Disinfectants are considered to be effective while wet, using a chemical process, and then loose effectiveness when they dry, they are considered to be effective once they dry. When a surface that has been disinfected, the minute it is exposed to contaminated air, or interacts with new surfaces such as human touch, it looses the status of disinfection. Antimicrobials are sometimes described as durable disinfectants or longer term disinfectants that often leverage a mechanical process to mitigate bacterial growth. The nanospears are not detectable by human touch or naked eye, but they do splice particles that land on the applied structure. The longevity of antimicrobials depends on the chemical blend, manufacture instructions/claims/and surface friction incurred.
Types of Applicators
Electrostatic sprayers are an incredible advancement to the efficiency of spraying. Reduced chemical output and the wrapping effect cuts labor time and creates a more efficient application. The wrapping affect can be seen when spraying a faucet. Traditional sprayers, if you are spraying at the faucet from the stance you'd normally wash your hands, you will only coat the front side of the faucet, leaving the backside dry, similar to the day/night affect when the sun shines on half of the earth. From the same position, an electrostatic sprayer would coat a 360 degree surface, reducing the need to attempt spraying the surface from another angle, or a manual wiping. The key market leaders in electrostatic spraying, Emist and Victory Innovations, both jumped in prices due to COVID19 market demands. These tools have been used by many janitorial companies as their workhorse. Many new models being made overseas have unproven and unknown performance. Many battery powered units have been mislabeled as "electrostatic," when in fact they are just electric.
Pump Spraying & ULV Foggers
Pump sprayers are good at getting product out, however the variance between pump sprayers requires more calibration or research to determine if your sprayer is right for your location. Some pump sprayers dispense so much liquid that the wallpaper, or paint on the wall will spot. Pump sprayers dispense so much liquid that chemical costs will sky rocket. Hand pumps are a solid choice because they're manual, economical, and available, being able to pinch hit when a batter unit goes down, or offering a specialty chemical for certain situations. ULV Foggers, known as "Ultra Low Volume" foggers still dispense much more liquid than electrostatic units, however, they typically are more dependable in applying enough chemical to be effectiveness. Depending on the chemical being used, ULV Foggers may be the right choice for your application.
