Antimicrobial protection against bacteria, algae, fungi, mold, mildew, and yeasts

The coronavirus pandemic (COVID-19) has focused attention on virus protection and ways to create healthier home and work environments. As people search for solutions, they are finding a technological innovation that can control bacteria, fungi, algae, mildew, and yeasts. Tile Doctor Shield® is a non-toxic, antimicrobial product approved for hard surfaces that is effective against a broad spectrum of microbes.

Implementing a Sustainability and Wellness Strategy

Microbes are microorganisms. Too small to be seen, the microbes can be bacteria, viruses, and fungi. While some microbes are important for our health, others are tiny, living things that can cause health problems, such as malaria, toxoplasmosis, diarrhea, colds, or tonsillitis. They've also been traced to the flu, measles, and other more serious illnesses.

Antimicrobial sprays and wipes can help manage the growth of microbes as can EPA-registered disinfectants. However, to be effective, you have to be vigilant. While these products can inactivate bacteria and viruses, they do not provide any lasting protection. If someone touches these surfaces after they have been disinfected, they can become re-infected.

On hard surfaces, viruses can be active for extended periods. A study by the National Institute of Health (NIH) and the Center for Disease Control (CDC) found acute respiratory syndrome coronavirus 2 (SARS-CoV-2) active for 2-3 days on some surfaces, such as plastic and stainless steel.

Tile Doctor Shield® can deliver additional safeguards against such microbial contamination on both horizontal and vertical surfaces. This extra level of protection helps extend the life of the installation and provides a more sanitary surface between cleanings. It also helps to avoid odors and stains.

Tile Doctor Shield® eliminates the need for harsh cleaners, contains, no volatile organic compounds (VOCs)., and does not leach. Here's why that's important.

Volatile Organic Compounds (VOCs)

Many household products and building materials contain VOCs. The Environmental Protection Agency (EPA) has done extensive research that shows these volatile organic compounds are emitted as gases from certain solids or liquids. VOCs contain a variety of chemicals. Some of these chemicals can cause short-term and long-term health effects – especially when used indoors.

The EPA reports note health effects that may include eyes, nose, and throat irritation, headaches, loss of coordination, nausea, and damage to the liver, kidney, and the central nervous system. Some VOCs are suspected (or known) to cause cancer in humans.


Some hard surface and grout products use silver-based antimicrobials. These rely on silver nanoparticles, which can retard the growth of mold and mildew. Unfortunately, these particles tend to leach in relatively short periods. One study treated clothing with silver antimicrobials. After just three washings, 43% had leached out the clothing. After 10 washes, only 2% remained. Even on hard surfaces, it leaches.

Not only did this reduce the effectiveness to near zero, but it also washed these silver particles down the drain and into the water treatment system. Although the impact on the ecosystem is unknown, some assessments rate these particles as very high for aquatic toxicity.

Some hard surfaces products that claim to be effective against microbes use silver, heavy metals, triclosan, and other chemicals that leach and can emit low doses of toxins. Once these chemicals are depleted, they lose their effectiveness.

A Mechanical Barrier of Antimicrobial Protection

This gets a little technical, but it's an important point. Other products using silver or other heavy metals control microbes by poisoning them. As we've shown, however, once the product leaches, it no longer provides much protection.

Tile Doctor Shield® provides a mechanical barrier of antimicrobial protection. When microbes come in contact with Tile Doctor Shield®, cell membranes are physically disrupted. Microbes are drawn to the surface with a magnetic force, which ruptures the cell walls. The surface becomes inhospitable to a broad spectrum of bacteria, algae, and fungi. There is no chemical left for the microbes to feed on.

Here's another important point. Tile Doctor Shield® permanently bonds to hard surfaces to provide a built-in system of protection. It will not dissipate, becoming depleted, or leach as long as the surface remains intact. This results in a protected environment that continues to work after traditional antimicrobials or sanitizers have stopped working. It also provides reliable surface protection even in between cleanings.

Easier to Clean

Tile Doctor Shield® repels water. This simplifies cleaning as the surface easily released stains and prevents hard water and soap scum buildups. In most cases, a neutral cleaner will keep your treated surfaces clean. Limiting the use of harsh cleaning products that are needed means fewer chemicals go down the drain.

About the Tile Doctor Shield®

Tile Doctor Shield® is based on a unique antimicrobial technology that is built into hard surfaces and grouting products. This provides superior control of bacteria, fungi, algae, and yeasts on a variety of surfaces and substrates. Its active antimicrobial ingredients are registered with the EPA and similar regulatory bodies throughout the world.

The molecular design of the underlying technology has been meticulously field tested and has been used safely for more than 4 decades. The chain of molecules has been formulated precisely for maximum effectiveness.Tile Doctor Shield® permanently bonds to hard surfaces and grouting products, effectively controlling a broad spectrum of microbes for the life of the treated surface. Because it is a bonded material, it will not rub off or migrate onto the skin.

It is recommended for use on horizontal and vertical surfaces in homes, hospitals and medical facilities, schools and universities, office buildings, restaurants, and other public areas.

Tile Doctor Shield® was recognized in 2011 for its innovative approach when it earned the prestigious Edison Award for Best New Product. These awards are named after Thomas Edison and judged on four criteria: Concept, Value, Delivery, and Impact. As an Edison Award winner, Tile Doctor Shield® joined the ranks of other Edison Award winners, such as the Apple iPad, the Keurig single cup brewing system, and Tesla CEO Elon Musk. In 2018, Tile Doctor Shield® was granted a patent from the U.S. Patent Office to protect its unique application process.
