Ron,

In respond to your questions regarding the blending of a newly honed and
polished floor with a floors that has been crystallized over a period of
time.

1. First thing you need to consider, the floor has been maintained for a
period of time only with crystallization, the floor will take on a yellow
look and is probably looking somewhat plastic. Also the floor will continue
to scratch and when they polish only with crystallization you get shinny
scratches.

When you went in a honed the floor you removed all the scratches, you
removed all the yellowed crystallization build up and therefore you have a
new clean looking floor.

2. The question I raise is why did you start with a 50 grit diamond? Where
there scratches in the floor lower than a 50 grit?  The biggest mistakes
made on floor restoration is most contractors start with too low of diamond
grit, when I ask the question why in most cases the reply is that the way we
were trained.In most cases it was a supplier of diamonds and chemical that
trained the person, not saying this is true in your case. But remember
suppliers are in business not so much to train you but to SELL you supplies.

In most cases the lowest grit you would need to start with would be a 120
even if there is a crystallization build up unless you had scratchesw below
a 50 grit.

3. My next question is unless the floor is black or green why would you hone
up to an 800?

In 90 % of floor restoration in lighter colors if you get a good hone and
sp0end the correct time honing you can stop at 400. Unless it's a black or
green floor.

In everything I just mentioned the key is the right diamonds and the right
polishing powders. My comments are based upon the use of StoneCare Central's
triple thick diamonds and the use of StoneCare Centrals 5X polishing
powders. ALL DIAMONDS AND POLISHING POWDERS ARE NOT CREATED EQUAL!

You must spend the proper time when honing and polishing, this is a concept
we teach at The Stone and Tile School, anyone that has attended the training
always comments on the system we train. This system teaches you the proper
timing for honing and polishing and is fail proof.

The next time you go to this property look at the area you honed and
polished compared it to the areas that are crystallized and you will see
shinny scratches and you will  see a yellow cast to the floor. So the long
and short is anytime you hone and polish an area it will look different.

If you are going to continue to maintain this floor with just
crystallization you will run into some problems. We also offer Maintenance
training that would help you with this problem.

If you have any questions, fee free to call.

Subject: [sccpartners] repair re-crystalize

Friends,

I have a small dilema.  We have a client with 28,000 sqft of marble
floors. Before we picked this account up the floors had been crystalized.
Do to the the expense of removing the crystalizer they decided to have us
maintain the floor in the same manner.

We were asked to remove some damage in the high traffic areas (around rec.
desk etc.) and here is where we have a question. After starting with 50
grit resins, and feathering up to 800, we polished with 5x - waited an
hour while working on another area, then re-crystalized.

The problem I need help with is the shadow between my repair and the old
crystalized surface.(it is only visible from 12-15 ft. away @ a certain
angle) I was not able to blend the area like I would with a polished floor
only. Is there any trick to blending crystalized areas? Also, the only
crystalizer we have used is from VMC and if someone can reccomend
something better- we are willing to try. Thanks in advance for your
suggestions.
