'How to' Guide: Factory Colour Coated Steel Roof (Colorbond)

Preparation work
Remember when painting your factory painted metal or Colorbond roof, preparation is the key! The first thing you will have to do is remove all down pipes. Next, you will need to clean down your roof by applying Shieldcoat’s Mouldshield C diluted 5:1 with water, with a soft broom and then wash off with a pressure washer that preferably has a pressure of at least 3000 psi.

Remember when painting your factory painted metal or Colorbond roof, preparation is the key!

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.

Factory Colour Coated Steel Roof (Colorbond) F.A.Q.

Q: What kind of coverage will I get out of 15lts of Mouldshield C on a my roof?

A: It is difficult to give a coverage rate on 15lt of Moulshield c because it can be diluted between 5:1 up to 20:1 depending on strength needed and again how its applied; sprayed, watering can or broom. Generally one 15lt is enough for a 3 bedroom house roof, leaving you with enough left over to do your bit of cleaning around the home.
