- Time
- Half a day to two days, plus drying time
- Safety level
- Standard checks
This guide is a starting point, not a survey of your home. Check the actual surface, hidden services, product instructions and local requirements before work. Stop when a safety condition or professional checkpoint applies.
Materials
- Wall paint in the chosen colour and finish
- Primer or stain blocker only where the surface needs it
- Filler and paintable caulk for suitable small defects
- Low-tack masking tape
- Floor covering or dust sheets
- Cleaning solution recommended for the surface
Tools
- Paint scraper and filling knife
- Sanding block with suitable abrasive and dust control
- Paint brush for edges
- Roller, sleeve, tray and extension pole
- Stable step platform if the upper edge cannot be reached from the floor
Preparation
- Confirm the wall is dry, stable and free from active mould or leaks.
- Move furniture, cover the floor and remove or protect fittings without disturbing fixed wiring.
- Clean the wall, fill stable defects and allow repairs to dry before sanding.
- Check the paint label for surface compatibility, coverage, ventilation and drying time.
Safety
- Do not sand or scrape a coating that may contain lead or another hazardous material.
- Ventilate the room and keep children and pets away from wet paint and tools.
- Use stable access equipment; do not stretch from chairs or work above a stairwell.
Steps
Protect the room
Cover the floor, move furniture, mask clean edges and keep a clear route to the door.
Prepare the surface
Clean, scrape only loose material, fill stable marks and sand the dried repairs smooth with dust control.
Safety checkpoint: Stop if the wall is damp, crumbling, mouldy or the old coating may be hazardous.
Prime where needed
Spot-prime bare repairs or apply the specified primer where the paint maker requires it.
Cut in and roll
Brush manageable edge sections, then roll the adjoining area while the edge is still workable.
Apply the finish coat
Let the first coat dry for the stated time, inspect in good light and apply the next coat evenly.
Remove protection
Remove tape at the paint maker's recommended stage, let the finish cure and refit only safe removable items.
Professional checkpoints
- Use a specialist if there is persistent damp, extensive mould, unstable plaster or a suspected hazardous coating.
- Use a qualified electrician for any change to fixed switches, sockets or wiring.
Visual guidance
Level: not-needed
A clear checklist is normally enough for a straightforward repaint. A preview can still help with colour choice.
