We recently put down an alternating pattern of white thassos Marble (http://www.lightemprador.com) and (http://maplered.com) "absolute black" Granite (http://tanbrown.org) in our foyer. While attempting to grout with black grout we had some staining and (http://maplered.com) void fill. We immediately stopped the grouting process. We have successfully removed the marks from the Marble (http://www.lightemprador.com) with an intensive cleaner. Before we begin to grout again can you offer any suggestions for filling the voids with a synthetic resin. A trade name for the product would be most appreciated.
