What drives the decision
It is most attractive where repeated scratching is plausible and replacing the substrate is expensive.
What changes the budget
Budget initial film plus periodic localized replacement and access outside normal business hours.
Operations and lifecycle
Keep product/location records so future damaged sections can be matched quickly.
Planning boundary
Film does not prevent all damage; use products approved for the exact surface.
Educational planning only. Actual construction, code compliance, regulated systems, hazardous materials and safety-critical work require qualified professionals and current local requirements.
