Part 1

Scope of Work
This work consists of furnishing all labor, materials, tools, equipment, and service necessary to satisfactorily complete the installation of composite rubber flooring plank shown on drawings or in finish schedule.

Performance Requirements
Resistance to Dynamic or Rolling Loads

Care must be taken to prevent damage to composite rubber flooring by wheeled vehicles and furniture or appliances with casters. To reduce rolling resistance and minimize risk of cutting, indenting, or grooving the rubber flooring, the proper wheels and casters should be selected to carry a load of not more than 150 pounds per square inch (10.6kg per cm2). Since rollers, casters, and wheels on furniture and appliances may damage resilient flooring, any warranty as to their suitability lies with the furniture or appliance manufacturer.

Static Loading
Floor protectors should be chosen so that stationary loads do not exceed 150 pounds per square inch (10.6kg/cm2).

Flexibility
At room temperature, the rubber flooring shall bend around a 3/4″ (19 mm) mandrel without breaking, crazing, cracking, or showing any change in color.

Certifications
Composite Rubber Flooring Planks meet California Section 01350 and contain no ozone-depleting chemicals (ODCs), plasticizers, halogens, PVCs, or organochlorides nor are they produced using ODC containing materials.

99.99% reduction in surface antimicrobial activity (S. aureus & E. coli per ISO 22196)

Environmental Conditions
The room and material temperature should be 70°F (21°C) 48 hours prior to, during and after installation. (“Temporary” HVAC is not acceptable. Systems should be fully functional and in operation prior to any resilient flooring installation.) The sub-floors which are to receive composite rubber plank flooring shall be smooth, clean, and dry and shall be inspected, approved, and accepted as satisfactory by the subcontractor for resilient flooring before installing this material. (If to be installed over a wood sub-floor treated with fire retardants or a metal sub-floor, contact us for recommendations.)

For on-grade installations where there is a possibility of moisture being present, it is recommended that SRP Industries #95 HydroLock or #5 Epoxy Flooring Adhesive be used. Moisture transmission should not exceed three pounds per thousand square feet per twenty-four hours.

Where excessive moisture exists, we do not recommend the installation of our MoreFlor Composite Rubber Flooring Planks. We do not recommend exterior installation or over existing floor coverings


Part 2
A. MoreFlor® Composite Rubber Flooring Planks as herein specified or shown on the drawings shall be 1/8″(3.2mm) gauge as manufactured by SRP Industries of Akron, Ohio. Composite Rubber Flooring Planks shall be first quality in standard 6” widths by 48″ lengths, fully homogeneous and uniform through the plank, and comply with the requirements of ASTM F1344 and shall contain no asbestos fibers. Boxes shall contain 15 planks or 30sqft.

Finishes / Colors
The coloring matter shall be of good quality, insoluble in water, and resistant to alkali, cleaning agents and light. MoreFlor Composite Rubber Flooring Planks are similar to products of nature and therefore will have variations in color and tone.


Part 3

Preparation of New Concrete Sub-Floors
Prepare concrete in accordance with ASTM F710. Concrete should be troweled to a smooth, even surface and be aged for at least 90 days. Expansion joints should be properly filled. Neutralize the surface of the concrete. Use either 1 part Muriatic Acid and 9 parts water or 1 part white vinegar and 5 parts water to make a good neutralizing agent. Solution should remain on floor for at least one hour then flushed thoroughly with water. Allow to dry thoroughly (minimum 48 hours at 70°F). Concrete should be sound, hard and free from scale or other imperfections and thoroughly dry when installation is made. CAUTION; cinder fill, vermiculite, pumice, and other aggregates, which are hygroscopic in nature, cause the concrete to be very slow drying. This type of concrete will easily absorb excessive moisture from the atmosphere and other sources. Any concrete curing compound must be completely removed.

Preparation of Wood Sub-Floors
A solid core, exterior grade plywood with one side sanded is recommended. Lauan, Particle Board, Chip Board or Hard Board should only be used as underlayment if absolutley level and smooth. Be sure wood sub-floor is thoroughly nailed or otherwise securely fastened to the substrate. If the wood sub-floor is uneven, it should be sanded smooth. The dust from the sanding operation should be removed by vacuuming. It is recommended that floor patching or leveling compounds are to be non-gypsum based.

