Good preparation makes paint easier to apply, improves adhesion and leaves a cleaner finish. The exact sequence changes with the surface, but these are the essentials for a typical interior repaint.
Before opening the tin
- Move furniture or cover it with reusable dust sheets.
- Remove wall fittings where safe, or mask them neatly.
- Wash greasy or dirty areas with an appropriate cleaner and let them dry.
- Scrape loose paint and investigate flaking, stains or damp rather than covering them.
- Fill cracks and holes with compatible filler; allow it to dry fully.
- Sand repairs smooth, then remove dust with a vacuum or damp cloth.
- Mask edges you do not want to paint, including sockets, trim and floors.
- Spot-prime bare patches or use a full primer where the product system calls for it.
Set up the room for success
Use steady ventilation, safe lighting and a sensible order: ceilings first, walls next, then trim if your paint system calls for it. Keep tools, touch-up paint and cleaning materials together. Do not paint over active damp, mould or a surface that has not dried after cleaning.
Helpful supplies
Most rooms need roller sleeves, an angled brush, tray liners, masking tape, floor protection, filler and abrasive paper. The Paintwise calculator lists suggested supplies based on the project so first-time painters do not have to guess.
