Garage floor coating in Lafayette, Colorado

Most of Lafayette's housing went up between the late 1970s and the mid-2000s, which puts the typical garage slab at twenty to forty winters old. That is exactly the age where bare concrete starts to show its history: a chalky, dusting surface, surface scaling where mag chloride dripped off the car every January, and dark tire outlines where the car has parked in the same spot for a decade. All of that is prep work, not a reason to skip coating. Diamond grinding takes the weak surface off and exposes solid concrete underneath.

Indian Peaks and Silver Creek have the big three-car garages that make a full-flake floor look like a showroom. Old Town, on the other hand, means tight single-bay detached garages off the alley, often with a slab that was poured long before anyone worried about vapor barriers. Both get the same five steps. The detached garages just get a more careful moisture test, because an old slab with no barrier under it can push water vapor that would lift a coating.

A common Lafayette question is whether a coating can go over an existing sealed or painted floor, since so many of these garages were sealed once in the 1990s. The answer is always the same: we grind it off. A new floor is only as good as what it is bonded to, and thirty-year-old sealer is not something we will gamble a floor on.
