    could also b wrong trowel size was used "to big" so addy coming out side of tiles not cleaned or set an grouted straight away causing change in colour is it just in the one area in corner or all over s/back.

    White metro brick tiles used
    Tub of ready made prostick acrylic adhesive used
    Ultra fine joint premium grade fine joint wall and floor grout used – not ready pre mixed

    Walls tiled prev…I striped them and prepared wall before new tiles
    Tiles were left 24hrs before grout

    Some areas are fine other areas are yellow/brownish

    How do I get it clean?????
