Test the grout with your fingertips
Our expert says that one of the biggest mistakes
you can make on a grout job
is to start cleaning up the grout too soon.
Wiping the grout before it's hardened a
bit allows too much water to penetrate
the surface. That means blotchy-looking
grout or, worse, hairline cracking and
grout that falls out. To avoid these problems,
be sure the grout is very firm,
about like a wine cork, before you start
cleaning it. Press your fingertip into the
grout to test it. If it dents easily, wait.
