I have a 12' x 12' concrete floor that was poured a bag at a time and has about a 2" high spot. The floor was worked too much and is far from smooth. What is the best and easiest way to level this floor?

thanks

Hi, never quite finished! Have we met before? Because it seems like we might be related as I can really relate to your name!

I am going to give an answer to your question a try since I like to do a lot of handyman type stuff myself, but what you are asking is probably out of my league and someone else may come up with a better answer.

I would suggest renting, if they are rentable, and trying some sort of industrial grinder like what you would find on the following page.

Angle Grinder, Surface Grinder and Straight Grinder at TOOLFETCH

Depending on how large the problem area is... the best solution (in my opinion) would be to cut out the high spot and re-pour new concrete.

There Is A Grinder That You Can Use To Smooth This Out, My Advise To You Is , If Possible Do What Is Called A Cold Pour, Basically You Resuface The Concrete With A 2" Slab. I Say 2" Just To Keep It From Cracking
You Can Get A Different Type On Concrete That You Can Pour A lot Thinner, But In Your Case If You Can Go Up Another 2" That Be The Way To Go

2" is a lot to try to grind and a cold pour needs to be 4" thick if you want 2" on the high spot. If you can take a 4" elevation change give it a try but how much do you think a new 12x12 pour will cost? Sometimes things are so screwed up you got to throw it out.

Where is the "problem" floor located in your house (garage, kitchen, bath, etc.)? I have a friend that has a concrete floor in his garage, that was in pretty bad shape. He cut out the real bad areas (and replaced them), patched the cracked section(s) and installed a very common brand/color/design of peel-and-stick vinyl floor tiles over the whole floor. Looks good, easy to repair/replace damaged or stained tiles and didn't cost very much. It was important to smooth the existing slab as much as possible though. Vinyl tiles will "telegraph" any texture or surface underneath it to the surface of the tile.
