Coatings that are damaged by the wrong choice
Anti-slip floor treatments lose their profile if cleaned with the wrong product or the wrong pad, which is a safety consequence rather than a cosmetic one. Epoxy coatings can be dulled or softened by strong solvents. Powder coating discolours under aggressive alkalis. Stainless steel marks permanently with chloride-based cleaners. None of these failures is obvious at the time, which is what makes them common.
The pattern is consistent: the damage is cumulative and appears months after the decision that caused it. By then the product has been in use long enough that nobody connects the two. Recording the approved products at the outset, with the reasoning, is the only reliable defence, because it removes the possibility of a well-intentioned substitution. A coating replaced early is a far larger cost than the entire annual cleaning arrangement that damaged it.
