Silicon in dormer room

[El Kabong!]

Hi,

I am proceeding (slowly) with my first tiling job.

Floor tiled, all walles tiled, floor grouted.

I am about to grout the walls (3 walls of 60x30 and 1 mosaic wall.)

However, it is a dormer room, so one wall is only shoulder height... and 2 side walls are 'diagonal' from shoulder height.


I have been reading up and feel that it is best to use Silicon on
- all 4 edges of the floor
- where shower tray meets floor
- all vertical corners

But, should I Silicon where the tiles meet the slope of the roof?

The reason I ask is, that my grout gap is 3mm, but the gap to the roof varies a bit, as the roof wasn't straight, and it was my first time doing these type of cuts. I am please with the cuts, including some curved ones right at the top where it meets the flat roof, but overall it varies from 2-5 or 6 mm on the way up.

I was hoping to fill in it and paint it white to match the sloping ceiling, and ceiling paint, but if it is likely to crack.....

fill with decorators caulk paint ova

What is the difference between filling it in with caulk and painting, and filling it in with white Silicon (the paint will be white).... or even filling with grout and just painting the grout white?

 

[suave]

its flexible and can be painted,Silicon on its own be ok a suppose caulk be cheaper

ok, it's just that I will be using gray Silicon in most places, but around the toilet/sink I will need white, so will have alot of white left over... no point in using caulk instead unless there is a reason to. Although it might look nicer to have it painted exactly the same colour as the ceiling.....

My entry into the Job of the Month comp this month is exactly how your describing. I used Silicon, white because i was using white grout. But i'd co-ordinate the Silicon with your grout colour. Mask off the ceiling before applying Silicon and you'll get a nice neat finish.
This is the cheapest option too as presumably you already have the Silicon for the rest of the room. But what it also means is when you come to decorate the ceiling now and in the future the paint will wipe straight off the Silicon bead.

Thanks.

I am using BAL grey grout, comes in a bluey bag. I am slightly worried that I can't match the Silicon exactly to it as I think they only do a gunmetal grout instead of varying shades of grey. If it isn't an exact match then I feel it will stick out a bit so am tending towards doing something whiteish that I can paint.

 

[AliGage]

Smoke is a darker grey than gunmetal and they do a co-ordinating Silicon with it. It'll be more expensive mind. Don't know if you've already started the grouting yet, if you have i'd say a close Silicon colour to BAL's grey might perhaps be Webers Silver Grey. Available at CTD, if there's one near you?

Personally i use caulk thats paintable to match the ceiling colour, Silicon is not paintable or atleast most is not...

 

[El Kabong!]

Thanks guys. I think I feel more comfortable with the paintable caulk idea.

Bit confused by that as surely it's the gap from tile to ceilling you want to fill. So effectivaely it's the wall not the ceilling. However, choice is yours, i'd be using Silicon though if it was me.

 

[El Kabong!]

yes, the space between the tile on the wall, and the ceiling, so I am filling a gap that rests on top of the tiles.
So, yes, this gap actually goes all around the room, even on the wall that is not sloping.
