…193 unchanged lines
### Wall protection in clinical and food-service areas shall have a smooth, seamless, nonporous surface; textured or open-jointed surfaces shall not be used in those areas.
−### Infection control is frequently the controlling selection driver in healthcare, ahead of impact rating. {note}
−
−### Surface texture and open joints trap soil and pathogens and are incompatible with hospital cleaning protocols. The surface must wipe down completely and survive repeated exposure to aggressive disinfectants without crazing, discoloration, or loss of finish. {note}

+# Rigid vinyl is the long-standing default for corner guards and rails, but a growing number of health systems mandate PVC-free materials and require PETG biopolymer alternatives. Stainless steel and aluminum are specified where metal aesthetics, maximum durability, or food-service hygiene are required. The material choice should be made explicitly and early because substitution requests at submittal almost always trace back to a missing material-compliance clause. {note}

# Corner Guards {toc}

### Corner guard profile and mounting type — surface-mounted wing-and-retainer, surface-mounted one-piece, recessed flush, or surface retrofit clip-on — shall be specified for each location.
−### The mounting types differ in impact capacity, appearance, and coordination burden. {note}
−
−### The wing-and-retainer type carries the highest impact loads because the cover floats on a continuous retainer and deflects on impact; the one-piece type is simpler and used in lighter-duty areas; the recessed flush type gives a near-flush appearance but requires backing in the wall and is a renovation and coordination liability if specified after the substrate is closed; the clip-on retrofit type is for adding protection to existing walls without a retainer. {note}

## Wing width {note}
### Corner guard wing width shall be selected to cover the expected impact zone at the corner and to coordinate with adjacent finishes.
−### The actual wing dimension shall be verified against the retainer width before coordinating adjacent finishes.
−
−### Wing width is both a protection and an aesthetic decision, and the actual dimension often differs from the retainer width. {note}
−
−### A wider wing protects more of the wall face but is more visually prominent and consumes more of any wall finish that returns into the corner. A retainer slightly wider or narrower than the nominal wing is a frequent source of finish-coordination RFIs, which is why the dimension is verified rather than assumed. {note}

−### Corner guards in corridors carrying beds, gurneys, or tall carts shall extend to a minimum height of 8 ft, or full height, where bed and equipment heights exceed a standard 4 ft guard.

−
−### The substrate at each protected location shall be identified before product selection so that the mounting method and fastener type are compatible with it.
−
### A wall protection product that holds on gypsum board may pull free of glazed tile or fail to anchor in hollow concrete masonry. Identifying the substrate type at each location lets the mounting method and fastener be matched to the actual wall, rather than assuming a single condition throughout. Where the protection lands on an existing wall in a renovation, the substrate is often unknown until demolition and should be field-verified. {note}
