How to paint weatherboards

When your weatherboards are looking a little weathered it’s time to give them the Diamond treatment.

1. First you need to understand what paint quality you’re dealing with. 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.

Similarly, older homes may have a lead-based paint treatment, which is also more involved to remove. In any case, ask your Diamond® professional on how to remove these safely.

2. 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 you can use a paint scraper and sandpaper to remove flaking paint.

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

3.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.
