was their wallpaper on walls proir to fixing?was it stripped? what addy an grout was used? was it the all in one tubbed addy an grout? where tiles left to set before grouting 24hrs? what tiles is it? had one like this a while back..tiler fixed tiles ontop of wallpaper whole grout area turned yellow 16m2..
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?????
