I used 511 impregnator on my Black Galaxy countertop that is 6 years old. I followed the instructions 3 times, and my countertops still look streaky. HELP!!!

 

Dear Barbara:

And why on earth did you ever even think of sealing Black Galaxy???... Nothing goes inside that stone!

And now for over 6 years you had to live with a streaky countertop because of the useless impregnator that you tried to apply to it!

What to do?

That stuff is really, really nasty to remove, unfortunately. Chemically, you may consider using a potent paint stripper based on Methylene chloride. Terrible stuff! If you decide to go that way, let me know in advance so that I can move out of the country for a couple of weeks! If not, your only option is to have a bona-fide stone restoration contractor coming over and remove the residue of the impregnator with a polishing powder for marble designed to do “dry-polishing”. That would be quick and odorless.

After that, don't you ever think about applying any other impregnator to that stone! It's the same stone that I have in my super-busy kitchen for over 11 years and never had a problem with it. Of course I never “sealed” it (I know what I'm doing, thank you very much), and all my wife and I have been using to take care of it after our heavy-duty cooking sessions is MB-5 on a daily basis and a little tiny squirt of MB-13 once a week or so.

Easy enough for you?... J
