Roger,
My experience with honing powders has not been a problem. The key
when using honing powders, polishing powders, or any powders is to make sure
you are flushing the grout lines once you have finished the honing process.
By flushing the line what I mean is once you have finished a
section of floor run over that area again with more water and the honing
powders should flush out of the grout lines.
What most people do that gets them in trouble is they try to do
too large of any area before cleaning up and the honing powders and the slurry
start to dry in the grout lines this causing a problem.
I also recommend when ever using a powder that you have with you
a soft scrub brush, grout brush on a handle and lightly scrub the grout line
before vacuuming up the water and slurry / honing powders etc. this will remove
the excess powders and slurry etc. from the grout lines and actually help clean
the grout.
My suggestions is to control the size of the area you are
working in and make sure the slurry etc does not start to dry before you start
to vac it up.

lighter grout can be from
honing powder residue or it can that the grout is discolored. There is
not a lot you can do if that is the original color.

…….. Just did 2000 sq ft of tumbled unfiled travertine color is
perfect ! You should see the installers here, what a joke! I’m
re-grouting 200 sq ft now, the installer used a bag of grout the customer had
stored in her garage for 12 years. I asked the installer why he used a 12 year
old bag of grout with a shelf Life of 2 years or less. He replied
“it’s just grout, It’s not like you’re going to eat
it.” The customer suggested he use it, and return the bag he bought to
save money.

Not much, grout has
to be mixed extra properly.
If you open a bag of
grout and look at its contents along with the cement you will see little tiny
colored clusters. That’s the powdered dies they use. It’s not
totally mixed so unless the installer mixes an entire bag at a time, you cannot
get a consistent color.
Now imagine applying
grout for the first time on limestone installation, it dries so fast there is
almost no way they can pull a full bag unless they have an assembly type of
system where one guy applies , one guy cleans and another follows. I have
rarely seen this! Now imagine a larger area, you are suppose to dry mix
all the bags together as well.
Most mix a small
amount at a time. Also if the installer doesn’t use the exact same
amount of water, coloration will further be affected.
And when you clean
up the grout residue during installation, you should clean it using a
consistent amount of water on the sponge as well as keeping the water
clean. What they are asking to do is never done especially during a
commercial job, so it’s almost normal to get shades of whatever color
they used.
Below is a few lines
of what is written on a bag of grout
2.1
For best results, have the same person mix all of the grout.
Consistent
mixing and cleaning techniques will promote
more
uniform results.
2.2
Before mixing the grout with water, dry-blend the product
to
avoid color variations in the finished grout, which may
arise
from pigment settling during shipment. If two or more
cartons
or bags are to be used, dry-blend all the contents
together.
5.5
To prevent discoloration and soft or powdery joints, avoid
cleaning
with excessive water.

With a lot of limestone in homes or other
honed surfaces, we frequently use honing powders. No matter how thorough we
are in cleaning the grout lines, some always end up with some grout lighter
or different color from the rest of grout. Why is this? What can be
done to prevent or correct this problem? Thanks, RK |
