Wooster Brush 5222-1 1/2 Flat Sash Paint Brush

Product Description

The WOOSTER BRUSH 5222-1 1/2 is a 1.5-inch flat sash brush engineered for finish-coat work with enamels, varnishes, polyurethanes, and water-based coatings. It features Wooster exclusive CT (Chemically Tipped) polyester filaments that are thin, flexible, and soft, virtually eliminating brushmarks while maintaining a full-body feel. The filaments deliver strong bend recovery and responsive cutting action, making single-pass cuts clean and consistent. Painters, finish carpenters, and trade professionals who demand a smooth, level finish with minimal post-application correction will find this brush well matched to detailed trim and sash work.

The 5222-1 1/2 is suited for residential and light commercial finish applications. It performs well when applying enamels to metal surfaces, varnish or polyurethane to wood trim, doors, and cabinetry, and thinner water-based coatings on sash and detail work. The flat profile is designed for straight-line cutting and controlled coverage on narrow surfaces where precision matters. It is sold individually and is appropriate for use by painting contractors, finish tradespeople, and experienced DIYers working on high-visibility surfaces.

Key Features

• CT (Chemically Tipped) polyester filaments provide a thin, flexible tip that virtually eliminates brushmarks
• Strong bend recovery supports sharp, single-pass cuts on sash and trim
• Excellent leveling and smoothing with enamels, varnishes, polyurethanes, and water-based coatings
• Stainless steel ferrule resists corrosion and holds filaments securely

Compatibility

Designed as a general-purpose flat sash brush compatible with oil-based and water-based paints, varnishes, polyurethanes, and enamels applied to wood and metal surfaces.

Installation Notes

This brush is a hand-application tool, not a mechanically installed component. Before use, flex the filaments gently and remove any loose bristles. Clean thoroughly after each use with the appropriate solvent for the coating applied — mineral spirits for oil-based products, water for latex and water-based coatings. Store flat or hanging to preserve filament shape and extend service life.
