This pack of 10 abrasive mesh sanding sheets are a superb all round product for all trades and applications around the house. Their waterproof open construction makes them extremely good for sanding softer surfaces such as plaster which rapidly clogs normal sandpapers. The hardness of the silicone carbide abrasive coating, makes them good for sanding paintwork, varnishes, woods and metals. This size fits all half sheet sanders, with a clamp system to hold the sheet in place. The sheet is reversible, so you get twice as much use out of the sheet as normal abrasives, and it is flexible so you can easily sand contours, and knock it clean or wash it when it gets dusty.
