Hello,

Was wondering what is the best flexible grout for a polished porcelain floor with 2mm joints. (Tiled on a floating floor)
Was advised by tile shop to use Mapei Ultra colour plus, adding flexible primer?? But grout has cracked, well more sort of come away from the edges.
Tiler happy to come back and put right but talking of using epoxy grout? Wondred if that sounded correct or not?

As an absolute no nothing about tiling lady, I have spent ages trawling through the internet and it would appear that a flexible adhesive with no additive would be better? Read Bal superflex (not wide joint) sounded good? I am of course ready to be corrected🙂

Ultra color plus grout should not have an additive added to it as its already flexible.

try the Bal non flexi with Bal GT1

Mapei is the best. It already has polymers in it which means its already flexible. Used on loads of jobs, best by a mile.

As a few others have mentioned use Bal standard grout and use bal gt1 additive! mix the bal gt1 50/50 with water and mix this togeather and then add your grout! you will have to measure the grout powder and the gt1 and the water exactly if you have to mix more then one batch so as the colours are identical! There maybe other makes you could use but I worked on a floor which was tiled by another tiler which was floating and they had the same issues! 3 times the tiler re-grouted it and it cracked everytime after about 6 weeks! I used the bal with the gt1 and it has been there for 9 months and so far no cracks! but there is no guarantee as the prep work was all wroung on this particular job!
I contacted bal before i did this and they advised using the gt1 at a 50/50 mix and this is the most flexible method that they do! They also advise NOT to mix there gt1 with grouts that are already flexible as the polymers are different.
There are probably other makes you could use but this one worked for me (so far) Its worth giving it a try to see if it will work.
