General Guidelines4.1 The installation o

18、f a permanent, effective moisture vaporretarder with a minimum thickness of 0.010 in. and a per-meance of 0.1 y, as described in Specification E 1745 isrequired under all on- or below-grade concrete floors. The useof such a moisture vapor retarder, provided its integrity has notbeen compromised, red

19、uces potential severity of water vaporpenetration. Every concrete floor slab on- or below-grade toreceive resilient flooring shall have a water vapor retarder(often improperly called a vapor barrier) installed directlybelow the slab.4.2 Concrete floors to receive resilient flooring shall bepermanent

20、ly dry, clean, smooth, and structurally sound. Theyshall be free of dust, solvent, paint, wax, oil, grease, residualadhesive, adhesive removers, film-forming curing compounds,silicate penetrating curing compounds, sealing, hardening, orparting compounds, alkaline salts, excessive carbonation orlaite

21、nce, mold, mildew, and other foreign materials that mightprevent adhesive bond.4.3 Surface cracks, grooves, depressions, control joints orother non-moving joints, and other irregularities shall be filledor smoothed with latex patching or underlayment compoundrecommended by the resilient flooring man

22、ufacturer for fillingor smoothing, or both. Patching or underlayment compoundshall be moisture-, mildew-, and alkali-resistant, and, forcommercial installations, shall provide a minimum of 3000 psicompressive strength after 28 days, when tested in accordancewith Test Method C 109 or Test Method C 47

23、2, whichever isappropriate.4.3.1 Joints such as expansion joints, isolation joints, orother moving joints in concrete slabs shall not be filled withpatching compound or covered with resilient flooring. Consultthe resilient flooring manufacturer regarding the use of anexpansion joint covering system.

24、4.4 The surface of the floor shall be cleaned of all loosematerial by scraping, brushing, vacuuming, or other methods,or a combination thereof, as recommended by the resilientflooring manufacturer, immediately before commencing instal-lation of resilient flooring.4.5 Many resilient floorings may not

25、 be installed overconcrete when residual asphalt adhesive residue is present.Consult the resilient flooring manufacturers written recom-mendations concerning use of resilient flooring products inthese situations.4.6 Concrete floors shall be smooth to prevent irregularities,roughness, or other defect

(3.9 mm) in 10 ft, (as describedin ACI 117R, or as measured by the method described in TestMethod E 1155 or any industry-recognized method specified)and within the eq

27、uivalent of 1/32 in. (0.8 mm) in 12 in. (305mm). See X1.7 for more information regarding flatness mea-surement methods.5. Testing Procedures5.1 Concrete floors to receive resilient flooring shall be freeof dust, solvent, paint, wax, oil, grease, residual adhesive,adhesive removers, sealers, coatings

Non-chemical methods for removal, such as abrasivecleaning or bead-blasting, including methods described inPractice D 4259 may be used on existing slabs with deleteriousresidues to achieve an appropriate state for testing. Cleaningshall take place a minimum of 24 h

30、before testing. WarningHydraulic cement used in concrete construction may containtrace amounts of free crystalline silica. Prolonged exposure toairborne free crystalline silica may be a health hazard. Avoidactions that cause dust to become airborne. Use local or generalventilation to control exposur

31、es below applicable exposurelimits.5.2 Moisture TestingAll concrete slabs shall be tested formoisture regardless of age or grade level. For the preferredmoisture testing method and limits, consult the written instruc-tions from the floor covering manufacturer, the adhesivemanufacturer, the patching/

32、underlayment manufacturer, orcombination thereof. In the absence of manufacturers guide-lines, refer to Table 1.5.2.1 Consult the resilient flooring manufacturer, the adhe-sive manufacturer, the underlayment manufacturers writteninstructions, or combination thereof, for their acceptable testmethods.

33、 If these instructions are in conflict, the most stringentrequirements shall apply.5.3 pH TestingConcrete floors shall be tested for pH priorto the installation of resilient flooring.

Place several drops of water on a cleansurface of concr

Remove immediately, and com-pare to chart to determine pH reading. Other pH testingmethods such as pH pencils or pH meters, or both, are availableand may be used t

37、o measure pH. Readings below 7.0 and inexcess of 10.0 have been known to affect resilient flooring oradhesives, or both. Refer to resilient flooring manufacturerswritten instructions for guidelines on acceptable testing meth-ods and acceptable pH levels. See X1.4 for more informationabout pH levels

38、in concrete slabs.6. Preparation of New Concrete Floors6.1 New concrete slabs shall be properly cured and dried ortreated before installation of resilient flooring. Drying timebefore slabs are ready for moisture testing will vary dependingon atmospheric conditions and mix design. See X1.3 for morein

39、formation. Floors containing lightweight aggregate or excesswater, and those which are allowed to dry from only one side,such as concrete over a moisture vapor retarder or concrete onmetal deck construction, may need a much longer drying timeand should not be covered with resilient flooring unless t

40、hemoisture vapor emission rate or the percentage of internalrelative humidity meets the manufacturers installation speci-fications.7. Preparation of Existing Concrete Floors7.1 The resilient flooring manufacturer shall be consultedregarding the necessity of removal of old resilient flooring,adhesive

41、 residue, paint, or other surface contaminants. If oldresilient flooring, 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 existingresilient flooring, backing, lining felt, pain

Inha-lation of such dust is a cancer and respiratory tract hazard.Smoking by individuals exposed to asbestos fibers greatlyincreases the risk of serious bodily har

Regulations may require thatthe material be tested to determine asbestos content. TheResilient Floor Covering Institutes (RFCIs) recommendedwork practices for removal of existing resi

Exposureto excessive amounts of lead dust presents a health hazard.Refer to applicable federal, state, and

45、 local laws and guidelinesfor hazard identification and abatement of lead-based paintpublished by the U.S. Department of Housing and UrbanDevelopment7regarding appropriate methods for identifyinglead-based paint and removing such paint, and any licensing,certification, and training requirements for
