I am thinking of putting granite tile on the countertop in my kitchen. I really don't want to remove the existing countertop. Would it be acceptable to lay cement backerboard over the exisiting formica or could I just rough up the surface and lay the granite over the formica? Also, I want a slittle grout lines as possible. What is the minimum width for the grout? Is there a trick to applying grout to granite?
Thanks
