Grout or Silicon

[Gnasher]

Hi

I am tiling a conservatory floor with porcelain tiles and the walls are unplastered face brick. Do I grout or silicon where the two materials join?

Thanks.

There should always be an expansion joint around any perimeter therefore I'd suggest both! Fill the gap with a rubber Silicon then grout on top up to the brickwork. Leaving some grout for when it cracks.
I've filled it just with grout in the past and on settlement ( due to other factors) the grout pulled the glaze off the tile!

attention to brick, with Silicon.
use neutral Silicon or acrylic.
no acetyl.
brick, it absorbs, anointed.

Grouting to those internal bricks is always a pain
