How do I paint neat edges without tape?

Cutting in is a technique rather than a trick. A decent angled brush loaded correctly produces a straighter line than tape, faster, and without the risk of pulling paint off when the tape comes away.

What you'll need

• Angled sash brush, 50mm
• Paint kettle or small pot
• Damp cloth (optional)

Step by step

1. Use an angled sash brush rather than a flat one.The angled tip is what makes a clean line achievable. A cheap flat brush makes this far harder than it needs to be.
2. Decant paint into a small pot or kettle.Easier to control, and you are not carrying a full tin up a ladder.
3. Load only the first third of the bristles.Dip and tap off the excess — do not scrape it on the rim, which removes too much. An overloaded brush runs and drips.
4. Start the stroke about 5mm from the edge.Lay the paint down slightly away from the line first, so there is a reservoir to draw from.
5. Ease the brush towards the line so the bristles fan slightly.Light pressure fans the angled tip into a straight edge. This is the actual technique.
6. Draw one long steady pass rather than short strokes.Move your whole arm, not your wrist. Short dabs produce a wobbly line every time.
7. Work in sections of about a metre, keeping a wet edge.Then roll the main area while the cut-in band is still wet so the two blend without a visible band.
8. Wipe any overrun immediately with a damp cloth.Wet paint comes off instantly. Dried paint needs scraping and is much harder to correct.

Tips

• Practise on a section that will be covered later. Twenty minutes of practice makes a real difference to the whole job.
• If you do use tape, run a thin bead of the base colour along the edge first and let it dry — it seals the gap so the top colour cannot bleed under.
• Remove tape while the paint is still slightly wet, pulling back at a shallow angle. Fully dried paint tears at the edge.

Common mistakes

• Overloading the brush — It runs down the wall, drips off the ceiling and makes a controlled line impossible.
• Painting with wrist movements — The wrist pivots, which makes an arc. Moving from the shoulder is what produces a straight line.
• Letting the cut-in band dry before rolling — The different application methods show as a visible band. Roll into it while it is still wet.
