Grinding & Polishing

 

Polished concrete is a multi-step process where a concrete floor is mechanically ground, honed and polished with bonded abrasives in order to cut a concrete floor's surface. It is then refined with each cut in order to achieve a specified level of appearance.

This process also includes the use of a penetrant chemical known as a hardener. The concrete densifier/hardener penetrates into the concrete and creates a chemical reaction to help harden and dust-proof the surface.

During concrete polishing, the surface is processed through a series of steps (in general a minimum of 4 grinding steps of processing is considered polished concrete) utilizing progressively finer grinding tools. The grinding tools are progressive grits of industrial diamonds in a bonded material such as metal/hybrid/resin often referred to as diamond polishing pads.

 

Polished concrete is a "green" flooring system and LEED approved.[1] Concrete is not considered polished before 1600 grit, and it is normally finished to either the 1600, or 3000+ grit level.

There are four levels of polishing and levels of exposure:

Polishing:

Level 1 - Flat / Ground

Level 2 - Satin / Honed

Level 3 - Semi / Polished

Level 4 - Highly polished

Exposure:

- Light sand / cream finish

- Salt and pepper finish

- Medium aggregate finish

- Large aggregate finish
