IMPORTANCE OF HYGIENE COATINGS
There are many different types of micro-organisms that co-exist with humans in shared environments with the vast majority harmless, causing no potential threat to humans. However, there are still many micro-organisms that can have a negative impact, causing infection and sometimes disease. Infectious disease caused by the growth and colonisation of micro-organisms contribute to millions of deaths in the world each year and in order to protect against the threat of these organisms it is imperative to take effective hygiene measures so as to eradicate or reduce any unnecessary risk.
Conventional fungistatic paints release a fungicide by leaching and typically become defenceless against mould and bacteria within a relatively short time. Our special multiple active ingredients are incorporated into the polymer matrix of our hygiene coatings to actively combat the growth of micro-organisms. Our coatings remain active against micro-organisms throughout their long design life. The anti-microbial system does not leach out and washing the surface does not diminish the coating’s ability to prevent microbial growth.
All our hygiene coatings have water-based formulations, in line with the global trend towards environmentally safe products. Consequently they cure without releasing any strong odour, actively combat the growth of micro-organisms and present no fire risks either during application or whilst curing. In addition, they are Mesatile Oxide free and contain no phenols, mercurials or heavy complexes and will not leach out any biocides or other toxic chemicals.
Unlike many traditional materials, our hygiene coatings don’t need to be replaced at the end of their lives; when maintenance is eventually required, a simple re-coat is all that is needed to restore the original performance and life span. Our coatings are designed to offer exceptional durability in the most demanding of environments, with typical life spans in excess of 10 years.
IMPORTANCE OF WALL COATINGS
Dekro Hygiene wall coatings are water-based and have no flash point. They may therefore be used without the release of strong odour or harmful solvents, and present no fire risk during application. As a result, although the coatings are designed primarily to perform in aggressive external applications, they may also be used for highly demanding internal projects.
Many standard colours are available and special colour batches may also be produced to meet particular design requirements or to match the appearance of an existing substrate. In addition, the range also includes a clear weatherproof coating with a highly advanced impregnation system which protects porous materials such as brickwork and stone without significantly altering their appearance.
All Dekro Paints products are manufactured in accordance with the demands of British Standard, European Norms and ISO 9001, the international standard for quality assurance.
In order to assist building owners, designers and specifiers in the selection of the most appropriate system for any given project, Dekro Paints offers free technical and onsite support and the production for detailed written method statements. It is also able to provide a list of contractors who are skilled in the use of the company’s products. These services may be arranged through Dekro Paints.
The following sections provide detailed information about the standard range of Dekro Paints wall treatments.

LIST OF BACTERIAL INFECTIONS THAT DEKRO HYGIENE SOLUTIONS OFFER PROTECTION AGAINST
More commonly known as E.Coli, this has been identified as one of the biggest threats to food safety, as the level of bacterial contamination needed to produce food poisoning is very low, fewer than 10 individual bacteria can potentially lead to serious illness. The bacteria are found in undercooked meat products such as beef burgers, as well as other products including milk, yoghurt, raw vegetables and water. It can be spread from person to person if personal hygiene is inadequate.
Methicillin Resistant Stryphylococcus Aureus
MRSA is a form of bacteria which has caused massive problems in hospitals, doctors surgeries and clinics. It causes wound infections in people who have had recent surgery or injury and can cause chronic health problems, amputations or even death. It is one of the most dangerous forms of bacteria, because normal antibiotics do not kill it. An infected patient treated in hospital is usually kept in isolation and once the patient leaves it is imperative that the room be comprehensively cleaned to eradicate the presence of MRSA.
Salmonella is the second most common cause of food poisoning. Contaminated meat products such as burgers, sausages and chicken, are the main causes of infection and a relatively high mortality rate is common with this organism, especially in the elderly, demonstrating the need for safe handling of food and strict hygiene regimes.
A type of yeast like fungi present in all human beings; problems can occur when the amount of this yeast becomes abnormal. Symptoms of the Candida infection include thrush, athlete’s foot and migraines. Even though Candida species are normally confinedto the human body there are frequently cases where it has been discovered in hospitals, on food, counter tops and floors. It is imperative that all of these areas are impeccably clean at all times.

FREQUENTLY ASKED QUESTIONS
How do you determine the moisture level of a wall or other surface before painting?
It is very important to ensure that the moisture levels of walls or wood surfaces are suitable for paint. Damp is often the cause of discoloured plaster, loose wallpaper, peeling paint and ‘tell tale’ damp patches. Some damp can be noticed by mould growth or a musty odour. Often damp cannot be seen which, left unchecked, will cause problems. The most accurate way to determine moisture levels is with a damp detector. It will assess acceptable moisture levels and indicate excessive moisture requiring remedial action. Damp testing should be done methodically. Start outside, determining strategic places for damp. Examine the inside for potential problem areas. Important areas to test: floors and joints, door and window frames, skirting boards, walls, chimney breasts, inside cupboards and under the stairs, ceilings, especially under flat roofs, bathrooms, loft space. The detector can locate the source of moisture by taking different readings on the same wall. We can assist you with damp testing.
Can you explain why the colour in the paint can is not the same when it dries out on the walls?
The explanation begins with the fact that the components of paint reflect light differently when they are wet (in-can) compared to when they are dried (on the wall). These subtle differences are quite common and not a reflection on the quality of a paint product. A handy tip to make sure you are happy with the end colour on your wall is to use a sampler pot, apply the paint and check how it looks after drying.
Can I use a water-based paint over areas previously painted with solvent-based paint?
In short, yes you can. However some preparation is required before you start. First the surface needs to be sanded to a dull finish with a fine grit sandpaper, then wiped off with a damp cloth. A top quality pure acrylic water-based paint can then be applied quite successfully.
How should I paint on fresh plaster?
Fresh plaster should be allowed to dry thoroughly over a period of weeks depending on how thick the layer of plaster is and the ventilation in the room. Usually the plaster changes to a pale colour when drying and feels powdery smooth to touch. Once dry apply a quality primer followed by 1-2 layers of a high quality topcoat.
When and why is using a primer important?
Priming is essential when the surface is porous in any way, the surface has never been painted before or when the surface contains substances which can bleed through (eg. dirt, water and tobacco stains, tannins in wood such as mahogany). Priming has an important role; it blocks out staining materials from the surface being painted, it provides a good base for a uniform topcoat appearance and ensures maximum adhesion to the surface being painted. Primers can be solvent-based or water-based.
What if I just paint over the spores on my wood siding?
That will probably seal them in. It may solve your problem, but will give a pebbly appearance to your paint job. Each repainting will seal in the artillery fungus even more and your fungus problem will re-appear all the time.
Are there any registered fungicides that will kill the fungus? How about a weak solution of household bleach?
Mold and mildew can be a problem in areas that have high humidity and poor ventilation such as bathrooms kitchens, wine cellars, etc. bleach, would be very temporary, as it leaches out. Thales Wine Cellar Services have tested and approved our Hydrowash Fungicidal as safe for use and pose no risk of organohalogen contamination.
I have a mould problem in my bathroom. What is the easiest way to get rid of it and what should do to prevent it coming back?
The easiest way to get rid of mould is by washing the surface with Hydrowash Fungicidal. It will kill all the mould almost instantly. Preventing it from coming back depends on what type of paint you have on the walls and ceiling at the moment. We would recommend you use Dekro Hygiene Coatings.
How long should I wait before applying another coat of paint?
Although the paint will dry to touch fairly quickly, we recommend waiting four hours between coats. High humidity, low temperature, poor ventilation and thicker films will increase the recommended dry time.
