Grout 3000 leaching dye.

[Beyond the blue]

Also did you mix twice? I used Grout 3000 charcoal today with no issues

Mixed it well bearing in mind it goes off so quickly. You say you used it "today" with no issues but my problem was days later, hope yours is OK.

Only time will tell but I very much doubt it. I had no colour issues when mixing. Everything was uniform and as it should be.

Did you use a mechanical mixer to knock it up?
Any photos of your issue as I'm sure @Glynn (Tilemaster) would like to try and help

Did you use the correct amount of water

 

[Dumbo]

That's an understatement...
Have any of you used it on ceramics, just ridiculous the speed it goes off...

Have you used mapei ff on ceramics that's a slow grout , I know because it suits my working practices

Just had this reply from Tilemaster

Thank you for your email.


I have known this happen a few times with grouts, not only Grout 3000 but products made by other manufacturers. Essentially all it is, is some loose laitance / contaminant left on the face of the grout that wasn't removed during the washing off phase. As the running water hits the face of the grout, the loose particles run off with the water. This will certainly stop once the contaminants on the surface have either been fully removed by the water, or equally if you were to rub along the joints with a slightly coarse pad, such as a washing up sponge, this will remove the very slight film left on the surface of the grout.

We shall see what we shall see!

Love the new 3000. Can use it on floors now.the older 3000 took too long to go off in my opinon
