Buying Guide: Key Considerations For Polyurethane Finishes
- Brush type: Choose flat brushes for broad coverage and angled brushes for tight corners and cutting-in around trim.
- Bristle material: Natural bristles excel with oil-based poly; synthetic filaments work well with water-based poly and cleanup is easier.
- Filament durability: Look for brushes with secure ferrules and adhesive bonding to prevent bristle loss.
- Size selection: A mix of 1–2.5 inch brushes covers most interior polyurethane tasks; larger heads speed up flat surfaces, smaller heads handle edges.
- Maintenance: Clean immediately after use; store bristles in their natural shape to maintain performance over time.
