Section 09702

EXTREMELY HIGH CHEMICAL RESISTANT FLOORING SPECIFICATION - Novolac Epoxy

 

1. Scope of Work

1.1 The resinous flooring contractor shall furnish all labor, materials, tools and equipment necessary to install an Epoxy.com Extremely High Chemical Resistance Novolac Epoxy Flooring in such areas as indicated on the drawing and/or specifications.

2. Related Work Specified Elsewhere

2.1 Resinous flooring material provides an impermeable barrier against rising moisture. All Substrates must therefore be free of ground water effects and verified as such prior to installation of system.

2.2 Concrete. The concrete on which a resinous flooring is to be installed shall have a minimum compressive strength of 3000 p.s.i and shall have cured at least 28 days before installation begins. New concrete shall be straight properly sloped, and finished with a fine broom, or wooden float. Extra care shall be taken not to raise any unnecessary "cream" to the surface. Concrete in these areas shall be moist cured with burlap or polyethylene. No chemical curing agents shall be used. Use no methods or materials that would prevent the proper bonding of an epoxy material.

Any hard troweled, old contaminated concrete, or previously coated areas shall be abrasive cleaned. This abrasive cleaning shall be blast cleaned, Dust Free Ground (or other method approved by the ENGINEER) as necessary to insure that the concrete is free of all paint, sealers, curing agents, oil, grease, moisture, dirt and other contaminants.

2.3 Steel. Steel substrate shall be sandblasted prior to the installation of the resinous flooring system. All surfaces shall be primed with an appropriate primer as supplied by the manufacturer of the resinous flooring system. These surfaces shall be primed the same day or before there is any visible signs of oxidation, whichever is sooner.

2.4 Facilities. The resinous flooring contractor shall be provided with dry storage space for materials and equipment and with suitable electric current at no charge for the processing tools and mixing devices running on electricity.

3. Materials

3.1 Resinous flooring material shall be Epoxy.com Extremely High Chemical Resistance Novolac Epoxy Flooring consisting of Epoxy.com  base-coat of Epoxy.com Novolac Epoxy Mortar Resin, and a neat coating Epoxy.com Novolac Epoxy Mortar Resin as a top-coating. These products are manufactured by Epoxy.com a division of Epoxy Systems, Inc. of Florida and Vermont. Material shall also include appropriate select fillers. Resinous flooring material to be in accordance with manufacturer's recommendations. Epoxy.com Extremely High Chemical Resistance Novolac Epoxy Flooring is a 100% solid, Novolac Epoxy resin.

3.2 Type and gradation of fillers used shall be those recommended by the manufacture of resinous flooring resin.

 

4. Acceptance of Substrate

4.1 Before installing any resinous flooring system, the applicator shall inspect the substrate and immediately report to the general contractor, architect, or owner any unsatisfactory conditions.

 

5. Preparation of Substrate

5.1 Concrete. The concrete surface which is to receive the resinous flooring system must be dry, clean, and free from contamination. Any loose or corroded segments of existing concrete shall be removed and the area patched with a grouting compound as described and supplied by the manufacturer of the resinous flooring system. Any sealant or release agent on existing concrete surfaces shall be removed by mechanical means.

Any cracks in the concrete shall be evaluated by the ENGINEER. In the event that the ENGINEER decides that it is cost effective and necessary, all cracks (if any exist) shall be injected by Epoxy.com Product #3   or Product #310injection resin (non-moving cracks) or Epoxy.com Product #4 flexible chemical grout (moving cracks), depending on whether the Engineer determines the cracks to be moving or non-moving cracks. The cost, and specifications of these repairs (if necessary) will not be part of this section, but shall be handled under section of this specification.

In the event that the ENGINEER decides not to inject the cracks (if any exist), CONTRACTOR shall fill the cracks with Epoxy.com Product 11.

6. Installation:

6.1 Resinous flooring system shall be installed in strict accordance with the manufacturer's installation instructions, by an applicator trained and approved by Epoxy.com Technical Support Department.

6.2 Base Cove: A base cove of 4 inches high will be applied to all wall surfaces where noted in this section or on the drawings.

6.3 Base-coat: Apply a coat of resin at a thickness so as to insure a total thickness of the system of not less than c inch, or in the case of a patch to thickness of existing flooring.

6.4 Top-Coat: A top coating of Epoxy.com Novolac Epoxy Resin, shall be applied in a manner and thickness as recommended by the manufacturer.
