Concrete Prep Diamond Tooling
Substrate Technology offers diamond tooling for any phase of the grinding or polishing process. Below
is a list of those tools and their applications. Please refer to STI's TDS (Technical Data Sheet) for details
of each procedure at www.substratetechnology.com.
1) #0 Prep Tool (leaves a smooth profile)
Description
The #0 Prep Tool is a metal bond preparation tool that has the EG attachment system as
a standard for use on any P/M Machines. Its uses are to remove adhesives, thin-sets,
surface inequalities of +/-4mm and epoxy coatings with thickness of less than 4mm. The
#0 Prep Tool is designed to be used as a dry removal tool only. The #0 Prep Tool is made
for use on concrete and should never be chosen to grind terrazzo, marble, or granite. The
concrete profile after using the #0 Prep Tool will be one that is consistently scratched and
resembles 80 grit sand paper. Approximate life of the #0 Prep Tool is 30,000 SF/2,787 M

Execution
1. Attach the #0 Prep tools to the Prep/Master
®
Machine and place it in operating position. Attach
appropriate power* and vacuum dust collection hose to the Prep/Master
®
machine.
2. With weights in neutral position** or off machine, start the machine and adjust speed to 45Hz (electric) or
2500 RPM (propane).
3. Upon starting the machine, continuously move machine in side-to-side pattern ensuring that machine
is 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
above. Upon satisfactory completion of surface prep, remove machine and vacuum surface clean.
* Power source Voltage will vary by P/M machine being used and should be verified for compatibility
before connecting machine to it. Dust collection by appropriate vacuum is compulsory as harmful and
damaging dust will be produced if dust collection is not used or is of inadequate capacity. The life of the
#0 Prep Tool will also be significantly reduced if vacuum is not of appropriate capacity.
**The Prep/Master
®
machines all have pocket weights for the purpose of varying the grinding pressure of
the machine. It is suggested to begin with the #0 Prep Tool with no added weight to gauge performance.
If the tool is not aggressive enough, simply add more weight to the grinding head of P/M Machine to
increase grinding pressure. If #0 Prep Tool is too aggressive, simply add more weight to the handle to
reduce grinding pressure.
Flooring Condition Qualifications
Use of the #0 Prep Tool requires that the surface to be treated is completely dry. For floors that have
adhesives or built-up contaminants, a scraping of the floor will improve performance but is not required.
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 4mm.
