Introduction

The Covid-19 pandemic has highlighted the fact that simply achieving a visibly-clean environment is no longer enough. Effective infection control is now required to eliminate the micro-organisms that we cannot see, to protect the health of everyone in our community.

Liquid Guard® is a revolutionary, award-winning surface treatment providing permanent anti-microbial protection against viruses (including coronaviruses), bacteria, algae and mould.

Liquid Guard was developed in 2019 and won the German Innovation Award in Berlin last year. It is now distributed in 70 countries.

Tested and proven to be safe and long lasting, this award-winning surface treatment is now available in New Zealand through Micro Surface Solutions NZ. Liquid Guard® is unique and superior due to its longevity – requiring re-treatments much less frequently than other surface treatments.

Liquid Guard® coats surfaces with an ultra-thin layer of modified silicon dioxide glass, containing positively-charged nitrogen atoms which attract negatively-charged atoms in microbes. Microbes are drawn to the surface, where Liquid Guard® technology physically kills the microbes through contact with ‘swords’ on the coated surface, each measuring 150 nanometres in size. These ‘swords’ puncture the cell wall on contact and render the microbe dead.

What sets Liquid Guard® apart is that it is ‘always on’, working continuously to kill all microbes that land on treated surfaces. It prevents surface to hand transmission of viruses and bacteria for one year on high-touch surfaces, and four years on low-touch surfaces. This stands head and shoulders above other surface treatments offered in New Zealand, which require re-application every 30 days. These other products are also known to discolour certain surfaces.
