When it comes to finishing a woodworking project, using the right brush can make all the difference. Polyurethane is a popular choice for protecting and enhancing the natural beauty of wood, but not all brushes are suited for polyurethane. Besides a synthetic brush is best for water-based poly.
In this article, we’ll take a look at the best brushes for polyurethane and the different types of bristles, shapes, and sizes that will help you achieve a professional-looking finish. Whether you’re a DIY enthusiast or a professional woodworker, this guide will help you choose the perfect brush for your next project.

Using cheap disposable brushes can be messy, leaving behind streaks and brush marks that require touch-ups. However, with the Purdy Dale Angular Trim Brush, you won't have to worry about that.

Finishing a trim
When it comes to finishing a trim, using the right brush can make all the difference. A smaller brush, around 2 inches, is ideal for this task. The bristles of the brush should be slanted at an angle to allow for easy cut-ins. A good trim brush not only enables you to apply the paint or stain precisely to the trim, but it also helps to create a smooth finish.
Moreover, a trim brush can also be used as a cut-in brush when applying polyurethane to floors using other polyurethane applicators. In this case, a trim brush can help you apply the polyurethane in tight corners and hard-to-reach areas, ensuring a seamless finish.
Investing in a high-quality trim brush can save you time and money in the long run. Cheaper brushes tend to shed bristles, resulting in a less-than-perfect finish.

What type of Brush for polyurethane
When it comes to brushes, there are typically two categories based on the bristles they use: natural bristle and synthetic bristle brushes. It’s important to note that water-based polyurethane requires a synthetic brush due to the nature of the material. Natural bristles can become soft and uncontrollable when dipped in water, making them less ideal for this type of finish. However, natural bristle brushes can be a great option for solvent-based finishes. It’s worth noting that synthetic bristle brushes are typically stiffer than natural bristle brushes, which can make them more effective for applying certain types of finishes.
What to look for when buying a polyurethane brush
To achieve a smooth and even finish, a brush should possess three key qualities: tapered bristles, flagged ends, and a chisel shape. Let’s explore each of these qualities in more detail below.
Tapered bristles refer to bristles that gradually become thinner towards the tip of the brush. This allows the brush to hold more finish, which can result in fewer brush strokes and a smoother finish overall.
Flagged ends are bristles that have been split at the end to create a soft, feather-like tip. This helps the brush to release the finish more evenly and reduces the likelihood of leaving visible brush marks on the surface.
A chisel shape
A chisel shape refers to a brush that has flat bristles with angled edges. This shape allows for greater precision and control when applying the finish, especially when working in tight or detailed areas.
When these three qualities are present in a brush, it can help ensure a professional-looking finish with minimal effort. It’s worth investing in a high-quality finishing brush that possesses these qualities to achieve the best results possible.
