pintura sanitaria

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

Description of the problem

Undoubtedly the sandwich panel (lacquered metal), as well as other types of similar panels, are more and more used in the food industry, cold and clean rooms and other industrial sectors. Although initially sandwich panels comes white lacquered from factory, due to the use, shocks, contact with moisture and chemical attack, panels are damaged and should be adequately renewed. But, how we renew the paint of a sandwich panel in food industry? Fakolith has great experience in this regard. Firstly, do an adequate panel cleaning and oxide removal. Then, apply the suitable anticorrosive primer, either generally or at least at the points of corrosion. Finally, proceed to the final finish with the most convenient foodgrade paint certified for direct and indirect contact with food and beverages. All our paints incorporate the BioFilmStop antibacterial technology for greater food safety and hygiene. This solution is generally applicable to other metal elements such as beams, pipes, structures, etc.

Summary of the most common basic solution and procedure

1. SURFACE CLEANING:   

· FAKOLITH FK-111Application of the descaler and grease cleaner, pollution, industrial dirt and biofilm matrix, and subsequent rinsing with water, to remove dirt. After drying, leave the base ready for the next treatment. Alternatively, or if necessary, can be used the BIOFILMSTOP Cleaner with HA Health Record for the elimination of biofilm, bacteria, fungi, virus or also the multifunctional industrial cleaner FK-111 for greasy dirt.

· FAKOLITH FK-9 GEL: Application of the oxide cleaner on the corrosion points of the panel, remove with water and/or dry the surface with a cloth impregnated with solvent, such as FK-45 OEMSolvent.    

2. SURFACE PRIMER:   

· FAKOLITH FK-44 POX: Application of the anticorrosive epoxy primer on the entire panel or on the corrosion points, according to what is most convenient, and let it cure. The objective is to protect the panels against rust or critical points detected. Drying even at low temperature.    

3. SURFACE PAINTING:

Final painting with 2 coats of FoodGrade paint, suitable for use in the food industry in direct and indirect contact with food and in health sectors, with high resistance to moisture, friction, cleaning and disinfection, and with green BioFilmStop technology to inhibit biofilm and bacteria growth:    

· Option A - DISPERLITH FOODGRADE ELASTICThe first water-based and monocomponent foodgrade paint. It is the most recommended for painting or repainting mainly of surfaces of walls and ceilings, cement mortars and concrete, painted or to repaint in general. It also has CE marking tests, excellent impermeability and resistance to cleaning and disinfection. Drying even at low temperature.

· Option B - FAKOLITH FK-45 FOODGRADE: Especially over high-performance surfaces, the use of the high-solids epoxy foodgrade paint, with CE marking tests, is usually the most used option. It is needed a temperature higher than 10ºC for its drying. Alternatively, it can be also painted with FK-45 FoodGrade Hygienic which has higher physical-chemical resistance. 

Application process

1.- Option A - 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.

1.- Option B - 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.
