Mapei Anthracite grout ruined Tiles

[Dumbo]

Maybe. Bit cant see with my eyes, unless grout brought them out. but heard a someone on here have the same problem in the past, also a couple reviews. I will be extra careful and inspect tiles individually next time.

As I said earlier pigment in grout got in scratches or as you say grout brought them out .

Your grout float can cause scratches too if it is in poor condition.

Those are scratches from something other than mapei grout.

I've just used 114 UCP on white glazed tiles without any problems. As above, I think that scratches were probably there but not noticeable until the grout was applied.

PS the tiles are level. However, the installation of the window is not!!!

I first read this thread just as I was finishing dinner earlier on today and just about to grout a bathroom floor with.........Mapie UCP in Anthracite!!!!
Needn't have worried.....done and dusted in 60mins, albeit on porcelain, but I have used the very same grout on Metros and not had a problem.

Hey, did you use a grout finisher?

I used one these.
TileMate Grout Float | Topps Tiles - http://www.toppstiles.co.uk/tprod42272/tilemate-grout-float.html

Pack of sponges (forget where from - screwfix sell the same) [EDIT - Three clean buckets of water ] and some automotive sprayers cotton cloth to remove the residue once dry.

Ok thats, I have that float. Thought people used a tool to smooth grout lines. That pen looking thing with a ball on top.
