•  The use of the machine and water must only be done by skilled workers that have been trained 

and understand the safety precautions that need to be undertaken. The danger of electric shock is 

present anytime water is used with electrical machinery. Water also presents the possibility that any 

floor openings or drains can serve as a conduit for water to damage unintended areas. The disposal 

of wet waste or slurry must be done in accordance with all local laws and regulations.

•  Upon starting the machine, continuously move the machine in a side-to-side pattern ensuring that 

the machine will grind the floor evenly. If for any reason the machine cannot be continuously moved, 

i.e. cord management, adjacent work, obstacles, etc., stop the machine until it can be operated as 

specified.

•  When cutting a new epoxy terrazzo floor, installation flatness will affect production greatly. The TPS 

#1 tool is specified as the “first cut” tool since it is the most aggressive in the system and designed 

to quickly remove floor stock. As such, any new floor must be ground to full aggregate exposure 

using the TPS #1 tools before commencing with subsequent steps. Being that subsequent steps 

are finer than #1, these tools cannot be expected to perform any more aggregate exposure; only to 

remove scratches from previous steps.

•  A thorough processing of the epoxy terrazzo can only be achieved by one pass forward and then 

second pass backward over same path. It is compulsory to overlap paths by at least 25%. The 

machine must always be swung side-to-side approximately 30 degrees. The machine should never 

be quickly pushed across floor to move to areas outside the area that is to be polished.

•  The work area must be closed to all non-associated workers and equipment. The likelihood of 

contamination by non-associated traffic is increased and rogue scratches will be possible as well as 

overall reduced polish.

Flooring Condition Qualifications

Use of the TPS Diamond System requires that the epoxy terrazzo floor is at least eight hours old. As 

a general rule, it is best to inspect floor BEFORE beginning to note or mark obstacles such as floor 

drains, protrusions from floor.
Any polishing project that is undertaken should ALWAYS be preceded by a mock-up of at least 100 SF 

/ 9 M

2

. This mock-up will serve two purposes: to provide a finished sample that owner can approve.
