Concrete, plasters and cement-based substrates: 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 substrate 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:
Is the substrate, including any existing paint in sound condition?

Is waterproofing an issue?
Some very old buildings may originally have been coated in a limewash or similar, very poorly bound paint. Typically they are very weak and friable and while waterblasting will remove the layers of paint, it may be a mammoth and unwanted undertaking.
The alternative is to thoroughly scrub and wash to remove the worst flaking areas, spot prime with Resene Sureseal and paint with Resene AquaShield, Resene X-200 or Resene Lumbersider.
If there is a black paint beneath the coating, this is most likely to be bitumen based and you should refer to the next flowchart.
