Without a doubt, sandwich panels, usually lacquered metal, or synthetic, are increasingly used in the food industry, health sectors and other industrial sectors, whether in cold rooms, clean rooms, production rooms, warehouses, technical rooms, etc. Although sandwich panels initially come factory lacquered, mainly in white, with their use they receive knocks, corrosion due to contact with humidity, wear and tear due to chemical aggression... deteriorating with the passage of time, so it is advisable to renew them properly. But how do we renew the paint or enamel of a sandwich panel? Fakolith has extensive experience in this regard. The first thing to do is to clean the panel properly and remove the rust, and then apply the appropriate anti-corrosion primer, either in general or at least on the corrosion points. Finally, the panel is finished with a food grade paint or enamel certified for direct and indirect contact with food and beverages. All Fakolith FoodGrade coatings are treated with BioFilmStop Green Food Antimicrobial Technology, which helps to inhibit the nesting of bacteria, biofilm and viruses that cause food borne illnesses, thus increasing food and health safety. This solution is generally applicable to other metal elements, such as beams, structures, etc...
IMPORTANT NOTE: If the surfaces to be painted have a significant risk of mould growth on indirect contact surfaces, then we recommend that you assess whether it is more appropriate to use our other range of Hygienic Coatings that are highly resistant to mould, bacteria, biofilm and other pathogenic microorganisms. If in doubt, please consult our technical team.
1. SURFACE CLEANING:
· CLEANOLITH Forte: Application 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 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 matt-satin finish, suitable for direct and indirect contact with foodstuffs, which is presented as the most versatile option for multiple surfaces. For surfaces requiring good hardness, medium physical-chemical stress, with easy renovation 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 - FAKOLITH FK-45 FOODGRADE HYGIENIC: Especially for such situations or on skirting boards and high performance surfaces, this high solids, high gloss food grade epoxy paint, with EU 10/2011 certification and CE marking tests, is often the most widely used choice for high performance surfaces, and also because it is an epoxy paint available in white. It takes more than 10°C to dry. Alternatively, you can also paint in white-cream and other colors with FK-100 FoodGrade (available in FoodGrade colorcard, except white), which is also FDA 21 CFR 175.300 certified,.

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.
