The abrasive occupies a central place in the world of sanding and finishing. Often unknown to the general public, it is the essential tool for artisans, industrialists, and seasoned DIYers. Used for cutting, polishing, or smoothing, it transforms and perfects surfaces with unparalleled precision. Far from being limited to sandpaper found in hardware stores, abrasives come in various forms, tailored to each material and use. Invisible yet omnipresent, it contributes to the quality of finished products, whether they are furniture, automotive bodies, or delicate jewelry.
The Centuries-Old Use of Abrasives
To understand the place of abrasives today, we must look back at their millennia-old history. Abrasives have evolved over time, from simple stone tools to high-tech materials.
