I've got some grouting to do and its grey grout with white tiles, so it will show. My grouting has improved a lot now I know how to use the sponge properly - I did a small test panel and it looked good.
The grout is a cement-based one. If I grout in sections so one section has cured before I start the next, will it show where the sections join ? Or should I get organised and make sure I do it all in one hit ?
