tiling over chipboard floating floor! help needed

[Perry]

Are you insured for bad workmanship ?

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.

im sorry my answer hasnt helped you or cjs or anyone elses for that matter,so your qualifed but have no idea as to what materials to use on the job that shouldnt be getting tiled in the 1st instance ?

im not going to give you any info on what materials you can use as i dont agree that you should be tiling it from your descrition.......i hope that helps. 😉

I've done lots of suspended floors and never had one callback in 6 years. I just overboard with hardie backer or NMP, glued and screwed. Works for me.

Its not a suspended floor, its a floating floor.

Oops my bad

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.
