Hello all

I'm going to be laying some granite floor tiles in my hallway this
weekend ontop of some old tiles and some concrete and have a few
questions:

1. I have been told I need a wet cutter for granite, can anyone
recommend a decent cheapish one? the tile size is 30.5x30.5.x1cm. I
will be using it more than once as I have a utility room and kitchen
to do also so it'll probably be more cost effective to buy one

2. I plan to lay some self levelling compound ontop of a smallish area
of the floor where it is un-even. How long will I need to wait before
I can tile on top of this, 24hrs?

3. Should I PVA the old tiles/concrete beforehand and leave overnight
and if so how many parts water to PVA should I use?

4. Can anyone recommend a type of adhesive to use for granite or will
any normal tile adhesive do the job?

5. The old tiles are laid directly ontop of the ground, should I put
down a DPC of some kind maybe a paint over the old tiles? I know the
correct way to do this is to remove all the old tiles, lay a DPC and
then concrete/Screed but that would be a hellish job and I have had
just about 1 to many hellish jobs lately

Thanks in advance

Cheers

Richard
