Our Products » Polished Concrete Floors "Grind and Seal" system V's "Grind and Polish" system
The Grind and Seal method is very common and widely used. However this system it is not a true "Polished Concreter Floor". The Grind and Seal method is when the concrete is ground back to achieve the desired stone exposure level. After the grinding process has been completed the concrete is sealed with a surface applied clear coat sealer such as an epoxy, acrylic or urethane. This system is generally more cost effective. However this system is more prone to scratching and damage caused by the hard concrete surface having no flexability under pressure.
The Grind and Polish method is created by grinding the concrete back to achieve the desired stone exposure levels (same as in the Grind and Seal method) After the grinding process the concrete is hardened with a densifier. This densifier reacts with the cement and increase the surface strenght of the concrete. The densified surface is then "Honed" or "Polished" to achieve the desired sheen level. The honed or polished concrete is then sealed with a penetrating sealer to protect it form stains and migration of water into the surface of the concrete. After sealing, the surface is often Burnished to remove any surface contamination. The Grind and Polish system is becoming more widely used and accepted as a superior product to that of the Grind and Seal system.
