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

If you need additional information , please advise

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.
