Because the antimicrobial permanently bonds to hard surfaces, it provides continuous control of microbial growth, and will not dissipate or become depleted as long as the surface remains intact. The result is a protected environment long after traditional antimicrobials or sanitizers have stopped working, along with reliable surface protection in between routine cleanings.

The Shield is pre-applied to a material such as ceramic tile or natural stone in a factory setting. The Tile Doctor can work with any supplier that a hospital is contracted with, enabling the hospital to keep their current supply model intact. When the tiles arrive at the hospital, they look no different to the naked eye than any other tiles, yet have a protective coating that has been shown to kill 99.996 percent of MRSA within two hours. By comparison, an untreated tile would enable the MRSA count to potentially double within the same time span.


The value for healthcare facilities actually goes beyond the key antimicrobial properties. The Shield is also eco-friendly, safe for the planet and won’t cause adverse health effects in people. Since the application process permanently bonds the antimicrobial to the material, it’s safe to come in contact with treated surfaces.

“Shield is a broad spectrum antimicrobial,” says Rapp. “It has been tested to be effective against a wide array of microbes, including bacteria and viruses. At the same time, it doesn’t leach harmful chemicals into the environment or off-gas volatile organic compounds. Even more important, it’s not introducing harmful chemicals or compounds to patients with compromised immune systems or weak respiratory systems.”

Another substantial benefit addresses a topic of concern in recent years, the use of harsh cleaners. Organizations like Health Care Without Harm, and even major mainstream news outlets, have reported on the problematic relationship hospitals have with cleaning agents. Some of these cleaners, due to the chemicals used, are classified as toxic, and damage the environment when they’re produced, used and/or disposed of. They also may accumulate in the bodies of individuals who are constantly exposed to them, creating health issues. As with any treatment relying on chemicals to kill bacteria, if it’s not successful — say some bacteria comes into contact with a diluted solution, for instance — there’s a chance for future generations of bacteria to develop a resistance to the chemicals.
