    Ive a problem with patchy grey grout,
    It was was done almost 3 months ago,
    Grouted after 10 days,
    It was a Weber.joint pro grout with additive ad250,
    Weber technical have suggested Lithofin cement remover.
    Has anyone used this product and did it work ?

    Don't rush in with the cement res remover, this may be simple washing surfactants left on the surface of your/ their grout, strange this took three months for them to get you back. You and weber dont do self cleaning floors or grout!! What were they maintaining with

    Is it patchy all over or in areas?

    It's patchy all over.
    The client has been using s steam mop on the floor.
    It's got got underfloor heating but it's still patchy on areas where there isn't any.
    I've been tiling 28yrs and never had this problem but saying that I don't normally use Weber grout.

    delta plus from kerrakol is good for this try not to over water grout or use to much water when washing off

    Had same patchiness with weber pro joint Jasmine not that long ago in a shower. 2 bits about 100-150mm long where the grout was lighter, typically the client liked the lighter colour and wanted it all the same. I hada bite my tongue but should have told her that her mates husband (plumber) should've wet all the joints when he tested his shower unit when he fitted it the next morning (sarcastic tone) lol. Or left it a few days until it was properly dry. I used that colour on the same floor with no problems. I was then dubious about weber pro joint but I've used it several times since and no problems.
