These people want a better polished finish. This was 3 feet under water in the Brisbane floods 9 months ago, led to some micro spalling. Need to bring it up somehow. Has sanded grout (as usual) so a big grind is not an option. Would like to fill the pores somehow. Does anyone know the composition of this stone, it is very different, not dense at all. Something like the VMC product V3 maybe?
