Hi, My dad and I are planning to install the entry floor with marble tile. My dad was a contruction worker a few years ago but he had not worked on installing the tile especially marble tile. So we really appreciate your help. Please take your time to answer some of our questions: 1) If the floor is a concrete cement with pretty even surface, do we need any backerboard? 2) Should we use mastic or mortar? 3) Can a typical $800 wet saw cut 3/4 inch thick marble easilly or we need a more powerful one? 4) Can the wet saw cut a curve? How hard is it to do it? Thank you so much for your time.

I'm working with 2" tiles in a sheet 12" x 12" and I've come to several light switches and plug-ins. Is the accepted procedure to cut strips from the individual tiles to fit around the outlets, or is there a way to cut L shapes for the corners? I work in wood and if I were using wood, that would be simple, but this tile stuff is not quite the same...... Thanks!
