Proform Void Series sash brush with a PBT/PET synthetic filament block for cutting in clean lines with latex, acrylic, and waterborne paint. The angular trim and long sash handle let you guide the brush along trim, sash, and corners with one finger on the ferrule for control.

• Brush width: 3"
• 40% PET / 60% PBT blend filament - polyester blend stays stiff in water without going limp or losing its chisel
• Angular-cut, chiseled tip for cutting in to ceilings, casing, sash, and trim
• Sash-style natural wood handle for finger-on-ferrule control during detail work
• Tin-plated steel reinforced ferrule, all wooden plugs, epoxy-bound block
• For latex, acrylic, waterborne enamel, and water-based stain - the PBT/PET blend also handles oil-based finishes

Best use for 3": Wide cutting-in and broad trim - large door frames, fascia and soffit, exterior trim, and wide casing. Carries enough paint to cover long runs without reloading.

Tip - Filament direction: The synthetic block was designed primarily for water-based paint. Unlike natural China bristle, PBT/PET will not absorb water or droop, so it cuts a crisper line in latex than a natural-bristle brush.

Tip - Care: Rinse with warm soapy water for latex and acrylic, or mineral spirits for oil-based, until the water runs clear. Comb the bristles straight while damp and store in the original cardboard keeper to hold the chisel edge.
