grout on manhattan blanco tiles

[Terry7556]

have been working on a bathroom over the last week or so and the tiles supplied by the customer were different to any we have used before. they were monker manhattan blanco and as you can see from the photes they interlock.
the advice given at porcelonsa was to fully grout the tiles, every groove, but it was hard work and the grout dried very quickly.it was mapei anti mould cloured grout, white as you can see.
any one used these before and can offer their opinion or advice View media item 46187 View media item 46188 View media item 46189 View media item 46190 View media item 46191 View media item 46192when we laid them end to end we left a small gap, 1 or 2 mm, we should have had them touching with no gaps

muris this is almost two years old lol
in the end we just grouted the lot,every groove in every tile
it was hard work
do not do it alone and work out before hand how you will mix your grout and your follow on mixes to keep it consistent
seem to remember that the wall just swallowed the grout, used a lot more than we expected to use
