Polished Concrete is a flooring solution which is both economical, ecological and durable. It is achieved by a 7-step process using diamond tools to grind and hone a concrete slab to a high gloss finish. Polishing your concrete floor will transform it into a beautiful, functional and low maintenance surface without the use of topical coatings! The acid staining process is similar to polished concrete. The floor is ground with aggressive diamonds to remove all latent defects and substances that might interfere with the acid stain reaction.
