Soon ( ish ) will start tiling the bathroom floor . Have a ditra decoupling mat ( but strangely no adhesive ) . On my order for the floor tiles it’s states 

“ porcelain tiles require a polymer modified adhesive “

I’ve been using this adhesive for walls - it doesn’t mention polymer modified anywhere in the blurb though the pack says  “ porcel bond plus “ - so I assume that means it’s ok to use ?! 
 

Though this adhesive is expensive; it mixes well and bonds hard as rock .

@pocster All I can add is that we used this BAL flexible adhesive for all our porcelain ground floor tiles back in 2015. We didn't use a decoupling mat and tiled onto concrete with expansion joints at doorways.

Crumbs ! That stuff is even more expensive!

Uncle Nick aka @Nickfromwales - just keeping with the BAL range . Which one do I want for my floor tiles ?

Mainly screed with some marine ply . Decoupling mat ontop .

Expensive just to stick a tile down ! !
