Good painting decisions begin before the first bucket is opened. Use this guide as a practical starting point, then confirm the details of your own building before purchasing or beginning work.
Check for moisture first
Painting over a damp wall can lead to blistering, staining and peeling. Identify roof leaks, plumbing leaks, rising damp or exterior water entry before decoration.
Remove weak material
Flaking paint, loose plaster, powdery surfaces and dirt should not be sealed under a new finish. Scrape, clean and repair until the substrate is sound.
Repair cracks correctly
Hairline cracks and structural movement are different problems. The repair method should match the cause and size of the defect.
Prime where the system requires it
New plaster, repaired areas, stains, metal and some previously painted surfaces may need a suitable primer or sealer before finishing coats.
