18、enitions For denitions of terms used in this practice, see Terminology F141. 3.2 Denitions of Terms Specic to This Standard: 3.2.1 mat, as in “mat test”a sample of vapor-retardant sheet resilient oor nish material or equivalent. 3.2.2 moisture vapor emissiona term used by the ooring industry in the
19、U.S. to measure moisture emission from concrete oors in lb/1000 ft 2 24 h (56.51 g/(s m 2 ) using the anhydrous calcium chloride test. 4. General Guidelines 4.1 The installation of a permanent, effective moisture vapor retarder with a minimum thickness of 0.010 in. and a permeance of 0.1 y, as descr
20、ibed in Specication E1745 is required under all on- or below-grade concrete oors. The use of such a moisture vapor retarder, provided its integrity has not been compromised, reduces potential severity of water vapor penetration. Every concrete oor slab on- or below-grade to receive resilient ooring
21、shall have a water vapor retarder (often improperly called a vapor barrier) installed directly below the slab. 4.2Concrete oors to receive resilient ooring shall be permanently dry, clean, smooth, and structurally sound. They shall be free of dust, solvent, paint, wax, oil, grease, residual adhesive
22、, adhesive removers, lm-forming curing compounds, silicate penetrating curing compounds, sealing, hardening, or parting compounds, alkaline salts, excessive carbonation or laitence, mold, mildew, and other foreign materials that might prevent adhesive bond. 4.2 The surface of concrete oors to receiv
23、e resilient ooring shall be dry, clean, smooth, and structurally sound. They shall be free of dust, solvent, paint, wax, oil, grease, residual adhesive, adhesive removers, lm-forming curing compounds, silicate penetrating curing compounds, sealing, hardening, or parting compounds, alkaline salts, ex
24、cessive carbonation or laitence, mold, mildew, and other foreign materials that might affect the rate of moisture dissipation from the concrete, the adhesion of resilient ooring to the concrete or cause a discoloration of the ooring from below. Non-chemical methods for removal, such as abrasive clea
25、ning or bead-blasting, including methods described in Practice D4259 may be used on existing slabs with deleterious residues. 4.2.1 WarningHydrauliccementusedinconcreteconstructionmaycontaintraceamountsoffreecrystallinesilica.Prolonged exposure to airborne free crystalline silica may be a health haz
26、ard. Avoid actions that cause dust to become airborne. Use local or general ventilation to control exposures below applicable exposure limits. 4.2.2 WarningSee 7.1.1 and 7.1.2 for warnings regarding asbestos and lead paint. 4.3 Surface cracks, grooves, depressions, control joints or other non-moving
27、 joints, and other irregularities shall be lled or smoothed with latex patching or underlayment compound recommended by the resilient ooring manufacturer for lling or smoothing, or both. Patching or underlayment compound shall be moisture-, mildew-, and alkali-resistant, and, for commercial installa
28、tions,shallprovideaminimumof3000psicompressivestrengthafter28days,whentestedinaccordancewithTestMethod C109/C109M or Test Method C472, whichever is appropriate. 4.3.1 Joints such as expansion joints, isolation joints, or other moving joints in concrete slabs shall not be lled with patching compound
29、or covered with resilient ooring. Consult the resilient ooring manufacturer regarding the use of an expansion joint covering system. 4.4 The surface of the oor shall be cleaned of all loose material by scraping, brushing, vacuuming, or other methods, or a combination thereof, as recommended by the r
30、esilient ooring manufacturer, immediately before commencing installation of resilient ooring. 4.5 Many resilient oorings may not be installed over concrete when residual asphalt adhesive residue is present. Consult the resilient ooring manufacturers written recommendations concerning use of resilien
31、t ooring products in these situations. 4.6 Concrete oors shall be smooth to prevent irregularities, roughness, or other defects from telegraphing through the new resilient ooring. The surface of concrete oors shall be at to within the equivalent of 3 16 in. (3.9 mm) in 10 ft, (as described in ACI 11
32、7R, or as measured by the method described in Test Method E1155 or any industry-recognized method specied) and within the equivalent of 1/32 in. (0.8 mm) in 12 in. (305 mm). See X1.7 for more information regarding atness measurement methods. 4.7 AcclimationBecause of the role acclimation plays in a
33、successful installation, most resilient ooring manufacturers recommend or require that their ooring products, sundry supplies (adhesives, coatings, welding rods, etc.) and the area to receive the resilient ooring are properly conditioned. Consult oor covering and sundry manufacturers for appropriate
34、 temperature and humidity range for the products to be installed and the geographic area where the job site is located. General recommendations are for the installation area and materials listed above to be maintained at a minimum of 65F (18.3C) and a maximum of 85F (29.4C) for 48 h before, during a
35、nd for 48 h after completion of the installation. Relative humidity level extremes should also be avoided because of their inuence on proper drying and curing of patching compounds and adhesives.

