• A thorough processing of the concrete can only be achieved by one pass forward and then a
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 EGT Diamond System requires that the surface to be treated is completely dry. For floors
that have adhesives, built-up contaminants or other coatings, the surface must be first prepared
using the #0 Prep Tool.
• Use of the EGT tools System can only be used, as specified above, for floors that are at least
4,250Psi/29Mpa and are over 28 days 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 and elevation changes in excess of 2mm.
• Any polishing project that is undertaken should ALWAYS be preceded by a mock-up of at least
100 SF / 9 M

. This mock-up will serve two purposes: to provide a finished sample that owner can
approve and to verify the suitability of the EGT Diamond System for the given slab.
Machinery Qualifications
The EGT Diamond System is designed to attach to and work perfectly with any Substrate Technology

Attachment of EGT tools #4 through #8 require Velcro pad adapters #570000031 & #570000026.
Densifier Qualifications
Manufacturer’s instructions for use must be followed exactly for best results and to avoid any costly
mistakes. Densifier must be the type that after its application, the floor is specified to be finished with a
dry system and no water whatsoever.

Polished Concrete - CLC Polishing System (Dry-Wet-Dry Steps)
The CLC Diamond System is a coordinated metal and resin bonded diamond system to perform
polished concrete using any of the eight models of P/M machines.
The CLC Diamond System is only to be used dry for step #1, wet for steps #2, #3 & #4 and dry for steps
#5, #6 & #7 and in sequence as numbered by tools #1 through #7. All tools are painted red or use red
Velcro to indicate a matched system.
CLC #1
1
CLC #1 is a metal bond tool painted red that has pictured face design and can be clearly
identified by the number on back as “#1.” This tool features the patented EG attachment
system. The tool is run dry. Approximate life of #1 is 30,000 SF / 2,787 M

CLC #2
2
#2 is a metal bond tool painted red that has pictured face design and can be clearly identified
by the number on back as “#2.” This tool features the patented EG attachment system. The
tool is run wet. Approximate life of #2 is 30,000 SF / 2,787 M
