We are in the process of tearing up our existing flooring to prep for acid stain. We have the usual carpet glue, a little tile mastic as well as a bit of linoleum mastic. We are renting a carbide grinder to remove the mastic,ect and then a stone grinder to smooth out the surface. In the kitchen, there appears to be some exposed aggregate, same at the entryway, where the tile was. Would it be possible to grind the kitchen to expose the rest of the aggregate and then stain it like that? I know the stones won't accept the stain, but the surrounding concrete will. If I could grind it to be uniform, I think it may look kinda cool. Same would apply to the entry way. Would the carbide grinder expose aggregate eventually? Any input would be greatly appreciated.
