Hi all

Has anyone tried these "grouting renovation" products you see in the
sheds? They look expensive and very fiddly to me; I'd be prepared to
put up with both, if the end result is as good as they say, but it's
better to get some opinions first if I can.

The one I tried was just like an acrylic paint sitting on top and rubs off
very easily when wet. Neat thick bleach left overnight and scrubbed in with
a hard brush can be quite effective.
