Concrete patio resurfacing costs $3 to $15 per square foot in Central Indiana. That’s about $900 to $4,500 for a typical 300-square-foot patio. A basic overlay runs $3 to $7, a spray-texture finish $4 to $8, and a decorative stamped or stained overlay $7 to $15. But the price only applies if the slab underneath is structurally sound. If the base has settled or cracked through, no overlay will fix it, and you’re looking at full replacement at $8 to $20 per square foot instead.
That structural question is the one most homeowners skip on the way to a quote, and it’s where money gets wasted. A $3 overlay poured over a failing slab cracks and peels within a few years. Mattingly Concrete checks what’s happening beneath the surface before recommending resurfacing or replacing concrete patios. See the cost of each resurfacing option, the signs your patio needs replacing instead, and what moves the final price in the sectioins that follow.
Basic Overlay Resurfacing Costs
A standard concrete overlay applies a thin layer of polymer-modified cement over the existing surface. This works when the slab is structurally sound but cosmetically worn. Basic overlays run $3 to $7 per square foot in Central Indiana, putting a 300-square-foot patio between $900 and $2,100.
Prep involves cleaning the existing slab, repairing small cracks with filler, and applying a bonding agent before the overlay goes down. The result is a fresh, uniform surface in broom or smooth troweled texture. Overlays add roughly a quarter inch of material, so they do not raise the surface enough to affect door clearances or adjacent landscaping.

Decorative Resurfacing Options
Stamped and Stained Overlays
Decorative overlays add color, pattern, or texture to the resurfaced patio. Stamped overlays replicating stone, slate, or brick cost $7 to $15 per square foot. Acid staining or integral color on a smooth overlay runs $5 to $10 per square foot. A 300-square-foot patio with a stamped overlay costs $2,100 to $4,500. These finishes need resealing annually before winter to maintain the color and pattern definition.
Spray-Texture and Knockdown Finishes
Spray-applied coatings create a textured, slip-resistant surface popular for pool decks and covered patios. These run $4 to $8 per square foot. Application is faster than stamping, which reduces labor costs on larger projects.
When Resurfacing Won’t Work
Resurfacing fails when the slab has problems a surface layer cannot fix. Signs that your patio needs replacement rather than resurfacing include:
- Cracks wider than a quarter inch or running through the full slab depth
- Sections settled more than half an inch below adjacent areas
- Widespread spalling where the surface flakes off in large pieces
- Base failure causing rocking or shifting when you step across the slab
Full replacement runs $8 to $20 or more per square foot, putting a 300-square-foot patio at $2,400 to $6,000. That is more expensive than resurfacing but addresses the root cause and provides a surface that should last 25 years with proper maintenance. Homeowners weighing materials can compare the tradeoffs between concrete and paver patios to decide which direction fits their goals.
What Affects Your Final Price?
Several factors push patio resurfacing costs beyond the base per-square-foot rate:
- Patio size: Larger patios benefit from economies of scale. Per-square-foot cost typically drops on projects over 400 square feet.
- Existing condition: Extensive crack repair or leveling before the overlay adds $1 to $3 per square foot in prep costs.
- Access: Patios behind fences or down slopes require more manual material transport, which increases labor time and cost (a common factor on the wooded, sloped lots around Zionsville and Geist)
- Finish complexity: Multi-color stamped patterns and custom borders cost more than single-color broom finishes due to additional labor and materials.
Frequently Asked Questions
How long does patio resurfacing last?
A quality overlay on a structurally sound slab lasts 8 to 15 years with annual sealing before winter. Thicker decorative overlays tend to outlast basic coatings because of better material adhesion.
Can you resurface a patio in cold weather?
Overlay products need sustained temperatures above 50 degrees Fahrenheit for proper curing. In Central Indiana, the resurfacing season runs from late April through mid-October.
Is resurfacing cheaper than replacing a patio?
Yes, when the slab is structurally sound. Resurfacing costs roughly one-third of full replacement. Resurfacing a compromised slab wastes money because the overlay will crack and debond within a few years.
Choose the Fix That Fits
Resurfacing is the cheaper, faster route (roughly a third of what it costs to replace it), but only when the slab below is solid. Pour an overlay over a patio that’s settling or cracked through, and you’ve spent money on a surface that will fail in a couple of years. The honest first step isn’t pricing the overlay; it’s finding out whether your slab can take one.
That’s the part worth getting right before you commit. Mattingly Concrete looks at every patio before recommending a direction, so you don’t end up paying for a fix that won’t hold. Call (317) 867-4049 or request a free consultation online to find out which option fits your patio.
