Choosing the Right Paintbrush

Last Updated on February 17, 2023 by Jose Villegas Jr.

The brush or roller cover you select is one of the most crucial factors that can affect the result of any painting project. A poor choice of tool can doom your efforts, causing wasted time and frustration with the outcome. Conversely, selecting the right paintbrush can result in a smooth and even application of the paint.

It’s important to consider that your time is valuable, and attempting a project without the correct tools can end up being more costly in terms of both time and effort. This can lead to having to start all over again or being dissatisfied with the finished product. Regardless of whether you’re a novice or an experienced painter, it’s essential to have the appropriate paintbrush to ensure that your job is completed to your satisfaction.

There are a few key criteria to consider when selecting a paintbrush.

Using the wrong brush can quickly ruin a freshly painted room, leaving it looking streaky and making the job much more difficult. For example, using a polyester brush with an oil-based paint will cause the bristles to become limp and almost impossible to work with.

Before making a decision, keep these tips in mind when selecting paintbrushes:

1. Scope of the Project

When embarking on a paint project, it’s crucial to consider the project scope and the type of paint you’ll be using to determine the right paintbrush to use. The size of the room or surface you’re painting is an important factor in choosing a paintbrush. If you’re painting a large area, such as an entire wall or entryway, you’ll need a wider brush. However, if you’re painting a smaller area with more intricate details, such as window trim, crown molding, or chair rails, a narrower brush will be more appropriate.

To help you choose the best brush width, consider the following tips:

  • Small trim and window – 1 to 2-inch width
  • Doors and cabinets – 3-inch width
  • Large flat areas – 4 to 5-inch width

Choosing the right size brush is important as it can impact the overall quality of the finish. A smaller brush is easier to control and allows for greater precision, while a larger brush can hold more paint and help you complete the job more quickly.

2. Type of Paint

The type of paint you’re using is another important consideration when choosing a paintbrush. There are two main types of bristles to choose from: natural and synthetic. Natural bristle brushes are ideal for use with oil-based paints and are made from animal hair. These brushes work well for wood stain, varnish, urethane, and enamel-based paints. Bristles with split ends are best as they can hold more paint and release it evenly.

Synthetic bristle brushes, on the other hand, are the best choice for water-based latex paint, acrylic, and alkyd paints. These bristles are made from nylon, polyester, or a combination of both, and are stiffer than natural animal hair. They do not absorb water and are ideal for water-based paints and stains. Synthetic brushes offer great coverage and a smooth finish.

As you peruse the world of paint brushes, you may come across a variety of bristle types, each with its own degree of softness or stiffness. Typically, brushes are labeled as either soft or stiff. Soft bristles, in particular, are a suitable option when applying stains and varnishes.

The softness of natural bristles compared to synthetic ones is the primary reason why professionals often recommend natural bristle brushes for varnishes, urethanes, and oil-based paints. When using stiff bristles to apply these types of paint, the surface can dry with unsightly ridges that are distinctly noticeable. However, if you are painting intricate moldings or cutting around trim, a stiffer brush can provide you with greater paint control.

If you are new to the world of paintbrushes, it can be overwhelming to navigate the range of options. Understanding the differences in bristle softness can make a significant impact on the quality of your painting project. Remember, soft bristles are ideal for varnishes and stains, while stiffer bristles can be advantageous for more intricate applications.

3. Detail of Painted Surfaces

When selecting a paintbrush, it’s important to consider the details of the surfaces you’ll be painting. One factor to keep in mind is whether the brush has bristles that are cut blunt and parallel to the ferrule or cut at an angle. The bristle shape can have a significant impact on the final appearance of the project.

For flat surfaces without intricate molding and where you won’t need to cut in close to other painted areas, a straight-cut brush is the best option. Conversely, if you need to paint around trim, prepare a wall for rolling, or paint an edge, an angled brush is the better choice. Angled brushes are also ideal for moldings with intricate details that require shaping.

