Resene Popular Paint Systems – exterior timber: 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 timber surface you will be painting from the list below to view how to prepare and finish the surface.
Preparation & finishing flowcharts
Note: Refer to the PDF flowchart for a visual of the steps below:
Thoroughly wash - ideally with Resene Paint Prep and Housewash, rinse well
Fill any nail holes and cracks with Contract Filler, sand smooth and spot prime
Most new windows come pre-primed and are coated in the same pre-primers as weatherboards. Unfortunately the same quality issues also arise – refer to the section on new weatherboards.
If windows are puttied (as opposed to using a timber bead) wait until it is firm to touch before proceeding to the painting stage – usually after 10 days, unless a synthetic fast drying putty has been used.
It is important to paint the top, bottom and inside edges of the window to ensure a good moisture seal and help reduce swelling. We strongly recommend the full three coat system is applied to these areas.
Traditional full gloss solventborne enamels used to be our only recommendation for exterior joinery however because of the significant increase in U.V. resistance that the waterborne enamels have and their ease of application they are now preferred.
A full gloss solventborne enamel can still be used – refer later flowchart, however the waterborne equivalent would be expected to perform better.
While the basis of some debate we recommend that windows are completed before the weatherboards and that the edges or scribers are (see photo) painted the same colour as the window frames rather than the weatherboard colour if different.
