pintura sanitaria

Painting or renewal of sandwich panel, metals, lacquered metals and similar with certified foodgrade paint or enamel for direct and indirect contact, in the food industry and health sectors.

Description of the problem

Undoubtedly the sandwich panel, usually lacquered metals, are increasingly used in the food industry, health sectors and other industrial sectors, either in cold rooms, clean rooms, production rooms, warehouses, technical rooms, etc.. Although initially the sandwich panels are factory lacquered, mainly in white, with its use receives blows, corrosion by contact with moisture, wear by chemical aggression ... deteriorating with the passage of time, so it should be adequately renewed. But how do we renew the paint or enamel of a sandwich panel? Fakolith has great experience in this regard. The first thing is the proper cleaning of the panel and the removal of rust, then apply the appropriate anticorrosive primer, either in general, or at least in the corrosion points. Finally, the final finish should be applied with the most suitable food grade paint or enamel certified for direct and indirect contact with food and beverages. All Fakolith FoodGrade coatings are treated with BioFilmStop Green antimicrobial food technology, which helps to inhibit the nesting of bacteria, biofilm and viruses that cause foodborne illnesses, thus increasing food and health safety. This solution is generally applicable to other metal elements, such as beams, structures, etc...

Summary of the most common basic solution and procedure

1. SURFACE CLEANING:   

· FAKOLITH FK-111Application of the descaler and cleaner of grease, pollution, industrial dirt and biofilm matrix, and subsequent rinsing with water to remove the dirt. After drying, the base is ready for the next treatment. Alternatively, or if necessary, you can also use BIOFILMSTOP Cleaner fungicide, bactericide and virucide disinfectant with HA Sanitary Registration, for the disinfection and removal of biofilm, bacteria, fungi and viruses.

· FAKOLITH FK-9 GEL: Surface sanding of the overall surface to create texture, insisting on corrosion areas. Application of the oxide cleaner on the corrosion points of the panel. Once the oxidation has been eliminated, clean these surfaces with a cloth with foodgrade solvent FK-45 OEM Solvent or equivalent.    

2. SURFACE PRIMER:   

· FAKOLITH FK-44 POX: Application of the anticorrosive epoxy primer, either on the entire panel or only on the corrosion points, as appropriate, and finally allow to dry properly before proceeding with the final finish.

3. SURFACE PAINTING:

Final painting with 2-3 coats of FoodGrade food paint or enamel most suitable for the case:

· Option A - DISPAINT FOODGRADE: Innovative water-based enamel, fast drying, thin film and matte-satin finish, suitable for direct and indirect contact with food, which is presented as the most versatile option in multiple surfaces, wood, primed metal, already enameled surfaces, 3D printing parts, etc..  For surfaces requiring good hardness, medium physical-chemical stress, with easy renewal and maintenance. It has double certification EU 10/2011 and FDA 21 CFR 175.300, and CE marking tests, which broadens its field of use.

· Option B - DISPERLITH FOODGRADE ELASTIC: FoodGrade water-based paint, with good elasticity, fast drying, and satin finish, suitable for direct and indirect contact with food, for multiple surfaces that require a balance of elasticity, medium physical-chemical stress, and easy renovation and maintenance. It is EU 10/2011 certified and CE marking Tests. 

· Option C - FAKOLITH FK-45 FOODGRADE: Especially for this type of situations or in baseboards and high performance surfaces, this high solid and high gloss foodgrade epoxy paint, with EU 10/2011 certification and CE marking tests, is usually the most used option. It needs more than 10ºC to dry. Alternatively, you can also paint with FK-45 FoodGrade Hygienic, which has higher physical-chemical resistance, or FK-100 FoodGrade (except white color) if you additionally require FDA 21 CFR 175.300 certification.

Application process

1.- FK-111

DESCRIPTION AND MAIN USE: FAKOLITH FK-111 is a detergent cleaner for use with grease-based dirt or grime, pollution, biofilms matrix, scorching or industrial grime in general, on surfaces resistant to alkaline solutions. Mainly for use in the food industry, industry in general, construction and civil engineering. Health Register FAKOLITH RGSEAA ES-39.005259/T y ROESP E-0043-E.

RECOMMENDED THINNER: 1 part FK-111 to 4 parts water. Can also be used undiluted if necessary, in more contaminated areas or when speed of action is required.

HOW TO APPLY: Carefully protect all surfaces that are not to be treated from splashing. Apply diluted FK-111 using spray guns, brushes or rollers and immediately activate the product by scrubbing with a brush with stiff plastic bristles, working particularly on the worst affected areas. Allow 15-20 minutes to pass, although always before it has dried, and then wash off and rinse thoroughly using water under pressure. If so required the operation can be repeated. Leave to dry before going ahead with possible additional treatments. For further details consult the specifications sheet and/or application guidelines, along with the safety sheet.

AVERAGE YIELD: Undiluted FK-111 provides a yield of approx. 8-12 litres/m², although depending on the extent of the contamination this may vary considerably.

2.- FK-9 Gel

DESCRIPTION AND MAIN USE: FAKOLITH FK-9 Gel is a cleaner for the removal of rust from metals and lime-descaler, for use on surfaces resistant to acidic solutions. The gel format makes for easy application, avoids dripping and optimises consumption. Mainly for use in the food industry, industry in general, construction and civil engineering. Health Register FAKOLITH: RGSEAA ES-39.005259/T y ROESP E-0043-E.

HOW TO APPLY: Carefully protect all surfaces that are not to be treated from splashing. Generally speaking FK-9 Gel is applied abundantly, using synthetic brushes, to the rusty area of the metal and left to soak in until the rust is seen to have been removed. The product can be scrubbed in using a brush with stiff plastic bristles, working particularly on the worst affected areas. The layer of gel, along with the remains of the rust or limescale, must be cleaned off before it can dry, and the surface washed down and thoroughly rinsed using pressurised water. If so required the operation can be repeated. After rinsing with water we recommend that you dry the metallic surfaces using a solvent impregnated rag, and then either prime it or duly protect it as soon as possible, given that if you do not do so the rust will rapidly reappear. If you want to eliminate limescale make sure that the base is resistant to acidic solutions and proceed as indicated above, although in this case the process will be much faster. For further details consult the specifications sheet and/or application guidelines, along with the safety sheet.

AVERAGE YIELD: FK-9 Gel provides a variable yield although, depending on the extent of the corrosion to be eliminated, this may vary considerably.
