Applications

The classic snow-belt scenario. A vehicle comes in loaded with brine and packed slush, it melts into a pool on the low side of the slab, and it sits there for hours at a temperature just warm enough to keep working.

The two failure points are always the same. The perimeter, where the floor meets the wall and there is an open joint for water to run into. And whatever crack has been there since year two, which is now a wet line that freezes and widens every winter.

Decorative broadcast flake earns its keep here for a non-obvious reason: the texture hides brine haze and salt residue between cleanings, and it gives wet-foot traction on a floor people walk across carrying groceries.

Spec: Concrete Mender on all cracks, OR-621 basecoat at 12–20 mil with full flake broadcast, OR-55 topcoat at 6–10 mil. Coved 4 in at the wall base, sealed termination at the threshold.

A working shop floor sees everything a residential garage sees plus solvents, brake cleaner, gear oil, coolant, dropped tooling, and jack stands loaded to several thousand pounds on a footprint the size of a coaster.

Point loading is the real design driver. A floor jack wheel and a jack stand pad concentrate more pressure onto the coating than a vehicle tire does, and they do it repeatedly in the same few places.

Chemical resistance in a shop is also a dwell-time question. Nobody wipes up gear oil immediately — it gets noticed at end of shift. Build thickness buys you that time.

Spec: Concrete Mender on cracks and spalls, OR-621 basecoat at 20–30 mil with aggregate broadcast in the wet and wash zones, OR-55 topcoat at 10–12 mil. Total system 30–45 mil.

Basement garages, walk-out lower levels, and hillside slabs are where moisture goes from a factor to the entire problem. Hydrostatic and vapor pressure act on a below-grade slab continuously, and they do not care what the weather is doing.

These are the floors where ASTM F2170 relative humidity readings matter most, because a calcium chloride test on a cool below-grade slab can read deceptively low while the concrete is holding a great deal of water.

Be honest about what a floor coating can and cannot do. A coating on the negative side of an active water problem is not a substitute for exterior waterproofing or drainage. Where the issue is vapor rather than liquid intrusion, a properly specified system handles it well.

Spec: Moisture testing first, always. Concrete Mender on all cracks, OR-621 basecoat at 20–25 mil, OR-55 topcoat at 8–10 mil, coved at all wall bases. System selection adjusted to the measured RH.

Fire apparatus bays, plow barns, and municipal fleet garages concentrate every problem on this page. The vehicles are heavy, they arrive covered in brine because they are the ones out spreading it, and they are washed inside the building on a regular schedule.

Constant wash-down changes the detailing requirements. Floor drains and trench drains need the coating carried into and through them as a continuous surface, and slip resistance has to be specified for a permanently wet floor rather than an occasionally wet one.

Bay availability is the scheduling constraint — apparatus has to go back in. Work is normally phased bay by bay.

Spec: Concrete Mender on joints and spalls, OR-621 basecoat at 25–35 mil with aggressive aggregate broadcast, OR-55 topcoat at 10–15 mil. Coved at walls, coated into drains and trenches.
