Hi guys
Ive been doing a job for a friend who owns his own construction business and he kindly let me tile the floor, and bathrooms on a new project he was doing himself. Anyway some stains have appeared along the joint lines on some tiles(not all, total floor about 20sm) ive put a pic up so you can see. The tiles were porcelain 600/600 from johnsons. The grout was norcross as well as the Adhesive. All supplied by the builder. I mentioned about sealing the tiles, but got told no need to. can someone tell me what it is and how to remove them if i can. . I do reckon they needed sealing though .
Also in the ensuite the grout has gone 2 colours. I've no idea what as caused this. Its the same bag, same mix, no contamination i know of.
Many Thanks
