Help!!!! Tiles falling off wall!

[Discount Tile Supplies]

Lily When you re tile try not to put the adhesive on so thick. To thick = tiles fall off. Tub adhesive is a good product if used correctly, even if its fix and grout made by Unibond.

I was trying to work out some comments from earlier "pros dont use tub adhesive" "that type is rubbish"

There must be 350 topps tiles, say 100 tile giants 30 or so tile depots, 500 tile independents and say another 100 distributor showrooms 300 BQ 150 Wickes etc (i could name many more) in the UK.

If each one only sold 30 tubs a week (most sell that a day) thats 46,000 tubs a week. 46,000 tubs is a minimum per week thats 800 pallets.

Is tub adhesive only being used by DIY people fixing tiles? I doubt it very much.

Im not saying tub adhesive is better than powder adhesive but if used correctly it will stick tiles to walls for many years.

Food for thought

The hair could be the old superstition of burying a live cat in the wall when house was being built Lily :yikes:

I think we mean proper tilers use powdered adhesive.

This in turn speeds up the tiling process , as tubbed adhesive takes a lot longer to cure/dry with it being a dispersion adhesive and also bagged adhesive is not affected by moisture ingress if that occurs.

Tubbed adhesive is fine yes, but has its limits and tile size will determine its use, 300x300 being the max size.

And most tiles are larger than that now and staff at a majority of shops need to be educated in what should and should not be used.

I dare bet an awful lot of tubbed gear is sold for incorrect use.

Haha CJ..... live cat, human head or horsehair, it's all been reburied behind some new plaster now so whatever it is it won't escape...or give me nightmares.... Quite enjoyed the plastering malarkey - for a first timer - made a bit too much though but at least I'm learning as I go along so will make a bit less next time.

And I've already bought my next lot of tile adhesive - A bagged one by Mapei - Single Part Super Flexible......

Here's where I'm up to so far: 3 pics before plastering:



1 piccie after plastering:



Just had a thought - do you think all that horrible brown stuff is old PVA from years ago? If so, will it still be active and will I need to remove it before I prime the walls with the Mapei primer? (Been reading your PVA/Primer threads and know to steer clear of PVA al all costs!!...) Thanks

 

[macten]

Not too sure what it is Lily. You will be able to tell if it's pva by wetting it and feeling it with your finger, if it'spva it will feel slimey.
If not I'm sure it will be fine with a coat of acrylic primer (make sure you dilute it down correctly)

 

[Lily Swizzle]

Thanks macten - it doesn't feel slimey when wet so fingers crossed it will be ok. I won't be priming until the plaster has hardened properly so that will give me time to prepare the sink area..... Primer says it's 'ready for use' but also says to 'consolidate dusty surfaces it can be diluted 1:1 with water'. I would class some of the wall as 'dusty' and some not, so presumably it will be ok for me to dilute it 1:1 with water and do the whole wall with the same application.......

 

[Lily Swizzle]

Oops, forgot a bit to that last post:

Or, should I do part of the wall diluted 1:1 and the rest (undusty bits) as undiluted? I'm confused!!

Also, have I got to wait 4 weeks or so for the one coat plaster to dry out before I do anything?

Sorry for being such a pest - you folks are lovely guiding me through all this - and I'm learning loads!!

I disagree that only proper tilers only use powdered adhesive, sorry mate.

Granted powder adhesives may speed the time tilers can walk out of the door but whether it disperses this way or that way used incorrectly it will fail. Powdered (slow set sp) adhesive still take a minimum of 16hours to set before grouting.

I understand the education part that shop staff should know better but it all boils down to people not reading what it says on the back of the tub or bag. All adhesive companies have technical help lines but no one calls them.

3 mm bed for bucket adhesive and 2-6 mm for powder adhesive. But people slapp it on nice and thick like artex.

Most failed jobs are due to not reading instructions and poor prep work, which im sure you will agree with.

U can still fix 30x45 ceramic with bucket adhesive with no problems if you adhere to 6mm trowel 3mm bed. I know Bal adhesives say 30x30cm but they are the only ones who commit to a size and they will cover all angles to say its not their fault if there is a problem.

i tell all customers to use powdered adhesive but they cant be bothered to mix it up as its too "complicated" or "hard"!

Im sure we will have many continuations on this Dave.

How many tubs are sold around the rest of the world m8 ?????????

 

[mz30]

I use more tubbed adhesive on walls than i do bagged and for the original posters tiles i would be using tubbed stuff,but i would have prepped the walls properly first.

Does all tubbed gear not have to pass british standards?then its suitable for the job it states on the bucket. For larger format tiles i agree you need to use bagged adhesive but regardless of drying times it probably takes as long putting up batons etc.

A few more I reckon Deano.

 

[Lily Swizzle]

Thanks Paul - no, I'm not tiling onto paint - that was the mistake I made in the first place and you lovely guys put me right so I've scraped it all off. And the second mistake I made was using unibond ready mixed stuff! I've now re-plastered a bit of the wall and intend using the Mapei Primer and Mapei Single Part Super Flexible Adhesive which I've already bought..... and I'm not taking it all back to the shop again now just cos some of you guys seem to be having a slight disagreement as to what is the best adhesive to use! Please don't confuse me any more!!

 

[The D]

A few more I reckon Deano.

a few is that 2 or 3 tubs ???
