Start off with hand scraping the excess materials from the stone. then use and acid based cleaner. On this job you may need to use some Prosco Masonry cleaner. If you use this cleaner be sure to follow the directions for the proper mix.

Apply the cleaner and allow to work for 5 to 10 minutes then use a scrub brush and clean the area, several application may need to be applied.

Subject: [sccpartners] Concrete setting material on granite



We have been asked to remove and clean up some concrete or grout setting material on a rough granite floor where a large planter was removed.  Was wondering what you all might recommend to take this stuff off.  I was going to start with some stiff brushes on a floor machine and acid cleaner.  Because of the rough nature of the granite, I am tentatively assuming that the acid will not hurt the granite. Here are some pics.

Thanks, Baird
