The Differences Between Mechanically and Chemically

Proper polishing pays. The best floors have been mechanically processed and the gloss is generated from the concrete’s flat surface profile rather than created by artificial means. Properly polished floors allow owners to use lower-cost maintenance options to keep the floors looking good with a high-gloss finish.
