Grout 3000 leaching dye.

[Beyond the blue]

I've just used Tilemaster grout 3000 (natural grey) on the walls and floor of my own wetroom install. I left it for 3 days before sealing it and another 2 days before using it. After use it is leaching black dye quite badly, is this normal and will it eventually stop? I have asked Tilemaster for their opinion but not had a reply yet but hopefully they will.

Sounds similar to a problem that was had with bal ebony grout .
What are the tiles ?

Porcelain, polished on wall, mat on floor. The grout was streaking black while I was mixing it come to think of it, but it looked ok after giving it a good mixing.

I dont know grout 3000 says but did you mix by hand or with a whisk , did you use the correct amount of water ,

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

The reason i ask about the water is that bal problem was It dried to quick so want hydrated for long enough so every time it got wet it leached . Their answer was spray the joints with water then cover in plastic to keep them wet . Can't remember precise details .

Sounds like you ain’t mixed it correct, not long enough to mix the thingiemebobs right, so the thingimebobs leach out , if you get my meaning 🙂

I've used loads and loads of Natural grey 3000 (very good colour) and had zero issues with it.
At first thought it does sound like poor mixing but Tilemaster support their products well and I'm sure they'll help out.

Ok Ok! We know you don't like it! 🙂

 

[Andy Allen]

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

 

[Qwerty]

I did today. It was stressful but luckily I had been given the heads up. Would be a nightmare in the hot summer but I will mix up in smaller quantities

 

[Andy Allen]

What.....like an egg cup full...🙂

 

[Andy Allen]

Try it on Metro's...
Had a real sweat on getting the stuff off...

 

[Qwerty]

I can imagine. Mine were 400x150 ceramics and it was bad enough

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.

 

[Qwerty]

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

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!

Oh it's nippy setting for sure, I grouted a splashback with it, ceramics , about 3m at a time no issues ?

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