I am working ona flagstone/slate combo floor in a 1930 era "falling waters" style residence. The floor has been neglected with different owners applying different types of cleaners and sealers and waxes over the years, as you might suspect. I have stripped off all of the sacrifial coatings on the floor revealing what I consider a poor -sloppy installation with signifiicant grout/mortar builup especially on the steps. It is not haze; it is what I consider to be "chiselable" for lack of a better word, deposits. The client has become driven to remove these deposits. I ahve used acid based grout haze/efflorescence removing cleaning agents with some results , but they are extremely slow. Does anyone have any suggestions which might help expedite the process? Should I try "chiselling" or perhaps a mechanically abrasive process?
Secondly I had intended to apply a color enhancing impregnator ,(Stonetech water based) and did so achieving poor results. Floor appearred blotchy ( not sealer white residue ) after 2 applications . "Blotchiness" would not buff out. I am now working on removing whatever is left of the impregnator and intending to go back to a topical sealer. Holding my breath though as I am concerned as to whether the topical will conceal everything.
