I have this floor in the entry foyer of my home. You can see there's a small portion (near the top of the photo) that is shiny, but most of it is dull and scuffed (like in the rest of the photo). How can I give it a mirror shine again?
Here is another angle of the same portion of floor as in the first picture.
I have never shined a floor before. This floor has looked like this since I bought it. I'm not even sure what to call this tile. I have some different tile in my kitchen and bathrooms, what I understand is ceramic tile, that is not meant to shine. Is this porcelain tile?
I thought I might rent a buffer from Home Depot like I saw maintenance workers use in my schools and office buildings, but then I saw this video trying to explain the difference between buffers and burnishers. I don't know which I need. I don't know what stripping the floor means. Do I need to do that?
That video says not to use buff spray, but to use a "restorer". When I search Home Depot for floor restorers, they're all for wood floors. So now I'm really lost.
I want a shiny floor. How do I do it?
