Aqueous Guard® PLUS+ and Aqueous Guard® PLUS+ Rapid Cure Antimicrobial Coatings

Looking for antibacterial and antimicrobial coatings? We provide two antimicrobial ceramic coatings – Aqueous Guard® PLUS+ and the faster-acting PLUS+ Rapid Cure. Incorporating Biomaster® silver ion technology, these coatings offer the same performance of the original Aqueous Guard® ceramic coating, but with the added benefit of reducing bacteria and virus levels on the surface. Please note that both of these products require training before use. Get in touch today to request a quote.

Built-in Trace Technology

Both of these coatings have built-in tracer technology, allowing detection of the coating on the surface to highlight the need for re-application as and when required. As the Biomaster® technology is effective for the lifetime of the coating being able to detect the coating on the surface allows us to determine the antimicrobial element of the coating is still present and therefore still fully effective wherever the coating is detected.

How It Works

Aqueous Guard® PLUS+ and PLUS+ Rapid Cure have three modes of action. When bacteria lands on an Aqueous Guard® PLUS+ protected surface, they are prevented from growing, producing energy or replicating therefore they die. The Biomaster® technology within the coating binds to the cell wall, disrupting growth. The Biomaster® then interferes with enzyme production, stopping the cell producing energy. Finally, Biomaster® interrupts the cell’s DNA preventing replication.


PLUS+ Rapid Cure has been developed to provide a faster curing time than our PLUS+ coating. PLUS+ Rapid Cure is ideal for areas that don’t have the luxury of being left to cure for a few hours. PLUS+ is more suited to larger panels or for hotter climates where the heat is likely to cause the coating to dry much faster.

Effective against Bacteria

In typical tests to ISO 22196:2011 standard, Biomaster® reduced levels of E.coli MRSA, Listeria, Legionella, Salmonella, Campylobacter and Staphylococcus aureus by more than 99%.


The coating has now been tested to ISO 21702:2019 against SARS-COV-2 (the cause of COVID-19) and shown to reduce SARS-COV-2 by more than 73.7% in just 2 hours compared to the control sample.
