You should place a minimum of 50-mm of topping aggregate on the surface before applying any sealer or topping.

2. Grinding the surface:

The topping on top of the cement hardens the ground with a grinding machine. Based on the desired amount of smoothness, the correct number of cycles will depend on starting at around 16 grit and getting more acceptable from there.

Several different procedures can be used for this, including wet and dry polishing. It is straightforward to use the dry method, but it involves residual dust and resulting health risks.

3. Sealing the surface:

Sealant material is applied to the surface as a part of the grinding process. It can use to fill in cracks and holes created during the grinding process. Typically, the surface is further strengthened by adding a water-based chemical solution called densifier, which solidifies the surface further.

Adding water to the surface increases the density of the concrete, as well as protecting it before it polishes.

4. DIY Polishing the surface:

An artificial diamond shoe or pad of approximately 50-grit abrasive is used on the final stage of polishing. A stepwise increase in grit level is required, similar to the grinding process. Examples include 100, 200, 400, 800, 1500, and 3000 to attain the desired level of shine.

Grit and seal consist of removing existing treatments and membranes with a concrete grinder, smoothing out irregularities in the joints, and preparing the surface for any painting or floor covering. Getting a high gloss through fine abrasives will require a full polish by using a concrete polisher.

Dust-regulating vacuums are available on machines of all sizes or are available as separate units.
