How to Paint a Room from Start to Finish
A methodical approach to transforming a room with a clean, professional paint finish.
Repainting a room is the most rewarding way to refresh a home, yet the difference between an amateur result and a polished one lies almost entirely in the preparation and the order of work. Rushing straight to the roller is the single most common mistake.
In this guide we walk you through the full sequence, from clearing and protecting the space to the final coat, so that your finish is even, drip-free and built to last.
What you will need
- Dust sheets
- Low-tack decorator's tape
- Filler and filling knife
- Fine-grade sanding sponge
- Emulsion roller and tray
- 25mm and 50mm synthetic brushes
- Matt emulsion in your chosen shade
Clear and protect the space
Move furniture to the centre of the room and cover it with dust sheets, then lay sheets along the skirting. Remove switch plates and socket covers where safe to do so. Take down curtains and pictures so nothing interrupts your reach.
Clean and repair the surfaces
Wipe walls with a lightly dampened cloth to lift dust and grease, paying particular attention above radiators. Fill any cracks, dents or picture-hook holes with a quality filler and allow it to dry fully before sanding smooth. Dust off the residue with a clean, dry cloth.
Mask the edges
Run low-tack decorator's tape along skirting, architraves and the edges of the ceiling if you are not painting it. Press the tape down firmly with a filling knife so paint cannot bleed beneath it. Masking takes patience but saves hours of correction later.
Cut in the edges
Using a 50mm brush, paint a neat band around the perimeter of each wall, into the corners and around any fittings. Work in sections no longer than you can comfortably reach so the cut-in stays wet. This frames each wall ready for the roller.
Roll the main area
Load the roller evenly and apply the emulsion in overlapping W-shaped strokes, then lay off in light vertical passes to even out the texture. Keep a wet edge at all times to avoid visible joins. Work methodically from top to bottom and from the window wall outwards.
Apply the second coat
Allow the first coat to dry for the time stated on the tin, usually two to four hours. Repeat the cutting in and rolling for a second, more even coat. Most matt emulsions reach their true depth of colour only after this second application.
Remove tape and reinstate
Peel the masking tape away slowly at a shallow angle while the final coat is still slightly tacky to leave a crisp line. Refit switch plates once the paint is touch dry, then return furniture after a full day of curing. Keep the room ventilated throughout.
