newly tiled bathroom, grout wrong colour! grout dye any good

[Curlyworld]

Just had new bathroom tiled and grouted. We have chosen the wrong grout colour and it looks wrong. Has anyone any advice on using grout dye? The grout we used is Microban 2, Gunmetal (lightish grey) and we should have used something darker.

Many thanks

No good for dying existing grout, it's normally added at the dry stage..

In your case either rake out the existing and start again, or learn to love it..

I regret using the too thick a tile spacer and light grout in bathroom, because have to keep mold under control

Yeah, it's not good when you spend time, money, stress getting tiling job done and doesn't look good because of bad choices. I have seen grout dye products on the internet that are intended to be used on old grout, or just to change the colour of new. Has anyone out there tried it out??

You will probably have to either leave it as it is or rake it out and do it again. You could try to use some sort of product to try to rectify the colour but if it doesn't work you might be left with patchy grout which wont look good at all. Try giving the grout a scrub when its completely dry, sometimes the dust from polishing off can make the grout look lighter than it really is. After you have done that use a grout sealer and protector, this can sometimes make the grout go slightly darker
