Service life
How long does a floor coating last?
The service life of a coated floor comes down to the prep under it, how much film went down, and what the floor gets asked to do after that.
The short version
- Clear View Surface Solutions publishes 15 to 20 years or more.
- Prep sets the ceiling. A coating cannot outlast its grip on the slab.
- Film thickness is what takes the wear, so a heavier build has more to give up than a thin one.
- Sun on the surface, tires turning in the same spot, and road salt are what age a floor fastest here.
- A top coat can be renewed before the color layer under it is worn through.
What the life depends on
Prep sets the ceiling, and nothing put down later raises that ceiling back up. A coating that keyed into a ground slab wears from the top down, slowly, the way it is meant to. A coating on a slab that was never opened up gets to fail a different way, from the bond line, and that failure does not wait for the surface to be used up.
After that it is film and use. Thickness is what stands between the traffic and the concrete, so a heavier build with a real top coat over the flake has more to give up than a thin one does. Then the room itself: a floor with two vehicles turning on it daily is being asked for far more than a basement nobody drives on.
Clear View Surface Solutions publishes 15 to 20 years or more, and that figure is worth reading next to the prep and the build holding it up rather than on its own, because the same system on a slab that was never opened up is a different floor.
What ages a floor in the southwest Twin Cities metro
Salt and meltwater do the most work here. A vehicle comes in loaded with brine and slush, it thaws onto the floor, and it sits in the low spots and along the joints until it dries or gets pushed out the door. A coating is built for that, and it is still the thing on your floor for more hours of the year than anything else.
Then there is the turning. Wheels cranked over while the car is barely moving grind at one spot instead of rolling across it, so a floor wears in arcs where people back out. And sun, wherever it reaches, which is usually a strip inside the overhead door and anywhere a window puts light down on the floor.
Renewing the top coat
The top coat is the part that meets everything, and that is on purpose. It is also the layer that can be taken back off and put down again without touching the color and flake underneath. A floor that gets that done while the color layer is still sound is a far smaller job than a floor that waited until the flake was showing through.
What to watch for is a dulling in the traffic path, a chalky feel where the sun lands, and flake that starts to feel sharp underfoot instead of smooth. Those say the top coat is doing its job and getting near the end of it. Have somebody look at the floor before it goes past that point.
