Dear Maurizio, Our stone mason has just started laying our marble. Each marble slab is about 4 ft by 3 ft. At this early stage of marble laying I am a bit bothered by the fact that adjacent slabs are often misaligned by perhaps upto 2 millimeters. The stone mason claims that the marble slabs naturally have slightly uneven thicknesses, which causes the misalignment. He assured me that the final grinding/polishing process will create a nice smooth planar surface with no "bumps." Does that sound right to you? Is it true that early in the marble laying process slight undulations arise, which are then evened out during the polishing stage? Best regards, Arvind

 

Dear Arvind:

Where do you live, if I may ask?

Your query is quite interesting and somehow stirs memories for me; and the reason why I asked where you live is because your message seems to indicate that you're going to have a “grind-in-place” installation of a marble floor in your home; a clearly superior technique of stone floor installation that never found many takers in the USA, and that therefore is to be considered quite unusual. Your mention of mm instead of fraction of inches makes me guess that you're from some European country – Eastern Europe, maybe. (In my days, back in Italy I installed a lil over 400 marble floors in that way.)

Now, to answer your question, if the grinding, and polishing is part of the installation (as it always should), then your installer is 100% right. Don't worry: those 2mm “lips” will be easily cut down and disappear with no problem.

 

May I ask you now to please read and e-sign our Statement of Purpose at: http://www.marblecleaning.org/purpose.htm?

Ciao and good luck,
