Paint a room

Save £200–500 in 1 day — no decorator needed

Most people hire a decorator for this. You probably don't need to.

Last updated: January 2025

Only basic tools needed — most homes already have them.

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.

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.

Most people get this done in under 5 minutes.

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

What you just learned

You now know how to prepare, cut in, and roll a wall to a professional standard. These skills transfer to painting ceilings, woodwork, and eventually more advanced techniques like colour blocking and feature walls.

Most people would pay a tradesperson for this.

⚠️ 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.

How long will this actually take me?

First time

1.5–2 days

With experience

1 day

Prep — filling, sanding, cleaning — takes longer than the painting itself. Don't skip it.
