Durability is more than a technical rating.
Materials meet hands, shoes, sunlight, rain, cleaning products, furniture, and changing patterns of use. A specification should account for that whole life rather than the appearance of a new sample.
Some surfaces gain character through use. Others reveal every mark. Neither response is automatically right or wrong, but the expectation should be understood before a material is repeated across a building.
Repair matters too. Components that can be refinished, replaced in sections, or sourced locally may remain useful longer than products that depend on a single concealed system.
