Buying Guide: How To Choose The Right Polyurethane Brush
Polyurethane finishes demand brushes that hold and release finish evenly, avoid shedding, and provide crisp edges. Consider these factors when selecting a brush:
- Brush type: natural bristles can absorb more finish and release unevenly with polyurethane; synthetic filaments tend to perform more consistently with water- and oil-based products.
- Brush size: for large surfaces, start with wider brushes (3–5 inches). For trim and tight corners, smaller angles (1–2 inches) offer control.
- Edge control: angled sash brushes excel at cutting-in along baseboards, window frames, and corners.
- Durability: look for packs with secure bristle bonding and reinforced ferrules to reduce bristle loss during use.
- Finish type compatibility: verify that the brush handles polyurethane well, whether water-based or oil-based.
Practical tips
- Keep brushes clean between coats to maintain smooth application and extend brush life.
- Test on scrap wood to gauge brush performance before applying to the main project.
- Match brush size to project scale to minimize brush marks and ensure even coating.
