Key points & steps

  1. Empty or pull furniture into the centre of the room and lay heavy-duty canvas dust sheets.
  2. Wash walls with sugar soap, fill any nail holes or hairline cracks, and lightly sand when dry.
  3. Apply low-tack masking tape to skirting boards, architrave, and socket surrounds.
  4. Paint the ceiling first using a roller with an extension pole, working along the shortest edge.
  5. Cut in around the wall edges with a 2-inch angled cutting-in brush in manageable 1–2 metre sections.
  6. Roll the main wall areas in a "W" or "M" pattern to spread paint evenly without roller lines.
  7. Allow the first coat to dry completely (usually 2–4 hours) before applying the second coat.

Practical tips

  • Never press hard on the roller. Let the paint-saturated sleeve do the work.
  • Keep a wet edge: avoid letting cut-in edges dry before rolling the adjacent wall section.
  • Remove masking tape while the second coat is still slightly tacky to prevent tearing dry paint.
