utor 0 Report post Posted April 19, 2014 Hi!I wish to ask some third party opinion.I got my marble flooring (white cored) laid fairly recently (about a month) and realised that there tiles with spots of grey/totally greyish in color. I checked with the marble supplier and was told that it is due to sealant being applied and that marble, being a natural stone have different absorbance level and that given time (up to 6 mths!) The sealant shld ne totally absorbed and it shld be the same color tone.I cant find any information to corroborate with what the marble supplier said so I am wondering if anyone has similar or knows any similar cases!Thanks in advance!
