The OX Speedskim Semi-flexible plastic Plaster's rule features a tough aluminium handle and lightweight but durable plastic blade and is part of the new and revolutionary tool system designed to increase meterage output and enhance quality of finish. Superb for ruling off, flattening, and finishing all gypsum-based plasters (both hand and spray applied), traditional sand & cement renders and insulated rendering systems, it also comes complete with an integral blade guard. One of Speedskim's major benefits is the reduction in harmful effects of fatigue & RSI.
