Soft Italian Marbles /Polished Porous Granite.

Dear Sir,

A)  In soft Italian marbles (especially Satuario & Greek Thassous) There is
a lot of ferrous content
within. On installation, due to moisture vapour transmission, the ferrous
content apparently
turns into ferric oxide and appears on the top surface as a golden brown
stain (small, medium
or as pin head spots)

Poultice rarely works effectively for this problem

Is there a solution to this ?


B)  For ,  would a solvent based sealer be more
efficient / effective than water based sealer ?

      (For kitchen counter top )


Thank You.

Mehul  Jhaveri.
