Question Does Tile Adh Really Need Rubber (flex)

What are your thoughts on this

was removing tiles from a job today and was wondering why we need flex adh,
the job was done at least 20 years ago by me and the adh was not flexible adh there was no silicone around the perimeter and no cracked tiles and to jackhammer up was an absolute pain.

have been trialing a few new brands of adh and cant get over how much rubber they contain

probaly the same as the uk over twenty years the standard of builders has gone down so as the materials used by them .ps the rubber comes from old tires is very cheap .and they can claim there doing there bit for the plannet.had that type of sticky for years bal flex

Fair enough but why flex in tile adh surely the sub should be solid

Eco nonsense cost saving.
And it saves a couple of polar bears.

Well that makes all the difference if it is saving polar bears then its a good thing

yes it should bebut lets face it even a sand and cemment floor to day is not considered to be solid to day decoulplers i ask you?

Norm when lifting a floor i can get two or more tiles up whole not this one mind you it stuck to the wall okay onto bricks yes dot and dab old days and a tight boss during the rescission that we were meant to have

Cant save too many polar bears.
Stop using all those plastic carrier bags. That'll save a few more!

if its not broke dont fix it.well they fixed it now it seams to break on a regular bases .

Got my arse kicked on that job rendered over bricks in main bathroom shower wall before tiling then went to render for two rows over vanity in en suite boss went off like a fire cracker

bang bang

Mind you i still respect him as a top tradesman

the harder they are on you when starting the better you will be in the end

what do they say about all this rubber in the sticky copping with ufh

thinking about this will probaly spell the end of the decouplers if the sticky can do the same job

might be on to something there just need to put rubber in grout and hey presto

with the bal flex no rubber grout needed

is it that good

we used to tile over ply with it stuck like sh to a blanket a night mare cleaning tools after .chopped up a few floors over the years they came up the same as the one your chopping up no cracks in the tiles

sounds good
