Chemical Resistant Epoxy 

1. Scope of Work 

1.1 The resinous flooring contractor shall furnish all labor, materials, tools and equipment necessary to install an Epoxy Systems’™ Product #15 resinous 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.

2.2.1 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.

2.2.2 Any hard troweled or old contaminated concrete areas shall be abrasive cleaned as necessary to insure that the concrete is free of all paint, sealers, curing agents, paint, 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 Asphalt. No application of epoxy resinous flooring shall be applied to asphalt substrate. Use EpoxySystems'  flooring material for these areas.

2.5 Wood. Plywood is acceptable as a substrate if proper care is taken to ensure that the panels are securely anchored and properly joint.

2.6 Ceramic/Quarry Tile.

2.7 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.

3.1.3 Chemical Resistance. The resinous flooring system shall be (or able to be made to be) resistant to spills and/or extended exposure as indicated from the following chemical for a period of up to 12 months: Distilled water, seawater, sulfuric acid 10%, hydrochloric acid 36%, hydrochloric vapor, sodium hydroxide 20%, diacetone alcohol, octanol, Xylene, toluene, skydrol, crude oil, gasoline 98 octane, citric acid 50%, fatty acid (linseed), lactic (dairy products), carbon tetrachloride, isopropyl alcohol, methyl isobutyl carbinol, mineral spirits, detergents anionic 2%, calcium hypochlorite 5%. Test method: sandblasted steel panels, coated with an average of 14 mil film thickness, immersed in the various material for up to one year.

3.1.4 Stain Resistance. The resinous flooring system shall be (or can be made to be) stain resistant to spills and/or extended exposure from the following chemical for periods of up to one year: butter, citrus juices, coffee, cola, grease, lard, lipstick, liquor, milk, mineral oil, mustard, vinegar (six months)

3.1.5 Flammability. Finished resinous flooring shall not support combustion and shall be self-extinguishing.

3.2 Color shall be , as specified by the architects. Pigments selected shall be compatible with the resinous flooring system.

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

3.4 Samples. Before installation begins, resinous flooring contractor shall provide 2 samples of each color for approval by the architect.

 

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 

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.

5.1.1 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 EpoxySystems' Product #3 injection resin (non-moving cracks) or EpoxySystems' 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.

5.1.2 In the event that the ENGINEER decides not to inject the cracks (if any exist), CONTRACTOR shall fill the cracks with an elastic jointing compound compatible with the resinous flooring system used.

5.2 Asphalt. See section 2.4 above.  

5.3 Wood. Plywood panels used shall be 3/4 inch (19 mm) exterior grade, securely anchored (glued and screwed) to the subsurface (e.g. studs 10-12" (4-5 cm) centers). They shall be free of excessive tool marks, gouges, and indentations. The edges of the panels shall be smooth, unchipped, flush to a line, and free of contamination (e.g.. glue used to secure panels to subsurface). Prior to the installation of resinous resurfacing system, the joints shall be filled with an elastic jointing compound compatible with the resinous flooring system used.

5.4 Steel. Steel substrates shall be free of rust, mill scale, grease, oil, or other contaminants and abrasively cleaned to "white metal" finish immediately prior to application of primer.

5.5 Ceramic/Quarry Tile. See section 2.6 above. 

5.6 Bond tests as recommended by the manufacturer of the resinous flooring system shall be conducted in order to assess the condition of the prepared substrate. No materials shall be applied without the consent of the resident Engineer. 

6. Installation:

6.1 Resinous flooring system shall be installed at a minimum depth of 1/8 in strict accordance with the manufacturer's installation instructions, by an applicator trained and approved by the manufacturer.

6.2 Primer: Apply a coat of primer if recommended by the manufacturer for the specific application at a rate recommended by the manufacturer. Any cracks in the concrete that exist at this time shall be evaluated by the ENGINEER.

6.3 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. The base cove (if any required) shall be installed so as to have a 1/2 inch radius at the bottom of it.

6.4 Base-coat: Apply a trowel coat of Epoxy Systems’™ Product #15 resin at a thickness so as to insure a total thickness of the system of not less than 1/8 inch.

6.5 Broadcast coat: Broadcast surface to saturation with an aggregate that is approved by the flooring manufacturer.

6.6 TopCoat: A top coating of EpoxySystems' Product #15, shall be applied in a manner and thickness as recommended by the manufacturer.
