About this file
This is a technical specification section (096723) for resinous flooring systems required for the USDA National Center for Agricultural History Building 7 Suite 3 Floor Repair project. The specification calls for a Rock-Tred Polymer Coating Solutions SL System in Dark Grey with the following requirements: 50 mesh quartz traction material, UV-resistant urethane topcoat applied in two coats, a 4-inch integral cove base without traction material using troweled epoxy, and an overall system thickness of 1/8 inch. The flooring must be applied as a troweled screed and sanded finish to create a uniform, monolithic wearing surface.
The specification establishes stringent quality assurance and installation requirements, including engagement of an experienced installer certified by the resinous flooring manufacturer with a minimum of ten completed similar projects, procurement of all primary materials (primers, resins, hardening agents, grouting coats, and topcoats) from a single manufacturer with at least ten years of successful experience, and availability of manufacturer field technical service representatives during installation. Substrate preparation must achieve clean, dry, and neutral pH conditions with moisture-vapor-emission rates not exceeding 3 lb per 1,000 square feet in 24 hours. The contractor must maintain material and substrate temperatures between 65 and 85 degrees Fahrenheit during application and for at least 24 hours after application, close the work area to traffic for a minimum of 24 hours post-application, and provide a three-year warranty covering both materials and workmanship. All materials must be factory pre-weighed and pre-packaged to eliminate on-site mixing errors, and substitution requests must be submitted 10 days prior to bid date for contracting officer approval.

Maintenance Data: For resinous flooring to include in maintenance manuals.
QUALITY ASSURANCE
No request for substitution shall be considered that would change the generic type of floor system specified (i.e. 100% solids epoxy). Equivalent materials of other manufactures may be substituted only on approval of Contracting Officer. Request for substitution will only be considered only if submitted 10 days prior to bid date. Request will be subject to specification requirements described in this section.

Retain subparagraph above or below if available for products selected; see "Installer Qualifications" Article in the Evaluations. Retain below with requirements for Installer certificates in "Submittals" Article.
Engage an installer who is certified in writing by resinous flooring manufacturer as qualified to apply resinous flooring systems indicated.
Contractor shall have completed at least 10 projects of similar size and complexity.
Source Limitations: Obtain primary resinous flooring materials, including primers, resins, hardening agents, grouting coats, and topcoats, through one source from a single manufacturer, with not less than ten years of successful experience in manufacturing and installing principal materials described in this section. Provide secondary materials, including patching and fill material, joint sealant, and repair materials, of type and from source recommended by manufacturer of primary materials.
Manufacturer Field Technical Service Representatives: Resinous flooring manufacture shall retain the services of Field Technical Service Representatives who are trained specifically on installing the system to be used on the project.

EXECUTION
PREPARATION
Revise paragraph below to suit resinous flooring system selected. Some systems are moisture tolerant; consult manufacturers for guidance.
General: Prepare and clean substrates according to resinous flooring manufacturer's written instructions for substrate indicated. Provide clean, dry, and neutral Ph substrate for resinous flooring application.
Retain first paragraph and subparagraphs below for concrete substrates. Insert requirements for other substrates to suit Project.
Test above provides a more accurate indication as to whether or not a concrete slab has dried sufficiently to allow finish flooring application than the tests below.
For applying impermeable resinous flooring systems, 3 lb of water/1000 sq. ft. (1.36 kg of water/92.9 sq. m) of slab in 24 hours is generally considered a safe moisture-vapor-emission rate. Consult manufacturers for appropriate rates for permeable systems that will allow moisture vapor to continue through them once cured.
Some manufacturers use patching and fill material to fill control joints and other nonmoving cracks. Revise paragraph above or below to suit systems selected.
Treat control joints and other nonmoving substrate cracks to prevent cracks from reflecting through resinous flooring according to manufacturer's written recommendations.
APPLICATION
General: Apply components of resinous flooring system according to manufacturer's written instructions to produce a uniform, monolithic wearing surface of thickness indicated.
Coordinate application of components to provide optimum adhesion of resinous flooring system to substrate, and optimum intercoat adhesion.
Cure resinous flooring components according to manufacturer's written instructions. Prevent contamination during application and curing processes.
Delete subparagraph below if no expansion or isolation joints in floor. Detail joints on Drawings and revise below to suit Project.
At substrate expansion and isolation joints, provide joint in resinous flooring to comply with resinous flooring manufacturer's written recommendations.
Delete subparagraph below if joint sealant is specified in Division 07 Section "Joint Sealants."
Delete paragraph below if only self-priming systems are required.
With Owner's consent, retain paragraph below to ensure compliance with thickness requirements. Core sampling will require repairing damage caused by testing.
Delete paragraph and subparagraphs below if size or nature of Project does not warrant material sampling. If retaining, revise to suit Project.
CLEANING, PROTECTING, AND CURING
Cure resinous flooring materials in compliance with manufacturer's directions, taking care to prevent contamination during stages of application and prior to completion of curing process. Close area of application for a minimum of 24 hours.
Protect resinous flooring materials from damage and wear during construction operation. Where temporary covering is required for this purpose, comply with manufacturer's recommendations for protective materials and method of application. Contractor is responsible for protection and cleaning of surfaces after final coats.
Cleaning: Remove temporary covering and clean resinous flooring just prior to final inspection. Use cleaning materials and procedures recommended by resinous flooring manufacturer. Contractor is responsible for cleaning prior to inspection.
