Joint Filler.
PART 3 - EXECUTION
3.01 PREPARATION
A. Obtain
Architect's approval of mock-up before installing Conductive Novolac Epoxy
Flooring System; see
B. Preparation of
Surface:
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.
3. Concrete:
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.
a. Effectively
remove concrete laitance by steel shot blasting or other method approved by
flooring manufacturer. Achieve minimum surface profile of CSP-3.
b. Concrete slab
shall have an efficient puncture-resistant reinforced moisture vapor barrier
10-15 mils thick minimum directly under the concrete slab (for slab on
grade). Do not use vapor barrier manufactured with recycled material.
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.
