How To 'Cut In' When Painting?

Cutting in when painting is the process of painting clean, straight lines along edges (like ceilings, corners, skirting boards, door frames, or window edges) without using painter’s tape. It gives a professional-looking finish and makes the job easier when rolling large areas.

Here’s a step-by-step guide on how to cut in properly:

🎯 What You’ll Need:

• Angled paintbrush (50–63mm is ideal)

  
  

• Paint tray or small bucket

  
  

• Damp cloth (for mistakes)

  
  

• Steady hand and patience!

✅ How to Cut In Like a Pro:

1. Use the Right Brush

• Angled sash brush (cutting-in brush) is best – it gives you better control for precision.

  
  

• Choose a quality brush with synthetic bristles (especially for water-based paints).

  
  

2. Don’t Overload the Brush

• Dip the brush about 1/3 of the way into the paint.

  
  

• Gently tap (don’t wipe) the brush against the side of the paint tray to remove excess.

  
  

• The brush should hold enough paint without dripping.

3. Start Slightly Away from the Edge

• Place the brush about 1cm (½ inch) away from the edge.

  
  

• Slowly drag the brush toward the edge, then run it along the edge in a straight line.

  
  

• Use long, smooth strokes for a clean line.

4. Feather the Paint Out

• Once the edge is painted, feather the paint away from the edge into the wall with lighter strokes.

  
  

• This makes blending with the roller easier and avoids a visible line.

  
  

5. Work in Small Sections

• Cut in about a metre at a time, then roll that section while the paint is still wet for a seamless finish.

  
  

• This avoids lap marks and helps the brushed and rolled areas blend better.

6. Steady Your Hand

• Hold the brush like a pencil for control.

  
  

• Rest your hand or pinky against the wall or a dry part of the trim for balance.

7. Clean Up Mistakes Immediately

• Keep a damp cloth or baby wipe nearby to clean up any slips quickly, especially on ceilings or trim.

  
  

• Optional: Use Painter’s Tape (if nervous)

  
  

• If you’re not confident freehand, you can use tape along the edges.

  
  

• Press it down firmly to prevent bleeding and remove it before the paint dries to avoid peeling.

🪄 Bonus Tips:

• Practice first on a hidden area if you’re unsure.

  
  

• Good lighting helps – use a lamp or work light if needed to see where you're painting.

  
  

• Use two coats – the first might not look perfect, but the second usually finishes the job beautifully.

  
  

• If painting next to a ceiling, try to keep the line just below the edge so you don’t accidentally touch the ceiling.
