What an 80-pound bag costs for a countertop pour
Quikrete Countertop Mix is a specialized bagged concrete blend for cast-in-place or precast concrete countertops. An 80-pound bag commonly sells for $25-$40, and a practical budgeting figure is about $32. Local availability, retailer pricing, freight, and whether the product is stocked or special ordered can shift the amount.
One bag yields approximately 0.6 cubic feet, though actual yield can vary with handling and placement. At a 1.5-inch slab thickness, that volume covers roughly 4.8 square feet before allowing for waste. A 2-inch-thick countertop uses about 25% more mix per square foot than a 1.5-inch slab.
For the concrete alone, budget roughly $5-$10 per square foot at 1.5 inches thick. This estimate excludes the mold, reinforcement, labor, pigment, polishing, and sealer. Add a modest waste allowance, especially for small projects where leftover mix may not be reusable.
Assumptions: 80-pound bags, approximately 0.6 cubic feet of yield per bag, and a 1.5-inch countertop thickness.
How bag count changes with countertop dimensions
Estimate concrete volume by multiplying countertop length by width by thickness, with all measurements converted to feet. Divide cubic feet by about 0.6 to estimate bags, then round up. A 25%-30% thicker edge or built-up front apron increases volume beyond the flat-slab estimate.
| Countertop size | Approximate area | Mix at 1.5 inches | Bag cost range | Planning note |
|---|---|---|---|---|
| 6 ft by 2 ft | 12 sq ft | 3 bags | $75-$120 | Buy an extra bag if the pour has a deep edge |
| 10 ft by 2 ft | 20 sq ft | 5 bags | $125-$200 | Does not include a sink cutout or waste reserve |
| 30 sq ft kitchen run | 30 sq ft | 7 bags | $175-$280 | Eight bags provide a more cautious allowance |
These are volume-based estimates, not a substitute for measuring the actual mold. Sink and cooktop openings reduce the flat area, but thickened edges, integrated backsplashes, waterfall details, and irregular shapes can use additional concrete. A bag’s printed yield and the final form dimensions should control the purchase quantity.
Small counters can cost more per square foot because a full extra bag and setup supplies are still needed. For larger counters, waste and delivery become more important, while the concrete price per square foot remains relatively predictable at a consistent thickness.
What goes into a Quikrete countertop project quote
The bag price is only one part of the cost. A DIY pour also requires a rigid mold, reinforcement, mixing and finishing tools, and a compatible sealer. Material choices and whether the countertop is poured in place or cast in a separate mold change the balance of expenses.
| Cost component | Typical range | Pricing basis | What changes the bill |
|---|---|---|---|
| Countertop mix | $5-$10 per sq ft | About $25-$40 per 80-lb bag | Slab thickness, waste, store availability |
| Forms and mold supplies | $3-$12 per sq ft | DIY materials, often more for reusable molds | Melamine, custom curves, edge profile |
| Reinforcement | $1-$6 per sq ft | Mesh, rebar, or fiber additions as specified | Overhangs, cutouts, slab dimensions |
| Labor | $35-$85 per hour | One or more workers, depending on job | Mixing, placement, finishing, access |
| Finish and sealer | $2-$10 per sq ft | Grinding, polishing, color, protective coating | Finish quality and number of coats |
| Delivery and disposal | $0-$150 | Per order or project | Distance, minimum fees, debris volume |
For a modest DIY countertop, combined materials commonly land around $12-$45 per square foot. The low end assumes simple dimensions, basic forms, and minimal finishing; the high end allows for upgraded edges, reinforcement, pigments, polishing supplies, and a suitable sealer. Tool purchases can add roughly $50-$300 if the homeowner does not already own a mixer, grinder, or finishing equipment.
Contractor quotes include more than pouring the mix. They may cover design, templating, mold fabrication, transportation, installation, cutouts, finishing, and warranty provisions. Ask whether the quote includes removal of an existing counter, sink installation, and sealing. Those items are often separate charges.
Why thickness, cutouts, and color shift the mix budget
Thickness is a direct driver of bag count. At 1.5 inches, the estimated coverage is about 4.8 square feet per bag; at 2 inches, it falls to about 3.6 square feet. A 3-inch thick edge detail can use substantially more material locally, even when the main slab remains thinner.
Cutouts create more layout and reinforcement work than their reduced concrete volume suggests. A sink opening can require extra bracing, careful placement, and edge finishing. A large unsupported overhang—particularly one extending more than 10-12 inches—may need engineered support or a stronger reinforcement design, increasing labor and materials.
Color and surface finish also affect the budget. Integral pigment can add approximately $2-$8 per square foot, depending on pigment amount and product, while specialty aggregates or exposed-aggregate finishes can add more. Grinding and polishing may add $5-$20 per square foot when performed by a professional or with rented equipment.
Access and pour timing matter because countertop concrete should be mixed, placed, and finished consistently. Narrow stairs, long carries, limited work space, or multiple disconnected sections may require more crew time. A project with several small pours can be harder to color-match and finish than one continuous pour.
Measure the thickest edge and every built-up detail before converting square footage into bags. For labor budgeting, a crew rate can be estimated as ; the actual hours depend on molds, access, number of sections, and finish specification.
