When your weatherboards are looking a little weathered it’s time to give them the Dulux treatment. Tested for over 40 years in Australian conditions, Dulux Weathershield is designed to withstand all weather, from extreme heat to heavy rain.


  1. First you need to understand what paint quality you’re dealing with on the surface. Using a sharp blade cut an X to your existing surface and cover with tape. If paint comes away when the tape is ripped off then it’s unsound and needs to be completely removed.
  2. Similarly, older homes may have a lead-based paint treatment, which is also more involved to remove. In any case, ask your Dulux professional on how to remove these safely.
  3. To clean your weatherboards, use a broom to remove cobwebs from beneath your eaves or around your gutters. If you don’t have a high-pressure hose remove flaking paint with a paint scraper and sandpaper.

    Cover and tape exterior lights with a plastic bag to prevent electrical damage when a hose is in use.

  4. Now you’re ready to start painting. For best results, begin at the top and work your way down. Paint the underside of your boards then the face. Use long strokes in horizontal motions from one side to the other.

    Never stop halfway along a board and return to it later or you’ll create an overlapping of paint, which is difficult to correct.

  5. And you’re done! Don’t forget to turn your leftover paint into hard waste with Dulux Envirosolutions Waste Paint Hardener.
