How to Prepare Weatherboards for Painting

There are a few things you must check before painting your weatherboards:

  • Are any repairs needed? Check for rotten weatherboards, doors and windows.
  • Are the gutters sound? Check for any leaks.
  • Are there any rusted nail heads? If so, sand them and then use metal primer
  • Have you got bleeding knots in the weatherboards? If so, prime them.
  • Do you have nails that need resetting? If so, use a nail punch to align them, sand, prime and fill them.
  • Scrape off peeling paint with a scraper before sanding to a flat finish.

Another thing you must do when you learn how to prepare old weatherboards for painting is to take time to sand back weatherboards. This ensures better adhesion of the exterior paint to the weatherboard surface.

Due to the possible presence of lead, if your weatherboard house hasn’t been painted in over 30 years, we advise you do several random adhesion tests that can detect lead paint.Your local Haymes Paint stockist will be able to give you further advice on this. Otherwise, follow these instructions for painting weatherboards:

Step One: Clean the weatherboards: Use a broom to remove any cobwebs around the gutters or under the eaves.

Step Two: Rinse the weatherboards thoroughly with clean water and allow them to dry. If possible, use a high-pressure water hose.

Step Three: If there are any stubborn surface stains on the weatherboards, wearing rubber gloves, wash down the weatherboard surfaces with sugar soap. Apply the sugar soap and leave to dry for 5 minutes before rinsing thoroughly.

Step Four: Remove any flaking or loose paint with sandpaper and a scraper.

Step Five: Fill any gaps with exterior filler, allowing it to dry before sanding back. It’s important to check the ends of the weatherboards and use gap filler if holes are present.

Step Six: Use Haymes Paint Ultra Premium Solashield Exterior to spot prime any areas. This water-based colorant is UV resistant formula and is simple to apply.
