How is concrete polished?
Mechanical vs Topical Polishing
There are two methods of polishing concrete: Mechanical and Topical
Mechanical polishing uses specialized grinders that use progressively finer diamond impregnated bits that gradually close the pores of the concrete surface. The final product is a very hard surface that has a high gloss surface. Dyes, artwork, engraving can be included during this process.
Topical polishing may use grinders to rough up the surface but then a chemical coating is applied which adheres to the surface of the concrete. Examples of topical coatings would be: Clear coatings and colored coatings. Clear coatings allow the client to add dyes, artwork and engraving. Colored coatings limit the client to the color options available from the manufacturer.
Benefits of Mechanically Polished Concrete
There are four significant reasons to consider a mechanical polished concrete floor
Mechanical polished concrete floors are striking. Whether dyed or left uncolored each polished concrete floor is unique and beautiful. Even old concrete floors shimmer and are extremely attractive when mechanically polished. Mechanical polishing accentuates the existing character of any concrete surface even when there are existing imperfections. Mechanical polished concrete floors produce the highest luster surfaces available without any environmentally harmful chemicals. They are beautiful and “green”.
Lower Lifetime Cost
Mechanical polished concrete are very durable and easy to maintain. They excel in high traffic areas such as schools, hallways, corridors hold up better and last longer with a mechanical polished concrete floors. Cleaning a mechanical polished concrete floor is extremely easy. Just mop with clean water or a neutral PH cleaner on a regular basis. If the surface starts to dull after years of wear a burnishing machine with a 1500 grit pad will bring the shine back to life. This is a very inexpensive process if needed. Manufactures have been using mechanical polished floors for years because of it durability, longevity and ease of maintenance.
Ambient Lighting Reflectivity
A highly mechanically polished concrete surface is extremely light reflective. This is very helpful in office buildings, hotels, restaurants, manufacturing and other public facilities that want to project a bright, clean, professional image. This increases visibility and reduces the amount of lighting needed in most buildings.
Mechanical polished concrete surfaces contain no Volatile Organic Compounds (VOCs) which makes it an environmentally friendly surface. There are no coatings applied, such as epoxies, urethanes, or waxes.
