HI Can anyone help me with some tile blooming that has happened , laid a floor on durabase decoupling with white regular set tile cement and some blooming as appeared on the surface

It’s not blooming. It’s just damp from the adhesive. I prefer to use rapid set then the adhesive hydrates quicker. How long have they been laid ?

about 1 week

about 1 week

The wetting is where the adhesive has made contact. Hopefully it will dry before sealing. Which sealer did you pre-seal with

Ok. The stone needs to be thoroughly dry before sealing and using a standard setting adhesive will increase this drying time.

Thanks so much so far for your constructive help. I hate to say it but I have sealed them in the photograph prior to grouting will they just take longer to dry out or have I created a problem?

I would commission the heating again like you did when you commissioned the heating of the screed. Nice and slowly and hopefully that will dry the tiles.
