Honed and sealed concrete is best suited to outdoor areas, paths, driveways and pool surrounds where a non slip finish is required. When honing and sealing concrete for exterior use, we grind the concrete to 60 Grit, and we grind to 120 Grit for interior finishes. This is different to the polished concrete finish as that requires grinding to the many thousands of Grit. The way the floor is sealed at the end of the process is also different.
