Wooster Brush Company 3972-2 2" paint brush

2-inch flat sash paint brush

The Wooster Brush Company 3972-2 is a 2-inch flat sash brush with gold-coloured polyester bristles and a plastic beavertail handle. Firm bristle stiffness and a 9/16-inch thickness hold plenty of material for smooth, even coverage. It is designed for use with all oil-based and water-based paints and coatings. Suitable for medium and smooth surfaces including wood, drywall, metal, brick and concrete.

Trim painters and detail work

This brush suits decorators cutting in windows, doors and trim where a 2-inch width offers control without excessive reach. The firm polyester filament keeps its shape with heavy-bodied coatings. It is not for broad wall rolling or large ceiling expanses where wider tools cover ground faster. Buyers needing a softer tip for fine varnish or a wider head for open areas should look at alternative brush styles.

Surface prep and paint compatibility

Confirm the surface is clean, dry and free of loose material before brushing. The synthetic filament works with both oil and water bases, so match the brush to the coating you have selected. The plastic beavertail handle fits a standard hand grip; check that the 2 7/16-inch bristle length reaches the detail depth you require. No special solvents or conditioning are needed beyond normal brush cleaning.
