Grout depth OK?

[robato]

I've had some new polished porcelain tiles laid (60 x 30cm) by a tiler. I'm not sure if the grout is too low (about 1mm) but they said it was a special effect to accent the brick layout. I don't know anything about tiles but would have expected it to be flush with the tile surface.

I found on cleaning the tiles yesterday, dust and small bits of dirt gets trapped in between the tiles and was a bit of a pain to get out. What do you guys think?

Definitely wrong. Grout lines should be struck level and faintly rounded/recessed - use a soft stick with a rounded end to strike the setting grout just before it firms up. Some architects want grout to be flat level with the tile on floors and walls.

I wouldn't particularly say it's wrong, more of a preference, and in his professional opinion probably think it looks better. Which I get where he's coming from. it's not an issue if you wanted to grout ontop the existing grout to build the level up.

Its wrong. A professional does the job according to best practice, not personal eccentric preference.

These are floor tiles, and with constant washing and cleaning the sunken grout lines will soon be dirty & discoloured.

It is an issue to now attempt to fill in the grout with a thin layer of new grout - grouting should be done in one application. If done now some of the new grout might not take, and will possibly get pulled out with successive washings & floor traffic.

robato,
Dont seal the grout, leave the grout alone for a month say, and only dry sweep the floor. Then when the initial grout has pretty well dried you could attempt another layer of the same grout. Then seal the grout.
