What Paint Brush Should I use in cutting in?

Achieving clean, sharp lines along edges and corners- commonly known as “cutting in”- comes down to using the right brush and technique. For the best control and precision, a high-quality angled sash brush in the 2” to 2.5” range is the professional standard.

The angled design allows you to naturally guide the brush along tight areas, making it ideal for detailed work such as:

• Wall-to-ceiling lines
• Inside corners
• Around trim, windows, and baseboards

For a smooth, professional finish, consider using premium brushes like the Benjamin Moore Professional Angle Sash Brush or high-quality synthetic brushes designed for water-based paints. These brushes hold their shape, release paint evenly, and help reduce brush marks.

The angled tip is what gives you that crisp, straight edge without the need for excessive taping, saving both time and effort while improving overall results.

Pro Tips for Perfect Cutting In:

• Dip only about one-third of the bristle length into the paint to maintain control and prevent drips
• Avoid overloading the brush- too much paint makes it harder to achieve clean lines
• Use a steady, controlled hand and let the angle of the brush do the work
• Always cut in your edges before rolling the walls to ensure a seamless, blended finish

Taking the time to use the right brush and proper technique will make a noticeable difference in the final look of your project, giving you sharp lines and a clean, professional appearance.

Summary: Use a 2”- 2.5” angled sash brush for cutting in. It provides better control, cleaner lines, and a more professional finish- especially when paired with proper technique.
