Hi all
Am seeking some advice, just 'evicted' my bathroom fitters due to bad work
, can anyone please give me some impartial advise/opinions on the following:
Is it ok to use bonding when putting tiles in a bathroom?
Do you plaster the ceiling first or tile first?
Do you start at the bottom and work your way up or vice versa?
Does it make any difference if you use large or small tiles?
How long is it reasonable to expect to be left without a bath, sink & flushing toilet?
Honest opinions and advise would be greatly appreciated.
Cheers guys

Bonding plaster or PVA Bonding?
Do you plaster the ceiling first or tile first?
I'd plaster the ceiling first
Do you start at the bottom and work your way up or vice versa?
I'd normally start at the bottom and work up and accross.
Does it make any difference if you use large or small tiles?
It depends what size ?, some tiles are huge and really hard work and some tiles are tiny, which are just as hard.
How long is it reasonable to expect to be left without a bath, sink & flushing toilet?
Was the floor being tiled?
I have not tiled a bathroom for a while now, but I used to refit the toilet at the end of each day and the basin. The bath was out of use for about 3 days, but I took my time as they could use a relatives bathroom just a short walk away.

You should not tile directly onto bonding plaster. If bonding has been used it should be skimmed first.

The tiler said he was putting adhesive and meshing onto the wall then bonding and adhesive onto the tile to pack out the wall, he said the walls were in a bad way, we asked why he hadn't just plastered the walls first, his response was that this would be a better way to do it.

you could dot/dab 12.5mm moisture plasterboards to walls.
skimm ceiling.
tank wet area.
tiling..
get your set out,centre any windows,centre walls walk tiles into corners checking cut in these..not to small a cut..if any re-centre wall, you could try for a full tile wrap round in corners.
then check tiles height wise again not wanting slithers/rakes at top an bottom of wall..i go for half tile or just under.
when all happy, datum walls around room..laser line or chalk it.
start from your datum working down and across checking level/plum now an again.
as for tiles sizes if under 300mm you will be ok for a tubbed adhesive but a good 24hrs before you grout "dispersion adhesive".
if over 300mm bagged addy,single part adhesive, grout after 16hrs,rapidset grout after 3hrs, most good tile fixer will only used bagged adhesive imo.
as for no bath etc..with uhm.

for floor you could lay 18mm wbp ply seal edges/underside with sbr screw to joists then overboard with 6mm backerboards glued and screw.
or
22/25mm wbp ply depends on what sort of budget you have really.

Whenever I fit a bathroom, and I tend to do alot, I always work around the customer. If they need to use it, then it goes in every night before I go home. If not, it is cheaper because it saves time.
I tile first and plaster the ceiling after because it gives a tolerance of 2-3mm where the tiles and ceiling meet. Either way is perfectly acceptable.
Most people tile off the bath and work up, then down for any tiles which are lower than the bath.
Tiles of 20-30cm are easier than bigger or smaller. Larger ones, the corners can kick out if the wall is out of plane. Smaller follow the contours of the wall and depress more easily into the adhesive, thus giving a less than planar finish which is the ideal.
Not sure about the mesh -bonding-adhesive part. Sounds like a waste of adhesive to me as it is about four times thre price of plaster and shouldn't be used for building up the level. May be a way of saving time.

with regard to - 'How long is it reasonable to expect to be left without a bath, sink & flushing toilet?'
the only answer is, 'it depends on what you pay for and what you negotiated'.
Sometimes a job will cost allot more if a toilet needs to be out of action for no more that a few hours. I am just now completing a job where the household had no working toilet at all for over a week. The other option was an increase in the bill. They opted for option a.
