Steelseal Repaint System for Firmly Adhering Weathered Plastisol Standard Specification No. 5 PREPARATION Areas of mould or algae growth must be treated with a proprietary fungdicidal solution (used in accordance with the manufacturer's instructions). This must be done prior to washing down of surfaces and may require repeat application to effectively sterilise the surface. Thoroughly wash down with a suitable detergent solution so as to remove all dirt, chalk deposits, oil, grease, residues from sterilisation and any other deleterious matter. Fresh water rinse and allow to dry. Most common areas of corrosion occur at sheet ends/sides, overlaps and as a result of mechanical damage. Remove corrosion by mechanical abrasive tools to achieve bright metal substrate feathering back adjacent sound Plastisol. Any white zinc salts must also be removed by dry abrasing, using nylon scouring pads or similar. Remove any 'lift & curl' Plastisol at the bottom of the sheets where necessary, by mechanical means, and feather the edges back to a sound basis. Ensure all surfaces are clean, dry and free from oil, grease or other deleterious matter before painting commences. PAINTING Patch Primer To prepare bare steel and areas apply: Steelseal primer, PC4VQ series (brush), PC4VP series (A spray), DFT 50-60µms 1st Coat: Steelseal primer, PC4VQ Series (Brush), PC4VP Series (Airless Spray), DFT 50 - 60 µms. 2nd Coat: Steelseal Topcoat, PC5VF Series, DFT 50-60µms Dependent on the colour, method of application and profile detail an additional topcoat may be necessary to achieve maximum opacity. Consideration should be given to surface profile, accessibility, location, and equipment used. Work should be carried out using good painting practices and application techniques to ensure that a continuous, even wet film, is applied. Pigment orientation of metallic shades can result in sueding effects if applied incorrectly. The above suggestions are given in good faith, without prejudice or liability, and all materials should be applied in strict accordance with the product data sheets and Steelseal Repaint Systems - Notes for Guidance. This specification is valid for 6 months from the date of the document. Further deterioration in site conditions may occur after this time, which would require a new specification.
