Straighforward sanding processes are crucial in preventing mistakes during surface treatment. To help ensure greater quality control, Sia abrasives has developed a uniform color-coding system that is simple, logical and easy to understand. Each foam color represents a specific grit range or grade.

Additionally, siasponge soft foam abrasives are SOLVENT FREE, which is great for the environment. Maximum process reliability plus environmental responsibility – your key to a perfect surface.
