Spray Disinfection
of Surfaces

Spray Disinfection of Surfaces: Why you should spray disinfectant?

In addition to direct human-to-human transmission, contaminated surfaces also pose a risk of transmitting viruses and pathogens. Especially in the current COVID-19 pandemic, this is of great importance: Studies show that SARS-CoV-2 viruses can survive for several days on surfaces that we come into daily contact with.

The WAGNER Group is a global expert in surface coatings. Our mission: We bring colour, protection and function to surfaces.

This makes us the ideal partner when it comes to disinfecting surfaces. With our mobile spraying units, the most common disinfectants can be applied to surfaces quickly, easily and even over large areas. In this way we support people through our innovation and contribute to an effective reduction of the spread of viruses.

Where can spray disinfection be used?

Particular attention must be paid to areas in daily use, as well as to areas frequented by people who are or were already ill.

  • Locker Rooms, Bathrooms, (Sanitary facilities)
  • Office Spaces
  • Restaurants and food preparation areas
  • Education facilities
  • Public transport
  • Public amenities, entryways and public spaces

What can be disinfected?

  • Spraying technology allows a comprehensive surface coating with disinfectant – subsequently the microbial presence of bacteria, fungi or viruses can be reduced.
  • Disinfectants in liquid form, which are at least limited virucidal, are suitable for application to surfaces by spraying.
  • Disinfectant types: Based on alcohol, aldehydes, biguanides, bisphenols, diamidines, peroxygens, phenolics, quaternary ammonium salts and halogen-releasing compounds.
  • You can find further information on the page of the John Hopkins University.

For whom is spray disinfection suitable?

The Spraying of Disinfection solutions is commonly undertaking by the following groups:

  • Cleaning & Sanitation Providers
  • Health and Care Providers
  • Municipality Workers
  • Janitors, Commercial and Residential Facility Managers
  • Safety authorities: Military and Reservists


How does spray disinfection of surfaces work?


  • Tighten the connections on the device fi rmly and check the seal of the device with water before using it with disinfectant.
  • Evacuate the water.
  • Fill disinfectant into the hopper or place suction system directly in the material container.
  • For FLEXiO units:
    • maximum air setting with low material setting
  • For airless devices:
    • Pressure setting: 70-100 bar (Control Pro Level 4)
    • Nozzle selection: (recommendation 513, 311 for Control Pro)
    • When using other nozzles, the application speed must be adjusted
  • Apply disinfectant quickly and evenly to the surfaces according to the material recommendations.
  • Please refer to the manufacturer‘s instructions for exposure times of the disinfectant you are using.

Safety Instructions

Please observe the following safety instructions before use:

  1. Always wear the necessary personal protective equipment („PPE“, see safety data sheet of the device: gloves, goggles and mask).
  2. Never point the fluid stream at people or animals – there is a risk of injury.
  3. Thoroughly read the operating instructions of the machine as well as the safety data sheet of the material and follow the instructions contained therein.
  4. Do not spray any electrical devices and equipment.
  5. When using fl ammable liquids, the machine must be operated outside the room where the spraying occurs (danger zone = 5 m distance from the application area).
  6. If flammable disinfectants are used, sufficient ventilation must be ensured. Furthermore, no warm or hot surfaces are to be disinfected. If possible, electrical systems should be switched off and light switch operations prevented. There is a risk of explosion!

The following points must be fulfilled before you use the device.


Use alcohol-based disinfectants only with airless sprayers (e. g. Control Pro / ProSpray / SuperFinish).

Flush the system thoroughly with water immediately after use or during work interruptions! Ensure that there is no remaining disinfectant liquid
in the unit after use!

Legal, regulatory and normative requirements must be observed!
