Abstract
A masking material comprises an elongate strip at least partially coated with a layer of a pressure-sensitive adhesive, die strip having a curved surface which is convex when the strip is viewed in cross-section and is positioned such that when the strip is adhered to a substrate by the layer of pressure-sensitive adhesive a portion of the curved surface overhangs the substrate. The masking material comprises a removable edge portion comprising said portion of the curved surface detachably secured to a remainder of the strip and which may be removed to expose a second curved surface on the remainder of the strip which is convex when viewed in cross-section and which is positioned to overhang the substrate. The removable portion and remainder of the strip have different dimensions. Methods for making such masking material are also described.
