Jason,
You are in the right track. First strip off the wax / coating
that has been applied. Then if possible find out what grit the finish at from
the installer. Most installer will leave the terrazzo anywhere from a 80 grit
to a 120 grit.
Depending upon where the installer left the finish this will be
you starting point.
Apply the densifier after your 220 hone and then hone up to the customer
is looking for. High gloss is going to be 800 hone.
After you are finished then I would apply Stone Care Central
Solvent based Impregnation Sealer. I polished the concrete in my brother’s
trucking garages and after we polished the concrete then sealed with an the
Stone care Central Solvent sealer , that was 4 or 5 years ago and the garage is
auto scrubbed at least once weekly and it concrete looks great and is not stain
form the spills from diesel fuel, oils , grease etc.
So in this case I would recommend the solvent based sealer .

Subject: [sccpartners] Seal Exterior Cement Terrazzo?
It seems like this topic has come up before.....
Same job with 2k of exterior white cement terrazzo......
Keep this in mind...The terrazzo floor on this job cost the
owner $300K. The contractors put acrylic sealer on top everywhere, even outside
where it is exposed to the elements. It looked horrible. I still cant believe
they would put acrylic outside. Anyways, I have to strip it all off, run a grit
or two and densify. Should it be sealed? with an impregnator? My gut says no,
but the client is concerned with potential staining on a white floor. I
want the floor to breathe. Any topicals worth looking in to?
Thanks for your thoughts.
Jason
