It's not about getting better coverage... A 4 mm on that tile should get 100% ... So will a 6, but with the 4 mm, you will have a neater application. You can't get anymore than 100% even though some ppl say "I gave it 110%"... They lying!
I hate that saying, "I gave it 110%"
You can't get more than 100%,
The thicker the tiler the bigger the notch I will use Charlie.
Not saying my way is better, far from it,
If the substrate is perfectly flat then you could use the smallest trowel you have..
