The 80 x 230 mm size of this Mirka Hand Sanding Block makes it perfect for wall sanding because it reduces the risk of tilting during use. There’s an easy to access 20mm hose connection and an adjustable suction valve to allow for optimised dust extraction and air flow and help the tool move easily over the surface. The plate features 55 holes precisely placed to ensure effective dust removal and the grip fastening system means there’s no time consuming clamps to deal with. There’s even an ergonomic, soft-feel, two handed grip and the eye catching design in bright yellow mean it’s always easy to find!
