Hi folks.
Just a simple question from a simple person ;-)
Tiling up from the bath (dead straight edge), what's the best method of
doing this ?
Start with the first tile resting on the bath rim, or would it be advisable
to leave a small (probably about 4mm) gap by resting a piece of hardboard on
top of the bath edge and tiling from this. I intend to use UPVC quadrant as
a seal when all the tiling is complete.
TIA.
Regards.
Mike.

Leave a gap. I used tile spacers on their side, but hardboard would work.

Why? my approach to sealing a bath is to get the gap as small as poss. to
start with, works for me.
If you want to protect the bath with the hardboard whilst tiling as I have
seen done.
Then jack up the bath a bit afterwards to close the gap.
I intend to use UPVC quadrant as a seal when all the tiling is complete.
Never had much luck with that stuff, seems to get mould underneath before
too long.
If the gap is negligible then its easy to make a neat seal with silicone.

TIA.

Thanks for that BillV.
I doubt I'll will be able to jack the bath up a bit now after all the work
getting it right in the first place, i.e.. (the panel is now spot on for
height from the tiled flour) + all the other problems like getting to the
back legs & brackets and putting a strain on the plumbing, albeit only a
small amount.
I have used UPVC quadrant on many a window frame with no problems of mould
if the correct silicone has been used, (UNIBOND High Performance bathroom &
shower, which has very high anti-mould properties) and worth paying the
extra for, some of the others on the market I would agree with you about a
mould problem. Might try something a bit thinner now, say a piece of scrap
laminate to start from.
Thanks for the reply though.
Mike.

I agree with the OP - whan I tile to kitchen worktops I always use hardboard
as described to protect and provide a pocket for the silicone which gives a
much better seal.

With baths the situation is slightly different as potentially there may be
movement with the varying weight of the bath in use.

I still think that a corner fillet of silicone has far less adhesion than a
well filled groove of highly elastic (not sure what the elastic modulus is
of the"UNIBOND High Performance bathroom &
shower" ) sanitary silicone.

I must say at this stage that the bath in question is firmly secured to a
concrete floor and has been filled to see if there is any movement. I
couldn't detect any distortion even after a few hours. I don't know what the
modulus of this particular silicone is as it doesn't say on the tube, all I
can tell you is that it is "Power Shower" silicone & "Superior Mould
Resistant" with a 35 year guarantee. I agree with you on the small gap
theory having a better adhesion and I am still pondering about fitting a
UPVC quadrant as apposed too just having a silicone one. I might telephone
UNIBOND, their techie guys are pretty good when I've asked about other
various products.
Any more thoughts good or bad, please post back.
Regards.
Mike.
