Polishing and grinding a concrete floor is a process that involves removing the top layer of the concrete surface to expose the aggregate and then smoothing and polishing the surface using a series of diamond polishing pads. Here is an overview of the typical process:
Surface preparation: The first step is to prepare the surface by cleaning and repairing any cracks or holes. The surface should be thoroughly cleaned and free of any dirt, dust, or debris.
Grinding: Once the surface is prepared, the grinding process begins. The contractor will use a heavy-duty grinder equipped with diamond grinding pads to remove the top layer of the concrete surface and expose the aggregate. The grinding process can take several passes, starting with a coarse grit pad and gradually moving to a finer grit pad.
Polishing: After the surface has been ground, the polishing process begins. The contractor will use a series of diamond polishing pads with increasingly finer grits to smooth and polish the surface. The final polishing pads will leave a high-gloss finish.
Densifying and Sealing: Once the polishing is complete, a densifying agent may be applied to the surface to harden and strengthen the concrete. The surface can then be sealed with a concrete sealer to protect it from stains, moisture, and UV damage. The sealer can be applied using a sprayer, roller, or brush and should be allowed to dry completely before foot traffic is allowed.
Maintenance: To keep the polished concrete floor looking fresh and new, regular maintenance is necessary. This may include sweeping, mopping, and occasional resealing to protect against wear and tear.
Overall, the process of polishing and grinding a concrete floor requires specialized equipment, skill, and expertise. A professional contractor with experience in concrete polishing and grinding can ensure a high-quality result that will last for many years.
