I have to replace three cracked 12" floor tiles.
The first step is to remove the grout around the tiles. The grout lines are
about 1/4" wide. I have a small manual scraper but it is slow and
laborious. Can I put a dry diamond blade in my circular saw and remove the
grout that way? Is there a better way?
Since they're "already" cracked, why not break them up some more with a
hammer/chisel and take 'em out that way? That way, you'll be able to
take most of the grout out since it'll be stuck to the broken pieces -
or it'll just break off - eliminating the step of "grinding" or sawing
out the grout lines. Doing it this way may also save you from damaging
surrounding tiles with your skill saw...
You are on the right track to remove the grout around the tiles you are
going to remove. I like to use a diamond blade in a angle grinder, but I am
sure you could use a circular saw.
I tried using a Dremel, which seemed to go thru the grout pretty well, but
couldn't get a good angle because of the cutting disk size. Now I'm
thinking my portable circular saw with a thin cutting disk would work well.
bit, but I assume you want to cut through the surrounding grout, not to
remove it all. The challenge when I used it was to cut deep enough but
not too deep. With your project, I would try to cut all way through the
surrounding grout so cracks do not extend into non-damaged area. The
Dremel grout bit uses a very small bit, but I suppose 4 or 5 passes
would eliminate a 1/4" grout joint.
