Applying disinfectants to surfaces is a crucial step in reducing the spread of COVID-19 and ensuring a safe and clean environment. Touchpoint cleaning should be complemented by the use of antimicrobial solutions to effectively eliminate microorganisms on walls, floors, and horizontal surfaces. However, it is essential to select the appropriate materials and methods that are compatible with the building’s use and any energy or environmental efficiency ratings it has obtained.

There are various processes and systems available for large-scale sanitization. Many antimicrobial products used in industries such as restoration, medical, and food service can be utilized by adjusting the application method. This can include using pump sprayers, misting equipment, airless sprayers, electrostatic sprayers, ultralow volume (ULV) foggers, or thermal foggers. Before employing any alternative application method, it is important to review the product label to ensure that it is registered and approved for that specific method.

Antimicrobials and disinfectants should be used if they are approved by the EPA or FDA for surface sanitization, listed on the EPA’s “Emerging Pathogen/List N,” or meet the requirements for enveloped viruses like SARS-CoV-2. Prior to applying disinfectants, certain steps should be taken, such as covering return air vents to prevent the disinfectant from entering equipment or other areas. It is also recommended to open doors or windows to reduce airborne droplets, as suggested by the CDC.

Using HEPA filtered negative air machines as air scrubbers can help reduce airborne particulates during the treatment process. Once an approved disinfectant product and application method have been selected, the disinfectant should be applied according to the label directions. If walls are considered potential touchpoints, they should be included in the application. Starting at the designated upper height, the disinfectant should be applied in overlapping passes, ensuring thorough coverage of every part of the surface.

The number of treatments and the duration of the disinfectant’s contact time will depend on the product’s instructions and the application method used. Careful assessment of surfaces is necessary to prevent streaking or running while maintaining the recommended contact time. Floors and other horizontal surfaces should be treated after the walls, and visible debris should be removed before application. Regular vacuuming, dust mopping, or sweeping is not recommended for cleaning to prevent COVID-19 transmission. When applying disinfectant to floors, it is important to follow a pattern that allows the operator to finish at an exit without walking over the wet floor.
