Is this a silly question?

I have one set

I have two sets, one large and one small 🙂

😎 never had the need for them so I have none

Got to admit I seldom use mine these days due to the tiles I am fixing . Generally tiling up from the floor .

I usually set a datum line with the laser and tile from the floor. By the time I've got to the "staring at the wall from sitting on the bog" height I've generally managed to get it reasonably straight.

Long straight edge propped up with a stack of tiles each end.

Well I've finally made a start, and very happy with how level it is. Only question I now have is should I have left an expansion gap between the floor and wall tiles? Looking online people seem to say you only need an expansion gap for commercial large scale jobs or natural stone, this is just porcelain. Thought I'd best ask before I do the rest of the room. I used to put a tile spacer between it but decided not to after looking online this time

You should have a gap between wall and floor.

Leave a gap between wall and floor tiles 2/3mm and use colourmatch Silicon

 

[Jon329]

Yeah I'll be using Silicon. I've only done these 4 tiles above the mosaics hopefully they'll be alright, I'll use the spacers on the rest. Theres some fluctuation in the mosaics anyway so probs got a few mm in places
