Floor tile notched spreader

A post I read says use a 20mm half moon notch, why do you need to use such a large notch trowel for laying floor tiles?

Wall tiles go on using a 5-6mm notch so when the tile is set in position the bed will be ~ 3mm.

A 20mm notch floor trowel will end up making addy bed over 10mm thick. Why is this thickness needed?

There may be an obvious answer from a pro but if a 5mm notch can give full coverage then why is a 20mm notch needed?

I'm not questioning the norm, just like to understand why the norm is so!

Always used a 10mm myself using a 20mm will give a bed thicker than the tile I would imagine

20 mm serated trowel used on really large format tiles mate, i use them on 1200 and 1600mm porc etc

Sorry to but in but why does large tiles require a deeper bed, just for future reference

my personal take on it is, if you use a 10mm trowel on such a large and heavy format tile, its just gonna squash the addy, use a 20 mm trowel, and ya gonna have a bed for the tiles, not just squashed up addy, also you get more coverage

JCT is right, plus using a bigger notch gives you more play with the tile especially on larger tiles.

Sometimes you can use bigger notched trowles to get over poor floors/walls.

Thanks for the info guys, tiling is pretty new to me, I'm a painter really but where I work now I end up doing all sorts of things, pulled a trowel out my paint pot the other day and laid some bricks lol I like it though its like free practice

lol no worries fella. We all started by giving it a go in Tiling. My preference is 5mm square notched trowel for the walls and 10mm round for the floor. I'll sometimes use 8mm on the walls for larger format tiles if the wall is a bit out.
