How much movement can this stuff take?

I've tiled our just-built utility room with some Unibond flexible adhesive,
and grount, designed for wood floors and it's fine, and now I'm working in
the bathroom and I want to use the same stuff.
The kids bedroom is next to the bathroom, and the rooms are seperated with
an airated concrete block wall built on the floorboards. Since I've been
working in there, I've noticed the floor has some 'bounce' to it if they
are bouncing around their bedroom (as they do often). Joists are a 12'
single span with these two rooms above. The block wall appears to be fine,
with no cracks in the mortar.

Will I be getting into trouble with the tiled floor at a later date or
should this adhesive cope with that?

I'll leave it to the experts to correct me, but I was of the
understanding that it's ok if the whole floor moves, what you don't what
is parts of it moving differentially.

If it's overboarded with ply and then tiled, as we have ours, then it
should be ok...

I don't like the finish on the Unibond as a grout though, I'm going to
use a different product next time

I used the Unibond too, and agree that it's not nice as a grout -
a sort of dirty mid-grey and I used a suitably coloured BAL grout
with GT1 admix to make it flexible. BAL does a colour which you
can see at a good tile specialist so you can choose the best
colour.

I pulled up the floorboards and put noggins underneath and that
made the floor feel much more solid. I agree with other poster
about the type of movement being relevant. The plywood sheet and
the tiles themsleves lend a certain amount of additional
stiffness.

But now to the serious bit. These children are evidently not
being bought expensive enough trainers. Really good ones have
impact-absorving cushioned soles designed to protect the joints
and organs during marathons. Please stop for a moment to consider
the poor wee bairns' standing among their peers and their social
development. What it costs you now in top-line trainers will be
saved later in cracked tiles and divisive legal battles with
psychologically damaged teenage sprogs.

I have to lay some floortiles on a wooden bathroom floor. I plan to
reinforce with plywood etc to get a stable base and have been looking at
the BAL product range having been horrified at the B&Q prices for the
unibond flexible adhesive ( £13.98 for 1.8 sq m and £22.98 for 3.6 sq m)

A couple of questions

Which BAL product did you use? there seem to be several that are
suitable for tiling onto ply, some two part,. some one part with an
additive. Several seem to be alarmingly quick setting especially as I
will have many cuts to make.

How do BAL prices compare to Unibond?

I paid less than £5 per sq metre for my tiles (in France) and have 5 sq
m to lay. It goes against the grain to pay nearly £7 per sq m for the
adhesive. Are B&Q / unibond have a laugh at the DIYers expense? btw I
have not found a French flexible adhesive, only the Brits would try to
tile a wooden floor!

Maybe I should use a standard cementaceous floortile adhesive with BAL
flexible additve?

Yeah Ok that is at least four questions but.........
