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 Joint Filler.

PART 3 - EXECUTION

3.01      PREPARATION

A.         Obtain Architect's approval of mock-up before installing Conductive Novolac Epoxy Flooring System; see QUALITY ASSURANCE in PART 1.

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.

C.   Cracks and non-expansion joints shall be routed and filled with Epoxy.com Product #720 and Epoxy.com Product #32 Epoxy Joint Filler respectively.

3.02      APPLICATION

A.   General

Apply each component of the Conductive Novolac Epoxy Flooring System in compliance with manufacturer's installation instructions including mixing and application methods, recoat windows, cure times and environmental restrictions.  The system is to be applied directly over all non-expansion joints and cracks that have been treated as previously described.  Material applied over expansion or control joint material is subject to cracking due to movement in the joint.

B.   Cracks and Non-Expansion Joints

1.   Cracks less than 1/32" wide after surface preparation shall be filled with neat, rigid epoxy Product #720 or other resin approved by Manufacturer, mixed and applied as recommended by the manufacturer's printed instructions.  All treated cracks are to be sanded prior to applying primer.  Non-Expansion Joints shall be routed and filled with semi-flexible epoxy Product #32.

2.   Those cracks larger than 1/32" wide shall be routed and filled with rigid epoxy - Product #32. - or other resin approved by Manufacturer, mixed and applied as recommended by the manufacturer's printed instructions.

3.   Install cove using epoxy Product #720  as to the height and in the locations shown on the drawings.

C.   Epoxy Primer

Apply epoxy primer Epoxy Product #671 by squeegee and back roll at the rate of 250 square feet per gallon to thoroughly wet surface, but taking care not to "pond" the material.     

D.   Conductive Novolac Epoxy Body Coat Application

1.   Apply first coat of Epoxy.com Conductive Novolac Epoxy - Product #676 at a minimum thickness of 32 mils.  50 square feet per gallon is required coverage for 100% solids epoxy coating to achieve 32 mils thickness.

2.     Follow manufacturer's instructions for mixing and application techniques.  Allow to cure before applying second coat.

E.   Conductive Novolac Epoxy Top Coat Application

1.   Apply a second coat of Epoxy.com Conductive Novolac Epoxy - Product #676 at a minimum thickness of 32 mils.  50 square feet per gallon is required coverage for 100% solids epoxy coating to achieve additional 32 mils thickness (64 mils total thickness for the two coats). 

2.   Cure finish coat to manufacturer's recommendations.

3.   Conductivity testing must be performed by Installer and testing of point-to-point or point-to-ground must confirm proper conductivity range of 25,000 to 1,000,000 ohms.

F.   Obtain architect/engineer's approval of the system just after completion of the final coat, prior to completion of curing. 

3.03      CURING AND PROTECTION

A.   Cure Conductive Novolac Epoxy Flooring System materials in compliance with manufacturer's directions, taking care to prevent contamination during stages of the application and prior to completion of the curing process.
