Need help

But there is a problem with this one.

Ill be the intructions say mix with a paddle though.

Were the back of the tiles dusty? Did you back skim the tiles with adhesive as well as trowel the floor, this is recommended on larger format tiles.

at last

the problem with the sheds is that they dont know enough about each product they sell to advise you properly, you would do better in the future to shop at a proper tile outlet who have the product knowledge, your tiles should have been dusted down and back skimmed, good luck with B&Q but they will claim fixer error, the good news is that if your tiles come up clean you can reuse them, you will need to hack the addy off the floor though, I dont use unibond adhesives so cant comment on them , try the buildfix as thats made by mapei

hi was the concrete floor dry and dusty and did you prime first

If I'm mixing small amounts of addy I just mix by hand.

Hi and welcome..

If you have not back skimmed the tiles then they will not bond correctly.. these large format tiles have a square grid pattern on the back and this needs smoothing in with adhesive and then pressed firmly into a solid bed of adhesive.. 100% contact is needed for a strong bond..

I have just installed 30 mtrs of these tiles this week.. so no probs with them is all i can report..

I can confirm that Unibond products are total rubbish, everything they make fails instantly.

Unibond silicone goes as black as hell as soon as its in contact with water.

Their tile adhesives and grouts are shockingly bad and used to let me down everytime I used them, you grout a wall and the next day its all shrunk and cracked.

Total rubbish.
