How Do I Paint Exterior Aluminium?

Aluminium is tricky to paint but if correct preparation is undertaken a solid and durable paint film can be achieved.

  • Wash down with Tikkurila roof cleaning agent, ensure all areas of white rust (oxidation) are removed, along with grease and contamination. To remove white oxidation a fine grade non-metallic sandpaper can be used. 
  • All surfaces must be dry. The temperature of the ambient air, surface or paint should not fall below + 5 ºC during application or drying. The surface temperature should remain at least 3°C above the dew point
  • If previously painted, remove any loose and flaking coatings and feather off any edges.


To prime, use 1 coat of either Rostex Super Akva Primer, Otex Akva, Otex Adhesion Primer or Temprime EE

To topcoat, use 2 coats of either Unica Akva, Unica Semi Gloss Enamel, Panssari Akva or Panssarimaali
