The 70 meter area consists of 40 meter kitchen 20 meter utility room and 10 meter downstairs shower room do u still think I need a expansion joint ?

Yeah I've bin known to be called that

 

[hmtiling]

Not if the areas aren't joined.

 

[Kyle Knowles]

They are joined would u put expansion joints the door thresholds? And in the 40m kitchen ?

Would u use a rubber type expansion joint ? I've seen dural make a kinda silicone u can use as a expansion I've just bin reading the literature

yeah, i used that for the first time a few weeks ago. It's an 2 part colour coded epoxy. I used it on trav as it gives more protection to the edge but if porc i'd use silicone or preformed as quicker and cheaper.

Micro joints - Coloured Movement Joints

It's gonna be grouted with ultra colour plus in mid grey so they make make matching silicone so I'll go with that as they are porcelain tile 600x600 stone effect
