PART 3 – RESPONSIBILITES
3.01
GENERAL CONTRACTOR RESPONSIBILITIES
Note: In the absence of a general contractor, these responsibilities defer to the end user.
A.
Supply a safe, climate controlled building and subfloor as detailed in the nora Installation Guide (available at
www.nora.com/us).
B.
1. A concrete subfloor that meets the requirements of ASTM F710 Standard Practice for Preparing Concrete Floors to
Receive Resilient Flooring is required, or as detailed in the nora Installation Guide.
2. A wooden substrate that is not directly in contact with concrete or soil subfloors on or below grade, even if built on sleepers
is required. All suspended wood floors should have an adequate underfloor ventilation system, and a permanently effective
vapor retarder should be placed on the ground beneath the air space.
C.
A concrete subfloor that is structurally sound, and has finished shrinking, cracking, curling or moving in any way is required.
D.
For all concrete substrates on or below grade, a permanent effective vapor retarder with a low permeance (less than 0.1) and
that meets the requirements of the latest edition of ASTM E1745 Standard Specification for Water Vapor Retarders Used in
Contact with Soil or Granular Fill under Concrete Slabs, should be placed directly underneath the concrete above the granular
fill, and installed as per the manufacturer’s written instructions. Alternatively a surface applied moisture mitigation system
should be used as described in 3.01 H.
E.
A clean non-burnished concrete surface free from any paint, wax, oil, grease, and film forming curing compounds, silicate
penetrating curing compounds, sealing, hardening or parting compounds is required. The surface should not have any alkaline
salts, laitance, mold, mildew, residual adhesive, chemical adhesive removers or anything that may prevent appropriate
products bonding to it. If not then the general contractor should provide the mechanical means to remove them. This could be
dustless diamond grinding (DiamaBrush), bead-blast or similar with a suitable Hepa vacuum attachment. Review and comply
with all relevant local, state and federal regulations.
F.
Valid tests and acceptable test results should be provided to the end user and flooring contractor, including documenting with
photographs, the location of all tests, recorded % relative humidity levels and temperature of both the concrete subfloor and
ambient conditions prior to flooring installation. Testing should be performed at the correct, controlled ambient service
temperature and humidity following the protocol of ASTM F2170 Standard Test Method for Determining Relative Humidity in
Concrete Floor Slabs Using in situ Probes, using a Wagner Rapid RH probes only. It is recommended that moisture testing be
performed by a certified International Concrete Repair Institute (ICRI) Tier 2 Testing Technician – Grade 1. When tested at the
correct ambient temperature and humidity the maximum allowable should be 85% RH for the correct nora® wet adhesive and
nora® dryfix adhesive or 75% RH for nora® stepfix.
G.
If it is not possible to drill into the concrete for any reason as detailed in ASTM F2170 Standard Test Method for Determining
Relative Humidity in Concrete Floor Slabs Using in situ Probes, please contact the nora® Technical Department for other
recommendations.
H.
Only if it is not possible to provide a concrete substrate with acceptable moisture levels, or that (when appropriate) have a
confirmed effective vapor retarder, then a surface applied moisture mitigation system should be used that meets the
requirements of ASTM F3010 Standard Practice for Two-Component Resin Based Membrane-Forming Moisture Mitigation
Systems for Use Under Resilient Floor Coverings. Please note that all additional costs associated with this concrete condition
are the responsibility of the general contractor / end user, including any additional requirements for concrete preparation,
priming, leveler, patching or labor.
I.
A secure storage area that is maintained permanently or temporarily at ambient service temperature and humidity (except walk
in freezers or similar), or 68°F ± 5° F and 50% ± 10% relative humidity, for at least 48 hours prior to and during the application
of the flooring, so the flooring contractor can acclimate the flooring materials is required.
J.
An installation area that is weather tight and maintained either permanently or temporarily at ambient service temperature and
humidity (except walk in freezers or similar), or 68°F ± 5° F and 50% ± 10% relative humidity, for at least 48 hours prior to,
during and 72 hours after the application of the flooring is required.
