Coated floors are low maintenance, not no maintenance. The difference between fifteen years and twenty-five is about four habits.
Everyday Cleaning
Dust-mop or soft-broom weekly to remove grit, grit under a shoe or a tire is what actually scratches a floor, not the shoe or the tire. Damp-mop monthly with a pH-neutral cleaner and warm water. That is the entire routine for a residential floor. Commercial floors move to an auto-scrubber with a non-aggressive pad on whatever frequency the traffic demands.
Cleaners to Avoid
Citrus-based cleaners, vinegar solutions and anything acidic will slowly dull a polyaspartic topcoat and leave uneven sheen. Avoid soap-based products too. They leave a film that builds up and looks hazy. Bleach is fine occasionally at dilution but not as a routine cleaner. If a product does not say pH-neutral, assume it is not.
Protecting Against Point Damage
Felt pads under toolbox feet, workbench legs and appliance corners. A sheet of plywood or a mat under a jack stand or an engine hoist. Nothing dropped from height onto a coated floor is a good idea, but a 25-35 mil system has real reserve. The failures come from concentrated static loads on sharp feet, not from occasional impacts.
The Walk-Off Mat Does More Than Anything Else
Most of the wear on any floor comes from grit tracked in on shoes and tires. A three-metre matting run inside a commercial entry, or a simple mat at the door of a garage, removes most of it before it ever reaches the floor. It is the single highest-value maintenance decision and it costs almost nothing.
Dealing With Spills
Oil, brake fluid, gasoline and antifreeze wipe up with no staining if dealt with reasonably promptly. A polyaspartic topcoat is chemically resistant, not chemically immune. The exceptions worth acting on quickly are battery acid and strong solvents left to pool. Road salt should be rinsed off in spring rather than left to sit through summer.
The Re-Coat Cycle
A residential garage floor rarely needs anything beyond cleaning for fifteen to twenty years. A commercial floor in real traffic will want a fresh topcoat around year ten. Re-coating is a one-day job, light abrasion, clean, two coats, and it does not disturb the flake or metallic layer underneath. Doing it before the topcoat wears through to the decorative layer is what makes it a cheap job instead of a rebuild.
