premixed adhesive tubs advice?

[lcowner]

im no expert and have only done a few splashbacks,small jobs for myself and family..what are ur thoughts on using premixed tubs of adhesive?i got turned of using them as i seen a job that a guy done on a bathroom wooden floor for a friend where he used shop brands woodies own premixed tubs and it was a disaster the whole floor had to be lifted (by me) the adhesive just never went off/cured?it was only 2 metres in all luckily and was lifted and cleaned up in 10 mins and managed to save most of the tiles,i always mix my own adhesive out of fear of the above
now maybe he did not prep right or was it the tubs of ready mix?

it would be a lot easier to use the premixed stuff as it saves time ect

Tubbed gear is fine for ceramic tiles on a splashback, or even a bathroom wall (provided it's not a wet area). Floors? No, not really, although you can get Unibond ready mixed floor adhesive. Not something I'd use personally, but you can.
i can see the appeal of ready mixed, especially if you can't get the cement based adhesive at trade prices..

There is nothing wrong with using ready mixed adhesive within the right environment.
Max tile size 300x300.
I would never ever use a tubbed addy on a floor, I know there is stuff out there but not for me thanks.
I still use GreenStar on kitchen splash backs if the tile permits this.

I thought we'd covered wall tiles!?! Lol! Ceramic (not large format)? yes. Porcelain? no. Stone? no. Glass? No. Mosaics? No. Anything bigger than 300mm? No.
I don't really understand what you're saying about the porch!?!

When you say paving brick, what do you mean? Concrete slabs?

I have used the tub uni-bond floor adhesive the customer got a few tubs,did not want to use it but was surprised, its not that bad its a bit like bal flex it went really hard I would not use it on a regular basis though.

Prime with SBR, pour over a good quality self levelling smoothing compound, fit Durabase cl, tile over. Might seem a little overkill for 2m porch but its the way I'd do it, and I guarantee every job I do.

The long and the short of it is that all ready mixed adhesives need to dry out to gain strength. Anything which slows down the moisture loss, slows down the strength.

So if you had a big porcelain tile on a painted wall, for example, the tile and the wall act like a big flat bucket so the adhesive will take forever and a day to lose moisture go hard.

The main issue with ready mixed adhesives on floors is you can't walk on the tiles until the adhesive has dried out and gained some strength otherwise you will break the bond.

Fixing porcelain onto painted walls is a big no no,and not with tubbed adhesive ! :yikes:.

Which do you rate the best for splash backs green blue or white?

Whatever's on special at CTD!!
I had a stack of GreenStar in my garage 40+ tubs & a few WhiteStar so I just worked my way through them when I got the chance.
I haven't bought tubbed addy for a long time now as I almost always use Weber powders
