Wooster Brush 4175-3 Flat Sash Brush 3 Inches

Product Description

The WOOSTER BRUSH 4175-3 is a 3-inch flat sash brush engineered for precision coating work across a wide range of surfaces. Built under the Ultra/Pro Mink Firm line, it features a nylon/polyester bristle formulation rated for firm performance, delivering consistent control during application. The treated maple wood handle provides a stable, comfortable grip during extended use. A round, rust-resistant steel ferrule secures the bristle load and resists corrosion in wet coating environments. This brush is suited for trade painters, finish carpenters, and facilities maintenance crews who need reliable cut-in performance on trim, sash, and detail work.

The 4175-3 is designed for use with all coating types, including latex, oil-based, and waterborne formulations. Its flat sash profile makes it well suited for window sash, door frames, baseboards, and other trim applications where a clean, controlled stroke is required. The firm bristle formulation holds an edge well and releases paint evenly, making it practical for both residential repaint work and light commercial finishing tasks. Sold in a package quantity of 6 units, it is a practical stocking choice for painting contractors and supply houses.

Installation Notes

Applied by professional painters and finish trade workers. Before use, condition the bristles by flexing them gently and removing any loose filaments. For water-based coatings, pre-wet the bristles with water and shake out excess before loading with paint. Clean thoroughly with the appropriate solvent for the coating type immediately after use to preserve bristle integrity and extend brush service life.
