Roofing products and roof paint preparations: training notes
This web page is an edited version of the Resene Best System Selling training notes provided to Resene staff and is provided to enable you to gain a greater understanding of the substrates and paint systems you may encounter in your decorating project. It is impossible to cover all decorating scenarios in a single document, so if you are in doubt about any aspect of your project please contact Resene for assistance.
Select the roof product type you will be painting from the list below to view how to prepare and finish the surface.
Note: Refer to the PDF flowchart for a visual of the steps below:
Wash down using Resene Roof Wash and Paint Cleaner to remove surface chalking and any surface contaminants
Remove ‘white rust’ if present and spot prime with Resene Galvo One
1 To optimise the benefits of the Resene Cool Colour topcoat use Resene Cool Primer
Older COLORSTEEL® and COLORBOND® roofs will be faded and chalked and in severe cases, white rust and corrosion will be evident. Use Resene Roof Wash and Paint Cleaner to prepare the surface, scrubbing any white rust with a nylon Scotchbrite scouring pad. Prime the affected areas with Resene Galvo One.
COLORBOND® is the Australian equivalent to COLORSTEEL®.
Crown Roof Paint along with most other products on the market is not able to be applied directly to COLORSTEEL®. Resene Hi-Glo will also stick to new COLORSTEEL®/COLORBOND®, provided it has had a couple of weeks’ weathering.
COLORSTEEL® and COLORBOND® profiles are usually either corrugated or Biga Rib.
See appendix for more information on painted COLORSTEEL®.
Refer to Resene if there is delamination present (as there is in the photo) as this could represent a COLORSTEEL® system failure.
