sia Abrasives foam is long lasting, giving you multiple uses. sia Abrasives has developed a color coding system that is easy to understand and allows you to never mix up your sanding grits again. Each color represents a grit range/grade, this block is orange, indicating a medium grade. This block features an aluminum oxide grit coating on all four sides and edges, which allows it to adapt seamlessly to any edges and object profiles. The siasponge is easy to clean and also offers low clogging from sanding dust because of it's more flexible binder and soft carrier material, which removes sanding dust continuously, resulting in a longer life.
