i know i can get the ardex kit from c t d so i will pop over next week. i wish i had been there when they started sheeting bathroom.

been working on a large floor for a client recently.once i am finnished to floor he is wanting me to start the bathroom, however the walls are plywood, i asked him to remove the ply or overboard. however it turns out this will not be possible due to bath and shower tray installed and pipe work is set in place so it cant be brought forward to accomodate overboarding,
i have told him its not really viable to tile on this surface especially where the shower is and the fact the whole house inc bathroom has underfloor heating installed.
however he is needing me to go ahead and tile the room as is .
so can anyone enlighten me as to what would be the best course of action regarding this, and by that i mean what would be the best .preperation , adhesive , to give this room a chance of not failing after five mins

Listen, you're asking how you can get over this plywood... builder problem.. its down to you to have the balls to tell him how not to prep bathroom substrates, or just crack on and tile it... or don't do the job.. how can we tell you how to swerve, do the job wrong, get over his mistakes... mate, tell him how it is....... only by telling them, will they learn and not do it again.. or just desperate tillers will tile their incorrect tile surfaces.... at worst, don't guarantee it........... ( no disrespect to you )

put it in plain terms to the Builder..... WOOD AND WATER !! Derrrrr @@

listen,/read, i have explained the problem, i am trying to find a way to tile over the ply wood that will give it a slightly better chance than just sticking the tile onto the wall. the bathroom was prepped before i ever seen job. the builder who put the kit up is now gone. the plumbing is set into brick walls and the shower tray is concreted down. so i cant do anything other than walk away or tile it, i am just sealing 80m2 of 600 x600 brazilian slate that i would like to get paid for. also this client runs a fair sized company that could also get me plenty of work,.. . so i dont want to walk away,he understands the problem and is listening but we cant do anything now other than try to deal with what is in front of us. hence the reason i asked the question
so no offence but if you have nothing constructive to reply, dont bother , cheers

The homelux membrane is another option, it's only a couple of mm thick.

Sometimes you have just got to grin & bear it & do the job even though you know it's not right.
I get it on a regular basis with a certain company I work for & I tell them how it should be done but they don't listen half the time but at the end of the day I'm subbied to them & it's not my name against the job.

You have explained why he shouldn't be doing it so i think i would just get on and tank it or homelux it and get the thing tiled and i wouldn't lose any sleep about it mate. I done a bathroom about a month ago using the homelux matting system, seemed fine and so far aint herd anything back (yeah i know its only a month but no news is good news in these cases lol)

I regularly tile to ply with a few builders. Sealfix joints, prime, tank, s1 adhesive with a back skim. It's still possible to complete a successful tiling job onto ply if it's done right.

If you're going to apply a couple of mm of a WPC why cant you glue and screw 4mm marmox?
There will be room on tbe edge of the tray, around the bath and it shouldnt effect any pipework.

I wouldn't be happy doing it but if I really really had to then I'd use the Ardex kit as I've used nothing else for a couple of years now and have total confidence in it. I can also pretend I'm a plasterer whilst doing it as I trowel it on (Can be rolled).It also doubles up as a great waxing kit if it sets on your hands/arms!!
