Tiling
Anonymous user 20 April 2011 - 4.16 PM
This is certainly not a common practice, this guy is a cowboy, and its people like him that give good honest tradesmen a bad name. I would ask for the money back, ( I expect she paid more for a bodge job than what a good tiler on this site would charge) It wont be long before those tiles are falling of, he should have stripped the old ones of first, cleaned the walls, repair and plaster damage before tiling using a good water proof tile adhesive.

I have to say that's one of the worst excuses to cover up a bodge job i've ever heard..........it's even worse than a 'decorator' plastering a ceiling with easi-fill joint cement i saw recently. How do these people sleep at night? Report your 'tiler' to Trading Standards and try and get your money back. If he refuses,take him through the small claims court. Good luck with everything. Carl.

I've been in the building trade for over 20 years and never seen this done! But having said that, I see no reason why this wouldn't work. Silicone will pretty much stick anything... wait and see if they drop off, I'm guessing you could be there a long time!

In fairness to the tiling operative,using silicone will be more effective than several of the methods listed in the given answers,firstly unibond is a water based adhesive,of course it does dry alas when a water based adhesive is applied on top the pva will reactivate and serve no useful purpose,secondly,water based adhesives rely on a permeable substrate to absorb the water within the adhesive in order to cure,tiling on to a non permeable substrate such as tiles is pointless with a water based adhesive,an adhesive with a chemical curing agent is required,nuff said!

You shouldn't be using PVA when overtiling! what happens to PVA when it gets wet? It breaks down and causes a weak bond between the two. Proper cleaning, and then priming with a branded tile primer, ideally from a proper adhesive maker..Mapei,Weber, Bal etc.... dont unibond!!! :(

Not the absolute best way of completing this kind of job; can be acceptable to a limit but, in my experience, removal of old tiles and making good wall surfaces and retiling accordingly is the better standard.

Where to start with an answer to your question. Wrong. wrong wrong. and the news doesn't get any better. Between the adhesive quality and the suction from a notched trowel application you have a good stick. You can tile on tiles, If the original tiles are cleaned and a high quality adhesive is used. domestic grout is only water resistant. so as moisture gets behind your sisters tiles.The silicone will separate from the tiles and the wall will become live. Only the grout holding the tiles together but, not to the wall. It will need to be redone at some stage soon. I'm sorry for the bad news. Peter

no its not right. you can tile over existing tiles as a last option, but we never do. always best to remove, prep the walls and re tile. if he did use silicone then i wouldn't expect it to last too long! he should have primed the tiles and also used the correct adhesive. tut tut!!!!

Hi, this is not common practice and in my opinion they should of initially tried to get the old tiles off, however if this was impractical then the existing tiles should of been trated with a PVA solution and then overtiled using an appropriate adhesive. Hope this helps, Regards Kevin

Hi, they won't fall off,don't panic.....ive just stripped a bathroom where a small area had been over tiled with clear silicone adhesive around the top of the bath. The silicone glued ones wouldn't part from the original ones but the original ones came off with a simple blade lift underneath. As for a flexible powered tile adhesive.......what is that?...no such thing as flexible tile adhesive and grout, or is that the one you use to stick to floorboards!!!(never)........also how do you Prep tiles for over tileing??....unless he used a poor quality silicone adhesive you won't be seeing any tiles falling off anytime soon........I have been in the trade for 35 years, had 3 rentals and worked on countless council jobs,I have used this method and NEVER had a tile come off and that includes public facilities maintained by the council......

it is ok to tile on old tiles as long as the old tiles are not loose. tiles should only be fixed with tile adhesive. it is certainly not common practice to use silicone to stick tiles anywhere.

No it is NOT correct. Over thirty years in this trade and I don't know whether to laugh or cry. The only time anyone would use silicone or hot glue to stick tiles up with is in tile showrooms on boards. And that is only to make it easier to change the tiles when discontinued. Stop the world I want to get off!

Good god..i have just seen this post and had to reply. the (so called-tiler) how can he even use the name "tiler" he is no tradesman, just a cowboy when i trained a collage i used to watch the tilers learning the job "its a true skill" Like all materials we use in building trade they need a key first to even stick to the wall, I'm no tiler but even i know to use silicone to stick tiles on a wall is just bad, as silicone always separates over time

No you should not use silcone to stick tiles it should be a flexible powered wall and floor adhesive. Also it does help to clean and score the original wall tiles to get a good key to the wall.
