Check underlayment pane

27、l 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 100F (13 to 38C)thereafter.9. Instal

28、lation 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, solvent, paint, wax, oil, grease,r

29、esidual 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 16 in. (405 mm) oncenter. Other joist spacing such as nominal 20 in. on center(19.2 in. actual) or 24 in. on center are perm

30、itted dependentupon joist and panel systems. Joist spacing shall comply withlocal building codes.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 overlapp

31、ing widths and lengths to reduce highhumidity from ground moisture into the crawlspace below thewood 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 theresili

32、ent flooring manufacturers recommendations and localbuilding codes for references to minimum thickness.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

33、with long dimension of the underlaymentpanels perpendicular to the floor joists for maximum rigidity.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 u

34、nderlayment is staggered such thatfour-panel corners do not meet.9.2.6 Use only non-staining fasteners 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

35、.5 mm) and 6in. (150 mm) on center over panel field. Staples are also widelyutilized as fasteners; 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 recommend

36、ations. Oil fromfastening equipment can stain resilient flooring. It is the panelinstallers responsibility 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, us

37、e 4d ring-shank nails spaced 6 in. (150 mm)on center at panel edges and 8 in. (200 mm) on center 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, adhesiveresi

38、due, or other surface contaminants. If old resilient flooringor adhesive residue is to be removed, 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 resil

39、ientflooring. If stripwood is 3 in. (75 mm) or less in width and istongue-and-groove and with a smooth surface, use minimum14 in. (6.4 mm) approved panel underlayment to cover andreduce the potential of board telegraphing. For boards widerF1482 153than 3 in. (75 mm) or not tongue-and-groove, or with

40、 a roughsurface, use minimum12 in. (12.7 mm) thick approved panelunderlayment.9.4 Protection of Panel Underlayment 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 f

41、inished underlaymentinstallation or the surface protected by temporary walkingboards or other protective covering 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 t

42、he resilient flooring.9.4.2 Damage to the underlayment can occur if water, oil,paint, spackling compounds, solvent, dirt, and other debris arespilled or tracked onto the underlayment. In addition, paint andsolvent spills on underlayment may migrate to the surface ofresilient flooring and cause a sta

43、in.Any damage to the installedunderlayment must be repaired or replaced prior to installationof 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 w

44、ell as tothe supporting joists is important. Follow local building coderequirements and 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 sur

45、face of the floor shall be cleaned of all loosematerial by scraping, brushing, vacuuming, other methods, orcombination thereof, recommended by resilient flooringmanufacturer, immediately before commencing installation ofresilient flooring.10.4 Surface cracks, grooves, depressions, and other irregu-l

46、arities shall be filled or smoothed with appropriate patching orunderlayment compound 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-m

47、ercial installations. Refer to resilient flooring manufacturerswritten installation 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

48、-leveling compounds suitable for use with their products.Consult the panel underlayment manufacturers published applicationinstructions for any finishing limitations.11.
