Movement Joint? - TilersForums.com

[Rookery]

I'm fixing 36 m2 of 600 x 600 glazed porcelain onto SLC'd electric UFH onto 10mm Marmox onto screed using Keraquick. The tiling continues into another room of 10 m2 without the UFH. Would you put a movement joint in the tiles at the doorway between the heated and unheated parts? If so, is it necessary to put a movement joint in the Marmox as well? There isnt any joints in the screed itself. Oh and given the above spec would you use a 3mm or 4mm grout joint? Ta.

Leave a movement joint at the door frame, a silicone joint would suffice.

There should be a joint innthe screed at this point. The fact there Is not makes it more prone to cracking across the door threshold...

definitely include a movement joint.
