Formulated with 100% DuPont™ Chinex® extra-firm filaments to maintain crisp painting edges and stiffness in hot, humid weather. Ideal for today's heavy-bodied latex paints, low-VOC coatings, and high-solid stains, releasing paint fast and washing clean in minutes.
Master heavy coatings and precise trim work with the Wooster® Chinex® FTP® 3" Flat Varnish Paint Brush (4413).
Engineered specifically for today’s fast-drying, thick-bodied paints and low-VOC formulations, the Wooster Chinex FTP (For Today's Paints) series provides exceptional stiffness and paint release. The 100% white DuPont Chinex synthetic bristles are modified for added firmness, allowing you to push heavy latex paints, acrylics, oil-based enamels, and stains onto textured or smooth surfaces with full control and minimal drag.
At 3 inches wide (76 mm), this flat varnish brush is versatile enough for broad wall sections, fascia, siding, doors, and wide trim. The unique mechanical property of Chinex filaments makes cleanup significantly easier than traditional synthetic bristles—dried paint washes off quickly to preserve tip shape and extend brush service life. Built with a stainless steel ferrule and a sealed natural hardwood handle for maximum balance and comfort.
