I've got these massive 30cm x 60cm porcelain tiles in my bathroom and they look really good, only thing is the grout looks bad, it has changed colour and is patchy brown in places near bottom of wall. Floor is also porcelain 30cm x 30 cm and the grout used is the same as the wall and the grout effect here is worst. I finished the job about 6 months ago. As the floor is wood the grout needed to be flexible, so we used the recommended grout Ardu-Flex FS in white. How do I get this finished to look ok and is it possible to seal the grout after? Also, i left a haze of grout on the tiles which i though would come off but it hasn't!! any advise on this too would be great. thanks
