Contamination Control within Hospitals and Pharmaceutical Facilities using Antibacterial Coating


10Introduction – Antibacterial Coating within Hospitals and Pharmaceuticals

If you operate in an environment where the growth and spread of bacteria is an ongoing concern, Antibacterial Paints is the ideal solution. It is suitable for healthcare facilities including hospitals, aged care homes, medical clinics and laboratories.

Despite efforts to promote good hand hygiene practices, isolation protocols and cleaning of healthcare surfaces, Healthcare Associated Infections (HCAI) acquired during hospital stays are the most common complication of hospital care, and one of the most serious patient safety concerns.

Therefore, patient safety has become the prime focus of healthcare, and preventing HCAI remains a priority.
In many cases, healthcare facilities and associated laboratories consist of a constantly changing work environment and involvement with multiple physical, chemical, and/or biological agents. Also, due to the non-routine nature of the work conducted and the special characteristics of the work environment, there are potentially serious risks for exposure to contamination of various types, and significant challenges for personnel responsible for assuring the health and safety of the workers/ staff, patients, and visitors.

–    The use of such paints prevents the spread of infection while enabling the same high standard of cleaning and disinfection to take place in every room, ward, theatre, corridor and stairwell.
–    A number of studies have been carried out which shows that when walls covered in regular (non-antibacterial) paint are wiped, bacteria is left behind to breed. However, when cleaning walls that have been protected with such paints, the colonisation and growth of major pathogenic bacterial species are eliminated and 100% of bacteria are removed without damage to the surface.
–    Assessment of degree of bacterial colonisation of surfaces coated with Antibacterial paints have proven to be very effective against both Gram +Ve & gram –ve bacteria’s and this results in reduced chances of Nosocomial infections.
–    They prevent the colonisation and growth of major pathogenic bacterial species whilst enabling daily cleaning to take place without discoloration to walls ceilings or doors thereby saving the healthcare facilities of a large amount of money in repainting/re decoration costs every year.
–    These paints are invisible, odourless & does not affect the appearance or performance of any treated surfaces.
–    Surfaces coated with Anti Bacterial Powders/Paints deliver a constant and controlled release of silver ions and remain active for up to 10 years.

9Areas of Application

Painted or unpainted bricks, concrete, tiles, metals, stone, plaster, timber, walls, doors and ceilings, surfaces of beds, cubicle curtains, nurse call systems, wall and ceiling paints, floors and door handles, pull cords and case note holders, In patient rooms, reception areas, restrooms, corridors, high risk areas, kitchen, laundry and hand care, antibacterial coatings are required for the cleanliness of healthcare & pharmaceutical facility etc.

8The Benefits of Antibacterial Paints


–    Resists bacteria, germs, scuffing, blood, graffiti, uric acid, etc
–    Simply brush, roller or spray apply to protect any surface
–    Permanent non-stick finish makes cleaning easy
–    Dries to form a seamless and hygienic wipe clean barrier
–    Incredible long life, up to 20 years protection
–    Less redecoration means less disruption
–    Withstands 100s of cleaning operations
–    Highly abrasion resistant – absorbs damage and impacts
–    Quick drying – single coat application
–    Low odour and solvent free
–    Complies to all building regulations
–    Can be applied over corner guards, wall sheeting and bump rails
–    Withstands knocks and bangs from trolleys and equipment
–    Suitable for corridors, stairwells, wards, theatres, clean rooms, etc
–    Resists everything hospital life can throw at it
–    Independently tested
–    Protective
–    Long lasting

Areas/Walls protected with this infection control coating are much cleaner and the risk of HAI’s (Hospital acquired infection) is therefore greatly reduced.

Some of the latest interior emulsion paints have advanced anti-bacterial properties, They are proven to be effective against six disease causing bacteria such as MRSA, E.coli and Salmonella etc can cause health problems like blood poisoning, respiratory infections, and intestinal infections. Hence, they are ideal to be used in places such as hospitals & nursing homes.

6Facts of the Coating

–    The coating penetrates the membrane of the bacterium, dissipates the cell thus destroying the bacterium and preventing further growth
–    Different colours are available to match with the colour of the walls.
–    The Antibacterial coating remains active over 10 Years!

5Now the important question is – Can bacteria survive on walls?


–    Bacteria can come into contact with painted surfaces via a number of ways, for example, by the deposit of dusts and fine aerosols or by human skin contact and splashes of liquids.
–    Some bacteria can survive on dry surfaces for intervals ranging from a few hours to a few days, in rare cases months and, in the case of certain bacterial spores, even many years.
–    However, all require free water to grow. When contaminated water impacts on a surface it gradually dries out. Clearly, during this drying period there is a potential opportunity for any bacteria contained in the liquid to grow. This period will depend on the volume deposited, the ambient temperature and the humidity present.
–    Not only the walls, the entire hospital ceiling can be made dustproof. Furthermore, the post antibacterial coating of the panels increases the level of environmental health. The panels can be cleaned with warm water or non-abrasive detergent without altering the bactericidal effect.
In places where Joints are seen, an Antibacterial Sealant is advisable which is Waterproof & resistant to ageing. A Sealant has several different uses and can be used on various different surfaces, including, concrete, wood, metal, glass, hard PVC, tiles and plaster. It contains chemicals which are antibacterial protection used in conjunction with Hygiene Paints.

3A Sealant is


–    Permanently highly elastic (>900%).
–    Mould resistant, antibacterial.
–    Waterproof.
–    Very resistant to ageing.
–    Has very good adhesion on almost any substrate including paint and is easy to apply.
–    Suitable for sealing, jointing, filling, fixing, glueing on concrete, wood, metal, glass, hard PVC, tiles, plaster, alu-bitumen etc.
–    White walls can be easily sealed as it is available in white colour.

A wide range of hygienic and anti bacterial wall and ceiling paints are available in the market today. These products have all been specifically manufactured to ensure that certain environments, such as hospitals, are clean, hygienic and that the spread of germs is kept to a minimum. Anti-Bacterial Hygiene Wall and Ceiling Paint is excellent for use internally or externally in environments where a high level of hygiene is always of high importance

In low wear areas, a tough anti-bacterial acrylic resin based coating designed for application on wall and ceilings is recommended. Suitable for application to a wide range of substrates such as plaster, concrete, timber, cement render, previously painted surfaces. It kills many types of bacteria & in addition to this is also excellent weather resistant.


In short, the Antibacterial & Antimicrobial paints are more commonly used in areas more prone to infection such as operation theatres, intensive care units (ICU’s), surgical units, labour rooms, laboratories, blood sample collection areas, Infectious wards, Immunization areas, Blood banks, IVF departments where chances of hospital acquired infections are more. However, they can also be used in patient rooms, corridors & other areas where there is heavy traffic movement.
