Why are holey and cracked surfaces such as walls, floors, and countertops not allowed in the salon or school?

The presence of holey and cracked surfaces in a salon or school creates significant challenges in maintaining proper hygiene and sanitation. Such surfaces are difficult to thoroughly disinfect due to the irregularities and crevices that can harbor bacteria, dirt, and other contaminants. Ensuring a clean and safe environment is crucial in cosmetology settings, where clients expect high standards of cleanliness. Consequently, having surfaces that cannot be easily disinfected jeopardizes the health and safety of clients and staff alike, underscoring the importance of smooth, non-porous surfaces that can be effectively maintained.

While other factors like aesthetics or liability risks may be relevant considerations, the primary reason for disallowing damaged surfaces is the inability to properly disinfect them, which directly impacts health standards in these facilities.
