Description
The WOOSTER BRUSH 4413-3 is a 3-inch varnish brush built around 100% white DuPont Chinex filament, a synthetic bristle material engineered for superior durability and consistent stiffness control through the full length of a finishing job. The stainless steel ferrule resists corrosion and holds the filament bundle securely, while the sealed maple wood handle provides a stable grip during detailed trim and finish work. The Chinex FTP (Fuller Tip Profile) filament is exclusive to Wooster, offering a softer, fuller tip that promotes smooth paint release and reduces drag across wood, metal, and other finish-ready surfaces. This brush is sold in packages of 6 units.
The 4413-3 is suited for applying varnishes, urethanes, enamels, and oil-based finishes in residential and light commercial settings. Typical applications include cabinetry, trim, furniture, doors, and other surfaces that demand a smooth, streak-free film build. The Chinex filament cleans up readily with solvents or water depending on the coating system, making it a practical choice for professionals who cycle through multiple coats or product types in a single day.

Installation Notes
Painting and finishing contractors should condition the brush before first use by flexing the bristles and removing any loose filaments. Work in a clean, dust-controlled environment when applying clear finishes to avoid surface contamination. After use, clean thoroughly with the appropriate solvent for the coating system applied, then reshape the filament and store the brush flat or hanging to preserve tip geometry.
