I am sure this is a stupid question but can someone tell me why I
shouldn't
lay floor tiles straight on to cement rather than a tile adhesive? I need
to
raise the floor level by about 25mm in addition to the adhesive/cement and
tile so if I have to use adhesive what do I fill the remaining 25mm with?

Thanks in advance.

Bill,

If you could state the type of tiles that you are laying, then you should
get some specific help as each type requires a different fixing method.

(Here is a rough guide using the info that you gave). If it's the bog
standard PVC tiles then you can only lay these using tile adhesive. To
build up the floor, you could use a 25mm sand/cement screed (although this
is a bit on the thin side) before laying the PVC tiles. If they are ceramic
or glazed tiles, then you can put these onto a bed of "cement".
