Your Garage Floor Works Hard. Give It a Surface That Keeps Up.
Bare concrete is porous. It absorbs oil drips, road salt, and moisture. Over time it dusts, stains, and starts to look worse no matter how often you clean it. An epoxy coating bonds to the surface and seals it off completely, leaving you with a floor that's easy to sweep, resistant to chemicals, and tough enough to handle foot traffic, heavy equipment, and anything else your garage sees.
At Elite Sioux Falls Concrete Contractor, we do this work the right way: proper surface preparation first, then a multi-layer coating system that bonds and holds. We don't just roll on a product and walk away. We take the time to prep the concrete so the coating doesn't peel, bubble, or fail within a year.
Whether your garage floor is brand new or has years of grime and wear on it, we can assess it, prep it properly, and apply a coating that lasts. We serve homeowners and commercial clients throughout Sioux Falls and the surrounding communities.
Why Surface Preparation Is the Most Important Step
You've probably seen epoxy kits at the hardware store. The reason those jobs often peel and fail is not the coating — it's the prep work. Paint rollers and acid wash are not enough for most concrete floors. Here's what we do before a single drop of coating goes down.
- Shot blasting or diamond grinding: We mechanically profile the concrete surface to open up the pores and remove any weak surface layer. This creates the right texture for the coating to bond to. Without this step, coatings fail at the adhesion layer.
- Crack and joint repair: Any cracks, spalls, or control joint edges that could telegraph through the coating are filled and leveled with a patching compound before coating begins.
- Moisture testing: Moisture vapor coming up through the slab is one of the main causes of coating failure. We test the slab before we start and choose the right primer system for your moisture conditions.
- Primer coat: A penetrating epoxy primer soaks into the prepared concrete and creates a chemical bond between the slab and the top coat layers. This is what makes the coating stick for years rather than months.
- Broadcast layer or topcoat: Decorative flakes or quartz are broadcast into the wet base coat for texture and appearance, then sealed with a clear polyaspartic or polyurea topcoat for UV stability and chemical resistance.
If your garage floor slab itself needs to be repoured or resurfaced before coating, we handle that as well. See our concrete slab and foundation work service for more detail on slab installation and replacement.
Coating Options: What's the Difference?
Not all garage floor coatings are the same. Here's a plain-English breakdown of the systems we use and who each one is best for.
Standard Epoxy with Decorative Flake
This is the most common and most popular garage floor system. A solid-color epoxy base is applied and then flakes — small colored chips — are broadcast into the wet surface for texture and visual interest. The whole floor is then sealed with a clear topcoat. The result looks sharp, hides minor imperfections, and holds up extremely well to normal garage use. It comes in dozens of color combinations.
Polyaspartic Topcoat
Polyaspartic is a newer generation coating that goes on top of the base coat system. It cures faster than standard epoxy, is harder, and holds up better to UV exposure. This matters if your garage has windows or if the door is open often, since standard epoxy can yellow over time in UV-exposed areas. We use polyaspartic as the topcoat on most of our installations.
Quartz Broadcast System
Instead of decorative flakes, fine quartz aggregate is broadcast into the epoxy. This gives a more subtle, uniform texture with excellent slip resistance. It's a popular choice for shop spaces, utility garages, and commercial applications where function comes first.
Solid Color Epoxy
If you want a clean, minimal look without texture or flakes, a solid two-part epoxy system can give you exactly that. Available in a range of grays, tans, and other neutrals, it's a good fit for modern or minimalist garage spaces.

A professionally installed, multi-layer epoxy and polyaspartic system typically lasts 10 to 20 years with normal garage use. The biggest factors that affect longevity are the quality of the surface prep, the thickness of the coating system, and how well the floor is maintained. Routine sweeping and the occasional mop with a neutral cleaner are all it takes to keep it in top shape. Avoid dragging sharp metal objects and clean up chemical spills promptly to get the most out of your coating.
With a polyaspartic topcoat system, you can typically walk on the floor within 24 hours and drive on it within 48 to 72 hours. Traditional epoxy systems take longer — usually three to five days before vehicle traffic. We give you a specific timeline based on the system we install and the temperature conditions during the application. Cold weather slows cure time, so winter installs may need a bit more time before vehicle access.
Yes, in most cases. Minor cracks can be filled with a patching compound during the prep stage and will not telegraph through the finished coating. Oil stains can be treated or mechanically ground away during surface prep. Heavily stained or contaminated concrete may require additional steps to ensure the coating bonds properly, which we account for in our assessment. We'll be upfront if a floor has issues that might affect the final result or require extra prep work.
