Skip the masking tape! This Japanese painting trick lets you stay within the lines and finish in half the time
Speed matters in home improvement. A method known as “cutting-in”, originating in Japan, is being used more in 2026. It produces clean, precise lines without the need for masking tape.
How it saves time
Traditionally, painting involved laying masking tape along edges to get clean lines. On a room of 20 m², preparation and tape removal can add several hours; with older methods it could take up to 8 hours in total. Cutting-in offers an alternative that can cut that time.
The method uses an angled-cut edging brush with synthetic-fibre bristles. Load the brush lightly, keep it moving smoothly along the edge and don’t stop mid-stroke. When done well, cutting-in can halve the overall painting time, bringing it down to roughly 3 to 5 hours.
Where it comes from and how it works
Cutting-in is not new; it is a time-honoured Japanese tradition now used internationally. It is employed by professional decorators, DIY enthusiasts and interior designers. In 2026, some people adopt it to reduce material waste such as masking tape.
The technique is straightforward and requires only modest equipment. Use an angled-cut edging brush; cheap ones can lose their shape and leave streaks, affecting the finish. Like any skill, cutting-in takes practice; once mastered, it is as fast as tape-based methods and produces sharper edges.
Practical tips and common mistakes
There are times when masking is still useful, especially for very intricate details (for example, ornate mouldings). If you do use tape, apply it without wrinkles and remove it while the paint is slightly damp. The right removal angle and motion will prevent the paint from tearing or the edges from fraying.
Choosing the right materials matters too. Match the nap on your rollers to the wall texture to avoid splatter, and make sure surfaces are clean and properly primed; that helps prevent problems like poor adhesion or an uneven finish.
What professionals say and what comes next
Some professional painters favour skill over kit and skip tape entirely, relying on steady hands and suitable brushes. They regard cutting-in as a craft that, with practice, improves both speed and the appearance of a room.
Interior designers provide guidance on how to style freshly painted spaces. Combining the method with design advice offers a practical approach to refreshing a home and provides clear benefits for homeowners.
Given its growing use, consider trying cutting-in. It can make painting quicker and neater while helping you develop the necessary technique.
