The guide details of ALUMINIUM
 
   
Description:A relatively soft silvery metal which is damaged easily by acids and alkalis. Its striking feature is its low density(2.7) which makes it about three times lighter than other metals used in the building industry. A thin oxide film forms on the surface on exposure. Anodic oxidation is used to toughen the surface for many uses. Aluminium has a smooth and rather greasy surface.
   
Preparation:Abrade the bare metal with fine wet-or-dry abrasive paper using white spirit as a lubricant. Wipe off with clean cloths soaked in white spirit and then remove all residues with dry clean cloths. PRIMING Permoglaze Two-Pack Etch Primer FINISH Permoglaze Gloss Finish or Permoglaze Eggshell Finish. The following clear finish may also be applied over the cleaned metal for interior/exterior work -Permoglaze Anti-Tarnish laquer. For surfaces requiring high external and mechanical protection, use Permoglaze Polyurethane HQ Enamel.
