Aluminium oxide with ceramic coating. For sanding wood and stone. For wet and dry sanding, approx. 98 x 69 x 26 mm.
The sanding sponges are comfortable to handle. They are coated with abrasive on four sides. The special ceramic coating of the aluminium oxide abrasive ensures greater stability and longer durability of the abrasive grain. The ceramic coating also ensures that the abrasive does not clog up with dust as quickly during dry sanding. When sanding stone, they are recommended for wet sanding and then have a longer service life.
The specified grits of the sanding sponges roughly correspond to the higher grit of sandpaper:
Grain 36 corresponds to 60
Grain 60 corresponds to 120
Grain 100 corresponds to 240
Grain 150 corresponds to 400
Grain 220 corresponds to 600
Aluminium oxide (corundum) abrasives are very suitable for sanding wood and soft stone (alabaster, soapstone and the soft varieties of serpentine, limestone and marble) as well as for sanding metal. This has to do with the grain type: The abrasive grain of aluminium oxide is hard and blocky, slightly less hard compared to silicon carbide, but tougher. Silicon carbide abrasives are very sharp-edged, but more brittle, and the abrasive grain behaves differently during grinding. Silicon carbide is better suited to marble, harder stone and very hard wood.
A ceramic coating ensures greater stability and a longer service life of the abrasive. A stearate coating changes the spaces between the abrasive grains and ensures that the abrasive does not clog up with sanding dust as quickly.
