Hello again,

It now occurs to me to wonder about another aspect of this floor job. We're
going to lay the tiles over existing 1x1 sq ft vinyl tile. Installer says
this is fine as long as the tiles are firmly set and we've chipped away some
of the loose pieces around the border and used some floor leveler to build
up the slab to a height that's flush with the vinyl tile. He did go around
and pretty carefully inspect the floor for suspect tiles. Seemed to know
what he was looking for.

I've researched this a bit and didn't find any big red flags regarding
laying porcelain tile over vinyl. Basically just the same concerns that the
installer has, to make sure that the vinyl is firmly set.

Any other gotcha's regarding this I should be aware of? Is a special mortar
required? Any special surface prep of the existing vinyl needed? Again I
haven't seen anything jumping out of google searchs regarding this but if
someone has any info I'd appreciate it. Really like to do this right the
first time.

thanks for comments
