GRINDING

What it is

Grinding is a treatment executed with machines rotating around a vertical axis. These machines can be single-plate or crown wheel (with more counter-rotating plates).

Different kind of tools can be mounted on the plates thanks to resinoid metallic binders of various types (according to the hardness of the surface to be treated) and grains (according to the desired finishing degree).

Grinding can be executed as a dry or wet process according to the surface to be treated and to the building site’s needs.

The possibility of obtaining an even and smooth surface makes grinding ideal for removing asperities/irregularities in the floorings and for creating remarkable aesthetic effects.

Grinding machines are pre-set for use with suitable intake systems; at the end of the process, it is still necessary to clean the surfaces through brushing and/or intake.

When and why

Grinding is a form of finishing in its own right, but also an important step in cleaning prior to the application of low-thickness paints and coatings. Grinding is performed to remove cement slurry, glues and paints from the substrate and grind stone surfaces. Asphalt grinding has recently become popular, it is executed with coloured inert to be brought in the surface.

Applications

Civil, industrial, naval, road sector.

As a finishing treatment, grinding gives the best results in the execution of cement floors, a very appreciated choice for renovations in industrial archaeology.

On vertical or irregular surfaces, like for example the walls a swimming pool, grinding is the preliminary step before waterproofing coating.

In the civil sector grinding represents the ideal bond, more lasting and regular, in the laying of resin floors.
