Grout or Silicon

[dhsanta65]

Doing a 15m2 conservatory floor this week onto concrete base. Just wondering is it best to use silicon round the edge or will grout be fine, there is no skirting going on just bare brick.

a neat grout line should be OK!!mate IMO

[united]

I say silicone mate

Allow for expansion of the walls

[david campbell]

grout would be fine but i would prefer silicone

[Rich]

Silicone IMO. Grout prob would be ok but it doesnt hurt to play it safe.
Silicone it then you know it will hold

[doug boardley]

silicon for me

[whitebeam]

On that floor I do a grout but silicone would be preferable

[Ken Bruty]

I would say silicon, for one it will be quicker for you, 'cos trying not to get grout up the brick slightly will be difficult and slow going imo.

[user123]

Silicone here, too, looks more professional IMHO

[irishjas]

ya you best go with silicon it is the safest way regarding the brick and what the grout would do to the color of your wall good luck

[timeless john]

What colour is the grout and can you use a silicone to match the colour?
I'am going to sit on the fence here and say its up to you.
If you mask the brickwork then a grout line will not mark it.
If you can get a clean silicone line of the same colour without brick dust and bits and keep it smooth - great.
We had to do a report for a conservatory company a while ago where there had been movement of the internal floor - by a very small margin. The grout had stuck to the brickwork and pulled the glaze off the edge of the tiles. Included was my observation of Open Cast mining less than a mile away and the possibility that this may have caused the movement!

as united said silicon to allow expansion. the joint between floor and wall should be left clean [no debri,glue ] better to be safe than sorry,you are the one to get your butt kicked if the floor crackes due to expansion.

Cheers guys, mapei grout to be used so I will be able to get silicon to match, as most of you have said better safe than sorry.
