Hi Bill, How does one find out if a stone is "extremely porous" - e.g. I have a few different stone floorings recently installed but not yet grouted (Benjamin Gray limestone, Lagos Azul limestone, and Gray Sandstone) - what do I need to do to figure out whether to upgrade to Porous Plus, or just stick with Impregnator? (Or one of the other recommended sealers.) Thanks, Becky

I am having marble installed in my kitchen soon and my fabricator will seal it with Miracle 511 Porous Plus. They said that this sealer will simultaneously remove old sealer as it puts down new and penatrates into the stone - so that there is no "tacky" sealer buildup. (Not sure if that's what the OP read about regarding cleaning while sealing.) Anyway, according to them, you only need to seal once every five years or so. Does anyone in the know have comments about this? I want to make sure the counters are sealed properly to minimalize staining. Thanks!

I've had great success with aqua mix's sealers choice gold and miracle' 511. These are available almost everywhere (box stores) and are not crazy expensive. I currently have 511 on my French limestone counters in my main residence. No stains in 7 years with only the application upon install. Dry Treat is voodoo in a bottle ,but is $$$ and only available at specialty shops. DuPont's offerings have a solid rep with some of the best tile guys in the industry that I know.

Thank you so much Babushka cat! I read all about your counters when I was contemplating my own. There don't seem to be a lot of us creamo delicato owners out there. (I also have an orange & white cat...although I don't think mine would fit in a bowl-he's almost 20lbs!). Was your 511 applied after any other sealer or was that the only product you've used? Any other experiences? Maybe Bill V is still around??
