Thai's the problem in this game to many know it all who don't take the time to understand the products they use,as for builders they are in a class of there own

[beno]

are you guys saying that you get a perfectly plumb and flat wall when tiling floor to ceiling using 600 x 600 or 600 x 300 porcelain or rectified tiles by notching your wall only,

[Esclusa Ceramics]

Well that all depends the builders ability to give you a perfectly flat & plumb wall. We don't live I. A perfect world so of course there are times we need to build out tiles a mm or 2 to avoid lips. But spot fixing tiles only without notching is a different story.
How often do you see builders bust tiles fixing there towel rails etc because the tiler spot fixed his tiles allowing voids between the tile & wall.

Good method is to notch the wall, stick the tile, if it then needs packing pull it off and butter up the back where necessary, this gives you proper coverage. I know it takes longer but you need to just charge accordingly. You should be checking the walls before you accept the job and if they're no good, get them fixed or don't do it. If the walls are no good and you take the job on and decide to spot fix because of this, you will be held responsible for any failures, not the builder that built the walls on the piss.

Spot fixing wall tiles does not meet the aussie standards! A tiler on the northside of Brisbane found this out to the tune of $28,000.00

[beno]

what happened exactly, did they fall off

[Mase]

Builder refused to pay him & said take me to court and you will be re-tiling all walls because they don't meet the code. Thats what the tiler told me!

As far as stacked stone is concerned, the cost of Latapoxy 310 isn't an issue, as firstly, I charge hourly rate plus materials, secondly this adhesive is for spot fixing so you don't really use that much. Although, as you press the stone onto the wall, it tends to spread covering most of the piece.

It really depends on how much adhesive you use when spot fixing stacked stone

Spot fixing wall tiles does not meet the aussie standards!

Not always entirely true.

The Australian Standard for tiling doesn't override adhesive manufacturer's recommendations, in fact Australian Standards and Manufacturer's recommendations are viewed at a more or less equal level, with the manufacturer's recommendations winning the argument if there is a dispute. You may note that throughout the Australian Standard it says: "in accordance with adhesive manufacturer's recommendations"

Therefore, if the adhesive manufacturer recommends that an adhesive is for spot fixing, then spot fixing actually meets with the Australian Standard. ----> Latapoxy 310

[FrankM]

Although I thing if you read Mr Esclusa reply again you will find he said kera/iso would be your best option, he was only giving a cheaper suitable alternative.

What I was saying is that the Mapei technical department is unlikely to be of the same opinion.

Have you ever had issues with spot fixing stack stone Frank- sometimes I find the pieces aren't glued that well together?

No I haven't. I actually use Latapoxy 310 to glue the pieces back together when they fall apart.

[Screed master]

Your actually wrong Frank. The S2 Ultraflex Quick was recommended by mapei rep.
Or maybe he is rouge agent trying to destroy Mapei.
And I think regardless of what any manufacturers instructions say regarding spot fixing tiles it still isn't correct procedure.
We are talking stackstone here it falls apart you said so yourself.
