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 polished porous granite, would a solvent based sealer be more
efficient / effective than water based sealer ?
(For kitchen counter top )
Kindly respond.
Thank You.
