4" Biber Paint Brush (100mm) - Professional Straight Brush (Oil/Acrylic/Alkyd)

Meet the workhorse. The Biber 4" (100mm) straight flat paint brush is the widest of the family, and it's built for the jobs that separate the dabblers from the doers — full walls, long fence runs, thirsty decks, sweeping undercoats and any large flat surface begging for fresh colour. When the job is measured in metres rather than centimetres, this is the brush you want in your grip.

Its broad head of black synthetic bristles drinks up water-based and oil-based paints alike, then releases them in smooth, even sweeps that eat up surface area with every stroke. Fewer dips, fewer passes, faster knock-off time. The glossy red handle with gold tip and BIBER branding is contoured to spread the load across your hand, so those long fence sessions stay comfortable from the first paling to the last. A polished silver ferrule shrugs off rust and keeps the bristles firmly seated, and the hanging hole in the handle means this brush hangs up to dry properly, ready for the next weekend mission.
