This slim 1-inch brush is ideal for painting wooden trim such as skirting boards, door architraves, stair banisters, window sills, and window frames with oil-based paints like Gloss, Eggshell, and Satin. For best results, rub the brush with a clean hand before use to remove any dust particles and do not wet. Our Ultimate paint brushes are made to last. After painting, clean the brush with a specialised cleaner like white spirit. Refer to the paint tin for further guidance. *Bristle loss may occur if left to soak or in a damp area.
