The Polytech Sash Cutter Paint Brush is a premium precision brush for cutting in and detail work – window frames, skirting boards, architraves, doors and trims. Its tapered filaments give a sharp, straight line, and the long unpainted timber handle gives you control. Available in 50mm, 63mm and 75mm, and suits both water-based and oil-based paints.
Features
Synthetic blend – suits both water-based and oil-based paints.
Solid round and tapered filaments – hold more paint, flow smoothly and level out for a professional finish.
Heat-treated bristles – resist flaring and spring back to shape, use after use.
No bristle loss – stainless steel ferrule and pins, steel reinforcement and epoxy glue hold every bristle in place.
Unpainted timber handle – specially shaped for a comfortable, non-slip grip and better control.
Best for
Cutting in along ceilings, corners and edges
Window frames, skirting boards and architraves
Doors and trims
Sash cutter or oval cutter?
Both are precision brushes. The sash cutter is a great all-round cutting-in brush. The Polytech Oval Cutter, with its oval shape, gives even more precision on fine work like window frames and skirting boards.
Care
Clean your brush straight after use – warm soapy water for water-based paints, mineral turps for oil-based – then reshape the bristles and hang or lay flat to dry. Looked after like this, a Polytech brush will outlast many others.
