tiling over chipboard floating floor! help needed

[Arn Wheeler]

firstly PJC dont insult me.im fully insured and never do a bad job ......... and KILTY55 thats rite i am qualified and do know what materials to use i.e addys and grouts but i was just wanting to know if there's anything else out there differnt to what i use all the time.i.e something designed for that.like i say this would have been the first time ive come acroos a tile over floating floor job.and tbf ive got nvq2, diploma level 2 and city guilds and went to plymouth CFE and in the whole course there were know mention of not to tile over a floating floor.'ive even checked all notes and paperwork from college'. :smilewinkgrin: this is meant to be a forum to give people advice and help if needed.not take the mic out of other tiler or try make me look UN professional.any way for any one else that wants to know the customer has two choices now which are: 'the floating floor has been ripped out and then have a concrete screed layed down' 0r ' i lay hardi board over chipboard and screw and glue'. down side to hardi board is that doesn't give me enough clearance on the double glazed back door, especially as theres 15mm natural slate and 10mm addy and 12mm hardi board. :hurray:

Regardless of what some people suggest ,while tiling on floating floors is a pain it is not impossible,using hardi-backer etc is a good start ,a decent 2-part flexi adhesive on top will be a must along with a flexi grout ,expansion joints depending on size.

just a quick google search will give you some solutions ,
I found this at weber(which a lot of the guys recommend)

Although relatively small tiles can be fixed directly onto small areas of tongued and grooved floating floors using specialist products such as weber.set WF21 or weber.set rapid flex, a much more secure solution is to fix a second board over the existing timber. This increases the rigidity of the floor and prevents localised movement, thus making it a far better substrate for tile fixing. If a water-resistant tile backer-board is used to overboard, it will virtually eliminate any moisture related movement.

thank you mz30 good advice taken anywhere you can suggest to buy weber addy at a good price from? as all local tiles shops around me dont stock weber mate.

 

[mz30]

No idea for cornwall mate,there are other products you could use just make sure its a 2 part flex,tbh honest i havent used weber for ages except there tubbed stuff which was very wet,always prefered bal products personally.

 

[Arn Wheeler]

ok thanks anyway....ive used ardex addy and weber flexi grout..but wasnt keen on webers flexi grout as kept shrinking in the jiont, and was far creamy. i prefer bal products too. bal fast flex is a good one too.

i would NEVER tile a floating floor, ive seen many, many failures in my time, it just aint worth it imo..

 

[White Room]

tbh this is the first time ive had to tile over a floating floor.the floor feels solid and doesnt bounce plus its not guna have alot of heavy foot traffic over it. what experience have you had with floating floors then CJ. the ceramic tiled floor that was down previously was absoultely fine with no signs of cracks or any tiles lifting.

any way thanks for that bit of info guys. i will go ahead and tile it and hope for the best......fingers crossed.

A song and a prayer won't help you if it fails, the guys have advised with years of experience on this matter.....your choice at the end of the day though.

I doubt hardi will give it any substantial longevity. It will still move at the joints. I have always wondered if laying a 20mm thick adhesive screed on top of the hardi would make the floor rigid/compress it enough to tile.(perhaps a cement/sand addi mixture)... and then ditra on top for good measure.
Anyone have any thoughts? Surely there must be a way to offer some longevity on these floors?

there's a lot of differences of opinion and a lot of myths about tiling on chipboard. i say go ahead with bal on chipboard - you won't have a problem = just make sure you mix the addy properly, lay a good even layer, and bed the tiles down well.

sometimes they just cant see the wood for the trees

 

[ythan]

exactly pete f, tiling can be very satisfying, best kept simple with good workmanship - just need to ignore the ostriches and the clever folk saying you don't want to do that.

the piont were trying to make is not what adhesive will stick to chipboard, its weather a floating floor is suitable to tile to........do you even know what a floating floor is?

Arn said ''the ceramic tiled floor that was down previously was absoultely fine with no signs of cracks or any tiles lifting''.

so what's your point, andy?

 

[Perry]

Ythan I think sharp was a plant to discredit the forum mate are you prepared to cover any costs if it goes wrong ? lot of guys in the building trade have been doing things for years doesn't make them right

my point is a floating floor isn't suitable to tile , you can take the chance and you may get lucky and not have any problems, but is it really worth the risk ?

where i live there are many eastates built using this method, and i have seen many faliures, the floors are to unstable to tile, and i would not want to charge a customer to tile a floor and not be 100% sure the floor will not fail..

most adhesive company's wont even guarantee there products on floating floors so how can you guarantee your work..
