We are professional house painters (Dr. House Painter) who give excellent finishes as required of us. We mix match, match, and apply paints on houses and various houses. Because of the growing demand for healthy living we use materials capable of killing microbes on surfaces that are frequently touched by people in our everyday lives. We are using the best antimicrobial paint, Paint Shield® from Sherwin Williams. The paint has a high-quality coating performance, magnificent hide, and is long-lasting.

Paint Shield®
Paint Shield® is an antimicrobial paint that has added additives that make surfaces painted using the paint resistant to microbes such as fungi, viruses, and bacteria. Sherwin Williams Paint Shield® kills 99.9% of bacteria within two hours of exposure on a painted surface.

The paint is the first EPA registered and its formula is patented in the US. Sherwin-Williams Paint Shield ® has passed the rigorous EPA test protocol that is conducted by third-party labs. It went through rigorous scrubbing tests and repeated exposure tests to test its effectiveness after being exposed to normal wear and tear, cleaning and scrubbing. After the rigorous tests, the Paint Shield ® still maintained its effectiveness up to four years as long as the integrity of the surface painted is maintained. Sherwin-Williams Paint Shield ® is effective and meets high-quality standards. The paint was tested for:

Longevity test: The ability of Paint Shield ®to kill microbes over time, Paint Shield passed the test as it remains effective for up to four years if the surface integrity is maintained

Continuous-kill test: Paint Shield ® has the capacity to kill microbes continuously at the rate of 90% even after repeated contamination offering an effective means of combating microbes on Paint Shield ® painted surfaces.

Washability test: Walls painted with Paint Shield were exposed to rigorous washing, cleaning, and scrubbing, using various cleaning products and protocols in health care facilities. The paint passed the continuous-kill tests after the application of the cleaners and scrub test.

Toxicological review: All the ingredients used in Paint Shield ® are on the EPA inert ingredients approved list and they comply with the environmental and human health guidelines.

Benefits of Sherwin-William Paint Shield ®

Microbicidal Paint is effective in killing disease-causing germs making it an appealing disease prevention intervention especially for those with vulnerable immune systems. The paint has the ability to inhibit the growth of mold and mildew leaving the walls and surfaces looking better and clean. In addition, the paint is long-lasting and helps in preventing allergy symptoms for many people. On the other hand, Sherwin-Williams Paint Shield ® is environmentally friendly and can be used on nearly all kinds of surfaces whereby all the surfaces painted show excellent antimicrobial properties by killing disease-causing microorganisms such as Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. coli).

The use of antimicrobial paint helps prevent the spread of microbes that can cause diseases especially in hospital settings where many people have weak immune systems. They have the potential to lower the environmental impact of cleaning using different chemicals or detergents, therefore, reducing the need and costs in maintaining facilities.

Moreover, the use of antimicrobial paints is increasing rapidly though quietly and is designed to inhibit the growth of microbes on various surfaces. Surfaces capable of killing bacteria upon contact have generated significant attention and has seen a surge of interest in recent years. Sherwin-Williams Paint Shield ® is applicable and remains active for multiple challenges even when exposed to various cleaning scenarios that they might encounter. Sherwin-Williams Paint Shield ® is made of quaternary ammonium compounds, a common disinfectant. The use of exclusive patented technology in manufacturing the paint represents the culmination of extensive research of scientists and microbiologists.

Where can Paint Shield ® used

Initially, the paint was developed for health care facilities, athletic facilities, schools, and other specialized business settings. However, Sherwin-Williams Paint Shield is not only suitable for hospitals and day-care centers, but can also be applied in kitchens, bathrooms, and laundry rooms. Walls that are more likely to be exposed to microbes due to the higher moisture content that makes the environment hospitable for viruses and bacteria and the surfaces are most likely to be contaminated. The paint is also applicable like other interior paint and is used on ceilings, walls, doors, and on trims.

Microbes susceptible to the Paint

Sherwin-Williams Paint Shield ® kills 99.9% bacteria including Staphylococcus aureus, E. coli (Escherichia coli), Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococcus faecalis (VRE), and Enterobacter aerogenes on painted surfaces. The paint skills the microbes within two hours of exposure and continues to kill 90% of the microbes for up to four years if the integrity of the painted surface is maintained.

Advantages and Disadvantages of using Sherwin-Williams Paints

Currently, only Sherwin-Williams Paint Shield® is the major paint offering microbicidal properties, in addition, Sherwin-Williams offers other varieties of over 500 colors with different shades. It has a germ-killing capacity that offers protection against disease-causing microbes. However, the Paint Shield ® comes in the eggshell finish only, therefore, not appropriate for flat walls with semi-gloss trim. Consequently, most of the microbes thrive in moist or humid environments and less common on drywalls, hence, most people do not encounter germs on their walls.


Sherwin-Williams Paint Shield ® helps to inhibit the growth of microbes on painted surfaces with a rate of 99.9% of Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli (E. coli), Vancomycin-resistant Enterococcus faecalis (VRE) and Enterobacter aerogenes within two hours of exposure. Consequently, it has a continuous-kill capability of 90% of bacteria for up to four years if the integrity of the painted surface is maintained. Paint Shield ® is not only ideal for health care facilities and daycare centers, but can be used in athletic facilities, schools, senior care facilities, residential housing, and cruise ships. The paint can be applied to interior hard, non-porous ceilings, walls, doors, and trims. In addition, homeowners can benefit from Paint Shield ® that meets the high-quality standards and the benefit of working with professional painters in Miami, Florida.
