Will it work for grave stone made of granite? Want to clean and polish it.

it should, if the surface is rough it may soak up quite a bit of the product initially though. I'd bring a couple heavy duty rags to apply it evenly.

Can this me used on an unsealed limestone hearth?

Yes, but this will not really seal your stonework. Also note this cleaner is no more effective than basic soap and water cleaning. If it is new limestone, I recommend getting it professionally sealed first or at least using a basic sealer like Black Diamond Nex-Gen Natural Stone Penetrating Sealer and then using a stonework polish if you want some luster.

Can this be used on floors?

Hi Patricia, It absolutely can be used on floors. I use this on my polished travertine floors all the time.

do you need a separate sealer or will this be able to seal just on its own?

Use the Black Diamond sealer initially and then you can use this product to clean and seal. It is a fabulous product and I use it daily to keep the counter looking good as new (our granite is in our bathroom and between hairspray and cosmetics, dirt can build up fast.). We used the sealer initially four years ago and counter looks good as new today.
