G4S invests in Signo Nano-Care surface coating against SARS CoV-2

The product has been tested using real life ATP swab testing, carried out by G4S in conjunction with Liquid Guard manufacturer

G4S has supplied and applied Signo Nano-Care’s permanent bond anti-microbial coating, Liquid Guard, to high-touch points within a number of key buildings in the UK.

The results of combining nano-coating technology with a long-acting antimicrobial agent, the company claims, is a permanently bonded coating that kills microbes that meet the surface. G4S says the product has been independently proven to be effective against a range of bacteria and enveloped viruses, including SARS CoV-2 and influenza A. Due to its long-term antimicrobial activity, (recommended to recoat every 12 months) it can be a suitable coating for workstations, communal areas, touch screens, door /elevator keypads and IT equipment.

The product has been tested using real life ATP swab testing, carried out by G4S in conjunction with Liquid Guard manufacturer Signo Nano-Care.

Through the controlled measurement of microbial activity across a range of hard surfaces and textiles before and after the coating application, G4S’s in-house health and safety team was able to present verification to their clients that Liquid Guard had met the claims of its manufacturer.

As many ‘non-essential’ businesses look forward to the return of their employees in varying bubbles and work groups, maintaining a COVID-19 secure environment will be a necessity for many months to come. By adopting technologies that continue to be evaluated and proven in the field, facilities managers and businesses can have confidence that their surfaces are not a source of recontamination.

Simon Mercer, Signo-Nanocare’s MD said: “Liquid Guard has an invaluable role in actively helping to break the transfer of transient microbes via hand-surface-hand contact, especially in high touch areas that are hard to clean between touches. By using Liquid Guard extensively G4S have been able to reduce the excessive extraordinary cost of moment-in-time multiple surface cleans and fogging that had been employed in large facilities, as it delivers a constant background kill of SARS CoV-2 and its variants”.
