Is polyaspartic better than acrylic sealer for a concrete patio?
Yes, by 10-15× the lifespan. Acrylic sealers wear off in 12-24 months and offer minimal protection. Polyaspartic lasts 15+ years, doesn't yellow, doesn't peel, doesn't need re-application. The math: 5 acrylic re-seals over 15 years (DIY ~$200 each + labor) vs. one polyaspartic install ($2,000-2,500 for a typical 250 sq ft patio) that's done. The professional install is competitive on lifecycle cost and dramatically better-looking the entire time.
How much does a concrete patio coating cost in Wisconsin?
Polyaspartic patio coatings in River Falls, WI run $8-10 per square foot fully installed. A typical 250 sq ft patio is $2,000-2,500 all-in. Larger patios (400+ sq ft) come in at $3,200-4,400. Bundling stoops or walkways with a patio job runs ~$400-800 less than standalone because the equipment is already on-site.
Will the patio coating crack through Wisconsin winters?
Polyaspartic is engineered for slab movement and freeze-thaw. The basecoat is roughly 100% more flexible than epoxy and moves with the concrete through temperature swings. We've installed exterior coatings across western Wisconsin and the east Twin Cities since 2003 — the cracking failure mode genuinely doesn't happen on a properly prepped polyaspartic install.
Will it yellow in the sun?
No. Polyaspartic is UV-stable to the molecular level — the chemistry doesn't yellow, ever. We back this with a separate lifetime warranty against UV fading. Epoxy yellows within a summer; polyaspartic does not.
Is the patio surface slip-resistant when wet?
Yes. Every exterior install includes anti-slip aggregate broadcast into the topcoat. Texture level is calibrated to the use case — aggressive for stairs and stoops (where wet feet must not slip), smoother for covered patios where bare-foot comfort matters. We discuss the texture preference at the on-site quote.
When is the best time to coat a patio in Wisconsin?
Spring (April-June) and fall (September-October). The slab needs to be dry and the air temperature between roughly 50°F and 85°F for proper cure. Summer humidity slows it; winter is too cold. Exterior season is short in Wisconsin so book 4-6 weeks ahead during peak months.
Can you coat over an old, peeling concrete sealer?
Yes — diamond grinding removes most old sealers, paints, and previous coatings cleanly. Anything that doesn't come off with grinding gets addressed before the new system goes down. By the time the polyaspartic basecoat is rolled on, the slab is clean substrate.
What about spalled or chipped concrete — can you still coat it?
In most cases, yes. Spalled areas get rebuilt with polymer-modified concrete repair compound during prep, then the coating goes over a smooth surface. The exception: slabs that are structurally compromised (significant frost heave, deep spalling, foundation issues) should be replaced, not coated. Dave will tell you straight if your slab needs replacement instead of restoration.
What's covered under the warranty for an exterior coating?
15-year written warranty against chip, crack, and peel under normal exterior use. Lifetime warranty against UV fading. Exclusions: damage from abuse (vehicle parking, dropped weights, etc.), neglect, or improper chemical exposure. The warranty document is real — handed to you at install completion.
Can you coat a wraparound porch or wood-and-concrete combo?
We coat the concrete portions only. If your porch is mixed wood deck + concrete, we coat the concrete and you handle the wood with a deck stain or coating separately. We can quote both portions at the on-site visit and recommend a wood finish that complements the concrete coating color.
