2cm granite: plywood underlayment or plexiglass?
I have always thought that plywood 5/8 ACX was to be used for 2cm granite plywood underlayment. I have recently learned that plexiglass can also be used. I had never heard of this method. Does anyone else know anything about the pros and cons of using plexiglass? I was told that the plexiglass come in thickness up to 2".
