Works great to grind polyurea joint filler
We use this discs when filling control joints in warehouses with polyurea joint filler compounds. This disc is aggressive enough to remove the overfilled material, but does not leave significant scratching on the concrete. This is great to use when we are only filling joints and not grinding the entire concrete slab. It is a great option for polished concrete and coating professionals/DIY'ers.
