Malei Grout has dried in different colours

[Renovating101]

Hello,

We are first time tilers, we finished laying the tiles last weekend and grouted them yesterday.

It is laid onto a sand and cement screen base which was laid around six months ago. We used 900 x 150 porcelain tiles and a mapai flexible adhesive. The room has never been used and is newly built so doesn’t have any damp or condensation problems.

we grouted it using Mapei grey flexible grout, followed mixing instructions/water ratio/electric mixing paddle and the grout has dried almost white in places but darker elsewhere. I’ve attached photos to try and show the colour difference (please be kind as we aren’t professional tilers)

We like the darker colour but the paler doesn’t look how we hoped. Is there any way of darkening it up without having to scrape it all out? The room is 27 square metres so there are a lot of grout lines.

that’s likely what I did then, I’ve seen mapai do a grout refresher/colour called fuga fresco. Does anyone have experience of this and is it likely to be suitable to darken it up?

I'd give it an acid based wash, try it in a out of the way area first.

I've used the fuga fresca white. It's very good. Inexpensive and worth a try.

Update: we used the fuga fresco and painted on with a tiny child’s paintbrush and really happy with the final result.

I mop the floor daily and after a couple of months the colour has remained consistent.
