Thanks Nod These are 9mm tiles so you're saying 10mm on the floor would be best and use the same for the walls? There are so many contradicting views out there.

I'm about to tile a number of walls and floors. I've done a little tiling before but only with smaller tiles so I'd like to check I'm getting the adhesive thickness right for larger tiles; 600x300 porcelain on a wall (one is part of a shower), is an 8mm towel to leave a 4mm thickness of adhesive enough or not enough? The same tiles on the floor I've thinking I should use a 12mm towel to leave a 6mm thickness of adhesive. Again enough or not enough? What are your thoughts? Thanks
