Wooster Brush 4181-1-1/2 Angle Sash Paintbrush 1.5 in

Product Description

The WOOSTER BRUSH 4181-1-1/2 is a 1.5-inch thin angle sash paintbrush from the Ultra/Pro Willow line, designed for clean, controlled cuts on trim, sash, and detail work. The brush uses a firm nylon/polyester filament blend that holds a consistent edge across both water-based and oil-based coatings. A square rust-resistant steel ferrule locks the filament in place and prevents splaying during extended use. The treated maple handle is tapered for a balanced grip during overhead or close-detail application. Painters, finish carpenters, and maintenance pros rely on this brush for tight lines and consistent coverage on interior and exterior surfaces.

This brush is suited for residential and light commercial painting tasks where precision matters: window sash, door trim, baseboard, cabinetry edges, and similar narrow or angular surfaces. The thin profile lets the bristles access corners and frames without overloading adjacent surfaces with paint. The firm formulation performs well with latex, acrylic, alkyd, and enamel coatings. It ships in a package quantity of six, making it practical for job-site stocking or crew supply.

Installation Notes

Before use, work the bristles gently by hand to remove any loose filaments. For water-based coatings, pre-wet the brush with water and remove excess moisture before loading with paint. For oil-based coatings, pre-condition with the appropriate solvent. Clean thoroughly after each use to preserve bristle shape and extend brush life.
