A few years ago, I had ceramic tile installed in my house. In several places
the grout is cracking where it meets the baseboards (it's fine everywhere
else). I have tried regrouting those areas but they crack again. One
solution I thought of it to find a caulk that's close in color to that of
the grout and put the caulk in the cracks, being careful not to overdo it.
But first I'd like to ask if anyone has other ideas. I realize that the
ideal way to install the tile would have been to remove the baseboards first
and then put the baseboards back on top of the tile, but that isn't how it
was done. Thanks.
Perhaps you can add more water to the grout, make it more liquid and
pour it on to fill these few areas.

Silicone caulk is probably the way to go. It sounds as if you already
know caulking ain't as easy as it looks on tv. You might *drag* a
credit card-sized piece of plastic dipped in water from the corners
inward to smooth and remove any excess, followed by a wet finger,
followed by a damp rag, followed by a wet finger, until you achieve
the desired result.
Less is more, as long as the joint is filled.
If all the cracks are close to the baseboard, I'd caulk them. Don't try a
touch-up job ... caulk that joint continuously.
1/ Use a color that is as close to the grout as you can find.
2/ Use water-base caulk.
3/ Wet the joint with a damp rag, before caulking.
4/ Trim the joint with a wet finger after caulking.
5/ Wipe the joint with a wet rag as a last step.
Practice on one section. You can easily remove it with a wet rag and start
over. If you are not good at these kinds of tasks, hire a handyman.
I don't guess you know what brand of grout you have. The grout in my
new house has color matched caulks. Go on line and look.
I recommend you use a silicon based caulk, not 100% silicone. Regular
caulk is porous and will stain after a couple years, the color will
change as the dirt gets impregnated in it. If you can get a good
steady run going with the caulk gun, don't even use your finger to
smooth it out. Leave the pretty little bead there. A bead of caulk
will rarely crack whereas when you smooth it out to a flat or concave
surface, it will have more of a tendency to crack, especially if its
The grout is not going to stick to the baseboard. I have the same
problem in my shower. It has very nice shiny large tiles and they
grouted the bottom where the fiberglas base and the tile meet, it's
already cracking after 1 year. I will be shopping for the caulk
The area where my bathtub and ceramic tile meets have the same issue.
We just opted to use clear silicone. Due to the weight of the water
causing the tub to shift/expand a small crack does form at that joint.
But I can clearly see the silicone coating is completely intact.
Leaves me with some peace of mind.
I doubt you will be able to keep grout that is touching the baseboard
from cracking. And I sure would not slap caulk on top of grout. We had
baseboards and trim undercut prior to installing our 3 rooms of tile.
When tiling was all done, I put paintable caulk around the joint,
masking very carefully to keep caulk from oozing under the tape and onto
the grout. You might be able to use a grout bit or small grinder the
clean out the joint up to the baseboard, then caulk and repaint the
