Choosing the right paintbrush can make a noticeable difference in how your paint job turns out. But, with so many options on the shelves, it’s easy to feel a bit lost. In the video above, Ask This Old House painter Mauro Henrique shares what to look for when picking a paintbrush, covering materials, shape, and size. We’ll dive deeper into the logistics below.
Paintbrush Materials
The type of bristles in a paintbrush affects how well it works with different paints. Getting the right brush material will help you achieve better coverage and a smoother finish.
- Natural hair brushes: Made from animal hair like hog bristles, natural brushes (also called China bristle) are perfect for oil-based paints. They hold more paint and spread it evenly, leaving a smooth finish. However, these brushes don’t work well with water-based paints and can be damaged by them.
- Synthetic hair brushes: Synthetic brushes, typically made from polyester, nylon, or a blend of fibers, are versatile and can handle both water- and oil-based paints. They hold their shape, are easy to clean, and work well with most paints, including latex and acrylic. Henrique recommends these brushes for most painting jobs.
- Foam brushes: Foam brushes are inexpensive and disposable, making them good for small touch-ups or single-use jobs. While they’re not meant for larger projects, they’re handy for getting a smooth finish in a pinch.
Paintbrush Shape
The shape of a paintbrush affects its performance in different painting scenarios. Understanding when to use angled or flat brushes can improve your painting results.
- Angled brushes: Angled brushes are great for detail work, like cutting in around windows, doors, or trim. The slanted bristles offer better control, allowing you to paint straight lines and detailed edges with precision.
- Flat brushes: Flat brushes are better for broad, flat surfaces like walls and siding. Their wide shape helps you cover more area with each stroke, making larger projects go faster.
Pro Tip: Jeff Young, professional painter, recommends matching brush shape to your task: “Generally I prefer a square cut if you’re doing large, large amounts of surface. If you’re painting clapboards on a house, barn board, you want a nice something that you can go back and forth, apply major amount of paint. The angle brush tends to be used for more detail oriented things like windows. If you have to get into corners and where you really want to have a nice careful line, this gives you a lot more control.”
Paintbrush Size
Picking the right brush size can make your painting more efficient. Here’s how to choose:
- Small brushes (1–2 inches): These brushes are ideal for detail work like painting narrow surfaces, window sashes, and small trim pieces. They’re also useful for touch-ups and small projects.
- Medium brushes (2-and-1/2–3 inches): These are great for doors, window casings, and baseboards, offering a balance of coverage and control.
- Large brushes (4 inches and up): Meant for large, flat areas like walls and siding, large brushes cover more surface area with fewer strokes, helping you finish big projects quickly.
Pro Tip: Painting contractor John Dee, who has painted a number of This Old House projects, advises matching your brush width to the surface: “A thick, 4-inch-wide brush with long bristles would be perfect for coating clapboards but useless on narrow window muntins.” For windows, Dee chooses a thin, 2-inch-wide brush with a long handle and shorter, more easily controlled bristles. “I’m always trying to strike a balance between precision and productivity,” Dee says. “The more you have of one, the less you get of the other.”
The Importance of Paintbrush Quality
While it’s tempting to grab the cheapest option, investing in high-quality paintbrushes can make a big difference in your painting results and long-term value. Here are some benefits of premium brushes:
- Better paint distribution and smoother finish
- Improved control and precision
- Longer lifespan with proper care and maintenance
- Reduced bristle shedding during painting
Quality paintbrushes often have distinctive features that set them apart from lower-end options: Copper or stainless steel ferrules offer better bristle retention, and dense, well-secured bristles maintain their shape. High-quality brushes often have comfortable, ergonomic handles for extended use and tapered bristle tips for smoother paint applications.
While high-quality brushes may have a higher upfront cost, their durability and performance make them a worthwhile investment for both DIY enthusiasts and professional painters.
According to This Old House Magazine, the ultimate test of a brush’s quality is how well it picks up and releases paint. To check a brush before buying, look at it in profile — the tips should come to a tapered point for better control. Then pinch the bristles between your fingers near their base. If they feel thin, you’ll be reloading that brush constantly. Finally, tug on the bristles: if they come out in your hand, they’ll come out in the paint.
Pro Tip: Painting contractor John Dee, who has painted a number of This Old House projects, emphasizes: “Without a good brush, it doesn’t matter how experienced a painter you are. You can’t control the paint.”
Paintbrush Care and Maintenance
Proper care and maintenance of your paintbrushes will keep them in top shape, allowing you to reuse them for multiple projects while maintaining their performance. A well-maintained brush not only gives you better results but also saves you money in the long run since you won’t need to replace them as often. Here’s how to take care of your brushes to extend their lifespan.
Cleaning Your Brushes
Clean your paintbrushes after each use. To clean off water-based paints like latex or acrylic, warm soapy water is usually all you need. Rinse the brush until the water runs clear, making sure to remove all paint from the bristles, ferrule (the metal part), and handle. For oil-based paints, use a solvent such as mineral spirits or paint thinner. Swirl the brush in the solvent, then rinse it in clean water before allowing it to dry.
Shaping the Bristles
Once the brush is clean, reshape the bristles by gently pulling them together so they return to their original form. This step prevents the bristles from fraying or bending while drying. If you skip it, the brush may lose its precision, making it harder to use on future projects.
Storage Tips
Once your brush is completely dry, store it in a cool, dry place. Avoid tossing it into a toolbox or drawer where the bristles can get bent or damaged. Many professional painters recommend using the original packaging or a brush cover to keep the bristles protected and in shape. This also helps keep dust and dirt from settling in the bristles, which can interfere with future paint jobs.
Pro Tip: Mario, a painting expert on This Old House, advises against using harsh tools on your brushes: “Wire brush is not good at all. You’re gonna damage the ferrule and also you’re gonna damage the bristles.” Instead of a wire brush, he recommends using a gentle scrub pad to remove any remaining paint near the ferrule — a far less aggressive approach that keeps bristles intact.
Our Conclusion
To choose the best brush for your painting project, factor in bristle material, shape, size, and quality. By selecting the right brush for your painting needs, you’ll achieve better results and a more professional finish. Investing in high-quality brushes and maintaining them properly can lead to long-term savings and improved painting experiences.
