Applying a finish like polyurethane is an essential step in woodworking and can protect furniture and floors while enhancing the wood’s natural beauty. The right application tool is crucial for a smooth, flawless finish. Brushes specifically designed for polyurethane applications offer an effective way to achieve that professional look. These brushes come in different materials such as natural bristle, synthetic filament, or a blend of both, each serving a specific purpose.
When choosing the best paint brush for applying polyurethane, it’s vital to consider the type of polyurethane you’ll be using—water-based or oil-based. For water-based polyurethane, a synthetic brush made of nylon or polyester is often preferred as it won’t absorb water and will maintain its shape. Oil-based polyurethane requires a natural bristle brush which is resilient and can hold the heavier oil-based product without drooping.
The size of the brush also makes a difference; a larger brush covers more area, which is ideal for big projects like floors. Conversely, a smaller brush gives you more control for intricate work like furniture. Alongside size and bristle material, the brush’s quality can greatly influence the outcome. A high-quality brush with fine tips can minimize streaking and brush marks, leading to a smoother finish.
Choosing the right brush can elevate the final outcome of your project. We’ve considered a range of factors from bristle type to brush width to identify the most reliable brushes for polyurethane application, ensuring a professional result every time.
Top-Rated Paint Brushes for Polyurethane
We’ve meticulously searched and tested to bring you our top picks for paint brushes specifically suited for polyurethane application. Our selection ensures smooth coverage and a professional finish, whether you’re a seasoned woodworker or tackling a DIY project. The brushes listed here are designed to minimize strokes and resist shedding, making your work clean and efficient.
1. Minwax 2″ Poly Brush
We think this brush is ideal for anyone seeking a superior finish with polyurethane.
Pros
- Leaves a smooth, glass-like finish
- Excellent for holding and applying polyurethane
- Durable with a stainless steel ferrule
Cons
- May shed bristles
- Not suitable for water-based polyurethane
- Can be difficult to clean
During our recent project, we found that the Minwax 2″ Poly Brush handled beautifully. The bristles held just the right amount of polyurethane offering control and even distribution. As we glided over the wood surface, the bristles moved smoothly, leaving behind a finish that had us admiring our reflection in its shine.
However, our delight was slightly tempered when a few bristles decided to part ways with the brush. While not a dealbreaker, it did mean some extra time picking out strays from the finish. Despite that, the overall quality of the work remained uncompromised.
Cleaning the brush post-application is always the part we’re less fond of. Polyurethane can be tenacious, and if not thoroughly cleaned immediately, the brush is apt to stiffen up. We recommend using mineral spirits for cleanup right after use to maintain the brush in top shape.
Overall, the Minwax 2″ Poly Brush excels for oil-based poly finishes and truly shines for final touch-ups and smaller projects where precision is key. Keep these insights in mind and you’ll find that this brush could very well be the ally you need for that smooth, enviable finish.
2. Tru Lamb 2″ Lambskin Brush
If you’re looking for a natural and efficient way to apply polyurethane, this lamb’s wool brush from Tru Lamb might be your new go-to tool.
Pros
- Natural lambskin picks up and releases polyurethane smoothly
- Shed-resistant, which minimizes mess during application
- Easy to clean and can be reused multiple times
Cons
- Initial shedding may occur before it reaches its non-shedding state
- May require a period of adjustment to get used to the lamb’s wool
- Priced higher than synthetic brushes
We recently had the chance to try the Tru Lamb 2″ Lambskin Brush on a set of hardwood floors, and the results were impressive. The natural lambskin really does hold and release polyurethane evenly, giving a lustrous, bubble-free finish. Thanks to its absorbency, we could cover a decent amount of surface without frequently dipping back into the can, saving time and reducing drips.
Despite the initial skepticism, the promises of being shed-resistant became evident quickly. No stray fibers were left behind, which is crucial when working on fine finishes. Cleaning was straightforward as well, and the brush maintained its shape after a rinse and spin, ready to tackle the next project.
While the price point is above some other options on the market, it’s clear that the investment pays off in the quality of the finish and the durability of the brush itself. This brush suits professionals and DIY enthusiasts who prioritize a superior finish and tool longevity.
3. Pro Grade 5-Pack Brush Set
For a mix of quality and affordability in your next project, this brush set delivers on both fronts.
Pros
- Versatile for different paint types and projects
- Good paint pick-up and release with fewer streaks
- Easy to clean and maintain
Cons
- Durability may not match professional-grade brushes
- Some bristle shedding possible
- Handles prone to wear over time
Finishing my latest piece with the Pro Grade Brush Set gave me appreciable results. The brushes felt comfortable in my hand, and the bristles moved smoothly across the surface. Whether edging along trim or covering broad wall spaces, I found these brushes adapted well to my varied strokes. Their performance was surprisingly good, especially considering they come with a lower price tag.
During my project, I noticed the brush set worked effectively with the multiple paint types I was alternating between. The bristles held acrylic and oil-based paints alike without issue, which made transitions between materials hassle-free. I was also impressed by the minimal streaking, attributing a clean finish to the sturdy bristle design of each brush.
Despite the initial worries about longevity, these brushes held up during several washes. Cleanup was simple, although I did spot a few loose bristles, which is common with non-professional brushes over time. The wooden handles were firm but may not withstand the wear and tear of heavy duty use over many years. Yet, for the casual DIYer or those painting projects not requiring the finest detail, we find ourselves reaching for this brush set again.
Buying Guide
Types of Brushes
When we’re looking to apply polyurethane, we should consider the type of brush that will suit our project. Generally, there are two types:
- Natural Bristle Brushes: They are perfect for oil-based polyurethane. The bristles are made from animal hair which holds the finish well.
- Synthetic Bristle Brushes: These are ideal for water-based polyurethane. The bristles don’t absorb water, preventing them from swelling and losing their shape.
Bristle Shape
The shape of the brush’s bristles affects the smoothness of the finish:
- Flat Bristles: Offer a wide application, suitable for larger surfaces.
- Tapered Bristles: Allow for more control and precision, which is good for edges and corners.
Bristle Quality
We must look for bristles that have “flagged” tips, which hold more finish for a smoother application. Higher-quality bristles will not shed into our finish.
Comfort and Grip
The handle of the brush should fit comfortably in our hand and help us maintain control while applying the polyurethane. A good grip enables us to apply with consistent pressure.
Size
Our choice of brush size depends on our project’s scale:
| Surface Type | Recommended Brush Size |
|---|---|
| Large Area | 3” to 4” |
| Medium Area | 2” to 3” |
| Small Area | 1” to 2” |
Maintenance
Consider brushes that are easy to clean. Water-based polyurethane comes off with soap and water, but oil-based requires a solvent for cleaning.
Remember, the best brush for polyurethane is the one that fits our project needs, so we assess the size of our project, the type of polyurethane we’re using, and how much control we need over the application.
