Gap between last tile and ceiling

[FreeD]

One more! When tiling floor to siling in a bathroom...in this case plasterboard/skim ceiling...what size gap should you leave between tile and ceiling and how should this gap be filled? silicone? grout? thanks

[Sir Ramic]

Leave a grout joint, same size as between the tiles. Use either grout or painters caulk.

[ad tiling]

use a flexi grout as standard grout will crack over time

[FreeD]

won't flexi grout and caulk crack? The loft was directly above on my last job and cracks had appeared in all the upstairs ceilings so i suggested silicone was this bad practice?

[CJ CERAMICS]

i have always used silicone on the top line. this was taught to me when i first started as a way of stopping the cracking due to movement from thr ceiling above i cant say that it is the right way but it is the way that was taught to me and it made sense at the time

[ad tiling]

nothing wrong with using silicone i use it,
unless they want coving put up, as for caulk thats
used for painting over so no need to use it

[Dave]

As long as you are not getting silicone all over the ceiling then no probs,,

Hello FreeD.

I dont leave any gap at the ceiling unless I cut them short!
With the shape that we are left with ceilings by plasterers these days I always find it a required practise to cut as accurately as possible to follow the ceiling line.
I would grout to the ceiling with the same colour as the rest of the walls and as silicone does not paint over I would only recommend decorators caulk - if indeed I thought it was part of my job as a Tiler.
Have fun
John.

im with John on this one.

Yea i feel sometimes you can overdo the silicone in a bathroom here and there looks ok but ceiling line and floor line is a bit excessive...but with movement in the loft both caulk and flexi grout will crack hmmm...so what ure saying is grout..then let the decorator caulk before painting ceiling? that mgt work

[Colour Republic]

There would have to be a lot of movement for the caulk to crack, it’s flexible filler for Decorators.

I personally grout to the ceiling, although there is a possibility of it cracking it would in most cases be hairline and not really visible. So personally i'd rather have a hairline crack then shiny silicone staring at me

normally I leave a 4-5mm gap to be filled by decorators with a flexi caulk

[Fekin]

Flexi caulk here too

as most joists these days are what I call "forced" ie not seasoned and therefore subject to shrinkage and warpage, I find it prudent to keep my tiles away from the stresses involved, imho

Use either 6mm or 8mm cornertape with whatever you like - caulk - silicone - polymer

It will look spot on, hehe.
