CCA Carborundum Smoothing Flooring Stone - 24 Grit

Its primary use is to smooth, shape, and clean surfaces like screeds, concrete, brick, and stone by rubbing away high spots and imperfections, preparing them for floor coverings or achieving a uniform finish.

24 Grit refers to the coarseness of the abrasive material (silicon carbide). A lower grit number like 24 indicates a coarser abrasive, suitable for faster material removal and smoothing.

The perforations run through the entire stone and help prevent clogging by allowing dust and debris to pass through, thereby maintaining the stone's grinding efficiency even as it wears down.

This stone is specifically designed for abrasive materials like concrete, screed, brick, and stone. It is not intended for use on wood surfaces.

The handle is made of plastic, designed for grip and comfort during use.

You can clean the stone by brushing off dust and debris from its surface and perforations using a stiff brush. Ensure it is dry before storing.

If you are working on very hard concrete surfaces for an extended period, using a second stone can help maintain a better finish and prolong the effective life of each stone.

Ensure the surface being worked on is appropriate (concrete, screed, brick, stone). Clean the perforations and abrasive surface of the stone to remove any clogging. If working on very hard concrete, consider using a second stone for consistent performance.

This is more likely on extremely hard concrete surfaces. The stone's design still maintains grinding efficiency due to perforations. For prolonged use on very hard materials, consider purchasing an additional stone, as discounts may be available.

Ensure the handle is properly seated in the stone. If it remains loose, contact customer support for assistance.
