Check underlayment panel manufacturers specificrecommendations.8.7 The temperature conditions for installing resilient floor-ing products and related sundries is typically 65 to 80F (18 to27C) for 48 h before, during and after the installation, thenmust remain within the range of 55 to 100
28、F (13 to 38C)thereafter.9. Installation of Panel Underlayment9.1 General Considerations:9.1.1 Underlayments to receive resilient flooring directly orpanel underlayment shall be permanently dry, clean, smooth,structurally sound and in compliance with local building codes.They shall be free of dust, s
29、olvent, paint, wax, oil, grease,residual adhesive, adhesive removers, and other foreign mate-rials that might prevent adhesive bond or cause staining ofresilient flooring.9.1.2 A common floor joist spacing is a maximum of 16 in.(405 mm) on center. Joist spacing shall comply with localbuilding codes.
30、9.1.3 Wood subfloors to receive panel underlayment shall besuspended at least 18 in. (460 mm) above the ground, withadequate cross ventilation. Use of a vapor barrier on the groundsurface, using overlapping widths and lengths to reduce highhumidity from ground moisture into the crawlspace below thew
31、ood subfloor is recommended where appropriate.9.2 Preparation of New Wood Floors:9.2.1 A combination of the wood subfloor and panel under-layment shall be of double layer construction. Refer to theresilient flooring manufacturers recommendations and localbuilding codes for references to minimum thic
32、kness.9.2.2 Install panel underlayment just before the installationof the finished resilient flooring and protect it from construc-tion traffic, staining, denting or other potential damage.9.2.3 Install with long dimension of the underlaymentpanels perpendicular to the floor joists for maximum rigid
33、ity.9.2.4 Install with underlayment panel edges offset from anysubfloor joints or edges by at least 6 in. (150 mm).9.2.5 Offset panel underlayment joints by at least 16 in. (405mm), and make sure panel underlayment is staggered such thatfour-panel corners do not meet.9.2.6 Use only non-staining fast
34、eners to secure panel under-layment.9.2.6.1 For14 to12 in. (6.4 to 12.7 mm) thick underlaymentpanels, use 3d ring-shank nails spaced 3 in. (75 mm) on centeralong panel edges,38 in. from ends and edges (9.5 mm) and 6in. (150 mm) on center over panel field. Staples are also widelyutilized as fasteners
35、; refer to panel underlayment manufactur-ers recommendations as to type, length and crown orientationof staples for the thickness underlayment being fastened. Also,check resilient manufacturers recommendations. Oil fromfastening equipment can stain resilient flooring. It is the panelinstallers respo
36、nsibility to make sure equipment is wellmaintained (does not leak excess oil) and that non-staininglubricating oils are utilized.9.2.6.2 For underlayment panels from1932 to34 in. (15.1 to19 mm) thick, use 4d ring-shank nails spaced 6 in. (150 mm)on center at panel edges and 8 in. (200 mm) on center
37、overpanel field.9.3 Preparation of Existing Wood Subfloors or Panel Un-derlayment:9.3.1 The resilient flooring manufacturer shall be consultedregarding the removal of old resilient flooring, adhesiveresidue, or other surface contaminants. If old resilient flooringor adhesive residue is to be removed
38、, follow the RFCIs“Recommended Work Practices for Removal of Resilient FloorCovering.”9.3.2 Stripwood plank or any board type subfloors are notacceptable under-floors for the direct installation of resilientflooring. If stripwood is 3 in. (75 mm) or less in width and istongue-and-groove and with a s
39、mooth surface, use minimum14 in. (6.4 mm) approved panel underlayment to cover andreduce the potential of board telegraphing. For boards widerthan 3 in. (75 mm) or not tongue-and-groove, or with a roughsurface, use minimum12 in. (12.7 mm) thick approved panelunderlayment.9.4 Protection of Panel Unde
40、rlayment After Installation:9.4.1 Because satisfactory performance of resilient flooringdepends in a large part on the condition of the underlayment,care shall be taken to avoid traffic on the finished underlaymentinstallation or the surface protected by temporary walkingboards or other protective c
41、overing that will not cause potentialbond or staining issues, for example, asphalt saturated paper.Ideally, the fully acclimatized underlayment should be installedjust prior to installation of the resilient flooring.9.4.2 Damage to the underlayment can occur if water, oil,paint, spackling compounds,
42、 solvent, dirt, and other debris areF 1482 04 (2009)13spilled or tracked onto the underlayment. In addition, paint andsolvent spills on underlayment may migrate to the surface ofresilient flooring and cause a stain.Any damage to the installedunderlayment must be repaired or replaced prior to install
43、ationof the resilient flooring.10. Preparation of Panel Underlayment to ReceiveResilient Flooring10.1 Proper spacing and placement of underlayment paneljoints, relative to each other, to the subfloor joints, as well as tothe supporting joists is important. Follow local building coderequirements and
44、panel underlayment manufacturers pub-lished recommendations.10.2 Protruding nails and other protrusions should be drivenflush, sanded smooth or driven below the surface, then patchedand sanded smooth.10.3 The surface of the floor shall be cleaned of all loosematerial by scraping, brushing, vacuuming
45、, other methods, orcombination thereof, recommended by resilient flooring manu-facturer, immediately before commencing installation of resil-ient flooring.10.4 Surface cracks, grooves, depressions, and other irregu-larities shall be filled or smoothed with appropriate patching orunderlayment compoun
46、d for filling or smoothing, or both,wood, fiber-cement, or gypsum fiber panel surfaces. Patchingand self-leveling compounds for use on panel underlaymentsshall be moisture- and alkali-resistant and suitable for com-mercial installations. Refer to resilient flooring manufacturerswritten installation
47、instructions and to the patching and self-leveling compound manufacturers published recommenda-tions for mix and application instructionsNOTE 1Some panel underlayment manufacturers limit the types ofpatching and self-leveling compounds suitable for use with their products.Consult the panel underlaym
