UV-stable patio coatings for Chicago backyards — quartz broadcast, full polyaspartic and epoxy systems, all topped with a polyaspartic that won't yellow in the sun. Slip-resistant, flexible through freeze-thaw, installed by a local crew.
Same-week on-site visits
A Chicago patio takes more abuse than almost any other concrete in your house — UV all summer, freeze-thaw all winter, salt and de-icer in spring, sprinklers and grills in between. Uncoated slabs spall, stain, fade and turn slippery in the rain.
A properly coated patio seals the slab, locks in slip resistance, and stays good-looking in direct sun for years. We install three patio systems — quartz broadcast (our best for patios), full polyaspartic, and pigmented epoxy — and every one of them is finished with a UV-stable polyaspartic topcoat so the floor doesn't yellow in the sun.
Honest ranges for Chicago patios — including diamond-ground prep, crack and joint repair, materials and labor. Quartz is our top-tier patio option.

Ranges assume concrete in normal condition. Heavy spalling, deep stamped texture, or previously sealed patios may need extra prep — we'll flag those costs in writing before any work begins.

Decorative vinyl flake adds slip resistance and hides minor concrete weathering — both critical outdoors. Hover or tap any swatch to preview the blend on a real installed floor. We bring physical samples in real patio lighting to every estimate.
Quartz broadcast is our top-tier patio build, with a full polyaspartic system as the popular middle choice and an epoxy + polyaspartic build as the budget-friendly option. Every system is finished with a UV-stable polyaspartic topcoat.

The cost-effective patio build. A pigmented epoxy basecoat with flake broadcast, sealed under a UV-stable polyaspartic topcoat that blocks UV so the epoxy underneath doesn't yellow:
All three patio systems we install share the same prep — diamond grinding, crack repair and a UV-stable polyaspartic topcoat. The difference is what's between those layers, and how long the floor lasts.

We recently had our laundry room floor done with epoxy, and I couldn't be happier with the results. Professional, punctual, and clearly experienced. They took the time to properly prepare the surface, which really shows in the final outcome. The finish is smooth, durable, and looks absolutely amazing.
Laundry Room · EpoxyThe basement and steps were done beautifully — clean, smooth, and very professional. The team worked efficiently and paid close attention to detail. Highly recommend.
Basement & Stairs · EpoxyThese guys are honest and do a great job. I would recommend them to anyone. They really know what they are doing.
Floor RefinishingWe coat outdoor patios across the entire Chicago metro — from the city to the far suburbs.
We also travel for select projects in southern Wisconsin and northwest Indiana — contact us to discuss your location.
The same sequence on every Chicago patio — assess, grind, repair cracks and joints, prime, basecoat with flake or quartz broadcast, and a UV-stable polyaspartic topcoat.
We walk the patio, inspect the slab for cracks, spalling, efflorescence and existing sealers, look at sun exposure and how you use the space, then recommend epoxy, full polyaspartic or quartz. You get a written estimate before scheduling.
We mechanically grind the entire patio with industrial diamond tooling to open the concrete pores and remove old sealer, paint or weak surface material. Outdoor slabs almost always have a weathered top layer that has to come off before any coating is worth applying.
Cracks, pits and spalls are filled with a flexible filler that moves with freeze-thaw. Expansion joints are honored and re-cut after the coating cures so the patio can keep moving without breaking the finish.
We prime the slab and apply the basecoat for the system you chose — pigmented epoxy, full polyaspartic, or epoxy primer for quartz. Each is matched to slab temperature and weather conditions on the day of install.
For flake systems we broadcast vinyl flake into the wet basecoat. For our top-tier quartz patio system we broadcast colored quartz aggregate to refusal — that's what creates the built-in slip resistance and a 15–25 year lifespan.
A clear, UV-stable polyaspartic topcoat is rolled over the cured basecoat. This is the layer that blocks UV, repels stains, locks in the texture and keeps the patio looking new for years. We walk the finished floor with you and leave care instructions.
Direct answers to the questions Chicago homeowners ask us most before coating their patios.
Not when it's installed correctly. We always finish outdoor patios with a UV-stable polyaspartic topcoat. Polyaspartic is aliphatic — its chemistry doesn't break down under sunlight the way pure epoxy does.
Coatings that yellow outside are almost always epoxy-only systems with no UV-stable topcoat on top. That's why we never leave an epoxy basecoat exposed on a patio.
No. Every outdoor patio we coat gets either a vinyl flake broadcast or a quartz aggregate broadcast — both create a textured surface that stays grippy when wet. Quartz broadcast in particular has built-in, ASTM-rated slip resistance and is our top recommendation for patios that see a lot of rain, snow or barefoot traffic.
Most Chicago-area patios run $6–$10 per square foot for an epoxy-with-polyaspartic-topcoat or full polyaspartic system, and $9–$14 per square foot for a quartz broadcast system.
A typical 400 sq ft patio falls in the $2,400–$4,000 range for a polyaspartic flake build; quartz patios start around $3,600 for the same footprint. Final price depends on slab condition, system, and any concrete repair needed.
Yes — that's specifically why we use polyaspartic topcoats outdoors. Polyaspartic stays flexible across a wide temperature range, so it expands and contracts with the slab instead of cracking off it. Quartz broadcast systems add another layer of toughness on top of that, which is why quartz is our most durable patio option.
Quartz broadcast combines three things outdoor coatings need most: built-in slip resistance from the aggregate itself, exceptional impact and abrasion resistance, and a 15–25 year realistic lifespan with proper maintenance. The polyaspartic topcoat over the quartz handles UV.
The downside is cost — quartz patios are typically 30–60% more than a polyaspartic flake build. If budget allows, it's the patio system we recommend.
Yes. We diamond-grind the slab first, which removes the existing sealer, knocks down the high spots, and gives us the mechanical profile we need for the new coating to bond. Heavily stamped or deeply textured patios may need additional repair work to level the surface — we'll flag that in writing in the estimate.
With proper prep and a UV-stable topcoat: epoxy + polyaspartic systems typically last 8–12 years; full polyaspartic systems last 10–15 years; quartz broadcast systems last 15–25 years.
The single biggest factor is surface preparation — coatings applied over an inadequately ground slab will fail regardless of the product. The second biggest factor is whether the topcoat is actually UV-stable.
We need dry concrete and a slab temperature of roughly 35°F+ for polyaspartic and quartz systems, and 50°F+ for epoxy. We monitor slab temperature with an infrared thermometer and watch the forecast — if rain is moving in before the coating cures, we reschedule. Most Chicago patio installs happen April through October.
Yes. Once fully cured (typically 24–72 hours depending on the system), the coating is chemically inert and safe around kids, pets, food prep, BBQ pits and patio furniture. We use low-VOC formulations and provide cure-time and care instructions at handover.
Polyaspartic-based topcoats are flexible and tolerate the hairline movement that's normal in Chicago patio slabs. We also pre-fill cracks and honor expansion joints during install. If the slab develops a major structural crack later, the coating will eventually telegraph that crack — but normal hairline movement won't break the finish.
