Lexington Park exists because of Naval Air Station Patuxent River, and the town’s concrete tells that story in layers. The original wartime and post-war housing that went up to serve the base is now eighty years old. The contractor and defense-services build-out that followed is newer. And the current round of construction is newer again. Three eras of slab, sometimes on the same street.
The mid-century stock is where the moisture work is. Slabs from that period went down before vapor retarder sheeting was routine, on coastal-plain soil with a high water table, and they have been drawing ground moisture up ever since. A homeowner in one of these houses has often already tried a floor coating once, from a box, and watched it bubble and peel inside a year. The product was not the problem. The slab was pushing vapor and nothing was specified to stop it. That gets solved with a relative-humidity probe test and a vapor-barrier primer rated to the number that comes back, not with a better topcoat.
Lexington Park also has a rental share well above what you would find in the rest of St. Mary’s, which changes what makes sense. A landlord coating a garage or a basement is buying a floor that cleans easily between tenants and does not need attention for years. That points toward a full flake broadcast with a durable topcoat rather than anything decorative, and toward a system that can be recoated later without a full teardown.
The third category here is light-industrial and contractor space along the corridor running toward the base gates. Shop bays, service floors, and storage space in this stretch see hard-tire traffic, fluid spills, and equipment that gets dragged rather than lifted. Those floors get specified around point loading and chemical exposure, and they get phased so the space does not lose a full working week. The downtime question usually decides the system before durability does.
One local detail that matters more here than inland: salt. Vehicles working near the water and the flight line carry more salt onto a slab than a suburban commuter does, and salt in a porous concrete surface accelerates spalling. A sealed floor stops the concrete from absorbing it in the first place.
