Stuart,
The KEK has terrible odors, some of the other products I would
suggest would be low odor mineral spirits , this works well on removing oil
stains, peroxide 30 to 40% volume works well on stains that are non metal or
organic staining. Alkaline base strippers also work well when removing
oil and grease stains.
In this case if you think someone has already ground the surface
then what you may be seeing are the areas the finish does not match the rest of
the finish on the stone. I don’t think this is the case.
I had a similar problem about 10 years ago and the
only way we were able to correct the problem was to hone the entire floor. I think
Dr Fred may recall this job it was in the home of a professional golfer and
honing was the only answer.
When mixing the chemicals I found that DE powder works the best,
however I have instructed customers on to remove stains using household
baking flour. You can actually use white paper towels , terry cloth towels etc.
All of these will work. The secret to removing stains is to be
good at determining what type of stain it is and using the proper chemical and allowing
the poultice to totally dry before removing it.
Keep in mind that removing a stain is like removing an infection
from a cut. You put on the right medicine for the infection place a band aid
over the cut and the infection is pulled into the gauze, the powders etc acts
as the gauze and if the poultice is not left on long enough the stain will not
be pulled into the powders and the stain will not be removed.
In some cases the stained area may require you to first open the
stained area with a 120 grit diamond to allow the poultice to penetrate the
stain.

Subject: [sccpartners] Strap marks
Last week, I posted a message about these strap marks.
I actually got to see the floor this morning. The stone is a Jerusalem stone
(limestone?). Over an 800 sq ft area, I saw these strap marks on fifty
tiles. The strap marks are dark in hue, not reddish, so I'm led to
believe it is not rust, but I don't know Someone has already tried to
grind the straps off , to no avail. So, my idea is to poultice these
tiles. Tomorrow I will set a poultice on one of these stones as a test. I
have had very little success using a poultice. However, a friend of mine
who works on granite counter tops successfully removed stains from a countertop
last week using a mixture of MEK and sheetrock powder. So I'm going to
use this mixture on the Jerusalem stone. Does anyone have any suggestions
on other liquids I may use in a poultice to remove these strap marks?

Georgie,
A very good white granite to use for monumental stone is
Bethel White. It is used for exterior applications quite often and is
quarried in monument style and thickness. Your local monument dealer
should be able to source that for you. AS far as puppy paw imprints, yes
it can be done. There are CNC machines which have a router / carving
function built into the programming. The question becomes whether or not
the shop has the tooling for that application. When you order the
monument you should be able to find out if this shape carving (called flat
carving in the monument industry) is available from the quarry
location. They will typically do this on the stone and then the stone
blank to the momument dealer who will letter it and install it. I know
this is available from Cold Spring granite company in Minnesota and they quarry
Bethel White also.

Happy 2010 all!
I have a question regarding the selection of granite. I have a friend who
recently lost her husband and she was thinking of getting white granite for his
head stone. Am I correct in thinking that white Granite will etch faster
than other granites? Or can you make a suggestion for selecting a granite
that will last longer?
Also, her husband truly loved his dog and she was wondering if it is possible
to make a cast print of the dog's paw and then fabricate a stone piece to the
shape of the paw to place on his headstone. Is there a way to do
this? Not really important, but I was wondering myself.
Thanks all and enjoy 2010. It is going to be a great year and decade.
