Chipboard...

[Brindle]

Yes, that old chestnut folks!
I've advised customer of backer boards etc, but he happy to go with Bal Fastflex with the additive, along with superflex grout. Only snag is he's now had a fit at the materials price. I know I could convince him ok of the need, but have you successfully tiled onto CB with a cheaper alternative that is longlasting?
The tiles are 30x30 Ceramic, kitchen floor, 3 yr old bungalow, floor very solid..

Is this a floating floor mate..?..

 

[Brindle]

Not entirely sure of the difference...doh!

 

[DHTiling]

Is the chipboard onto joist's( fixing's usually indicate this ) or is it tongue and grooved with no fixings.. normally laid on kingspan type insulation....hence floating floor( excessive movement)..........

Topps do a 2 part flexy, very similar to the BAL Fastflex but without the gaurantee

If it is a suspended floor and not floating, have a look at Adrdex-flex 7001 and P51 primer. it is called the Ardex timber system. I can get the Ardex for around £27 a bag and you can get around 6-7m2 out of a bag if the floor is flat.

Thanks a lot fellas. If it's floating floor, does that limit the options further then?
I think it is actually. I will look at the Topps 2 part, price that out for him then the risk without guarantee is up to him. The job is through Topps so I will get materials from them (as I always do actually)

If it is a floating floor, it virtually eliminates the possibility of tiling onto it! The movement in the floor will crack the tiles pretty quickly in most cases.

Info Spot.


Chipboard in bathrooms the green stuff makes manufacturers cringe they are all scared of it.

The blame goes to good old central heating !

The changes in temp releases a wax used in the green board manufacture so muffs up adhesion.


Now you understand it :yes:

Personally I ply any chipboard floor over 5/6m2 with 6mm

[Brindle]

Thanks a lot. I know for future reference. The customer wants to go ahead with the Bal 2 part adi now. Bal specify it's ok on ChipB. I would have rather ply or tile backer board but hey ho, fingers crossed. I've told him no guarantee it won't crack!

I can never understand why people won't pay that little extra to have the floor boarded correctly, whats better, a cracked floor that costs a bit less or a sound floor with no cracks that cost that little bit more???:huh2:

People need to start listening to the tilers advice!!

 

[Brindle]

I think he was worried about the extra height - I would've gone for 6mm hardibacker, then 1 part flexi. Plus it's one of them - the neighbour had theirs done and there's only a few cracks, and it looks ok.........

Your customer wont listen to good advice - tricky. The Fast Flex is the best bet, we have used it in out of the ordinary situations and one offs and it was the only adhesive I would have trusted to do the job. I can also vouch for Ardex 7001 - using it for 2 display floors at H&G onto chipboard, laid loose and not retained on open sides, and only duck taped together; yes as bad as you'd want. Well it only had to last 4 days, (of a lot of footfall mind) but we were intending to do a good looking job - they were gardenset displays, fully dressed - The 7001 took it on its stride - there was no seam cracks or loose grout at all and then since we had to break it down at the end - crikey did that stuff take some getting apart!!
Given that it wouldnt last very long if this was a 'real' floor, however it was interesting doing it and seeing how well the gear worked.
Good luck. Make him sign off on it being done that way against your advice. These things can come back to bite you!

Seriously, why do some customers think they know better than professionals who do this sort of thing day in and day out? It annoys the **** out of me.

 

[Brindle]

Bal state that the fast flex is ok on floating CB floors so I'm fairly happy it will hold up. If not at least he might change his mind and let me strengthen his bathroom floor when he has that done
The tiling bit would be easy if it weren't for the bloody customers ey!
