Selecting the Best Brushes for Oil and Acrylic Painting

Finding the right brushes for your artwork can be quite a challenge. Many brushes are either too flimsy or don’t maintain their fine point for detailed oil painting work. Additionally, cheaper brushes often shed bristles, which can create unwanted messes in your paintings. After trying out various brushes, I have gathered some insights on how to choose the best tools for your oil and acrylic painting process, how to care for them, and which brands you might consider.

Brush Types and Sizes for Painting

Brushes come in a wide range of sizes, shapes, and bristle types. Understanding these variations can help you select the right brush for each stage of your artwork.

Brush Size

Brush size is indicated by a number written on the handle. The higher the number, the larger the brush. For example, brushes numbered #0000 to #0 are ideal for detailed work, while #2 to #4 brushes are suited for small applications. Brushes sized #6 to #10+ are better for general coverage of paint on the canvas.

Brush Shape

Brush shapes play a major role in the type of strokes they produce. There are several types of brush shapes:

Rounds: These brushes have a fine point and are excellent for detailed work.
Flats: These brushes create wide strokes and are ideal for covering large areas.
Liners: These are great for fine lines and intricate details.
Filberts: My personal favorite, as they provide versatile strokes—flat strokes or thin lines, depending on the angle.
Fans: These brushes are excellent for blending edges and creating texture, such as foliage in landscape paintings.

Choosing the Right Brush for Oil & Acrylic Painting

Types of Brushes

In general, brushes designed for watercolor painting are too soft for oil painting, as they don’t maintain the required point for oil paints. However, small round Kolinsky brushes work well for intricate details in oil painting. For larger blending tasks, watercolor 1-inch flats can soften areas after the paint is applied.

There are three main categories of brushes suitable for oil and acrylic painting:

Bristle Brushes: Known for their stiffness, these are perfect for underpainting.
Synthetic Brushes: These offer flexibility and precision, suitable for refined layers.
Synthetic-Sable Blend Brushes: A combination of synthetic and sable bristles, offering durability and softness.

First Layer: Bristle Brushes

When starting your painting, use stiff bristle brushes to apply the first, rough layer of paint. This layer typically doesn’t blend smoothly, so the stiffer bristles help spread the paint efficiently. I recommend using solvents like Gamsol mixed into the paint to improve the flow. However, this can wear out finer brushes. Bristle brushes are the most effective for the first layer on canvas, though they may be too harsh for painting on panels.

Second Layer: Synthetic Brushes

As you begin painting over the initial layer, synthetic brushes are better suited for smoother application and refining details. Brushes like the "Simply Simmons" range from Michael’s are affordable and durable, maintaining a fine point. However, low-quality, unbranded craft brushes may not provide the necessary stiffness to move paint around or create precise edges.

For this stage, I use Robert Simmons brushes, particularly #2 rounds and #2-4 filberts. These brushes are cost-effective and provide good quality for the price, lasting about a year with regular use. If I need a specific size or tip, I can easily purchase individual brushes. Another great option is Rosemary & Co brushes, which are known for their high performance in oil painting.

Third Layer: Synthetic and Sable Brushes

For the final layers, when the painting requires delicate transitions, texture, and intricate details, a good set of brushes is essential. For detailed work, I recommend Ebony Splendor brushes by Creative Mark, as they are budget-friendly yet highly effective for small-scale tasks. However, the best brushes for this stage are from Rosemary & Co, offering a wide selection of top-quality brushes designed for fine details in oil paintings.

Final Thoughts on Brush Selection

To achieve the best results in your oil and acrylic paintings, invest in high-quality brushes that suit each layer of your painting process. Whether you are applying an underpainting with stiff bristle brushes or refining details with synthetic and sable blends, choosing the right tool will ensure that your work shines. Keep in mind that proper care and cleaning of your brushes will extend their life and maintain their performance.
