Stu,
I always approach epoxy terrazzo the same as cement based
terrazzo. In most cases the terrazzo installer diamond grinds the floor up to 80
to 120 grit. In many cases they are using diamond plug in their equipment. These
diamond are usually most aggressive than the diamond we use in the restoration
business.
The process I use on terrazzo both cement based and epoxy are
listed below.
1.
If floor is coated with a wax or terrazzo sealer I strip the floor
using a goo d alkaline based stripper.
2.
If the floor has never been in a natural polished condition, I start
with a 50 grit resin diamond, this will guarantee to remove any scratch
patterns left behind from the installers.
3.
I continue to hone up to 400 or 800 depending upon the color of
the terrazzo. If the terrazzo is a light color I stop at 400, if the stone is
black or green or dark colors I stop at 800
4.
I then polish the floor with 5X polishing powders
5.
Then depending upon the finish I want I may do light application
of crystallization ( which is an approved method of polishing from the Terrazzo
Institute )
on cement based terrazzo you can do another process.
1.
Strip the floor if necessary.
2.
Diamond grind from 50 to 220
3.
Apply a concrete densifier pour on terrazzo and gkeep the
surface wet for 45 minutes, then vac off the excess.
4.
Apply a thin application of the densifer using a finish mop , do
not leave any excess on the surface.
5.
Allow the mopped on densifier over night
6.
Hone 400,800
7.
Then crystallize the finish the floor and the cement will both
polish and the shine and finish will be outstanding

Hi All,
Have to do a epoxy terrazzo job next week. Curious as to
what are some of the techniques used by others.
We find a starting point with diamonds and go wet to 3500g
on our lavina, clean it up and call it a day( or in some cases a couple of
days!)
Any info would be great.
