Cheese processing with Hygienic coatings NZ

Hygiene coatings NZ: Food & beverage industry-approved coatings

Thousands of companies produce, process, transport and import food and drinkable products in the New Zealand. The industry itself remains the country’s linchpin – worth approximately $25 billion.  Every company dealing with this is legally obliged to comply with a food safety programme. The law approves the application of HACCP (Hazard Analysis and Critical Control Points) standards in order to be exempt from the Food Hygiene Regulations. Food & beverage hygiene coatings NZ are especially designed for applications where hygiene is of key importance; they keep surfaces free from bacteria, preventing contamination and contributing to food safety. Generally, requirements for hygiene coatings include:

  • Repels contaminants during and between different activities
  • Easy to clean and chemical resistant
  • Low air pollution and prevents fungi and mould formation
  • Hard, impermeable and non-absorbent
  • Easy to maintain and durable

Choosing hygiene coatings NZ

Choosing the best hygiene coating

When you are looking for a hygienic paint, you will want it to be antibacterial or antimicrobial, and to conform to food safety regulations. When choosing a hygienic paint, ensure that it has:

  1. HACCP certification to make sure requirements are met
  2. Antimicrobial additives such as silver to inhibit bacterial and fungal growth
  3. Whether they conform with the relevant Standards and meet Health and Safety requirements

In areas where the surfaces must remain hygienic at all times, such as kitchens and food factories, silver ion-containing coatings are nearly a must. Even these bactericidal coatings require frequent cleaning to maintain a hygienic environment.

HACCP coating: a globally recognised benchmark

HACCP for Hygienic coating NZ

HACCP is a globally recognised food safety standard

The system, HACCP, is a globally recognized food safety standard with the main goal of minimizing food-borne illnesses. The system offers guidelines for work processes in the food industry to prevent contamination.The ISO 22000 functions as a standard in the field of food safety that was developed by the International Organization for Standardization. The ISO 2200 sets strict requirements for organizations in the dairy and food industry. This ISO standard was developed to put a safety standard on the market that can be accepted worldwide.

In New Zealand, food operators must meet requirements of the Food Act 2014 by either operating under the Food Hygiene Regulations 1974 Local Authority or Council registration or applying for an exemption from the Food Hygiene Regulations and operating a Ministry of Primary Industries (MPI) approved food safety programme.

An HACCP coating is therefore certified to meet both the Australian and New Zealand standards. Additionally, goods produced in facilities with HACCP certification are more easily exported than those without, especially to other HACCP-recognising countries like the United States.


What is the most suitable hygienic coating for my scenario ?

An absolutely hygienic environment cannot be achieved unless the floor contributes to preventing bacterial growth and spread. Therefore, hygiene coatings for floors are of key importance in many food processing facilities. The right type of hygienic coating for floors is dependent on what is expected from the floor itself. Therefore, we have drawn up 5 scenarios where you may need hygienic coatings for floors, to help you identify the most suitable hygienic coating for your project.

1.Operations require minimum to no downtime

Coating to apply: MMA (methyl methacrylate) coatings, polyurea floor coatings

A factory where continuous food processing takes place can often not be shut down for a long period. To prevent long-term downtime, you need a coating that can be quickly applied and cured. This allows you to use the location almost immediately after application. In that case, MMA coatings or polyureas are suitable – the curing time of which is between 30 seconds and 2 minutes. These coatings are suitable for floors with medium loads and are easy to clean and maintain.

2. Food is present during the application of HACCP coating

Suitable coatings: 100% solid epoxy or polyurethane, water-based flooring systems

Sometimes a hygienic floor coating is urgently needed and the presence of foodstuffs during application can not be avoided. Then you should look for HACCP floor coatings with a minimum VOC content (volatile organic compounds), such as a 100% solids coating. These epoxy coatings can also be applied in a thick layer, which means fewer additional layers are needed. Another option is a water-based floor coating that is quicker to apply than epoxy, but in comparison probably less durable.

3. The concrete floor is in a bad condition but requires a hygenic coating with minimal pre-treatment

Suitable coatings: self leveling floor systems

You open a new company, but the floor is in a very poor condition, or your floor needs a new layer of hygienic paint, but the current layer is damaged. To minimize downtime and avoid high surface preparation costs, choose a self-leveling floor coating; it is easy to apply, fills holes and cracks and requires less pre-treatment.

4. Applying a decorative coating to a light or mid load area

Suitable coatings: polyurethane coatings

A polyurethane floor coating is the best choice if you want a decorative concrete finish. This floor coating is available in a wide range of colors. Besides an attractive finish, the coating is flexible, easy to clean and comfortable to walk on, ideal; for example, in pedestrian areas and restaurant floors.

5. Hygienic coatings in companies with heavy chemical and mechanical loads

Suitable coatings: Epoxy resin floor coatings

In heavy food processing plants, such as dairy production plants, slaughterhouses and distilleries, the floor must be absolutely resistant to wear by vehicles and pedestrians as well as heavy mechanical and chemical stress. In those cases the best option is a hygienic epoxy floor coating. Epoxy is a highly resistant coating to these.


Achieve higher standards with hygienic wall coatings

Walls of food processing and preparing areas are subject to similar regulations as floors. They must be:

  • Appropriate for the area and protect food from contamination.
  • Easy to clean and they must inhibit pests
  • Sealed to further prevent dust, dirt and pests in the area; the sealing is often done by coatings that rely on nanotechnology.

Additionally, there are three types of resin coatings that, when they contain the appropriate antimicrobial additives, can be applied as hygienic wall coatings:

  1. Epoxy: This the most durable of the hygienic wall coatings. It is extremely chemical resistant and endures abrasion; you can even use a pressure washer to clean it.
  2. Polyurethane: As on the floor, so on the walls. These hygiene coatings are decorative, easy to clean, and able to resist chemicals and medium abrasion.
  3. Acrylic: These hygienic wall coatings are easy and fast to apply, yet they may not provide the best abrasion and chemical resistance. Therefore they should be used on areas that have a lower risk for contamination.

Find hygienic coating companies in New Zealand

To achieve the best finish, the application of a hygiene coating must be carried out by a professional and certified contractor. The application can not only be complex, but the surface must also meet the standards; only a certified contractor can provide you with the correct documentation showing that the coating meets the required standards. To make your search a bit easier, we have compiled a list of specialists in the New Zealand. If you want more information, do not hesitate to contact us. We at Coating.co.nz are happy to help you!
