19、.2.2 moisture vapor emissiona term used by the flooring industry in the U.S. to measure moisture emission from concretefloors in lb/1000 ft2 24 h (56.51 g/(s m2) using the anhydrous calcium chloride test.4. General Guidelines4.1 The installation of a permanent, effective moisture vapor retarder with
20、 a minimum thickness of 0.010 in. and a permeanceof 0.1 y, as described in Specification E1745 is required under all on- or below-grade concrete floors. The use of such a moisturevapor retarder, provided its integrity has not been compromised, reduces potential severity of water vapor penetration. E
21、veryconcrete floor slab on- or below-grade to receive resilient flooring shall have a water vapor retarder (often improperly called avapor barrier) installed directly below the slab.4.2 The surface of concrete floors to receive resilient flooring shall be dry, clean, smooth, and structurally sound.
22、They shall befree of dust, solvent, paint, wax, oil, grease, residual adhesive, adhesive removers, film-forming curing compounds, silicatepenetrating curing compounds, sealing, hardening, or parting compounds, alkaline salts, excessive carbonation or laitence, mold,mildew, and other foreign material
23、s that might affect the rate of moisture dissipation from the concrete, the adhesion of resilientflooring to the concrete or cause a discoloration of the flooring from below.

Prolongedexposure to airborne free crystalline silica may be a health hazard. Avoid actions that cause dust to become airborne. Use

29、ately before commencing installation ofresilient flooring.4.5 Many resilient floorings may not be installed over concrete when residual asphalt adhesive residue is present. Consult theresilient flooring manufacturers written recommendations concerning use of resilient flooring products in these situ
30、ations.4.6 Concrete floors shall be smooth to prevent irregularities, roughness, or other defects from telegraphing through the newresilient flooring. The surface of concrete floors shall be flat to within the equivalent of 316 in. (3.9 mm) in 10 ft, (as describedin ACI 117R, or as measured by the m
31、ethod described in Test Method E1155 or any industry-recognized method specified) andwithin the equivalent of 1/32 in. (0.8 mm) in 12 in. (305 mm).

General recommendedhumidity control level is between 35 55 %. If a system other than the permanent HVAC source is utilized,
36、it must provide propercontrol of both temperature and humidity to recommended or specific levels for the appropriate time duration.5. Testing Procedures5.1 Moisture TestingAll concrete slabs shall be tested for moisture regardless of age or grade level. For the preferred moisturetesting method and l
37、imits, consult the written instructions from the floor covering manufacturer, the adhesive manufacturer, thepatching/underlayment manufacturer, or combination thereof. In the absence of manufacturers guidelines, refer to Table 1.5.1.1 Consult the resilient flooring manufacturer, the adhesive manufac
38、turer, the underlayment manufacturers writteninstructions, or combination thereof, for their acceptable test methods. If these instructions are in conflict, the most stringentrequirements shall apply.5.2 pH TestingConcrete floors shall be tested for pH prior to the installation of resilient flooring
39、. Levels of pH shall not exceedthe written recommendations of the resilient flooring manufacturer or the adhesive manufacturer, or both.5.2.1 To test for pH at the surface of a concrete slab, use wide range pH paper, its associated pH chart, and distilled or deionizedwater. Place several drops of wa
40、ter on a clean surface of concrete, forming a puddle approximately 1 in. (25 mm) in diameter.Allow the puddle to set for 6065 s, then dip the pH paper into the water. Remove immediately, and compare to chart to determinepH reading. Other pH testing methods such as pH pencils or pH meters, or both, a
41、re available and may be used to measure pH.Readings below 7.0 and in excess of 10.0 have been known to affect resilient flooring or adhesives, or both. Refer to resilientflooring manufacturers written instructions for guidelines on acceptable testing methods and acceptable pH levels. See X1.4 formor
42、e information about pH levels in concrete slabs.6. Preparation of New Concrete Floors6.1 New concrete slabs shall be properly cured and dried or treated before installation of resilient flooring. Drying time beforeslabs are ready for moisture testing will vary depending on atmospheric conditions and
43、 mix design. See X1.3 for more information.Floors containing lightweight aggregate or excess water, and those which are allowed to dry from only one side, such as concreteover a moisture vapor retarder or concrete on metal deck construction, may need a much longer drying time and should not becovere
44、d with resilient flooring unless the moisture vapor emission rate or the percentage of internal relative humidity meets themanufacturers installation specifications.7. Preparation of Existing Concrete Floors7.1 The resilient flooring manufacturer shall be consulted regarding the necessity of removal
45、 of old resilient flooring, adhesiveresidue, paint, or other surface contaminants. If old resilient flooring, paint, or adhesive residue is to be removed, follow 7.1.1 and7.1.2:7.1.1 WarningDo not sand, dry sweep, dry scrape, drill, saw, beadblast, or mechanically chip or pulverize existing resilien
46、tflooring, backing, lining felt, paint, asphaltic cutback adhesives, or other adhesives. These products may contain asbestos fibers orcrystalline silica. Avoid creating dust. Inhalation of such dust is a cancer and respiratory tract hazard. Smoking by individualsexposed to asbestos fibers greatly in
47、creases the risk of serious bodily harm. Unless positively certain that the product is anonasbestos-containing material, presume that it contains asbestos. Regulations may require that the material be tested to determineasbestos content. The Resilient Floor Covering Institutes (RFCIs) recommended wo
48、rk practices for removal of existing resilientfloor coverings should be consulted for a defined set of instructions addressed to the task of removing all resilient floor coveringstructures.7.1.2 WarningCertain paints may contain lead. Exposure to excessive amounts of lead dust presents a health haza

Referto applicable federal, state, and local laws and guidelines for hazard identification and abatement of lead-based paint published bythe U.S. Department of Housing and Urban Development6 regarding appropriate methods for identifying lead-based paint andremoving such paint, and any licensing, certification, and training requirements for persons performing lead abatement work.6 Lead-Based Paint: Interim Guidelines for Hazard Identification and Abatement in Public and Indian Housing, U.S. Department of Housing and Urban Development,Washington