K.
Areas with direct prolonged exposure to sunlight should be protected with the use of Low E glass doors and windows or
facades.
RESILIENT FLOORING
09650-6
L.
Areas of the flooring that are subject to direct sunlight through doors or windows should have them covered using blinds,
curtains, cardboard or similar for the time of the installation and 72 hours after the installation to allow the adhesive to cure.
Note: These areas should be installed using wet adhesives only.
M.
Prevent all traffic for a minimum of 12 hours and rolling loads for 72 hours to allow the adhesive to cure. If required, after 12
hours protect the flooring from damage during construction operations using Masonite, plywood or a similar product, ensuring
first that the flooring surface is free of all debris. Lay panels so that the edges form a butt joint and tape the joint to prevent
both movement and debris entrapment underneath them. Inspect immediately before covering and after removal for final
acceptance.
N.
Have the flooring cleaned no sooner than 72 hours (unless given written permission from the nora Technical Department) after
the installation using either the nora pro clean® system or a standard method as detailed in the appropriate nora ® Maintenance
Guide.
3.02
FLOORING CONTRACTOR RESPONSIBILITIES
A.
Provide trained installers that have at least one of the following:
1.
Approved by nora systems, Inc. for all of the requirements of the project or INSTALL (International Standards & Training
Alliance) certified for the requirements of the project.
2.
An effective installation manager, to manage the project, installers, and ensure that all of the required procedures are
followed as detailed in the nora Installation Guide (available at www.nora.com/us).
B.
Acclimate the flooring in the secure storage area provided by the general contractor that is maintained permanently or
temporarily at ambient service temperature and humidity (except walk in freezers or similar), or 68°F ± 5° F and 50% relative
humidity, for at least 48 hours prior to application.
C.
For wooden subfloors American Plywood Association (APA) underlayment grade plywood should be double sheeted at a
suitable thickness (minimum total wood thickness of 1 1/4 inch) to overlay the wooden substrate and installed as detailed in
ASTM F1482 Standard Practice for Installation and Preparation of Panel Type Underlayments to Receive Resilient Flooring.
Please note, as plywood will expand and contract due to changes in moisture content and temperature, nora systems, Inc.
cannot accept any liability of the plywood joints telegraphing through the finished floor.
D.
Perform mat bond tests in each major area (1 per ~1,000 sq. ft.) This should consist of the proposed subfloor preparation,
mitigation and leveling or smoothing products. A detailed method statement is available in the nora Installation Guide
(available at www.nora.com/us). Do not proceed with installation until all the results of the bond test are acceptable.
E.
Review and comply with all relevant Safety Data Sheets (SDS), local, state and federal regulations.
F.
Clean out and fill or repair any dormant saw cuts and cracks with an appropriate product following the manufacturers written
usage instructions. For any expansion (moving) joints, use an industry standard expansion joint assembly.
G.
When required, use a surface applied moisture mitigation system that meets the requirements of ASTM F3010, and following
the directions and requirements detailed in the manufacturers written instructions. Provide written confirmation and
photographs to the general contractor or end user that the subfloor was prepared correctly prior to the application of the
membrane, and that the membrane was applied correctly (without pin-holes) including confirmation of the gallons used and
total square feet installed.
H.
When required, use a leveler following the manufacturers written instructions. The surface should be free of dust, solvents,
paint, wax, varnish, oil, grease, asphalt, old adhesives, and other extraneous materials that may interfere with the bond. These
should be completely removed by mechanical means only. Dustless diamond grinding or bead blasting are the preferred
method to remove contaminates and bond breakers, as it also helps to level the concrete.
I.
Prime the subfloor prior to using a suitable leveler. Note: a 1/8 inch minimum thickness is required for the leveler to be
considered porous as required when using nora® 485 or 685 acrylic adhesives.
J.
Vacuum floors immediately prior to installing the flooring to remove all loose particles. If required, only use water based
sweeping compounds. Do not use any wax or oil based compounds that leave behind a residue that may interfere with the
adhesive bond.
