Preparation of Substrates Ensure that all surfaces to be coated are clean and dry and free from all traces of oil and grease. Steel: New steel sheet: Treat new steel sheet with 971 metal Conditioner Do not allow the solution to dry, but wipe off with clean cloths. Rinse well with water to remove excess acid then wipe dry with clean cloths. Apply 404 Automotive Enamel Undercoat or 404 NS primer immediately after preparation of the clean surface. Aluminium: Bare aluminium surfaces should be thoroughly cleaned using R123 Wax and Grease remover before sanding, if necessary use a high grade scouring pad to remove heavy areas of grease and imperfections, all this is to be done in a wipe on wipe off motion using clean rags. Once dry, thoroughly abrade the surface using P240 grit on an orbital sander or by hand rubbing using P320. Once sanded the aluminium should be thoroughly blown down then cleaned with a 1:1 solution mix of R207 Methylated Spirits and clean water, using a wipe on wipe off action this must be repeated until no residue shows on the cleaning cloths. *NOTE: The prepared aluminium must be primed within 6 hours after the preparation process; failure to do this will allow the aluminium to re-oxidise. Apply 426 Vinyl Etch or 429 Paraphos Primer Surfacer or 406/413 Two pack Etch Primer. 2 2011 Protec Pty Ltd
