Grinding Concrete Floor Experience

[pokop]

I'm planning to paint my new shop concrete floor. There are some surface problems that concrete grinding should address. I did some research on the net and know that a local company named Sunbelt Rental rents concrete grinding equipment. If you have done this to your shop floor I would like to hear from you. Good, bad experience? Hints or suggestions. Any and all comments on the process floor grinder Los Angeles. The surface finish of my concrete has some waves and areas where the surface is not very smooth. I thought the surface finish should have been better but now I need to deal with what is there. I think the grinding process is the best solution or is there something else I should look into? Thank you.
