If you’re wondering how to choose a paint brush or trying to understand the differences between paint brush types, this post is for you.

Why Choosing the Right Paint Brush Matters

Not all brushes are created equal. The right brush improves paint flow and coverage, enhances precision and control, reduces drips and streaks and helps avoid unnecessary paint wastage. Whether you’re painting a whole room or precision painting around corners, matching the paint brush to the surface and paint type is the key to professional-looking results.

The Best Paint Brush for Your Project

If you’re deciding which paint brushes to purchase, start by thinking about the surface you’re painting on and the type of paint you’re using.

1. Match the bristle type to your paint:

• Synthetic bristles are best for water-based paints.
• Natural bristles work well with oil-based paints.

2. Pick the right brush shape and size:

• Use a flat brush for large, smooth areas like walls.
• Choose a sash brush or angled sash cutter brush for corners, edges and trim.

3. Consider the handle and grip:

• Long handles give better reach.
• Shorter handles provide more control in tight spaces.

4. Check paint load and release:

• A high-quality house paint brush holds more paint and releases it evenly for fewer strokes.

Which Bristles to Choose: Stiff or Soft?

Paint Brush Types and Their Uses Explained

Understanding the types of paint brushes and their uses will help you choose the right one:

• Wall Brush (Flat): When you have a lot of surface to cover, a flat wall brush is ideal, particularly for surfaces like walls and ceilings. These brushes hold more paint and reduce painting fatigue as they enable longer strokes. This should be your go-to paint brush for wall painting. 
• Rollers: While not technically brushes, rollers are essential tools for painting large, flat areas quickly and evenly. They are ideal for walls, ceilings and exterior surfaces where speed and smooth coverage are priorities. Rollers need quality roller covers and are best paired with a brush for precision work around edges and trim. You could also use paint applicators if you’re not confident using a brush or roller. 
• Sash Brush: If you’ve been wondering what is a sash brush, it has thinner bristles and is designed for trim and detailed work like windows, skirting boards and frames. A sash brush can have either a flat or angled shape, offering more control in tighter areas where precision counts.
• Angular Brush (Sash Cutter): Wondering what is a sash cutter brush? It’s a type of sash brush with angled bristles, also known as a sash cutter brush. It's perfect for cutting in along edges and corners where precision is key.
• Sash Cutter vs Wall Brush: A sash cutter offers precision, while a wall brush is made for coverage. Use them together for best results.
• Round Brush: Best used for detailed work on mouldings, balusters or furniture with curved or uneven surfaces. Unlike an angular brush, which is ideal for straight lines and corners, a round brush provides more flexibility and control on rounded or intricate shapes.
• Sample Pot or Small Brush: Perfect for test swatches or intricate sections like mouldings.

These are the core types of brushes for painting walls and general surfaces. Each is suited to a different task, so you should assess the painting project before buying brushes to make sure you purchase what you need to get the job done to a high standard.

Wall or Sash (Trim)

WALL brushes are for longer strokes and help you cover more surface which makes them perfect for painting walls or ceilings. They have thicker bristles or filaments to hold more paint. Wall brushes are also designed with larger, thicker handles to reduce fatigue and assist in getting a nice long, smooth paint stroke.

SASH brushes are designed to be used on all the trim areas of the house like doors, windows, door frames, skirting boards, gutters, etc. They have less filament or bristles than a wall brush and therefore don’t hold as much paint, allowing greater precision and control.

Angled brushes are also available, these do everything a straight edge sash or trim brush will do, but some people prefer the control an angled filament gives them.
