Commercial · St. Louis, MO
If your coating is failing, it usually starts with poor epoxy floor prep, not the topcoat. Elite Epoxy St. Louis has served St. Louis since 2019, providing commercial concrete grinding and shot blasting that builds the right profile for epoxy, urethane cement, and polyaspartic systems.
Epoxy floor prep is where adhesion is won or lost, so we start by evaluating slab condition, contaminants, and coating history. We remove sealers, curing compounds, paint, adhesive residue, and weak laitance using planetary diamond grinders with HEPA dust extraction, or steel shot blasting for fast, uniform texture. Cracks, spalls, and joint edges are repaired with epoxy mortar, polyurea joint filler, or fast-cure patch blends, then re-profiled so the coating goes down on sound, clean concrete.
St. Louis facilities see everything from freeze-thaw moisture movement at exterior openings to oil and deicer salt tracked into docks, bays, and corridors, and those issues must be handled before coating. We test for moisture vapor and alkalinity, then specify the right mitigation when needed, including epoxy moisture vapor barriers or cementitious urethane systems in wet or thermal-shock areas. Finish targets are based on the coating spec, from a smoother grind for thin-film epoxy to a more aggressive CSP profile for heavy-build epoxy, broadcast flake, quartz, or urethane cement with broadcast sand for slip resistance.
Commercial customers choose us because we treat prep as a controlled process, not a quick pass with a rental grinder. You get documented surface preparation steps, calibrated equipment, and crews that understand coating manufacturer requirements for cleanliness and concrete surface profile (CSP), including edge work where failures commonly start. We schedule around production, coordinate containment and dust control, and keep your project moving with clear communication from first site walk to final punch list.
Before we coat, we walk the slab with you to confirm readiness: consistent profile, clean pores, solid repairs, and tight edges at joints, drains, and curbs. You receive a written scope, the planned prep method (grind, shot blast, or a combination), repair details, and the coating system compatibility so there are no surprises when the epoxy goes down. If your project needs specialized steps like scarifying, line removal, or heavy coating demolition, we include it upfront and verify the surface is ready for primer the same day whenever the schedule allows.
Many residential garage floors are completed in 1-2 days depending on repairs, humidity, and the coating system. Cure time varies by product, but we provide a clear schedule for foot traffic and vehicle return in the written estimate.
Sometimes, but it depends on adhesion and compatibility. We typically grind to remove failed coating, then re-profile the slab and rebuild the system with the correct primer and topcoats.
We repair cracks and spalls during prep using crack-chasing, joint cleaning, and patch materials selected for the condition. Some moving cracks can telegraph over time, but proper repair greatly improves appearance and performance.
Standard epoxy can amber with UV exposure. For sunlit garages or exterior-adjacent areas, we recommend UV-stable polyaspartic or polyurethane topcoats to help reduce yellowing and chalking.
Yes. We provide a free written estimate that outlines prep, system options, decorative choices, timeline, and care notes so you can compare apples to apples.
Commercial epoxy floor prep is the foundation for a coating that bonds, cures, and wears the way it should. Whether you are installing a high-build epoxy, full broadcast flake, quartz, or urethane cement, the concrete has to be mechanically profiled, cleaned, and repaired to match the system. Elite Epoxy St. Louis focuses on grinding and shot blasting for consistent results on warehouses, production areas, auto bays, showrooms, medical and retail back-of-house, and facility corridors.
Our epoxy floor prep process starts with a site evaluation of slab flatness, existing coatings, oil saturation, and traffic patterns. We select the right method based on the substrate and spec: diamond grinding for controlled removal and smoothing, shot blasting for an even concrete surface profile across wide areas, or a hybrid approach when edges, patches, and open floor require different tooling. Prep includes detailed edge grinding along walls, columns, and around penetrations, plus cleanup that leaves the surface dust-free and ready for primer.
Concrete repairs are handled as part of prep, not as an afterthought. We route and fill cracks, rebuild spalls, and treat control and expansion joints with materials matched to the system, such as epoxy mortar for rebuilds and polyurea joint filler for joint edges that need durability under wheels. When moisture vapor transmission is a risk, we verify conditions and can incorporate an epoxy moisture barrier or recommend urethane cement in areas exposed to washdown, heat cycling, or aggressive chemicals.
The goal is simple: deliver a clean, profiled, structurally sound slab so your coating system performs for the long haul. If you need epoxy floor prep for a new install, a failed coating removal, or a multi-bay facility that must stay operational, we will build a written plan around your workflow and provide a free written estimate.
Call now or send a request and we will reach out within one business day to schedule your free, no-obligation estimate in St. Louis. We assess the project, review the details, and give you a written quote before any work starts, so you know exactly what to expect.
