Grinding & Polishing


Blastrac diamond grinders and polishers use horizontally rotating disks to level, smooth or clean a concrete surface. A diamond tipped or other type of abrasive wheel is mounted on the grinder. The grinder may have single or multiple heads, typically up to 3. Planetary grinders are well suited for highly polished concrete. Grinders or polishers coupled with the appropriate vacuum offer a virtually dust-free and comfortable work environment.

Our grinders are perfect for:

  • removing coatings or adhesive residues
  • smoothing or flattening concrete slabs–including curled expansion joints
  • removing surface imperfections and contaminants

For decorative concrete applications, use the diamond grinding machines to polish concrete to a high shine or to restore old slabs for architectural finishes.

Depending on the type of abrasive wheel used on the grinder, it can be used to lightly prepare the surface, especially useful when applying thin coatings, or can quickly remove mastics, epoxies, urethane, paint and thick coatings. Special types of multi-headed grinders can be outfitted with carbide tipped slicers to quickly cut through heavy, built-up adhesives, elastomeric coatings, waterproof membranes and more.