If a system other than the permanent HVAC source is utilized, it must provide proper control of both temperature and humidity to recommended or specic levels for the appropriate time duration. 5. Testing P
37、rocedures 5.1Concrete oors to receive resilient ooring shall be free of dust, solvent, paint, wax, oil, grease, residual adhesive, adhesive removers, sealers, coatings, nishes, dirt, lm-forming curing compounds, silicate penetrating curing compounds, hardening or parting compounds, alkaline salts, e
38、xcessive carbonation or laitance, mold, mildew, and other foreign materials which may affect the rate of moisture dissipation from the concrete or the adhesion of resilient ooring to the concrete. Non-chemical methods for removal, such as abrasive cleaning or bead-blasting, including methods describ
39、ed in Practice D4259 may be used on existing slabs with deleterious residues to achieve an appropriate state for testing. Cleaning shall take place a minimum of 24 h before testing. WarningHydraulic cement used in concrete construction may contain trace amounts of free crystalline silica. Prolonged
40、exposure to airborne free crystalline silica may be a health hazard. Avoid actions that cause dust to become airborne. Use local or general ventilation to control exposures below applicable exposure limits. 5.2 5.1 Moisture TestingAll concrete slabs shall be tested for moisture regardless of age or
41、grade level. For the preferred moisture testing method and limits, consult the written instructions from the oor covering manufacturer, the adhesive manufacturer, the patching/underlayment manufacturer, or combination thereof. In the absence of manufacturers guidelines, refer to Table 1. 5.21.1 Cons
42、ult the resilient ooring manufacturer, the adhesive manufacturer, the underlayment manufacturers written instructions, or combination thereof, for their acceptable test methods. If these instructions are in conict, the most stringent requirements shall apply. 5.35.2 pH TestingConcrete oors shall be
43、tested for pH prior to the installation of resilient ooring. Levels of pH shall not exceed the written recommendations of the resilient ooring manufacturer or the adhesive manufacturer, or both. 5.3.1To5.2.1 To test for pH at the surface of a concrete slab, use wide range pH paper, its associated pH
44、 chart, and distilled or deionized water. Place several drops of water on a clean surface of concrete, forming a puddle approximately 1 in. (25 mm) in diameter. Allow the puddle to set for 606 5 s, then dip the pH paper into the water. Remove immediately, and compare to chart to determine pH reading
45、. Other pH testing methods such as pH pencils or pH meters, or both, are available and may be used to measure pH. Readings below 7.0 and in excess of 10.0 have been known to affect resilient ooring or adhesives, or both. Refer to resilient ooring manufacturers written instructions for guidelines on
46、acceptable testing methods and acceptable pH levels. See X1.4 for more information about pH levels in concrete slabs. 6. Preparation of New Concrete Floors 6.1 New concrete slabs shall be properly cured and dried or treated before installation of resilient ooring. Drying time before slabsarereadyfor
47、moisturetestingwillvarydependingonatmosphericconditionsandmixdesign.SeeX1.3formoreinformation. Floors containing lightweight aggregate or excess water, and those which are allowed to dry from only one side, such as concrete over a moisture vapor retarder or concrete on metal deck construction, may n
48、eed a much longer drying time and should not be covered with resilient ooring unless the moisture vapor emission rate or the percentage of internal relative humidity meets the manufacturers installation specications. 7. Preparation of Existing Concrete Floors 7.1 The resilient ooring manufacturer sh
49、all be consulted regarding the necessity of removal of old resilient ooring, adhesive residue, paint, or other surface contaminants. If old resilient ooring, paint, or adhesive residue is to be removed, follow 7.1.1 and 7.1.2: 7.1.1 WarningDo not sand, dry sweep, dry scrape, drill, saw, beadblast, or mechanically chip or pulverize existing resilient ooring, backing, lining felt, paint, asphaltic cutback adhesives, or other adhesives.
