Got a job on just now where im levelling out a kitchen for a customer using bonding coat. The customer was done by some idiot who tiled their kitchen and put the tiles on the wrong way and made a right mess of the job. They have took every tile back off and ive prepped the walls for bonding out. Question i have is can you tile onto bonding coat if you let it dry right out? or do i need to apply a finish of multi to tile onto? Dnt know much about tiling as ive never done it.
 
Most of the tilers ive worked with are happy to tile onto bonding, they just want it smooth and flat as poss, try and close it in as much as possible for them
 
Cheers lads. They dnt have a tiler yet so i cant even ask him what hed prefer. Wasny want to do the extra work of skimmin to a finish if a gd flat coat of bonding would have done the trick. Would just be extra work for nothin really.
 
Feel for them a bit. Nice couple. Paid alot of money for tiles and this clown put them on the wrong way plus they were all over the place, plus he took 400 for doin it and he wont answer a txt of call from them. To close to xmas for that so need to make sure i do the right job for them.
 
Beddy is spot on bonding is too unstable to tile over . Should be reskim ex with multi and then use sbr not pva before tiling

That said we have done loads of tiling over bonding
 
As long as it dries fully before tilling and is primed with a suitable primer 1st should be fine to tile over

When we had a tiler in our home i just bonded it out and the tiles have been on for 3 years. No problems. Have you ever had any tiles fail onto bonding?
 
Shocking really that people are still doing this but it's never going to stop. Tiles should only be put on to finished plaster never backing plaster, just give it a quick coat of multi and brush it flat then hope that the tiller primes it before it gets tilted.
 
Think ill just give it a coat of finish. Hopefully they can get a good tiler in to get it tiled for them when im finished.
 
Tillers don't care, as long as it's plumb and flat....they'd tile onto paper mashe if it was flat! All you gonna worry about is that it's not gonna suck the living day lights out of the adhesive.... otherwise their tiles fall off and they blame the plasterer......! So bond if up, close it in and seal it up..... You could even do a 50/50 second coat with multi......simples!
 
Still baffles me why people always try and shortcut. If uv ever tiled Ul know it's 10 times easier over board or skim. But people would rather tile or plaster over tiles than hack off and float and set it. Sad really
 
Especially dodgy tiling over tiles as it's impossible to see if your overloading the wall with the weight of the tiles.. Esp heavy large format tiles
 
BG spec is that you cant tile on any backing coats but as long as the tiler primes with SBR and uses a cement based based bagged adhesive it will be fine.
 
we have done lots of work for a national tile com. and they spec. fair face sand and cement. this is always new work not refurbs.
