Preparation coatings
It is important to assess the condition of your factory painted metal or Colorbond roof prior to purchasing your preparation and finish products to make sure you get the most longevity out of the finish on your metal roof. If there are any rusted areas, then they need to be treated either by cleaning down with a wire brush and applying a coat of Rustshield W or Rustshield T or you may be best to replace that section of roof. Once the rusted areas have been addressed then you will need to apply a coat of Shieldseal W plus to the factory painted metal or Colorbond roof prior to applying you finish coats.

Finish coatings
Once you have applied your appropriate sealer then you are ready to apply your two finish coats of Roofbond Roofing Paint with the colour of your choice to your factory painted metal or Colorbond roof.

Important Information
Roof safety is often overlook by inexperience tradesmen or DIY. Be sure to wear a respirator when carrying out roof restoration work and it is advisable to have fall arrest equipment (safety harness/scaffolding).

Final word
You can re fit the down pipes 7 days after you have finished the job and will now be safe to collect drinking water.
