Hiya.
2 years ago I decorated the bathroom and tiled a new shower area. I used Unibond waterproof grout. After some time the grout around the shower went a dirty pink colour.
Last weekend I decided to redo the grout, scraped it out as far as the clean stuff and redid it. Now after only a few days some of the lines are going pink again.
What's causing this? How can I stop it? Should I be protecting it with something?
Thanks a lot for any help.