General Installation Considerations
Just prior to the installation the sub-floor should be broom swept or vacuumed and damp mopped and allowed to dry. MoreFlor Composite Rubber Flooring Planks shall be installed in a neat and professional manner with clean tight seams/joints, and with an adhesive appropriate for the installation. For most installations, SRP Industries #56 Latex Adhesive is appropriate. When concrete moisture is of concern, SRP Industries #95 HydroLock Adhesive is recommended for installations up to 90% Relative Humidity.

It is recommended that all flooring planks be dry laid and inspected to detect any possible abnormalities before beginning installation. Immediately after installation, the planks shall be thoroughly rolled in both directions with a 150 pound (68kg) sectional rolle

This adhesive must be used throughout hospital operating suites. Contact manufacturer for more information on recommended adhesives and their use.

3.04 INSTALLATION

           General:

           Install rubber flooring in a neat and professional manner with tight seams or joints, and with an adhesive appropriate for the installation.

For most installations, use flooring manufacturer’s recommended #56 Latex Adhesive.

           First dry lay all flooring materials and inspect to detect any possible abnormalities before beginning installation.

           On rolling equipment, use flat wheels with no ridges to avoid floor damage.

           Immediately after installation, thoroughly roll rubber flooring in both directions with a 100 – 150 lb (46 – 68 kg) sectional roller. Apply weight to seams as necessary until a suitable bond has been established.

           MoreFlor Composite Rubber Flooring Installation:

           Dry lay all planks and cut to fit as necessary.

           Spread adhesive in the field areas.

           Place rubber plank flooring into adhesive and roll with a 100 – 150 lb (46 – 68 kg) roller. Ensure proper bonding by using a hand roller at the seams to force adhesive into seam and create a chemical bond. Weight seams as necessary until a suitable bond has been established.

  • Let dry for 48 hours before allowing traffic on floor.

3.05 REPAIR/RESTORATION

After removing plank from the section to be repaired, follow instructions listed above in section 3.04 Installation to replace.

Specifier Note: Specify the tests and inspections required for installed or completed work. Retain edit or delete article below to suit project requirements and specifier practice. Calcium chloride test should be conducted for all concrete substrate and concrete pan stair tread applications.

3.06 FIELD QUALITY CONTROL

           Site Tests: Conduct calcium chloride moisture test in compliance with ASTM F1869.

           Maximum allowable moisture transmission must not exceed 3 lb/1000 ft2 in 24 hours.

Specifier Note: Specify the final actions required to clean installed equipment or other completed work to properly function or perform. Coordinate article below with Division 1 Execution Requirements (Cleaning) Section.

3.07 CLEANING

    1. NO APPLIED FINISHES OR SEALERS ARE REQUIRED. It is recommended that no floor finishes or sealers be used on MoreFlor. Gloss level will depend on the frequency of buffing.
    2. STEP 1: Stripping as Needed – MoreFlor should be thoroughly machine stripped and scrubbed with a scrubbing pad and stripper. Use stripper manufacturer’s recommended stripping procedure. General Cleaning – Clean floor thoroughly with a good grade of mild detergent cleaner. Use manufacturer’s recommended cleaning procedure.
    3. STEP 2: Neutralize stripper or cleaner with minimum 10% solution of liquid chlorine bleach. Vacuum, mop or squeegee the neutralized solution from the floors. Rinse the floor surface with a solution of 10% liquid chlorine bleach in warm water (may need two or more rinses).
    4. STEP 3: Once the floor is dry, buff floor using an Ultra High Speed Buffer with a red pad. (A light mist of clear water ahead of buffer often helps to develop sheen) After sheen is developed, a higher gloss may be obtained by using a white super polishing pad. Note: After initial buffing, MoreFlor can be spot cleaned.
    5. STEP 4: Dry dust or mop floors. Do not use dusters or mops treated with mineral oil or other petroleum products.
    6. STEP 5: Periodically mop floors using 5% solution of liquid chlorine bleach in water or comparable disinfectant.
    7. ALL ABOVE STEPS TO BE USED AS NEEDED.
