Painting floors and pavements in the food industry and health sectors with certified epoxy foodgrade paint for direct and indirect contact with food and beverages

Description of the problem

The application on floors and pavements of Fakolith food epoxy paints suitable for direct and indirect contact with food is increasingly in demand by industry, food certification bodies, health inspection, etc. It is clear that epoxy paints, even with their limitations and advantages over polyurethanes, tend to be the most common type of paint for finishing floors, floors and multilayer floors. Thanks to the high performance FoodGrade epoxy paints such as FK-100 FoodGrade (bio-hybrid 100% solids epoxy, EU and FDA certified), which has become the most widely used due to its extensive certifications, as well as its predecessors FK-45 FoodGrade (EU certified very high solids epoxy), also FK-45 FoodGrade Hygienic (EU certified very high solids epoxy-novolac) and FK-450 FoodGrade (EU certified high solids waterborne epoxy), you enjoy CE marking tests, and direct and indirect food contact certification with all food groups. Alternatively, you can also opt for the 2-component polyurethane FAKOPUR FoodGrade, especially for exterior applications. All Fakolith FoodGrade coatings are treated with BioFilmStop Green Antimicrobial Technology, which helps to inhibit the nesting of bacteria, biofilm and viruses that cause foodborne illnesses, thus increasing food and health safety.  If you are inexperinced with high solids epoxies, we recommend consulting our "Application guide, problems and solutions for high solids epoxy paints" before starting work with these paints.

Summary of the most common basic solution and procedure

The ideal pre-treatment to ensure maximum adhesion on a concrete pavement that is not new, is to perform adequate shot blasting and vacuuming to achieve a solid support, sanitized and with a proper planimetry and roughness (not polished), and above all free of dust and dirt in the pores, or with traces of old paints poorly adhered that prevent proper adhesion.

1. SURFACE CLEANING:   

· Option A - FAKOLITH FK-12: If the base has been shot-blasted or is already free of previous paint, the cleaner will be applied with subsequent rinsing with water, to eliminate leaving the pores of the pavement clean and free of dust, moisture damage, saltpetre, microorganisms, etc. After drying, the base is ready for the next treatment. 

· Option B - FAKOLITH FK-111: If on the other hand, there are layers of previous paints and it has been decided to repaint, we recommend to apply the descaler and cleaner of grease, pollution, industrial dirt, etc., with subsequent rinsing with water, to remove the dirt. Allow to dry completely before painting.

2. SURFACE PAINTING:   

Final painting between 2 to 4 coats with Fakolith FoodGrade food epoxy or polyurethane paint, whichever is more convenient in each case.  At least for the first coat and depending on the application, environmental and environmental conditions, we recommend diluting it up to 10% with its solvent, to provide better wetting, leveling and extend the pot-life. If a non-skid finish is required, FAKOLITH SLIP STOP should be added in the last 2 coats. See application details in its Technical Data Sheet.

· Option AFAKOLITH FK-100 FOODGRADE: There is no epoxy paint in its category with more food and physical-chemical resistance certifications, so it has become a multi-purpose standard that is also successfully applied on floors. In addition, as a partially bio-based epoxy paint, it is exempt from being considered dangerous goods for transport by road, sea or air, which makes it particularly easy to export. Alternatively (but without the option of shipping by air), the predecessor epoxy references FK-45 FoodGrade and FK-45 FoodGrade Hygienic are another option with similar characteristics.

· Option B - FAKOLITH FK-450 FOODGRADE: For surfaces up to medium stress, or with traces of moisture in the base, this water-based epoxy is highly recommended.

· Option C - FAKOPUR FOODGRADE: 2-component polyurethane paint, especially recommended in exterior situations or exposed to U.V. light.

Application process

1.- Option A - FK-12

PRODUCT SUMMARY: Concentrated water-based detergent cleaner, free of chlorine and formaldehyde, biodegradable and compatible with moisture. Wide range of applications and sectors, for use both indoors and outdoors, on horizontal and vertical surfaces.

