Legislative Decree n. 193 of 06/11/2007
“Implementation of Directive 2004/41/EC relating to food safety controls and application of community regulations in the same sector” - HACCP
UNI 11021:2002 “Products and systems for painting environments with the presence of food”, in particular it is suitable for walls, ceilings and surfaces for which resistance to washing is required; can be washed with chloroactive detergent (detergent A); can be washed with alkaline degreaser (detergent B); can be washed with acid descaler (detergent C); can be washed with disinfectant (detergent D); resists temperature changes.

Concrete
The surfaces to be coated must be stable, clean and free of substances that can affect the adhesion of the coating such as dirt, grease, oil, traces of coatings and surface treatments, etc. Any weak or detaching parts must be removed before applying the product by mechanical sanding with diamond discs and dust extraction. The tensile strength must not be less than 1.5 N/mm².
The application of Protech WAC-RC on new or particularly absorbent cementitious substrates must always be preceded by the application of a coat of Protech fix AC water-based anchoring primer. Wait 3-4 hours before applying the finish.

Resin coatings
The surfaces to be coated must be stable, clean and free of substances that can affect the adhesion of the coating such as dirt, grease, oil, etc. Sand the surface by mechanical sanding with diamond discs and dust extraction. It is advisable to wash the surfaces and wait for them to dry completely before applying the finish.
The application of Protech WAC-RC on resinous and multilayer systems must always be preceded by sanding the entire surface in order to promote and guarantee optimal adhesion of the product to the support.

PVC
Wash the PVC surfaces to be treated with specific detergents to remove any substances that may affect the adhesion of the coating such as dirt, grease, oil, materials that block the pores in order to promote better capillary penetration of the product into the support.
The application of Protech WAC-RC on PVC supports can be carried out directly with appropriate dilutions of the product in first and second coat.

Steel
Any welding residues must be removed and the joints sanded. Sandblast to cleanliness level Sa 2½ according to ISO8501-1. The surfaces to be coated must be free from dirt, oil, grease and impurities. Average surface roughness degree RZ ≥ 50 μm. An anti-corrosion treatment is recommended before applying the coating.
The application of Protech WAC-RC on steel supports must always be preceded by the application of a coat of “surface tolerant” epoxy-polyamide primer in the solvent phase Syntech Poliurea Primer Epoxy Metal.

Thoroughly homogenize the product by manually shaking the container before use or mechanically, taking care to use a clean tool free of potentially polluting substances. The support must have a temperature at least +3°C higher than the dew point to reduce the risk of condensation or bleaching of the finish.

Application
The product can be applied evenly by spray, roller or brush to avoid accumulations of material which could give rise to aesthetic defects. The application of the product must be carried out by crossing the passes and paying particular attention to the shots, regularly unloading the roller beyond the applied area in order to obtain a uniform film and eliminate any accumulations of product. Apply the first coat of Protech WAC-RC diluted with 20% max by weight of clean water and taking care to respect the indicated consumption and thickness. The dilution must be carried out under mechanical stirring by adding the necessary quantity of water after having homogenized the product in the container. Wait at least 3-4 hours, then apply the second coat of colored finish diluted with 10-15% max by weight of clean water.

PVC
Apply the first coat of Protech WAC-RC diluted with 5-10% max by weight of clean water and taking care to respect the indicated consumption and thickness. The dilution must be carried out under mechanical stirring by adding the necessary quantity of water after having homogenized the product in the container. Wait at least 3-4 hours, then apply the second coat of colored finish as is.
