Black Exterior Limestone

Article Number: 597 | Rating: Unrated | Last Updated: Mon, Oct 8, 2007 at 12:00 AM

When laying exterior limestone the stones a)became lighter with atmosphere & b) contractor spilled a lot of cement onto slabs - I was told to use 'Cement Away' which I did. Now the stones are a very pale grey - Please tell me how I can get colour back to black?

Dear Sarah:

If the stone gets ot look black again when it's wet, then the application of a good-quality stone color enhancer like MB-6 will give you back the depth of color permanently. Well, "permanently" is a big word!... Let's say that probably you will have to apply it once a year or so. You will be able to tell when the need arises.

May I ask you now to please read and e-sign our Statement of Purpose at: http://www.marblecleaning.org/purpose.htm? J

Ciao and good luck,
