The difference between dirty and worn
A line marking covered in dust and tyre residue looks faded, and cleaning it makes it look new again. A line marking that has physically worn away looks identical from a distance, and cleaning it changes nothing except that the remaining paint is cleaner. Distinguishing the two takes a moment on site and it determines whether the right answer is a cleaning task or a marking contractor.
The same applies to floor coatings. An epoxy floor that has become dull from soil responds to scrubbing. An epoxy floor where the coating has worn through to concrete in the traffic lanes will not, and continuing to scrub it does not help. Recording which condition applies, area by area, is what allows a site to budget properly instead of repeatedly paying for a result that is not available.