To this end, FK-450 FoodGrade is being tested with simulants A, B, C, D2 (OM2-40ºC) and C (OM4-100ºC), as demonstrated by the tests carried out by Fakolith in independent certified entities, such as Tecnalia and the National Center for Food Technology (CNTA) among others, that it complies in all cases tested with the overall and specific migration limits imposed by these regulations for the above-mentioned simulants, which are equivalent to all simulants and therefore suitable for direct contact with all foods and beverages (exception: vinegar damages the resin): vinegar damages the epoxy resin. Not suitable for food intended for infants or young children according to regulation (EU) No 609/2013). FK-450 FoodGrade will have Food Conformity Declaration - Health Registration FAKOLITH RGSEAA ES-39.005259/T. Available in the main industrial colors of the food industry and sanitary sector.

AQUA-FOODGRADE TECHNOLOGY: FAKOLITH FK-450 FoodGrade is the first 2-component, high solids epoxy food paint that does not contain or require additional solvents or alcohols for its application. The A+B mixture incorporates water emulsion as a solvent. This is a milestone that will facilitate room temperature or forced drying, as water is much easier and safer to evaporate. Especially in confined spaces, having no flammable or volatile hazardous materials during application and curing is a great novelty and advantage.

BIOFILMSTOP SANITARY TECHNOLOGY (Treated article BPR Art.3 ): FK-450 Foodgrade is a food grade paint that combines FoodGrade Technology with BioFilmStop sanitary technology for inhibition and high resistance to biofilm and bacteria, ISO 22196:2011 (Escherichia coli, Listeria monocytogenes, Bacillus subtillis, Pseudonomas aureginosa, Staphylococcus aureus, Salmonella enteritidis, Legionella pnemophila, etc.). ...) also significantly improving HACCP, food safety and asepsis of the user industry. It also includes Fakolith's innovative FOODTECH film protection technology based on food preservatives.

MAIN USE: FK-450 FoodGrade food epoxy is specially formulated for the protection and finishing of mineral deposits of drinking water or water from food and agricultural processes, solid food deposits, as well as skirting boards, floors, walls, ceilings, objects, machinery, installations, structures, etc. located indoors. In general use in the food industry, health, pharmaceutical and cosmetic sector, industry in general, construction and civil works.

METHOD OF APPLICATION: After adequate preparation of the base and having checked the suitability of the environment, FK-450 FoodGrade can be applied by brush, roller or for optimal finishes and applications with AirMix or Airless spraying equipment. Slowly pour component B over component A, and stir at low revolutions with an electric agitator for at least 2 minutes until its correct homogenization. Let it rest for at least 1 minute before starting to apply. Always mix complete sets of A+B to avoid errors in the mixing ratio. Plan the application well taking into account its possible short pot-life. Can be applied in systems with fiber mesh in tanks and with anti-skid quartz sand in pavements. If necessary adjust the viscosity of the paint by adding 5-10% of potable water.

SERIAL COLORS: Off-white RAL 9010 and Grey RAL 7004. Consult availability, price and minimum quantity for other colors. 

ATTENTION TO APPLICATION AND CURE CONDITIONS: Drying times and waiting time for the second coat depend on the actual thickness of the layer, temperature, relative humidity and ventilation. The ambient and base temperature, as well as the temperature of the paint should never be lower than +10ºC nor higher than 35ºC, and the relative humidity should not be higher than 70-75%. The surface temperature of the base to be painted should always be at least 3ºC above the dew point to avoid condensation. It is estimated that the ideal application temperature is around 20ºC and 60% relative humidity. In case the environmental conditions are not adequate for its application and curing, these should be adapted with air extraction and ventilation, either at room temperature, with cold or heat, with dehumidifiers, etc; until the environmental conditions are adequate and stable during the application and curing, and always avoiding the generation of condensation humidity, since this would prevent the correct curing of the paint, a fact especially to be watched in tanks and confined spaces. The epoxy paint should not receive contact with water or surface condensation during the first 72 hours of curing, or the paint may not cure correctly, appearing "Amine Blush" wash spots.

OTHER GENERAL APPLICATIONS: The paint offers good general performance, at least after 72 hours of curing, although we recommend not to subject the paint film to severe chemical-physical aggressions until it has cured for at least 1 week (walls, floors, ceilings...indirect contact).
For further details see technical data sheet and/or application guides, and safety data sheet.
