URGENT !! WTF tiles turning grey when applying grout???

[redchair]

Hi,

Just done the first section of grouting shower. Appears a grey border forming around the tile??? Think I'm going to remove the grout, its waaay darker than expected. I've got a bag of white to use. Any advice, the tiles are metros, can't be that bad and absorb that quick? Will post a photo.

grout 3000 natural grey. Going off very fast.

any advice is appreciated.

Removed the grout and cleaned out. Looks like grey bleeding into tile, bizarre and I'm not too happy about it.

I've got a bag of white Grout 3000 here, so long as I give it a few days for any remaining grout to cure, can I use the white? I grouted about an 8th of the overall area.

I had the same when applying white grout to really cheap white ceramic tiles, its almost of the tile was sucking in the moisture around the edges. I did make the grout a tad wet mind you so it might of been that or at least contributed to it.

Thanks. Yep, they were pretty cheap from CTD. The grout was pretty dry to be honest, mixed to instructions and at 20 degrees in the bathroom. Even then it was going off super quick.
I’ve removed all the grout and cleaned out the joints, You reckon I can just crack on with the white grout and leave the cleaned out area till last?

You might find the same happens with the white tbh.

No doubt I will

I'm guessing I likely panicked and it was a little moisture that would have dried out, but I wasn't to know!

The grout 3000 was a pain, started drying after a very short time. I'm going to use the Fugabella colour and promise my wife that I'll never tile again!
