Wrong Adhesive Used...

[Phil Smith]

Hello, I have mistakenly used flexible floor tile adhesive on my concrete screeded floor, I have used the unibond ready mixed adhesive for wooden floors.

I know now that I should have used another brand but since the floor has been laid can someone tell me if it will be ok? It seems to be going off quite well, it's been 24hrs and seems solid although I have not walked on it since the label says it will take 48hrs.

The floor tiles used are 50cm x 15cm

thanks! Phil

They need to come up, what type of wood floor and was you going to use the unibond on the screed floor....

 

[CJ]

So you used unibond WALL grout for fixing your floor tiles??

 

[Phil Smith]

Hi, Sorry if I wasn't clear, it's unibond wooden floor adhesive but I used it on the concrete floor :/

Run in that room & try & stop quick & they will go like a deck of cards!!!
They won't last, take them up now & soak them in a big bucket of water & at least you will be able to reuse the tiles.

Amazing!

Why not give unibond a call and ask them the question. Not the adhesive of choice for most I accept but if it is solid and sets there is no reason why it should not stay in place. You might need to leave it for several days to dry before grouting though.

can u get ready mixed floor adhesive?

In another thread the Op is asking for an adhesive for porcelain tiles so it may be that in this case the adhesive will never fully dry!

Why would the fact that the tiles are porcelain stop the adhesive from drying!?! I personally would ring Unibond, as Alan has said... No point ripping it up if you don't need to. It'll either fail, or it won't.

 

[Dougs Third Go]

is the adhesive for tiles?? or is it for wooden floors ie laminate etc?

 

[Phil Smith]

Yup..

Ajax123 - This is the exact adhesive, not the one in the earlier thread... I just read the title on screwfix and purchased it without fully reading the label. Anyway, I have 3/4 of the floor down, they are porcelain tiles which is why in another post I was asking for a recommendation.

I've checked the tiles I laid on Sunday afternoon and these do not seem like they will move without damaging them so I don't think taking them up is an option, my concern is more long/short term or whats the worse that can happen?

I have emailed Unibond to see what they say, but I will finish off with different adhesive and separate grout.

Hi Doug, its for adhesive for ceramic floor tiles...

 

[steve187]

here is a link - Floor Tile Adhesive & Grout: Wooden Floors - UniBond

it would seem to be for ceramic floor tiles onto 'any' wooden floor surface, would seem to be ok for floor boards, not to be used thicker than 3mm. would i use it 'no way hosay'

Hi, Sorry if I wasn't clear, it's unibond wooden floor adhesive but I used it on the concrete floor :/

The way I read it you had used wall tile adhesive on the floor.
Even so I have looked at ready mixed floor adhesive before & I would never use such a product on a floor installation.
It may be ok, it may not, I don't know enough about the product.
I see it says for ceramic tiles. The one thing I would say that it may not dry out or take longer to dry as it will be a dispersion adhesive & the moisture has to go somewhere & won't soak into a porcelain tile.
I have used plenty of flexible adhesive on concrete floors but it is always a powder adhesive.

To be fair Phil, if you're not going to take them up then I would carry on with the same adhesive. I'm not saying I would ever use that adhesive for one second but you are 3/4 the way through so stick with it (or not as the case may be). The worst that can happen is the tiles will move (debond) and the tiles crack (and you fit the bill for the lot) but if it were me I would rather the whole floor did it rather than only 3/4! Are you sure it's not just the suction effect of the adhesive onto the tiles rather than the adhesive setting? My money is on you being able to take up those tiles with minimal breakage.

I started to prise them out and your right, they came up... going to soak them and clean them now and start again with the correct adhesive..oh well, nothing like learning the hard way!

It will probably save you money in the long run.
It looked as though the tiles were sitting nice aswell.
Keep at it m8, it will look good once finished & you will have the assurance that the job was done correct & it's not going to fail..

 

[Martyn Leeds]

Cool,
at least you've got a decent bucket to mix your grout in now

 

[judge]

When its complete youll be glad (and relieved) you installed them correctlly

 

[StylesTilesMan]

Lol how can you accidentally use that ? . From what i can see, its a floor adhesive designed to stick tiles onto floorboards and such... From my limited experience of doing a floor with pre mixed (once) if you leave it a good few days resisting walking on it I think it will hold myself. I think some of these guys here are guilty of being a little "jobsworth" on this one personally. Floor boards move about, Screeded floors are solid. If you had used non flexible adhesive on floor boards then you would have been stuffed but this way round will probably be ok. OMG i just saw,, you ripped them all up.. oh well,, live and learn burp

"A few of the guys on here are guilty of being jobsworth"??

No we give out advice because we know its right.
"In your limited experience" you stick to the way you do it,
"US TILERS" will stick to doing the job correct the 1st time round..

Can I ask how many m2 of timber floors you have tiled?
& have you tiled direct onto floor boards??