By choosing the right brush shape for your project, you can achieve a professional-looking finish. Take the time to consider the details of your painting job and select the brush that will work best for your needs.

4. Desired Results

The results of your painting project can depend not only on your painting technique but also on the quality of the tools you use, including your paintbrush. While standard-grade brushes are available at a lower cost, investing in good-quality brushes can make all the difference in achieving your desired results.

High-quality paintbrushes are designed with flagged bristles, which have split ends that help to grip the paint better and leave fewer brush marks on the surface. Although they may be more expensive, they are worth the investment, especially for larger and more noticeable areas. A top-notch brush can help you achieve a smooth finish and bring a professional look to your project.

It may be tempting to opt for cheaper brushes, but keep in mind that the quality of the brush will impact the overall quality of your project. Cheap brushes are suitable for quick touch-ups or small paint jobs that don’t require a high degree of finish. However, for larger, more important projects, it is best to invest in good-quality brushes. By properly cleaning and storing your brushes, they will last longer and provide great results for future projects.

Make Your Brushes Last

Properly caring for your paintbrushes is essential to ensure their longevity and maintain their performance across multiple projects. With the right care, quality paintbrushes can be used many times and provide a great return on investment.

After each use, it is important to clean your brushes thoroughly to avoid any residual paint drying on the bristles. While foam brushes and cheaper brushes can be disposed of after a single use, quality paintbrushes can be reused multiple times with proper cleaning.

When using a paintbrush correctly, no paint should be left in the brush’s belly, and only half of the bristles should contain paint. The type of solvent you use to clean your brush will depend on the type of paint you have used. The manufacturer’s instructions for cleaning the brush are usually printed on the paint can, and it’s best to follow those directions.

By taking the time to properly clean and store your paintbrushes after each use, you can extend their lifespan and maintain their quality, ensuring they will be ready for your next project.

Water-Soluble Paints

If you use water-soluble paints such as latex, it is important to clean your brushes properly to extend their life. You can use a specialized brush detergent, or regular dish detergent which is more affordable, to remove paint from the bristles. When cleaning, be sure to clean as high up into the bristle as possible. To do this, push the brush down onto a surface while rinsing with warm water. This will force the bristles to splay, allowing you to clean deep into the brush.

To remove any caked-on paint, use a sponge with a light-scrubbing surface to rub the bristles. Rinse the brush thoroughly with water, repeating the process until all the paint has been removed. For frequent painters, investing in a brush comb can be useful. This specialized tool has wide-set metal teeth designed to separate the bristles of a paintbrush, making it easier to clean.

Oil-Based Paint

Cleaning oil-based paint requires a different approach. Swirl the brush in a cup of paint thinner or lacquer thinner for 30 seconds, then wipe the brush on the side of the cup. You will need to repeat this process several times until no more paint comes out of the brush. Finally, wash the brush with soap and water and shake out the excess liquid. Allow the brush to dry completely, and then store it in the sleeve it came in.

To help the brush dry quickly and correctly, shake it a few times to align the bristles and hang it up to dry. This allows air to circulate around the bristles, ensuring that they dry evenly. After the brush has dried, store it in its original sleeve so that the bristles remain flat and protected. If you have purchased more expensive brushes, keep the cardboard covers that come with them and use them for storage.

By properly caring for your brushes, you can extend their lifespan and get many uses out of them. Take the time to clean and store them properly, and you’ll find that your brushes will last for years.

Conclusion

Choosing the right paintbrush is crucial for every painting project. The wrong brush can ruin the outcome, waste time and cause frustration. The main criteria for selecting the right paintbrush include the project scope, type of paint, detail of painted surfaces, and desired results.

The brush width should be selected based on the size of the surface and the degree of detail. Natural bristle brushes work best with oil-based paints, while synthetic bristle brushes are suitable for water-based latex paint, acrylic, and alkyl paints.

The shape of the brush bristle can also affect the overall look of the finished project. Investing in good quality brushes is essential for achieving a smooth finish, while cheaper brushes can be used for small touch-ups.
