Sundek typically costs $5-$15 per square foot installed, with many standard residential projects averaging about $9 per square foot. The final quote depends on the existing concrete, surface design, preparation, project size, and local labor rates; repairs or premium finishes can push the price above that range.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed Sundek surface | $5 per sq ft | $9 per sq ft | $15 per sq ft | Typical residential overlay on serviceable concrete |
| 300-sq-ft patio | $1,500 | $2,700 | $4,500 | Basic to detailed finish, before major repairs |
| Concrete repair and prep | $1 per sq ft | $3 per sq ft | $8 per sq ft | Varies with cracks, coating removal, and slab condition |
| Custom color or pattern | $2 per sq ft | $4 per sq ft | $7 per sq ft | Additional design work beyond a simple finish |
What Sundek costs on a typical patio or pool deck
For a straightforward application over sound concrete, budget about $5-$10 per square foot for a basic texture or color, and about $8-$15 per square foot for a more decorative finish. A 500-square-foot patio therefore commonly falls between $2,500 and $7,500. Smaller jobs may carry a minimum charge, so their effective per-square-foot price can be higher.
A practical planning figure is $9 per square foot for an average residential installation. This assumes accessible, cured concrete; ordinary cleaning and surface preparation; standard color choices; and a local installer using a typical residential crew. A quote based on a complex stencil, multiple colors, extensive patching, or a difficult pool-deck layout will exceed that baseline.
Sundek is a branded concrete resurfacing system, and the installed price is usually quoted as a project rather than as a bag of material. The labor, surface preparation, coating layers, texture, sealer, and contractor overhead all contribute. Material-only prices do not represent the finished installed cost.
Large, open slabs can cost less per square foot than small patios because setup and mobilization are spread over more area. A 1,000-square-foot deck may receive a lower unit rate than a 150-square-foot landing, even if the larger job has a greater total. Assumptions: U.S. residential labor, standard access, sound concrete, and no major demolition or drainage work.
How surface preparation and finish layers shape the quote
Contractor estimates commonly combine cleaning and mechanical preparation, patching, overlay application, decorative work, sealer, and labor. The exact breakdown varies by installer and Sundek system, so homeowners should ask what is included instead of comparing only the headline price per square foot.
| Quote component | Typical price | What changes the charge |
|---|---|---|
| Cleaning and surface preparation | $0.50-$2.50 per sq ft | Oil, old coatings, and required grinding |
| Concrete patching and crack work | $1-$8 per sq ft | Repair area, crack movement, and patch depth |
| Overlay materials and application | $3-$8 per sq ft | System type, number of coats, and thickness |
| Texture, color, or pattern work | $2-$7 per sq ft | Custom colors, stencils, borders, and hand work |
| Sealer and final detailing | $0.75-$2.50 per sq ft | Sealer type, number of coats, and slip texture |
| Labor and contractor overhead | $2-$6 per sq ft | Crew size, travel, setup, and local rates |
These ranges are cost components, not amounts that should automatically be added together. Some contractors include preparation, application, and sealer in one installed rate. Others list repairs separately or include a limited amount of patching in their base price.
Confirm whether the quote includes grinding, crack repairs, sealer, and cleanup. Ask for the measured square footage and a written description of finish and exclusions. Labor-only calculations can be estimated with ; concrete coating crews may charge about $50-$100 per worker-hour when work is billed by time, though most residential projects are priced by area.
How slab condition, deck size, and pattern change the price
The slab is the largest uncertainty. A clean, stable surface needs less work than concrete with loose coating, oil contamination, spalling, or active cracks. Minor isolated patching may add a few hundred dollars; widespread deterioration can add $1,000-$4,000 or make resurfacing unsuitable until the underlying problem is corrected.
Cracks that move or reflect structural movement are not solved by simply covering them. An installer may need to evaluate the cause, route and fill cracks, or recommend replacement rather than an overlay. Ask whether the price includes a defined repair allowance and how extra repairs are authorized.
Size affects both total and unit pricing. Jobs below roughly 200 square feet may face a $500-$1,500 minimum for setup, travel, and crew time. Open areas above 600-800 square feet can sometimes receive a lower per-square-foot rate if the layout is simple and preparation is consistent.
