Mosaic Floor - Tile Advice

[Stocks Tiles]

I started a 60x60 kitchen floor today in a new build and have to quote for the bathroom and 2 ensuite floors which are all going to be in mosaics. My question is, these are going onto chipboard flooring and what would you recommend to use preparing it to maintain a flat finish to tile onto? Hardie? Ditra although the gaps in them I assume would be a nightmare? Any advice would be appreciated as its a first for mosaic floors and rather get it right easily than make a mess the hard way!

Thank you ​

HB, Ditra no good for mosaics

I'd latex too, give urself a nice flat smooth surface if they're small and it's new to you.
