LaPlace at a glance

The largest community in St. John the Baptist Parish, upriver from Kenner along the I-10 corridor. Calls itself the Andouille Capital of the World. Airline Highway runs through it.

Many homes here are slab-on-grade with attached garages, and many were repaired after Hurricane Ida in 2021.

The garage, after the repairs

A garage that served as a staging area during repairs usually carries the evidence: paint drips, joint-compound splatter, tile adhesive, tar from roofing material, and gouges from dragged equipment. None of that can stay under a coating. The sequence that works:

  1. Scrape off the heavy residue, then diamond grind the whole slab to clean concrete.
  2. Read the slab for moisture. Moisture in a slab can make a floor coating fail after it goes down, which is why coating makers generally require a moisture test first.
  3. Fill gouges, cracks, and spalls, then grind the repairs flush.
  4. Prime to the reading, then base coat, flake, and a clear topcoat.

A two-car garage with flake epoxy runs about $2,500 to $5,500, and a single-car about $1,500 to $3,000. Residue removal and repair are the lines most likely to move it. Foot traffic after about 24 hours; vehicles after three to seven days on an epoxy topcoat, or 24 to 48 hours on a polyaspartic topcoat.

Kitchens and food businesses

Local food businesses have kitchen and prep floors, and those are a different problem from a garage. Hot water, steam cleaning, grease, and constant wet traffic will crack or lift a standard epoxy floor.

  • Urethane cement is the usual answer where floors see hot wash-down. It tolerates heat and thermal shock that epoxy does not.
  • Cove base carries the floor up the wall a few inches so the corner can be cleaned instead of collecting grime.
  • Texture is built into the floor for grip when it is wet and greasy.
  • Slope to drains is checked and kept, so water does not pond.

Commercial floors run about $4 to $12 per square foot, with small rooms at the higher end. Ask the local health inspector what the floor must meet before you choose a system. The commercial epoxy flooring page goes further.

Storefronts on the highway

Retail and service businesses along the main roads usually want a floor that looks clean and reopens fast. A flake or solid-color system with a polyaspartic topcoat can often go down over a weekend.

Before the coating crew arrives

A few decisions are easier to make before the floor is ground than after. Are the garage walls getting new drywall or paint? Do it first. Is the water heater or freezer staying on the slab? Ask whether the installer will work around it or needs it moved. Is any section of the slab new concrete from the repairs? Tell the installer when it was poured, because fresh concrete needs time to cure before it can be coated.

Choosing a color that hides repairs

A slab with patched gouges and filled cracks rarely looks uniform under a solid color, even when the repairs are sound. A full flake broadcast in a medium tone disguises them best. If you want a cleaner look, ask whether the installer recommends a skim coat to even out the surface before the color goes down.
