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)..........

 

[surflaur]

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

 

[grumpygrouter]

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.

 

[Brindle]

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)

 

[grumpygrouter]

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!

 

[robbo]

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.........🙁

 

[CBTC]

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!

 

[DHTiling]

If tiling a floating floor it still needs to be stable....this is what BAL recommend before using fast-flex on floating floors...

FLOATING PLYWOOD/ CHIPBOARD FLOORS

Ensure that:
1.The floor is stable and free from deflection.

2.The sheets are dry and rigid and that any fixings do not protrude.

3.Ensure the joints between the boards glued and secured.

In my opinion floating floors are a disaster waiting to happen.....the amount of floors i have been out to see that have failed is ....iv'e lost count... ...

good luck which ever way you go...

Finished the floor today, it's worked out ok...i hope!
The floor feels very solid, the Bal stuff quite nice to use actually.

That's a palace product it take's five hour's to go off as it say's on the bag

Please be sure to use wide joint grout with GT1 additive, this gives the grout maximum flexibility....Gaz

[Brindle]

Cheers Gaz, I have grouted already, used BAL superflex, so hope that is flexible enough?

Is normal wide joint flexy not as flexible as wide joint grout with GT1?

 

[sibs]

My sister tiled straight onto her chipboard bathroom floor with wickes floor tile flexible adhesive tubbed stuff!I did around the edges for her where all the pipes were with the same stuff. Its murder to clean off your tools. I also grouted the floor with bal flexible wide joint grout and the floor now looks great. God knows how long it will last but they are moving and won't be around to see lol

 

[GazTech]

Any adhesives with polymer built in aren't as flexible as a standard powdered adhesive with liquid polymer mixed to it, if iny any doubt as to how flexi you need the product, then revert to powder and polmer.....you cover yourself....Gaz

 

[CBTC]

sibs - your sister didnt ask you, being a tiler, to get the stuff / do the floor? Just struck me as odd, sorry.

 

[sibs]

Hi CBTC
No she didn't. She wanted to do a quick job not a propper one.
She phoned me to ask for some advice as to weather she could tile onto cork. By then she had already got the adhesive from wickes. I told her to take the cork up and over lay the floor with ply of at least 9mm (it is only a small floor and reasonably solid) or 6mm backerboard.
She did not want to hear this because she wanted to get the job done and wasn't too bothered about the finer points as they are selling the house.... so I insisted that she at the very least take up the cork tiles.
She proceeded to tile straight onto the chipboard despite my advice.
Then she started on the walls and that is when I got a phone call begging me to go down to london lol. She had tiled off the flimsy baton of wood that made up the space between the new bath and wall at one end and wondered why she ended up with a v in the middle of her tiles lol.... the baton sloped by a couple of mm either side of the middle!
I am in Telford you see... and she is in camberley so I can't just pop over.... anyway I ended up spending a week there and also finished off her floor around the edges on all the cuts around the pipes etc that she couldn't do.
Hope this explains lol

Seems quite a regular thing at the moment, I,m getting call's to do repair's to the tiling because were going to move, There's going to be a mass exodus somewhere.

 

[sibs]

Just to add to this.... there is a post entitled "straw walls" in the tilers forums arms.... just a problem that I had to deal with before I could even start tiling lol.
My sister wasn't too happy about all the faults I pointed out with my dads and brother in laws initial attempt at boarding out the wall (they had laid the board horizontally onto half inch by one and a half inch batons spaced about 700mm apart and one baton going diagonally to support the middle baton.... and trying to screw it into straw walls which in places had partly disintigrated due to water damage all of which worried the life out of me but I guess they all just wanted a quick fix knowing they were moving.
Well I wasn't going to let them get away with that...not now that I was there! Not in my name!
Some things you just can't skimp on so with a little help from my mate whitebeam and dave and others on here I did it propperly. That wall was very solid when I had finished! I dot n dabbed that plasterboard on within an inch of its life! lol

Yes mate they're all moving to corby I shouldn't wonder :lol: Well at least thats where my sister and her family are going!
I reckon everyone's scrambling for the few mortgages that there are left!:yes:

 

[CBTC]

- it was to the rescue then... families huh! Next task will be in Corby then.

...." not in my name " - like it

Yes CBTC it was me to the rescue ..... My sister thinks I am anal about tiling.... she doesn't understand bless her! And funny you should say that because if they get this house they want to section off part of the garage and build a utility room and guess who's gonna tile it!!!!

 

[CBTC]

good stuff - hope the move goes well for her. The utility room will be a gem I'm sure.
