In all cases, finish with 35 - 70 microns of 841 Outdoor Polyurethane. In high or very high agressive environments (C4 or C5 according to ISO INE EN ISO 12944), one or two coats of 832 Epoxy Primer will be required before finishing with 841 Outdoor Polyurethane .

MAINTENANCE OF PREVIOUSLY COATED SURFACES IN GOOD CONDITION:
If overcoating on well adhered systems, remove grease, oils and dirt (by freshwater jet, solvent etc.) Afterwards let to thoroughly dry and apply one or two coats of 841 Outdoor Polyurethane, depending on requirements.

MAINTENANCE OF PREVIOUSLY COATED SURFACES IN POOR CONDITION:
For poorly adhered systems and/or showing rust, remove them by sandblasting up to Sa 2 ½ grade of the ISO 8501-2 standard or by means of manual or mechanical cleaning, up to ST3 grade of this same standard. Patch with a suitable primer, preferably by brush and apply the required number of coats of 841 Outdoor Polyurethane Enamel.
