Best tile adhesive for Heavy Terrazzo tiles On wall - Tile Advice

[Howard]

I am installing heavy terrazzo tiles (size 400mm x400mm, and 20mm thick) onto lower part of bathroom wall up to height of 1200mm and also on the bathroom floor. They weigh 48kg/m2!. I am using the approriate backer boards on the floor and wall. But I am unsure as to the best adhesive to use. Thinking about Keraquick and latex plus from Mapei but i have had conflicting advice and, as a beginner, I don’t want to take any risks with these heavy tiles. Any advice welcome! Thanks.

Can anyone help? Heavy terrazzo onto KERDI-BOARD - has anyone done this? If the tiles are only up to 1.2M should I use mechanical fixings for the tiles too? I need some experienced advice!
