Been looking at some large (600mmx600mm) grey porcelain tiles in a not-so-local DIY store.
You need to seal them before and after laying them, that is fine.
However, being grey, I am not sure what colour grout would look correct between the tiles, and the tiles look better (I think these ones do), without a gap.
So do you /have/ to use spacers when laying tiles and then fill the space with grout? (BTW. the sticky post has 'tent away from the wall' under the floor section). 5mm seems a tad excessive!
If it makes a difference, I intend on leveling the floor using insulated board, an underfloor heating mat then adhesive (flexible, not decided which one yet). Area to be covered is roughly 12 tiles by 3 tiles (and a very small bit).
