Industrial 100% solids epoxy with broadcast color flake, built for South Dakota winters and Black Hills salt.
A bare concrete garage slab in Rapid City takes a beating. Between the calcium chloride de-icer city crews dump on every street, the -20°F windchills that drive moisture deep into the slab, and the freeze-thaw cycle that runs from October through April, an untreated garage floor will pit, spall, and dust within four winters. Our 100% solids epoxy garage floor system is engineered specifically for that climate.
We start with diamond grinding to a CSP-3 concrete surface profile. That is the same prep used on industrial warehouses and aircraft hangars, and it is the only way to guarantee that the resin chemically bonds to the slab instead of just sitting on top. We never use acid etching, which is what most discount installers do because it is faster and cheaper. Acid etching gives you a 3-year floor at best.
Once the slab is profiled, we structurally fill every crack, pit, and spalled area with polyurea or urethane, then broadcast 100% solids pigmented epoxy at roughly 15 mils thick. Vinyl color flake is broadcast to refusal into the wet base coat (you pick from 50+ blends), excess flake is reclaimed, and the floor is finished with a clear polyaspartic or polyurethane topcoat that handles hot tires, hydraulic fluid, brake fluid, gasoline, motor oil, and de-icer without staining or softening.
The finished system is roughly 25 to 30 mils thick — about the same thickness as a credit card — and it is harder than the concrete underneath it. It comes with a 10-year adhesion warranty. We install across Rapid City, West Rapid, South Rapid, Black Hawk, Box Elder, Piedmont, Summerset, and Rapid Valley.
We measure, photograph slab condition, and deliver a flat written price within 24 hours.
Concrete is mechanically profiled to CSP-3 using counter-rotating diamond grinders with HEPA dust extraction.
Polyurea or urethane fills every defect. The floor becomes flat, continuous, and ready for resin.
100% solids pigmented epoxy is rolled at 15 mils, then vinyl color flake is broadcast to full refusal.
Clear polyaspartic or polyurethane topcoat seals the floor. Walkable in 24 hours, vehicle-ready in 48.
Properly installed 100% solids epoxy with diamond grinding and a polyaspartic topcoat will last 10 to 15 years in the Rapid City climate before needing a refresh coat. The system is warranted against adhesion failure for 10 years. Failures we see in this market are almost always traced back to acid etching prep or water-thinned big box product, not to climate.
Yes, with caveats. The slab and ambient air must be above 50°F for at least 24 hours during cure for standard epoxy. We bring in propane heaters and insulated curing blankets for winter installs. For homeowners who want a true cold-weather install, we recommend our polyaspartic system, which cures down to -30°F.
Not with our system. Hot tire pickup happens when cheap water-based or solvent-based epoxy is installed too thin or without proper concrete prep. Our 100% solids epoxy with a polyaspartic topcoat is fully cured chemically and has no plasticizer for hot rubber to leach. We have zero hot tire pickup callbacks on file.
Yes. About 1 in 4 Rapid City jobs we quote is a tear-out of a failed big box kit. We diamond grind down to bare concrete, profile to CSP-3, repair any damage left behind, then install our system. Removal adds roughly $0.50 to $1.00 per square foot.
10 years against delamination, peeling, and chemical staining when properly maintained. The warranty is transferable to a new homeowner one time, which boosts resale value. Hot tire pickup, salt damage, and chemical staining are all covered.
A standard 2-car garage in Rapid City (400 to 500 sq ft) with our full epoxy plus color flake plus polyaspartic topcoat system runs $1,800 to $3,500 installed. Slab condition, square footage, and flake choice are the three biggest variables. Free on-site quotes are available within 24 hours.
Most DIY garage epoxy fails within 18 months because the prep step is wrong. Diamond grinding to CSP-3, real crack repair, and moisture testing are what make a coating last 15 years.
