The spread of viral and bacterial pathogens mediated by contact with surfaces is a leading cause of infection worldwide. COVID‐19 and the continuous rise of deaths associated with antibiotic‐resistant bacteria highlight the need to impede surface‐mediated transmission. A sprayable coating with an intrinsic ability to resist the uptake of bacteria and viruses from surfaces and droplets, such as those generated by sneezing or coughing, is reported. The coating also provides an effective microbicidal functionality against bacteria, providing a dual barrier against pathogen uptake and transmission. This antimicrobial functionality is fully preserved following scratching and other induced damage to its surface or 9 days of submersion in a highly concentrated suspension of bacteria. The coatings also register an 11‐fold decrease in viral contamination compared to the noncoated surfaces.
