Curious.........

[Fred]

I did a quote a few weeks ago , they wanted polished black floor tiles in their main bathroom replaced with non-slip as a new baby is due. The bathroom was only re-newed by last owner several months ago, and some tiles were already lose.

So, I started today, and found that the tiles came up in my hands......... the addy is white ( what made I don't know etc.......) and nearly all is stuck onto 24mm ply the fitter replaced the floor with, and just a light white mark on the underneath of the tiles.

So, I know it is not the ply that was moving as it is solid as a rock. There is also no trace of any priming.

My question is, did the bathroom fitter, who did the whole install, mess up by firstly not priming? not mixing the addy to the correct state? not using flexi addy?

The owners were totally gob-smacked when I showed them the tiles/ply..even they could see the tiles were not properly installed.

I just want suggestions as to what you think went wrong as I feel that would be good to know. Thanks.

More than likely incorrect addy by the sounds of it...and not all adhesives require the ply to be primed...

[wetdec]

Sounds like a dense tile with either too wet adhesive or not a flexi so no grab.........imo

Thanks Dave, I'll be using Bal grey rapid 2 part & flexi grout to re-tile, is a bit of primer necessary then?

[Droopy]

It could be that it was an adhesive that was not suitable for porcelain tiles.

[Dave]

Nope..!! not normaly.....but seen as it has had adhesive already on it then consult bal literature for info....

If you are going ontop of a single skin of ply, then i would suggest that you use BAL Fastflex, Fred.

Dusty backs of tiles maybe.

Could it be that the tiles where fixed with tubbed gear if they lifted that easy?? Just a thought.

Thats what i was thinking when reading this thread...........but you beat me to it by an hour dam

[Fred]

It took me 3 hours with an sds hammer drill to get rid of the old adhesive. Spoke to Bal, two ways; 1st, use fastflex.....client dropped when I got the price, 2nd, ply out over with 15mm ply and spf.............client happier...............me, at home as can't get the ply until tomorrow...............

top fix 2 part only £18 for bag and bottle

He didn't make the schoolboy error of using GROUT instead of Adhesive. You might laugh but I've seen that done myself!

[LM Ceramics]

is tubbed gear was used on the floor would it be crumbly

Thats a good price, my shop wanted £112 for 2 x 8kg bag & liquid.

i can get a 17 kg kit of pci's timberflex 2 part for £35 , granfix ultimate for £38/ 20kg bag , mapei keraquik + latex 20kg for £35 .. used them all without a single problem..bals fast flex is far too expensive

If the adhesive has stuck to the floor, then would suggest that priming was not an issue.
Did the tiles have 100% coverage?
If the coverage is not a full bed, the movement you will get on a single layer of ply could cause a failure.
When a tile fails, it will fail at the weakest bond, if it's a poreclain tile, then that would be the weakest (not weak) bond.
So when tiling onto a single layer of ply, no matter how strong it feels, you really need a 2 part adhesive, which one is up to you, but you pays your money, you takes your choice.
You could try the Dunlop 2 part, similar to BAL you can probably get 2 packs for around £70.
Overlaying with 15mm ply would be my choice.

Fred if you ever need any advice, I'm the BAL product support technician who cover's your area, give me a bell. 07800550460

ah cmon branty you know the score you were a fixer yourself before becoming a suit.. seriously tho , i used 40 kg of granfix ultimate today cost me 70 odd squid how much would the equivalent in fastflex have cost ???

[Fred]

Over-plyed it today........thats when the stupid delivery driver told his boss he couldn't find the house number, and that the next door was being done up, so put the ply in their front garden............... that was 10am, and I wasn't told until 1pm................. I'm not a happy bunny.................... nor was my client.

what adhesive are you going to use then Fred?

Ok Andy I'll be straight. I think there are some good S2 adhesives out there From Many Manufacturers. Granfix, not for me. I used ultimate flex a few times, and it was like trying to spread tar.

When it comes to the crunch. If I had any doubts about the substrate, then it would/will always be fastflex.

As for a suit, never. I wear the same get up as Gaz. Only slightly better looking (and slightly larger size)

[Fred]

I over-boarded with 12mm ply, screwed down every 6 inches, and ended up using Mapei Keraquik.
