a discount. Avoid unnecessary full-wall priming when the walls do not need it, while keeping primer in the plan for new drywall, stains, or major color changes. Ask for separate prices for repairs and optional add-ons so essential work is not confused with upgrades.
Finally, check whether the quote includes paint at the contractor’s account rate or expects the homeowner to buy it. A lower labor quote can be offset by retail paint purchases, delivery, or added supply charges. Compare the complete material-and-labor total, and request a written explanation for unusually low or high quantities.
