help - bathroom floor tile adhesive not setting

TBeckett100

adhesive supposed to be groutable in 24hrs but after days I have called the pro's in. Just lifting the tiles now and the cement is still wet, any ideas why?

More information may help indicate why.
What adhesive was it? What surface was the adhesive laid onto as you may have used the wrong adhesive for the job? How thickly was it spread? Did you follow the mixing instructions on the side of the packet exactly? What was the expiry date on the bag of adhesive? I would call the manufacturer as if you got a dodgy batch they may replace it free of charge.

it was evo stick tubbed ready made from homebase, suit for concrete floors. stuff just doesnt dry out. i have scraped it up and think i will take it back.

But you haven't said what exactly is the surface your tiling onto... is it plain concrete or is there anything on it like black bitumen from removing old tiles? Different types of adhesives are suitable for different jobs.

concrete with a bit of old stuck on 50's tiles etc. but even on the concrete, it hasnt set.,

I'd contact the manufacturer then. Homebase might refund you but would be nice to know what the problem is so you can avoid it again.
Not really impressed by evo-stik myself. as evo-stik pva always goes mouldy for me.

sounds like the adhesive was too thick and has not been able to dry out

better off using a dry mix flexable adhesive than tubbed stuff for floors

something like granfix superflex would be best
