Before you start
Good preparation is 80% of a professional-looking paint job. Rushing the prep is the number one reason DIY painting looks amateur.
You need: emulsion paint, a roller and tray, a 2-inch angled brush for cutting in, masking tape, dust sheets, filler, and sandpaper.
Tools needed
- !Emulsion paint — buy: £15–30 per tin, choose the correct finish (matt for walls, silk for high-moisture rooms)
- !Roller, roller sleeve and tray — buy: £8–15 as a set
- !2-inch angled cutting-in brush — buy: £3–6, essential for clean edges
- !Masking tape — buy: £2–5 per roll
- !Dust sheets — buy or borrow: old bedsheets work fine too
- ✓Sandpaper and ready-mixed filler — for wall preparation
Prepare the room
Move furniture to the centre and cover with dust sheets. Remove switch plates and socket covers. Lay dust sheets on the floor and tape them to the skirting boards.
Where beginners go wrong
Skipping the fill and sand step — every imperfection in the wall shows up under fresh paint.
Applying paint too thickly in one coat, which causes drips and uneven drying.
Leaving masking tape on too long — if paint dries fully on the tape, it can peel the new paint when removed. Remove tape while the final coat is still slightly tacky.
Stop and call a decorator if...
There is damp on the walls — paint will not adhere and the problem will return
You see mould under the old paint — this needs treatment before redecorating
The walls have extensive cracking that suggests a structural issue

⚠️ Watch out if you rent
You need your landlord's written permission to repaint. Some allow it — but may require you to repaint in the original colour before you leave. Get this agreed in writing before you buy any paint.
