Product #899 Primer. This system shall be applied
over a clean, properly prepared substrate.
2. Prior to system application, all joints and cracks
are to be treated with a semi-flexible epoxy joint filler and rigid epoxy
crack filler respectively as described in the execution section.
3. The finished floor system shall be a minimum 65 mils
in thickness, dense, nonporous and test between 25,000 and 1,000,000 ohms
B. The rigid epoxy to be used for crack treatment
shall be Epoxy.com Product #720 or other epoxy approved by Manufacturer.
The semi-flexible epoxy to be used for control joint filler shall be
Epoxy.com Product #32
PART 3 - EXECUTION
Architect's approval of mock-up before installing Conductive Novolac Epoxy
Flooring System; see QUALITY ASSURANCE in PART 1.
B. Preparation of
1. Inspect surfaces
to receive Conductive Novolac Epoxy Flooring System and verify that
condition is smooth and free from conditions that will adversely affect
execution, permanence, or quality of work.
a. Remove all
projections, all debris detrimental to flooring system, and dirt, oil
contaminates, grease, and surface coatings affecting bond.
2. Notify Architect
in writing prior to commencing work of any conditions deemed unsatisfactory
for the installation; installation of flooring materials is understood as
acceptance of the substrate as satisfactory.
The General Contractor shall be responsible for hiring an independent
testing service to test for moisture content and moisture vapor emission
rate; install no flooring over concrete until the concrete has been cured
and is sufficiently dry to achieve permanent bond with flooring as
determined by material manufacturer's recommended bond and moisture tests.

Testing must be done to verify that the moisture vapor emission rate of the
slab does not exceed that as recommended by the manufacturer at time of
installation of the flooring or at any future date. Moisture vapor
emission and moisture content testing must conform with the requirements of
ASTM F-1869-98 (Calcium Chloride Test) and ASTM F-2170-02 (Relative Humidity
Probe Test). If test results show excessive levels of moisture content
or vapor emission rate, apply manufacturer’s recommended moisture vapor
emission control material.
