Wives tales cause damage and expense.  Marble CAN look good all the time - with the appropriate maintenance.  Grout does NOT have to be stained - with the appropriate installation.  The lack of appropriate training at the Architects/Designers level contributes to higher cost of building maintenance and a reduction in green care.   This manual represents the basic education necessary to specify maintenance and restoration of interior stone and tile. This manual has been developed as a guide and workbook to aid the Architect/Designer in specifying stone and tile restoration and maintenance. If your an Architect or Desginer and you need info on stone...this is the manual for you.
