The Challenge: A Large Crack in the Patio
Molly loved her outdoor space but had a problem she couldn't ignore: a large crack running through her patio concrete. She wanted it gone — not patched over so the repair still showed, but resurfaced so cleanly that the crack would disappear entirely. What she also needed was a contractor who communicated and delivered, and Duration Concrete Coatings turned out to be exactly that.
Why do outdoor patios crack in the first place?
An outdoor slab takes the weather head-on, which makes it one of the most freeze-thaw–exposed surfaces on a property. When water works into the concrete, freezes, and expands, the repeated internal pressure produces cracking over time. In the research literature, freeze-thaw damage is described as cracking and spalling driven by the progressive expansion of the cement paste under repeated freezing and thawing. Left alone, a large crack like Molly’s only widens season after season — which is why repairing it properly, then sealing the surface, matters.
The Duration Difference: Repair First, Then Resurface
The reason a bare or painted patio keeps failing is that paint is a cosmetic layer — it doesn't repair the slab or bond into it. Duration's approach is a full Duralast® polyaspartic system engineered for Indiana's climate, and on Molly's project the crack repair happened before any color went down. That sequence is the whole reason the finished patio reads as flawless: repair the concrete first, and the crack doesn't telegraph back through the coating.
Two properties of the system made it the right call for an outdoor patio. First, flexibility: the polyurea/polyaspartic build stays flexible and moves with the slab as it expands and contracts through the seasons, where a rigid coating is more likely to crack along with the concrete. Second, UV stability — which is essential for a surface in full sun, and is where polyaspartic decisively beats ordinary epoxy.
Will a patio coating yellow or fade in the sun?
Not with a UV-stable polyaspartic top coat — and this is measurable, not a slogan. Coating color change is scored in “delta E” (ΔE) under an accelerated weathering test; a ΔE above 2.0 is the point a shift becomes noticeable to the human eye. In published QUV chamber testing, a gray polyaspartic shifted just 0.89 ΔE after 500 hours, while a gray epoxy shifted 8.83 ΔE and visibly ambered over the same exposure. On a patio in full sun, that’s the difference between a surface that still looks new years later and one that has gone yellow.
From First Visit to Finished Patio
Duration completed Molly's patio in a single day. Here is how the project moved from assessment to a restored, revived outdoor space.
Step 1: On-Site Assessment (Duration: Same Visit)
Owner Dan handled the consultation personally, and Molly singled out his communication — professional, helpful, and prompt from the first contact. He assessed the crack and the slab, walked through the process and color options, and left her with a clear plan.
Step 2: Crack & Surface Repair (Duration: Day of Install)
Before any coating, the large crack was filled and re-profiled and the surface was repaired — restoring the slab to a sound, like-new base. This is the step that made the finished result flawless: with the crack properly repaired first, it would no longer show through the coating.
Step 3: Diamond Grind & Polyurea Base (Duration: Day of Install)
The patio was diamond-ground to a clean, open profile so the coating could bond into the concrete rather than sit on top, then a high-strength polyurea base coat was applied as the foundation of the system.
Step 4: Flake Broadcast & Polyaspartic Top Coat (Duration: Day of Install)
Duration’s crew — Luis and Richard — hand-broadcast the decorative vinyl flake in Molly’s chosen color for a consistent, textured finish, then sealed it under a clear, UV-stable polyaspartic top coat that carries the abrasion, weather, and sun resistance. Molly described their work as flawless and the crew as kind and professional throughout.

By the end of the day, the large crack that had bothered Molly was gone — repaired so cleanly that, in her words, “you would never know it was there.” The finished patio is seamless, easy to maintain, and built to hold up to Fort Wayne’s seasons rather than crack along with the slab beneath.
- The crack was repaired, not hidden. Filling and re-profiling before coating is why the finished surface reads as flawless.
- A patio built for the sun. The UV-stable polyaspartic top coat resists the ambering that turns ordinary outdoor coatings yellow.
- A space she’s proud to show off. Molly reports the patio has drawn many compliments — and she has already recommended Duration to others.
Is repairing and coating a cracked patio worth it?
For an outdoor surface that already shows cracking, the value case is strong — you’re solving a visible, worsening problem and upgrading your living space at the same time. Industry sources commonly cite a return in the range of roughly 65–85% for concrete floor coatings at resale, and a finished, crack-free patio adds real curb appeal and usable outdoor square footage.

Frequently Asked Questions
Can a large crack in a patio really be made invisible?
Yes. A quality installer repairs and re-profiles the crack first, restoring the slab to a like-new base before the coating goes on. On Molly’s patio the crack was repaired before resurfacing, so the finished surface showed no sign of it. Coating over an unrepaired crack is what fails.
Is polyaspartic a good choice for an outdoor patio?
It’s one of the best choices. A UV-stable polyaspartic top coat resists the yellowing and fading that ruin ordinary outdoor coatings, and the flexible build moves with the slab through freeze-thaw cycles instead of cracking along with it — which is exactly what an exposed patio needs.
How long does a patio resurfacing take?
Often a single day. Duration completed Molly’s patio in one day. Because the Duralast polyaspartic system cures quickly, the surface is typically ready for foot traffic within hours and normal use soon after — far faster than a multi-day epoxy system.
Will the finish hold up to Fort Wayne winters?
Yes. A bonded, non-porous coating creates a barrier that keeps moisture off the slab, which helps resist the freeze-thaw damage that cracks bare concrete. The flexible polyaspartic system is built to move with seasonal expansion and contraction rather than crack.
How much does patio crack repair and resurfacing cost?
