Grout or Silly-Cone in Corners...?

[mmmadman]

Hi All

Well my DIY bathroom project is coming to an end and the grouting is starting.

I am fully aware of using silicone around the bath to tile interface but what about the corners of the room and around the door architrave, what do you guys & gals do...?

Also my grout is off white, would you stick (pardon the pun) white silicone or try and find a coloured one to match...?

Many thanks..........

Cheers..........

Use Mapei silicone and Silicone all internal angles before grouting, let silicone dry before you grout. mapei have a great colour range, sounds like Jasmine will be the colour.

silicone all internal corners and were ever a tile meets a new surface (vanity door frame etc)

Just bear in mind when siliconing up to painted/varnished woodwork that future painting will not stick to the silicone, use decoraters chaulk for these areas.

My plumbers van wouldn't start this morning (ignition switched jammed) so I've got the day off, well thats not scrictly true as I'm going to walk to a couple of jobs round the corner, they are easy jobs with minimal tools.

yes you must use silicone in the corners, Jasmine silicone sounds like what you need and also around door frame etc as Bathfix Bob says.

As above......

Would you always do it this way round Neale? I would have thought there is a higher risk of a poor bond

[doug boardley]

silicon corners fella, and where archs etc meet tiles etc

I always silicon after grouting too, just keep the corners and interfaces free from grout

[pete f]

always after grouting

seen some guys fill the joint with silicone just,set then grout so it doesnt get in then silicone seal up..not sure if this method is good or not but it seems to work for them

Are you saying that they silicone/grout/silicone? Interesting variation!

[kilty55]

yes,looks too time consuming for me though

[doug boardley]

not for me that one Jamie, silicon doesn't adhere too well to silicon

This is what we did...

Siliconed BEFORE grouting. All corners of room. All joints. Allowed to dry. Then grouted a week later.

Why a week later? Our tiler told me the adhesive needs to breath to go off. Air has to get to it and if you grout then its an airtight seal for still wet addy.



Check out (above) the corner of the room. What you can see are un-grouted large format porcelain tiles.

With a bead of silicone already in place.

Also those holes have been drilled into the tiles to bring through electrical cable for a shaver socket and a cabinet light.

The tiles are being allowed to air dry for a week.


(As above - but with a bored wife waiting for her bathroom!)



Roll on seven years to today and the sink and cabinet are fitted.
The grout went in. And the wife was a bit happier !


** Here comes the advert bit !!
Oh and the holes for the cables (closeup above) were drilled with a 30mm diamond core tile drill
specifically designed for drilling very hard porcelain tiles with the PORSADRILL
all in one tile drill kit for bathrooms.

One last point. Because the tiles were neutral, the grout was an off white so we used IVORY silicone - not white.

That way we could get into the tiles and it didnt look glaringly obvious to be silicone. It just blended with the grout.



Ivory silicone let us blend in with grout !

Am lucky i dont have to use silicone much as i dont really do domestic jobs,but when i do have to,i silicone after grouting.

Hate the bloody stuff though

1 purpose of silicone is to cover the expansion joint, if you fill the gap up where will the tiles expand too?

for those sized tiles, i'd have used a cement based adhesive which sets chemically not by dispersion as your tiler stated. max size tile for ready mixed is 300x300, these look to be about 400x250?

[northstar]

grout first then silicone.

They are 600x300s and at the time he used BAL flexi adhesive. It was a few years ago now (7 years) and the big debate was on what the wall would take weight wise. Roll on to today and (fingers crossed) no movement. At the time I was happy to wait a week to grout - I grouted myself - Because the whole house was a work in progress and a building site. But I admit todays clients would not want to wait that length of time! !!!