How labor and installation change the total
DIY labor is unpaid, but mixing and handling 80-pound bags takes time and physical effort. A small, straightforward pour may need two people for mixing, placement, and finishing, with several hours of active work plus form preparation and curing time. A larger kitchen project may require a crew of three or more to keep multiple batches moving consistently.
Professional labor rates often fall around $35-$85 per hour per worker, but countertop contractors typically quote by project or square foot rather than hourly. Fabrication and installation together commonly produce installed totals of about $70-$160 per square foot. Custom colors, integrated sinks, unusual profiles, and remote locations can push a quote above that range.
Installation style influences labor. Cast-in-place work avoids moving a heavy finished slab but requires protecting cabinets and managing the pour in the kitchen. Precast work allows controlled shop finishing, but lifting, transport, seams, and site access become concerns. A narrow stairwell or a long carry from the truck can add labor or equipment charges.
Compare installed quotes only when they cover the same dimensions, cutouts, edge details, finish, and sealer. One contractor may include templating and installation while another quotes fabrication alone, making the lower headline price misleading.
Three sample budgets for different countertop scopes
These examples use estimated U.S. retail and labor pricing rather than fixed local quotes. They illustrate how the same mix can fit very different project budgets once forms, finishing, and installation are counted.
| Project scenario | Mix and labor details | Estimated total | Approximate price per sq ft |
|---|---|---|---|
| DIY vanity top, 8 sq ft | 2 bags at $32 average, basic mold, mesh, sealer, and supplies | $180-$360 | $23-$45 |
| DIY kitchen run, 20 sq ft | 5-6 bags, reinforced sections, custom forms, color, and rented tools | $500-$1,100 | $25-$55 |
| Installed kitchen counter, 30 sq ft | About 7-8 bags in the concrete estimate, professional fabrication and installation | $2,100-$4,800 | $70-$160 |
The DIY totals assume the homeowner performs the work and do not include major tool purchases or cabinet repairs. The installed example includes a typical custom-counter scope but may exclude demolition, plumbing reconnection, unusual support work, and sales tax. A detailed written quote is needed to confirm inclusions.
Regional prices and store availability across the U.S.
Bag prices can vary by retailer, freight, and local inventory. In regions where the mix is stocked locally, an 80-pound bag may be close to the lower end of the $25-$40 range. Special-order purchases or delivery to rural areas may cost more, particularly when a minimum delivery charge applies.
Professional installation prices often vary more than the mix itself. Urban markets with higher wages and operating costs can run about 10%-25% above a national midrange quote. Rural areas may have lower hourly rates, but travel charges and fewer countertop specialists can add 5%-20% to a small project’s effective price.
Climate and season can affect scheduling. Contractors in regions with cold winters may limit outdoor or garage casting during freezing conditions unless the workspace can be controlled. Busy construction periods can also reduce appointment availability or raise labor bids, while flexible scheduling may make it easier to compare quotes.
Price the delivered material total, not only the shelf price. For a small order, a $50-$100 delivery fee can outweigh a few dollars of difference between bags. Call local suppliers with the bag count and delivery address before choosing a retailer.
DIY forms versus hiring a concrete countertop installer
A DIY pour can make financial sense when the design is simple, the homeowner can build a stable mold, and the finish does not require specialized polishing. Basic material spending may be about $12-$45 per square foot, but mistakes can mean buying another mix batch or replacing a flawed section. The heavy bags and rapid work pace also make preparation essential.
A contractor may charge roughly $70-$160 per square foot installed, but the quote can include template work, mold construction, reinforcement, placement, polishing, transport, and sealing. The higher price pays for skilled execution and reduces the homeowner’s handling burden. It does not automatically include plumbing, cabinet modifications, demolition, or backsplash work.
Repairing an existing countertop is not usually comparable to replacing it with cast concrete. Small chips or surface damage may be repairable for $150-$500, depending on material and access, while a full concrete replacement involves fabrication and installation. A repair quote is worth comparing when the existing surface is structurally sound and the damage is limited.
DIY savings are greatest when the mold, tools, and work area are already available. For complex sink openings, long spans, repeated edge profiles, or polished finishes, compare the expected material savings with the cost of tools, rework risk, and professional labor.
Ways to lower the Quikrete countertop bill without cutting corners
Keep the design close to standard slab dimensions and avoid unnecessary thickened edges, complex curves, and multiple small sections. Confirm the finished thickness before buying supplies; reducing a slab from 2 inches to 1.5 inches can cut concrete volume by about 25%, provided the design and support requirements allow it.
Choose a practical finish and color early. A straightforward natural-gray surface can avoid pigment costs and simplify matching between batches. If color is important, calculate pigment consistently for every batch and follow product directions rather than estimating by eye. A compatible sealer should remain in the budget because an unfinished surface can stain or absorb liquids.
Compare at least three quotes with identical specifications. Ask each contractor to separate fabrication, installation, cutouts, polishing, sealer, delivery, and demolition. For DIY purchases, compare the full delivered cost and avoid buying far more mix than the design requires; however, do not plan a pour so tightly that a small volume error forces a delayed second batch.
Prepare the site before the crew arrives by clearing access, confirming cabinet level and support, and coordinating sink or cooktop measurements. Consolidating work into one visit can reduce travel and minimum labor charges. Do not remove reinforcement, required support, or the specified sealer solely to reduce the estimate.
