How to choose the best paint brushes for walls

Bristles are the working heart of any paint brush, and different types suit different paints.

• Natural bristles are made from animal hair, typically hog or ox. They work beautifully with oil-based paints and varnishes because their structure holds and releases thicker formulas evenly. However, natural bristles absorb water and lose their shape with water-based paints, so they're not ideal for emulsion. These aren't available from Harris, as all of our paintbrush are made from long-lasting synthetic materials.

• Synthetic bristles – made from nylon, polyester, or a blend – are the go-to choice for water-based paints, which make up the vast majority of wall paints today. They maintain their shape, don't absorb water, and clean up easily. Quality synthetic bristles also resist wear, meaning fewer stray hairs on your freshly painted walls.

Harris Tip: All Harris wall brushes feature synthetic bristles specifically designed for water-based emulsions. If you're painting interior walls, synthetic is almost always the right choice.

Brush width determines how much wall you can cover with each stroke, but remember – bigger isn't always better. You should always fit the paint brush size to the job, not the other way around. 

• Larger brushes (3–4 inches) cover broad, open wall areas quickly. They're efficient for filling in sections after you've cut in around the edges.

• Medium brushes (2–3 inches) offer a balance between speed and control, making them versatile for most wall painting tasks.

• Smaller brushes (1–2 inches) provide precision for cutting in along ceilings, skirting boards, window frames, and corners where accuracy matters more than speed.

Harris Recommendation: A brush set covering multiple sizes gives you flexibility for every stage of the job. The Essentials Walls & Ceilings Paint Brush 3 pack or Ultimate Blade Paint Brushes 3 pack provide a practical range for tackling walls from edge to centre.

The shape of your brush will affect how it handles different areas of a wall and how precise your painting will be.

• Flat brushes have a straight, squared-off edge. They're excellent for loading plenty of paint and covering large, flat sections efficiently.

• Angled brushes feature a slanted tip that creates cleaner lines when cutting in. The angle allows you to see exactly where the bristles meet the wall, giving you greater control along edges, corners, and where walls meet ceilings.

Harris Options: For precision work, the Seriously Good Angled Paint Brush in 1 inch or 2 inch sizes helps you achieve crisp lines with less effort. The Ultimate Blade Paint Brushes (1–3 in) use a unique design for exceptionally clean, precise edges.

When you're painting for hours, handle design matters more than you might expect.

• Rattail handles are long, slim, and pencil-like. They suit detailed work where you need a light, precise grip – think cutting in and edging rather than covering large areas.

• Beavertail or fluted handles are wider and shaped to fit the palm of your hand. They reduce fatigue during extended painting sessions and give you more control when applying pressure across bigger sections of wall.

Harris features: Seriously Good brushes include a soft-grip handle designed for comfort during longer decorating sessions. Ultimate brushes feature FSC®-certified wooden handles, ergonomically shaped for balance and reduced hand strain.

Your wall's texture will influence your brush and roller choices, meaning you should pay careful attention to what type of surface you’ll be painting.

• Smooth walls (standard plasterboard, skim-coated plaster) work well with shorter bristles and medium pile rollers. These apply paint evenly without leaving excess texture behind.

• Textured surfaces (stucco, exposed brick, artex, rough plaster) need tools that can work paint into uneven surfaces. 

Harris Recommendation: For textured walls, the Ultimate Long Pile Roller Sleeve provides excellent coverage. For smooth walls and ceilings, the Ultimate Medium Pile Roller Set delivers a neat, even finish.

Looking after your brushes properly extends their life and keeps them performing at their best long after purchasing. Follow these steps after each painting session:

1. Remove excess paint by scraping the bristles gently against the rim of your paint tin or a piece of cardboard.

2. For water-based paints, rinse the brush in a clean bucket of water. 

3. For oil-based paints, use an appropriate brush cleaner or white spirit. Work the solvent through the bristles thoroughly, then rinse. 

4. Reshape the bristles with your fingers while still damp.

5. Lay the brush flat or hang it upside down to dry – never rest it on its bristles, as this bends them out of shape.

Harris tip: Store clean, dry brushes in their original packaging or wrap them in paper to protect the bristle shape between projects. Proper care means your brushes will be ready whenever inspiration strikes. Browse the full range of Harris wall brushes to find your perfect match.
