Tile height using Schluter Ditra?

[HardTarget]

Hi guys, have not got round to tiling the bathroom and kitchen floor and was wondering how high the finished tile height will be once completed? Tiles are 9mm thick and I will be using the Schluter Ditra as recommended.

What's the substrate (the floor surface that you're tiling to)?

I will be tiling onto plywood using a 4.5mm notched trowel.

Is that 4.5mm for fixing the ditra down or tiling onto the mat...

 

[HardTarget]

both i think? Sorry10mm for the tile to Ditra. Not sure if this is the correct size for laying 300mm x 600mm x 9mm tiles on to the Ditra?

As long you back skim the tile, if you find 10mm dos'nt give the coverage after fixing a tile down and then lifting then try a 12mm.

if I was to use the 12mm what would be the overall height including tile? I know it should compress, but not sure by how much. Just I need to know the finish tile height and I have never used this system before.

About 17mm including the tile fixed, 4mm for ditra and adhesive, adhesive onto ditra and tile, again about 12-13mm.
When you trowel onto ditra with addy use the notched side it makes it a lot easier to fill the voids.

Cheers Whitebeam! I will be using Tilemasters Ultimate adhesive as this was recommended by another forum user? Its just I'm still unsure by the term modified and unmodified.

Not one I've used to be honest, more of an American use of words, we tend to use flexible which you will need.

Thanks for clearing that up mate!

Is that a misprint? I would have thought better to use the flat side of trowel to fill the "ditra holes" and then the notched side over this to provide the "ribs" of adhesive to bed the tile (back buttered) into.

I think it might be. He might mean skim with the flat side to fill the voids. Then trowel as usual. And also back butter the tiles.

Those aren't coming up then.
