Grouting Travertine Mosiacs and Border Tiles

[DazJWood]

I am grouting my travertine bathroom tiles. These are honed and filled.

I also have a number of small mosiacs and border (like dado rails) tiles that are tumbled travertine so have various holes that are not filled.

Is the usual practise to fill these holes when grouting? I quite like the holes being there on the border tiles and should be able to grout them easily enough without filling them. The mosiacs though would not be so easy though I don't think I mind these having their holes filled with grout.

Thanks,

Daz

The usual thing to do is grout the holes, if you leave them and the holes go right through the tile it gives any water a route through to the substrate.

Not just that but the holes fill with crap and bacteria.. get them grouted..
