The Osmo Flat Brush is ideal for applying the range of Osmo wood oils. Suitable for DIY and professional use, it has a flat, straight edge construction, perfect for corners and edging. With an ergonomic wooden handle for comfort and durability, this brush also has a sturdy metal bristle brace reducing bristle loss during application. Bristles are made from a high quality synthetic mix for a perfect finish every time.\nFor best results simply dip your Osmo Flat Brush into the oil or other product you are using, being careful not to overfill it, then brush evenly along the wood grain. Any surplus should be removed immediately with a microfibre cloth. Apply second coat of oil with the Osmo Oil Finish Application Fleece and remove excess.\nAvailable in four sizes, 25mm, 50mm, 60mm and 80mm.
