This article is about polishing concrete floor surfaces in ways that take longer.

Polishing concrete

Here is a step-by-step description of the process of polishing the concrete. If you follow the method correctly, you can achieve a shiny polish look that will last for a long time.

Cleaning and repairing the surface:

You need to clean the entire surface with soapy water. Also, use a brush to thoroughly scrub the concrete. Make sure you are using clean water. If the concrete has stubborn stains, you can also use hydrogen peroxide, ammonia, or TSP (trisodium phosphate). However, you should not mix the two chemicals.

You should also examine the concrete for damage and cracks. You can use marker paint to address them separately. For small cracks (0.64 cm), you can buy concrete crack fillers. You can apply it with a cartridge gun. If the concrete has wide cracks, choose vinyl crack patch material. Fill the crack with the patch material and smooth it on the surface with a trowel.

Smoothing the surface with the sander:

Rent a mill and look for a set of concrete grinding wheels. The discs should vary between 40 and 3000 grit. Make sure that the grinding wheels are metal-bonded diamond wheels. Put on protective gear and sand the surface in semi-circular motions with a 40 or 80 grit disc.However, if there are stains in the concrete that you couldn't wash off, choose a 40 grit disc, otherwise an 80 grit disc Grits. Start at one corner of the surface and work slowly.

Repeat the sanding process with 150, 200 and 400 grit discs. Make sure to spray on a compactor with 80, 200 or 400 grit after the sanding pass. For example, for soft concrete – use it after the 80 grit pass, while for medium-hard concrete use it after the 200 and 400 grit pass. You should do a final pass with a 3000 grit disc.

While you can skip 3000 grit passes, it gives concrete a shinier touch. You should vacuum dust and debris from the concrete surface before proceeding to the next step.

Polishing and sealing the surface:

Attach a polishing pad to the grinder and run it over all of the concrete. Now apply a thin layer of concrete sealer with a roller. It protects the concrete from stains and grease. However, make sure that you only apply concrete sealer in dry conditions. Wait 2-4 hours and apply a second coat of sealant. Finally, polish the surface again for a shiny look that will last for a long time.
