Mosaic tile, grout before or after?

[32alan]

Over this weekend I hope to tile the shower with mosaic tiles which are glass and metal on a mesh sheet. My question is - not to dull I hope, but got to ask - once they are up and fully dry, do I remove the protective film which is over every one before or after grouting, thought it would have been after, to protect from grout although I can see me pull off the film whilst grouting, but have seen somewhere that comes of before, so best check. Thanks.

Before grouting, what grout are you using, some may scratch the mosaics.

Make sure you have a very fine grout as you will find they will scratch easily. especially the metals ones.

Granfix - Maxigrout - a polymer modified flexible grout. Colour Charcoal not black sorry got that wrong. Seems like a very fine grout. Any advice on minimising the scratching, apart from be very careful of course. The mosaics are made up of 15mm squares and 50mm squares approx. Could I leave the larger tiles (50mm Sq) protective layering on? Or take the lot off? Thanks.

According to the PDF it isn't advised for some tile types as it can cause scratching. You mentioned it was in a shower, did you tank the walls ?
