What are the steps for polishing a concrete floor?
Georgiev: The steps for polishing concrete depend on what condition the concrete is in before you get started. If a floor is in great shape, I would start by grinding the floor with a 120 grit metal bond diamond tooling under a passive planetary machine. This will allow for proper surface preparation and evening out the floor. Rougher grits could be used before this if the floor is very uneven and blemished. You should vacuum thoroughly between each step. After 120 grit metal plates, you would switch to 50 grit resin pads, clean the floor again, switch to 100 grit resin, vacuum, switch to 200 grit resin and vacuum again. Once this process is completed, then you would apply a densifier to the floor with an air pump sprayer and a microfiber mop. Once the densifier is dry to the touch, then you continue on with the resin bond diamond tooling steps beginning with 400 grit resin pads, followed by 800 grit, 1,500 grit and 3,000 grit until the concrete floor has the desired clarity and shine.
