Diamond Polishing is a process that turns a structural foundational concrete slab into a functional, high
performance and easy to clean floor. The concrete surface is sealed mechanically via diamond polishing,
eliminating dusting, preventing chemical or dirt intrusion and making the floor easy to clean and maintain.
Diamond Polishing is a relatively new practice (1997) using natural stone polishing techniques from
Europe to grind and polish a concrete slab floor (new or existing) to a high sheen, similar to marble or
granite polishing. This process also involves hardening the concrete surface using silicates or related
compounds. Large, heavy, state-of-the-art walk-behind machines with rotating diamond
abrasive heads remove the surface layer of the concrete and achieve a fine polish. Progressively finer
diamondabrasives are used to refine and polish the concrete surface. we perform all of our grinding and
polishing dry,
that is, without the use of water. We use sophisticated dust collection systems that collect virtually all
dust during the polishing process.
During the polishing process, a sodium, lithium, or potassium silicate is applied to the floor to densify,
or harden, the concrete. The solution is absorbed into the concrete surface filling the pores. Chemically,
the silicate reacts with the calcium hydroxide molecules which occur naturally in concrete to produce
calcium silicate hydrate. After the silicate infuses into the concrete, it crystallizes in place. Then the
polishing continues.
The end result is a chemically hardened concrete surface that can be dyed or not, that has been
mechanically refined and sealed using diamond abrasives. There is no topical chemical sealer or wax
of any kind. Because there is no sealer or wax, the polished concrete never needs to be resealed or
waxed. There is nothing to bubble, turn white, flake off, wear off or turn yellow.