Finish selection also matters. A single integral or applied color with a light texture is generally less expensive than multiple colors, borders, stencils, or a simulated tile pattern. Custom decorative work can add $2-$7 per square foot, while unusually intricate designs may require a separate fixed charge.
Pool decks often need a texture selected for wet-foot traffic and may include curved edges, drains, coping transitions, or furniture and equipment that must be moved. These details can raise labor time even when the total area is modest. A 600-square-foot open patio and a 600-square-foot pool deck should not be assumed to have identical quotes.
How to control the Sundek finish and scope
The most controllable cost decision is often the finish specification. Choosing one standard color and a straightforward texture can avoid custom design charges while still refreshing worn concrete. Before selecting a lower-cost finish, confirm that it meets the intended appearance and slip-resistance needs for the location.
Define the exact area and finish before requesting bids. Include steps, vertical faces, borders, and pool coping in the measurement, or list them separately. A contractor should identify which surfaces are included so a low initial rate does not become a series of unplanned add-ons.
Complete simple access preparation before the crew arrives when the installer permits it. Moving patio furniture, pots, and movable planters can reduce paid labor and prevent delays. Do not attempt chemical stripping, grinding, or repairs without the contractor’s direction; unsuitable preparation can damage the slab or interfere with adhesion.
Compare at least three written estimates that use the same square footage, repair assumptions, texture, color, and sealer. Ask each bidder to separate optional upgrades from required work. If the concrete is stable and the existing appearance is acceptable, a limited repair or resealing may cost less than resurfacing the entire area.
How installation hours and weather affect project cost
A typical residential application may take two to four working days on site, although the crew may not work continuously for that entire period. Cleaning, grinding, repairs, coating layers, decorative steps, and drying intervals all affect the schedule. A 300-500-square-foot uncomplicated slab may need a small crew for one to three active workdays, with additional time for curing.
Labor rates vary substantially by location. A commonly encountered installed labor allowance is about $2-$6 per square foot, while contractor time rates may run $50-$100 per worker-hour. High-cost metro markets, long travel distances, limited access, stairs, or a job that requires hand application can raise the labor portion.
Weather delays can affect both timing and the finished coating. Installers generally need suitable surface and air conditions, and rain, excessive humidity, or very hot conditions can postpone application or curing. Scheduling during a contractor’s less busy period may improve availability, but discounts depend on local demand and the project calendar.
Ask how long the surface must remain unused after application and whether furniture, vehicles, or pool traffic require different waiting periods. A quote that includes multiple mobilizations or return visits may cost more, but those trips can be necessary when repairs or coating layers need separate curing time.
How Sundek prices compare across U.S. regions
Rates can differ by about 10%-25% between lower-cost rural markets and high-cost metropolitan areas, reflecting wages, insurance, travel, and contractor availability. A basic finish priced near $7 per square foot in a lower-cost market might be quoted at $8-$9 in a large city before accounting for surface condition or design upgrades.
Climate influences demand and scheduling, but it does not set a single regional price. Warm-weather markets may have more pool-deck specialists and a longer outdoor installation season; busy periods can still increase wait times. In colder areas, the workable season may be shorter, and freeze-thaw damage can make concrete repairs more important.
Compare local bids rather than applying a national rate without adjustment. For a 400-square-foot standard patio, a rough range of $2,000-$6,000 covers many U.S. quotes, while an expensive metro area or a heavily detailed surface may exceed it. Travel charges can matter in rural areas where a qualified installer must come from farther away.
Regional comparisons are most useful when the scope is identical. Check whether both estimates include the same prep, repair allowance, coating system, color, pattern, and sealer. If one bid is much lower, ask whether it excludes crack work, perimeter detailing, or final protection rather than assuming the difference is a local discount.
When repairs, removal, or access add separate charges
Old paint, sealers, or failed coatings may need to be removed before a new overlay can bond. Depending on the coating and removal method, this work can add about $1-$5 per square foot. Thick or stubborn material, multiple old layers, or disposal requirements can push the cost higher.
