What We Put Down
Most garages here get a flake build: base coat, chip broadcast into it to refusal, then a clear polyaspartic over the top. The grip matters more than people expect, because a garage floor is wet for a good part of the year from melt off the vehicle alone, and a smooth gloss floor in a working garage is a hazard rather than a feature.
We take the coating right up to the door line and finish it square to the track. That is deliberate. The door line is exactly where salt and meltwater collect, and a floor that stops a foot short is a floor that starts failing there first. Steps, landings and service door thresholds get coated too.
Preparation Is Most Of The Work
The slab is ground with diamond tooling, never acid etched. Cracks get cut out and filled, spalled patches are rebuilt, and oil contamination is ground out or, where it has gone deep, cut out entirely. We vacuum continuously while grinding so the dust stays in the machine instead of drifting into the house.
We also take a moisture reading before pricing it. Garage slabs in Chatham-Kent sit on heavy clay that holds water against the underside of the concrete, and a slab that reads wet needs a different primer to one that reads dry.
Timing
Foot traffic is normally fine the next day. Vehicles wait longer, and in January that is a real variable rather than a formality, since we work to the temperature of the slab rather than the air. Whatever the date turns out to be, it is in writing before we start.
