The most appropriate finish for walls in heavy traffic public corridors is Type III vinyl wallcovering. This choice is supported by several factors. Type III vinyl wallcovering is specifically designed for environments that experience high levels of wear and tear, making it ideal for public corridors where durability is paramount.

This type of wall covering typically has a higher weight and thickness compared to Type I and Type II options, providing better resistance to impacts, scratches, and general abrasion. It also offers easier maintenance and cleaning, which is essential in public spaces that need to maintain a clean and presentable appearance despite heavy use.

In contrast, while eggshell finish paint offers some degree of durability, it may not withstand the continuous abrasion and impact that occurs in high-traffic areas. Fabric wallcovering, while aesthetically pleasing, is less resilient and much harder to maintain in terms of cleaning and care, making it unsuitable for areas that see high levels of activity. Overall, Type III vinyl wallcovering stands out as the best choice for functionality and longevity in such environments.
