This is a concrete floor done in Buena Park, CA by Albuquerque Polished Concrete Company. This is a high gloss polished concrete floor with heavily exposed aggregate. We used the Husqvarna PG820 planetary grinding machine and started with 30 grit metal bond diamond tooling to expose the aggregate in the floor. Wet grinding was used to produce the floor and a sodium silicate densifier/hardener was used to assist in the concrete polishing process. The floor was polished to a 3000 grit finish using resin bond diamond tooling and sealed with a lithium densifier based polished concrete sealer. The floor was then burnished with a hogs hair pad and a high speed propane burnisher. Please go to our website for more info. Enjoy!