Common add-ons include crack repair, spall patching, edge work, masking, drainage adjustments, and moving heavy objects. Contractors may charge $100-$500 for a small repair visit or include a limited quantity of patching in the full project. Ask for unit rates for additional repairs, such as per linear foot of crack or per square foot of patch.
Access and removal are often more important than the price of the overlay material. Narrow gates, steep stairs, long hose runs, limited parking, or an occupied pool area can slow work and increase setup time. Demolition and replacement of badly damaged concrete are separate scopes and can cost roughly $8-$18 per square foot or more, depending on removal and site conditions.
Delivery or disposal may appear as a separate line item when equipment, removed coating, or debris must be hauled away. A modest allowance might be $100-$500, while substantial demolition can cost more. Confirm whether cleanup, masking, and protection of adjacent walls or landscaping are included.
Is a Sundek overlay cheaper than replacing concrete?
Resurfacing generally costs less than removing and repouring concrete when the slab is structurally sound. A basic overlay at $5-$15 per square foot can refresh color and texture without the full expense of demolition, hauling, forming, and new concrete placement. The overlay does not correct sinking, major settlement, or a failing base.
Concrete replacement often runs about $8-$18 per square foot for a typical residential slab, with thicker sections, reinforcement, access difficulty, and disposal increasing the total. Decorative stamped concrete may cost more. Prices vary, and a small replacement job can have a higher unit rate because of minimum labor and mobilization charges.
Repair is the better price comparison only when it addresses the cause of the damage. A localized patch may cost around $150-$800 for a small area, but repeated patching of widespread spalling can become poor value. Ask an installer whether the existing slab can reliably support an overlay and whether moisture or drainage issues need attention first.
Maintenance also belongs in the comparison. A sealer may need renewal every few years depending on traffic, sun, water exposure, and product instructions. Budget roughly $0.75-$2.50 per square foot for professional resealing when needed; this is not necessarily an annual expense. An estimate should identify the coating and sealer so maintenance guidance matches the actual system.
What three common Sundek quotes can include
A 250-square-foot front entry with sound concrete, one color, and light texture might be quoted at $6-$9 per square foot, or about $1,500-$2,250. A small-job minimum, steps, or detailed edging could raise the total. This example assumes only routine preparation and no extensive crack repairs.
A 500-square-foot backyard patio with standard texture and several small patches might fall around $7-$12 per square foot, or $3,500-$6,000. The estimate may include grinding, overlay, one color, and sealer. Custom borders or a second color could add several hundred dollars to more than $1,000, depending on design and labor.
A 700-square-foot pool deck with a decorative pattern, multiple colors, and moderate crack work might cost about $10-$17 per square foot, or $7,000-$11,900. Curved edges, drain details, furniture moving, or coating removal can move it higher. The higher rate reflects more labor and surface detail, not simply more material.
Use these examples to check scope, not as guaranteed bids. For a useful estimate, provide photos, approximate dimensions, location, access details, and information about existing coatings or repairs. A site inspection is important when the slab has movement, extensive cracking, or uncertain drainage.
Questions that clarify a Sundek price quote
Before approving work, ask which specific Sundek system and finish are included, how many colors or decorative steps are priced, and whether the quoted square footage includes vertical surfaces or stairs. These details can explain why two bids for the same patio differ by thousands of dollars.
Ask what preparation is included and what conditions trigger extra charges. A strong estimate states whether grinding, coating removal, crack treatment, patching, masking, sealer, and cleanup are part of the base price. It should also show how unanticipated repairs will be priced and approved.
Get the warranty and maintenance terms in writing. Confirm what the workmanship warranty covers, how long it lasts, and whether it excludes movement, moisture, or pre-existing concrete failure. Warranty coverage varies by installer and system; a higher quote should not be assumed to include broader protection.
Finally, check payment milestones, estimated work dates, curing time, and the contractor’s insurance and references. Compare the complete delivered scope, not only the lowest per-square-foot number. The most useful bid identifies the finished appearance, repair limits, materials, schedule, and total price in clear terms.
