In the thread "Is it OK to Tile and Grout the same day",
I was concerned about the way in which a 'professional' tiler was going to
do a job for me. I'm suspicious enough now that he's not getting the job.
Since other tilers I've phoned can't do the job for weeks, I'm considering
doing it myself.
I've tiled part of my kitchen before myself and it seems ok 4 years on, but

Adhesive. (I didn't grout it.)
After about 48 hours I tried to force a screwdriver underneath a tile, and
it came off whole with virtually no effort, leaving the adhesive on the WBP.
This area hadn't been primed with PVA. On another area which HAD been
primed, the tile still came off intact.
I'm now confused - in John Schmitt's Tiling FAQ he says

"It needs the merest dab of adhesive to keep it from falling down - all the
vertical load is taken by the grout."
Am I too concerned, or am I just rubbish at putting a tile onto a bit of
Finally, is there any particular brand of waterproof tile adhesive that is
Any help much appreciated, and sorry this post is so long!
