Mosaic tile, sealing?

[Screech20]

hey guys,

I've got one of these tiles to go on the back of a recessed shelf in my shower.

Am I right in thinking it will need sealing as it will be in a wet area?

The area is made up of MR p-board and tanked with bal waterproofing kit.

If I'm ok using this, can you recommend a sealer. Or am I asking for trouble using a mosaic in a wet area?

Cheers

Tile requires sealing. It's made of Teakwood marble.

Thanks L95, I went for LTP Mattstone in the end after a bit more research.

I gave it 2 coats, layed it and will give it another one or 2 after grouting.

Cheers
