Lap mops are highly-flexible non-woven mops, ideal for satin finishing and graining of complex shapes. The mops consist of layers of heavy-duty woven fleece material, stapled together using leather washers and heavy-duty staples. A hole in the centre of the leather washers enables the mops to be used on machines fitted with a tapered spindle. Available in grades from very fine to coarse depending on the abrasiveness of the grit impregnation. Each section or layer is approximately 8mm thick.
