refinishing blotchy concrete
The house I just moved into has a lot of white spots all over the concrete. I want to stain the whole slab to get it looking fresh and nice. I had a couple contractors come out to help me resolve the issue.
One of them said a stain would work no problem, get it covered right up and looking nice.
The other said, no way that even after staining after a while its still going to continue to bleed through. Probably forever, because the concrete wasn't laid properly. He said the best bet is an epoxy with a nice sealant. Even then there is no guarantee, but it has a better chance of working.
Who is correct? Does anyone have any other advice on what I can do?

I'd work at removing the old sealant and then resealing. I think xylene dissolves most of those type of sealers. Fresher minds should be along later to confirm ....... or set us both straight

so doing any kind of stain or paint on it is a bad idea? Is all the white the efflorescence that is trapped under the sealant? I'm guessing that because of the way it was mixed that I will be getting so much more efflorescence that it will just come back if I power wash and re-seal?
