Resene Popular Paint Systems –
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.

Is waterproofing an issue?
We often get requests for a clear finish on blockwork and concrete and while it is possible to apply Resene Multishield+ (now Resene Concrete Clear), Resene F-10 Glaze or Resene Uracryl clear directly to blockwork it may be problematic. This is because any moisture that gets trapped behind the clear film will make the film cloudy. This effect will disappear as the surface dries. Because none of these products are applied thickly enough and blockwork has so many holes and voids it is inevitable that this will occur.
The best solution is to ensure the pointing (the plaster between the blocks) is of a high standard, ideally with added water repellent, and then saturate the wall with Resene Aquapel.
Unpainted concrete blocks usually need waterproofing with Resene X-200. Resene recommend that three coats are applied to ensure that all the voids and holes in the blockwork are filled and therefore waterproofed.
On new blockwork it is not usually necessary to use Resene Concrete Primer, however if the surface is old, use Resene Sureseal, even if three coats of Resene X-200 are to be used. This is to prevent salt staining, reduce surface porosity and ensure the surface is sound.
Use two to three coats of Resene Sonyx 101 or Resene Lumbersider, however if either Resene Sureseal (old blockwork) or Resene Concrete Primer (new work) is used, only two coats of the topcoat will be generally needed. If using a red or yellow, a third coat of the topcoat may be required.
