Grout questions

Hi Guys,

So I've just about finished setting the tiles in my shower, and I've got some questions.

I used 12x12 tiles with a 4 in band of glass mosaic tile around the shower in one line. There is a 1/8 grout gap for everything.

The mosaic tile is all squares of different materials, glass, stone, etc. Some of the glass is polished, some is etched. The tile did not come with any recommendation as to grout.

Based on my reading here, I'd assumed that sanded grout would be the best way to go. However I know that sanded grout can scratch glass mosaic.

Which type should I use? Is it possible to use sanded grout for the majority of the tile, and switch to non-sanded for the mosaic area? or is that not recommended? For such small tiles, and such a small accent band, should I just use the sanded and not worry about it?

Thanks in advance for your advice

use unsanded for everything. Unsanded is fine for an 1/8" grout joint. Anything bigger should be sanded.

No argument with that advice, but....... With larger tiles I like the appearance of sanded better, and I like its workability better too.

So why not use sanded which works well even if some of the joints are less than 1/8? Some are rated for 1/16" and wider joints, Laticrete for instance, 1/16" - 1/2".

Bear with me, but my understanding is that the Laticrete Permacolor (a sanded grout) has no sand in it, rather a synthetic "sand". So it won't scratch glass.

Of course you would be better off with epoxy or urethane, but if you want to go with a portland "sanded" grout, I'd use the Permacolor.

An interesting alternative that might work (though I haven't tried it) is to use sanded on most of the tile, and unsanded on the glass tile area. Of course this only works with 1/8" grout lines specifically, which is the cutover point for most manufacturers (other widths might work for manufacturers such as Laticrete, as mentioned.)
