Four-sided sanding sponges – various grits

This four-sided sanding sponge (68 x 100 x 26 mm) is perfect for sanding terrazzo and GlassRoxx. With both techniques you cast colourful pieces into Jesmonite: terrazzo chips or GlassRoxx glass pieces. Sanding away the top layer of Jesmonite reveals the granules and colours beautifully. It is also an ideal choice for finishing other cured Jesmonite castings.

The sanding sponge sits firmly in the hand and its four abrasive sides easily reach edges, corners and rounded shapes. Available in three grits:

• P100 (coarse): remove casting edges and sand away the top layer of Jesmonite until the terrazzo chips or GlassRoxx appear
• P150 (medium): smooth out the scratches left by the coarse grit
• P240 (fine): finish for a smooth surface
