Old Epoxy Removal & Refinishing in Des Moines, IA

What Is Old Epoxy Removal & Refinishing?

Old epoxy removal and refinishing is the process of stripping a failing coating down to bare concrete and reinstalling a proper system in its place. This is different from a simple recoat — when an existing epoxy or paint coating is peeling, bubbling, or delaminating, applying a new layer directly over it almost never solves the problem, because the new coating just bonds to a failing surface underneath.

This service applies whether the original coating was a professional install that failed prematurely, a DIY kit that didn't hold up, or an older coating that's simply reached the end of its usable life after years of wear. In all three cases, the starting point is the same: get back down to sound concrete before doing anything else.

It's worth noting that not every worn epoxy floor needs full removal — a floor that's simply lost its shine or has minor surface scuffing but isn't peeling or bubbling may be a candidate for a fresh topcoat instead. We'll tell you honestly which situation you're in during the free evaluation, rather than defaulting to the more expensive option.

Diagnosing Why the Original Coating Failed

Before we remove anything, we identify why the existing floor is failing, since that determines both the removal method and how we prevent it from happening again. Common causes include inadequate surface prep during the original install (a light acid etch instead of mechanical grinding), moisture vapor issues that were never addressed, a low-quality consumer-grade product, or simply a coating that's reached the end of its service life.

Skipping this diagnosis is how floors end up getting recoated and failing a second time. If the underlying cause — often moisture or poor bonding — isn't addressed, a fresh coating applied the same way will typically fail the same way, just on a slightly different timeline.

This is especially common with garages and basements that had a DIY epoxy kit applied over an acid-etched surface rather than mechanically ground concrete — the coating can look fine for a year or two before the weak bond starts showing as peeling at the edges or in high-traffic areas.

Removal Methods

Depending on the coating and substrate, removal is done through mechanical grinding, shot blasting, or in some cases chemical stripping, followed by a full evaluation of the concrete underneath.

Grinding and shot blasting are generally preferred since they also profile the concrete surface, which is exactly the prep work a new coating needs to bond properly — so removal and re-prep happen as one combined step rather than two separate jobs. Chemical stripping is reserved for situations where mechanical methods aren't practical, though it typically requires more cleanup and doesn't profile the surface the same way.

Once the old coating is off, we inspect the bare concrete for any cracks, spalling, or moisture issues that were previously hidden underneath it — problems that often go unnoticed until the old coating is removed and the slab is fully exposed.

Refinishing With a System Built to Last

Once the old coating is fully removed and the concrete is properly profiled, we address whatever caused the original failure — whether that's moisture mitigation, better surface prep, or simply a higher-grade coating system than what was used originally — before applying the new finish.

This is why removal and refinishing jobs get the same moisture testing and prep standards as a brand-new installation, not a shortcut version. The goal isn't just to make the floor look good again; it's to make sure the new system doesn't fail for the same reason the old one did.

In most cases, this is also an opportunity to upgrade the finish — if the original floor was a basic solid color, refinishing is a natural point to consider a flake or metallic system instead, since the surface prep work is already being done regardless.

Why Professional Diagnosis Matters

Removal and refinishing is one of the areas where an accurate diagnosis matters more than almost anything else in the process — recoating a floor without understanding why it failed the first time is how homeowners end up paying for the same repair twice.

We look for the telltale signs of each common failure mode: bubbling and blistering usually point to moisture, peeling in sheets often points to poor original surface prep, and cloudy or yellowing coatings without physical damage usually point to product quality or UV exposure rather than a structural problem. Each of these gets a different fix.

What to Expect During Your Free Quote

During your free on-site evaluation, we inspect the current coating's failure pattern, test the underlying concrete, and give you a clear diagnosis of what went wrong the first time — not just a price to redo the floor.

From there, you'll get a straightforward removal and refinishing plan, including which system we recommend to prevent the same issue from happening again, so the investment actually lasts this time.
