Grout or Silicone - Tile Advice

[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 silicone 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 silicone.
use neutral silicone or acrylic.
no acetyl.
brick, it absorbs, anointed.

Grouting to those internal bricks is always a pain
