Garage Epoxy Coatings
in New Orleans
Coastal slab conditions demand a different approach. Flake, solid-color, and polyaspartic systems installed by the crew behind Louisiana’s largest commercial epoxy projects.
What the Gulf Coast Does to a Concrete Slab
New Orleans concrete sits on expansive clay soils that shift with the water table, and the city’s humidity is among the highest in the country year-round. Both factors affect garage coatings in ways that don’t apply to inland markets. Slab movement from soil expansion and contraction creates micro-cracks over time, and moisture vapor emission from coastal slabs is typically higher than what labs test for in controlled conditions. An epoxy system installed without vapor testing and a compatible primer on a New Orleans slab is on borrowed time.
We test every slab before any coating goes down. Surface temperature, moisture vapor emission rate, and crack mapping are part of our standard pre-installation process. If the slab has issues that need addressing before a coating will hold long-term, we tell you before we start rather than finding out after the coating fails at year two.
Systems We Install for New Orleans Garages
- Flake epoxy. The most requested residential system. Vinyl flakes broadcast into the wet base coat give a multi-tone texture that holds up under daily vehicle and foot traffic. See our flake epoxy page for the full breakdown.
- Solid-color epoxy. A clean, single-tone surface. Popular with homeowners who want a precise aesthetic and with commercial garages that need a professional look without the decorative texture.
- Polyaspartic topcoat systems. Faster cure, better UV resistance than standard epoxy (less yellowing in the coastal sun), harder finished surface. We typically run epoxy as the base and polyaspartic as the topcoat. See our polyaspartic coatings page.
How We Prep and Install
Shot blasting or diamond grinding to an ICRI CSP 3 to CSP 5 profile. Cracks filled with rigid epoxy filler. Moisture-tolerant primer applied based on test results. Base coat, decorative layer if specified, polyaspartic topcoat. We do not use acid etching as a standalone prep method. It leaves chemical residue and does not create the mechanical profile required for coatings we warranty in this climate. Every installation is prepped to the same standard regardless of whether it is a 400 square foot residential garage or a 10,000 square foot commercial bay.
Older New Orleans housing stock adds a wrinkle you don’t get in a new subdivision. A raised garage under an Uptown home, a slab poured decades ago behind a shotgun double, or a converted carriage space can have layers of old paint, tile mastic, or a previous failed coating still stuck to the concrete. Grinding those off is part of the job, and it is slow work, but skipping it means the new system bonds to the old failed layer instead of the slab. We take the floor down to sound concrete before we prime, even when that means an extra day on the grinder. That is the honest way to get a floor that lasts on an old slab.
Vapor is the quiet killer down here. In a city where a lot of ground sits below sea level and the water table is high, the concrete is pulling moisture up from underneath around the clock. We check the moisture vapor emission rate and relative humidity inside the slab before we pick a primer, and if the numbers are high we run a moisture-mitigation primer that is built to hold back vapor pressure. A standard primer under those conditions is where you get the bubbling and the peeling that gives epoxy a bad name in New Orleans. Matching the primer to the actual reading is the whole ballgame.
We also lean on polyaspartic more heavily in this market than a contractor in a dry climate would. It cures fast, which matters when afternoon storms mean you cannot count on a long dry window, and it takes the coastal UV and the constant damp better than straight epoxy. On a typical New Orleans garage we run an epoxy base for adhesion and a polyaspartic clear on top for wear and to lock the flake, so the floor is walk-on quickly and back in service without a long shutdown. When a storm is coming and you need the garage buttoned up, a fast-cure topcoat is not a luxury, it is the difference between finishing and stopping.

Garage Coatings in New Orleans FAQ
Why does epoxy delaminate so often on New Orleans garage floors?
The usual culprit is moisture vapor coming up through the slab combined with inadequate surface preparation. Coastal concrete has elevated vapor emission rates, and applying a coating over a slab that exceeds the product’s moisture tolerance creates a vapor barrier failure point. We test before we coat. Call (225) 456-9224 if you have a failed floor that needs a proper assessment.
How long does a garage floor coating take in New Orleans?
A typical two-car garage runs two to three days: prep and prime on day one, base coat and decorative layer on day two, topcoat on day three with cure time before vehicle use. We give a specific installation schedule when we scope the project.
Does the heat in New Orleans affect epoxy installation?
Yes. Slab surface temperature affects pot life and penetration depth. We schedule installations to manage surface conditions. Applying epoxy to a slab above the product’s maximum application temperature results in a weaker bond and can cause outgassing. This is especially relevant during New Orleans summers where slab temperatures can run significantly higher than air temperature.
Can cracks in my New Orleans garage floor be coated over?
Small shrinkage cracks can be filled with rigid epoxy filler as part of the prep process. Cracks showing active movement or patterns consistent with soil settlement warrant a structural assessment before coating. We flag these during the pre-install inspection and will not coat over a slab with active movement problems.
What does garage floor coating cost in New Orleans?
Pricing depends on square footage, slab condition, and system selection. We provide a free, itemized price with no obligation. Call (225) 456-9224 or submit our contact form.
If my garage flooded during a storm, can it still be coated?
A slab that has taken on floodwater can usually be coated once it has fully dried and we have confirmed the moisture readings are back within spec. The key word is fully. Concrete holds water for a long time after a flood, and coating a slab that is still releasing moisture guarantees a failure. We test, and if the slab needs more time to dry we tell you that instead of rushing it. If the flooring under a prior coating trapped moisture and lifted, we grind it back to bare concrete and start clean.
Do you coat garages in older Uptown and historic New Orleans homes?
Yes, and we do a fair amount of it. Older homes often have raised garages, converted spaces, or slabs with old finishes still bonded on. We grind those down to sound concrete, deal with any settlement cracks, and select a primer that suits an older, more porous slab. The prep takes longer on a historic property than on a fresh pour, and we build that into the price honestly rather than cutting corners to hit a low number.
Will the coating handle salt air and constant humidity year-round?
A properly installed epoxy base with a polyaspartic topcoat is well suited to the coastal environment. The polyaspartic resists the UV and does not yellow the way older clear epoxies do, and the sealed, seamless surface does not let the damp soak into the concrete. What kills coatings here is not the salt air itself, it is moisture coming up from below through an untreated slab. We handle that at the primer stage, which is why our garage floors hold in this climate.
