1st time tiling. Expansion joints?

[tilemark1]

Hi

Just undertaken my first ever tiling job, in my own home.
I am tiling an en-suite shower, a 'C' chape. The walls are block and have been scratch coated. Got most of the work complete and am happy with it.
I left 2mm gaps between top row of tiles and ceiling, is this correct?
I left 2mm gaps between corner tiles, is this correct?

I am about to tile the bottom row of tiles and was wondering how much of a gap to leave between the bottom row of tiles and shower base?

Also, when fitting trim at the end row of tiles I butted the trim up to the tile leaving no gap. Somebody made the comment to me that I should have left a gap of 2mm here to fill with grout. I thought it looked neater just butted up against the tiles.

Your comment would be very much appreciated.

Anybody know what make of ivory Silicon sealant I can use that doesnt go black after time.

Leave the same gap at the shower tray..they are fine......

I fit my trims fush with the tiles as well looks neater to me...

As for Silicon as ong as it is anti fungal and sanitary grade it should be fine....there are brands of Silicon that have microban in them as well........and come in quite a few colours to match tiles or grout...

Cheers, good to know I am on the right track.
I found a recommended Silicon called 'forever ivory', which has microban in it.
I was also recommended Seal Guard for grout and tile sealing. It is an aerosol.

The sealguard is supposed to be good for grout etc......I have heard of the forever white so the ivory must be made by the same peeps.....

The sealguard i think you can spray on after about 15mins after grouting as well ....

if you are going to tile the correct way then each wall as to move independent of each other wall ,this is why you used Silicon exspansion joint in each corner same goes for the ceiling as well (movement) tiles will pop off or crack
