honing horrors Baird Standish 11 Jun 2009 20:50 EDT
We've had a project this week that has sent us back to the drawing
board. Any advice would be most welcome.

We took on a job to hone a very light /white (when dry) limestone
floor. The floor is about seven years old and the new owner wanted us
to re-hone the floor imparting some gloss.  The floor was pretty
dinged up.  We have had success with honing marble to 400 or 800 grit
with twister or velocity pads, so in this case we honed up to 800 grit
with the velocity pad (we tried some honing powder but it left it
pretty dull).  We got a pretty good gloss but the floor started
showing every minor track mark, swirl, and other side-by-side zigzags
leaving a very inconsistent look.  Also, we found it nearly impossible
to get up all the residue.  We then put the twister pad on a
burnisher, which gave it more gloss and a more even look but still we
could see the burnishing pattern and residue still wouldn't come out.
We tried wet and dry.  We then put some MB-8 on the floor, which
helped, but not much, and the more gloss we got the more minor
imperfections were easily seen.  The floor itself gets a lot of
sunlight and is is not perfectly flat, so waves in the floor could
also be seen. Also the MB-8 didn't go down as easily as on a polished
floor.  The long and short of it is that we gook all of the poly off
by wet honing the floor with an 800 grit twister pad. The floor now is
completely smooth and clean with no imperfections but also very matte
in appearance with no gloss.   I suggested to the owner that he
either  go with the flat look or take the plunge and have us powder
polish the floor.  But I really would like to keep to a honed finish
with  a little gloss (similar to the way it was before).  Just can't
get away from  the track mark/ residue issue.   Here' are some picures
of the floor before we started.  Any help would be much appreciated.
