I need to remove the grout at the corners of the walls on our bathtub.
The original builder used grout and its now cracked, so we want to
remove it and replace it with caulk. Having never done this before,
we are wondering if there are any tricks to using a grout saw. I went
out and bought a grout saw, as well as a grout scraper(?) My husband
and I haven't tried anything yet...wondering if its going to be really
as labor intensive and it looks. Any advice would be greatly
Grout removal can be quite labor intensive. I have removed grout from tile
many times. I've used most of the gadgets made for this task. The best
gadget I've used (if the grout lines are wide enough) is the Dremel Tool
Go slowly with the bit. The bit breaks pretty easily if you don't keep it in
the groove. Wear a good quality dust mask and safety glasses. We run a
wet/dry vacuum with the nozzle next to the bit to carry off the dust.
As for grout saws, you will need one of those too. The saw is slow but works
ok. For both the grout saw and Dremel tool, patience is the key.
I hope this helps.
Just curious - since it's in the corner, have you considered just caulking *over* the
I've got the same problem in my house, and am trying to figure out how to deal with
Everything that I have read says that just caulking over the existing
grout shouldn't be done. Also, our builder did this in our Master
bath, which had the same problem and it looks horrible! (not to
mention that he did a really sloppy job). I guess is may also depend
on how bad the cracks are. The ones in our master bath were really
bad, and so we called our builder to fix them, even though they fell
under the umbrella of "settling" and technically weren't covered under
our builder's warranty. Because he did such a bad job, my husband
just wants to do the main bath ourselves ...and he wants to do it
right. I would be interested to hear if anyone else has tried
caulking over grout and if they got it to look good.
The best solution for controlled grout removal is to use the Fein
Multimaster with either carbide or diamond blades. It's not inexpensive
but it works very well and provides much more control than the Dremel
grout tool. One you own the Multimaster you'll find many uses for it.
Mine gets used weekly.
