Wooster Brush 5220-3 Flat Sash Paint Brush 3 Inches

Product Description

The WOOSTER BRUSH 5220-3 is a 3-inch flat sash paint brush designed for precision trim and detail work. It features a white and silver chisel-trim polyester blend engineered for a very soft formulation that delivers a smooth feather stroke finish. The brushed steel ferrule resists rust, and the birch hardwood handle provides a firm, balanced grip during extended use. This brush suits professional painters and finishing tradespeople who need consistent cut-in performance on sash windows, door casings, and trim detail work.

This flat sash brush is suited for residential and light commercial painting applications. It performs well on sash windows, door frames, baseboards, and other fine trim surfaces where a controlled, smooth coat is required. The chisel-trim polyester filament holds and releases paint evenly, making it appropriate for water-based and compatible finish coatings. Sold in a package of 6 units, making it practical for stocking a job site or service van.

Installation Notes

When applying water-based coatings, clean the brush promptly after use to preserve filament integrity. Store brushes hanging or flat with filaments protected to maintain the chisel-trim shape between uses.
