Installation of Sheets9.1 Deliver the sheets to the substrate in good condition.Handle the materials with care so as not to damage the sheets.9.1.1 Use care and diligence during insta

21、llation to avoiddamaging the substrate and sheet.9.1.2 Start the sheet installation at the low point of the deckor wall and work to the termination point.9.1.3 Field seams shall be perpendicular or parallel with thedirection of water flow. Avoid field seams that oppose thedirection of water flow.9.1

22、.4 Follow appropriate details in Guide D5898.9.2 Unroll or unfold the sheet and visually inspect forphysical damage prior to setting into location and performingthe attachment to the substrate and the field seaming betweensheets. Allow sheets to relax for a minimum of12 h. (Specifiershould consult m

23、anufacturer for recommendation.) (Use orremoval of questionable sheets shall be as agreed upon byproducer or system supplier, installer, and owners representa-tive.) Do not permanently install protection board until allareas of question and other defects are resolved.9.3 Align the sheet in its prope

24、r location maintaining arecommended splice overlap to the adjacent sheet. (Specifiershould consult manufacturer for splice width recommenda-tion.) Fold back the area to be adhered, making a rounded edge.Use temporary ballast of sand bags or bias ply tires asnecessary to hold the horizontal membrane

25、in position. Re-move foreign matter like sand, dirt, twigs, and so forth, whichmay have lodged under the sheet. Where dirt has contaminatedthe surface, clean the sheet in accordance with the manufac-turers recommendations.9.4 Horizontal Installation Procedure for Adhesively Bond-ing Sheet to Substra

26、te:9.4.1 Fold back one-half of the sheet, apply bonding adhe-sive continuously to the exposed substrate and the back of theexposed folded sheet at the producer or system suppliersrecommended rate. Do not apply bonding adhesive to theperimeter splice areas (recommended width of 15 cm 6 in.) ofthe she

27、et.9.4.2 Allow the bonding adhesive to dry (sufficient solventhas evaporated) to the point where it is still tacky, but will notstick to the finger when touched lightly.9.4.3 Carefully roll the sheet into the applied adhesive whilemaintaining a rounded leading edge, in a manner that mini-mizes voids

28、 and wrinkles. Keep the sheet even and continuerolling until the sheet is adhered.9.4.4 Apply positive pressure to adhered areas to obtaincontact between membrane and substrate. Use a stiff broom orlarge roller with rounded edges to embed the membrane intothe applied adhesive.9.4.5 Fold back the unb

29、onded portion of the sheet to exposethe unattached portion of the sheet.9.4.6 Repeat steps 9.4.1 through 9.4.4, be sure that noadhesive is applied on the perimeter splice areas of the sheet.9.5 Vertical Installation Procedure for Adhesively BondingSheet to Approved Substrate:9.5.1 Fanfold the membra

If horizontally, work from thebottom up for shingled splices.9.5.2 Fold back one-half of the sheet, apply bonding

31、 adhe-sive continuously to the substrate and the back of the foldedsheet and repeat procedure or completely to the back of thesheet at the recommended rate. Do not apply bonding adhesivein the splice area.9.5.3 Allow the bonding adhesive to dry (sufficient solventhas evaporated) to the point where i

32、t is still tacky, but will notstick to the finger when touched lightly.9.5.4 Carefully roll the sheet into the applied adhesive whilemaintaining a rounded leading edge or hang the membraneagainst the coated substrate in a manner that minimizes voidsand wrinkles. Keep the sheet even and continue roll

33、ing untilthe sheet is adhered.9.5.5 Apply positive pressure to adhered areas to attempt toobtain total contact between the membrane and substrate. Usea stiff brush or large roller with rounded edges to embed themembrane into the applied adhesive.9.6 Make field seams with producer or system supplieds

34、plicing systems. Prior to applying splicing adhesives to theD5843/D5843M 95 (2014)12waterproofing sheets at the job site, clean the splice areathoroughly with splice cleaner dispensed from underwriterslaboratory (UL) pump cans using clean natural fiber cloth.9.6.1 Apply the splice cleaner, primer, a

35、nd splicing adhesiveand allow for open time as recommended by producer orsystem supplier.9.6.2 Apply the in-the-seam sealant a minimum of 1.2 cm12 in. from the unexposed edge (if required by producer orsystem supplier for additional protection at splice intersec-tions).9.6.3 Join the mating surfaces

36、 carefully for a uniformcontact.9.6.4 Use a steel hand roller with rounded edges to applypositive pressure to the splice. Run the hand roller across theseam, from the inside of the top sheet to the edge of the fieldsplice to work out air bubbles.9.6.5 Inspect the outside edge for fishmouths. Where f

37、ish-mouths exist, cut the sheet to allow it to lay flat. Apply a patchof sheet material to the cut that extends a minimum of 15 cm6 in. in all directions beyond the defect in accordance withsplicing procedures noted in 9.6.1 through 9.6.4.9.6.6 After cleaning the seam edge with splice cleaner,apply

38、and feather lap-seam sealant by the end of each dayswork. Inspect lap-seam sealant for continuous contact withboth sheets.9.6.7 Complete all field seams and secure and make water-tight all terminations by the end of each work day.9.7 Flashings, Terminations, Tie-Ins, and Expansion Joints:9.7.1 Flash

39、ings and termination should extend a minimumof 20 cm 8 in. above the grade.9.7.2 Flash penetrations inside and outside corners usingseparate uncured flashing materials.9.7.3 Secure the membrane edge to the substrate by using atermination bar or reglet when stopping the membrane and usecounterflashin

40、g when extending the membrane above thegrade.9.7.4 Consult the producer or system supplier for recom-mended tie-ins.9.8 Take precautions necessary to provide protection of thewaterproofing system before the end of the day.9.8.1 The loose edge of the sheet shall have a watertight sealto the substrate

41、 to prevent water from penetrating any com-pleted section of the waterproofing system.9.8.2 Do not abuse completed sections by subsequent ma-terial handling operations and traffic.9.8.3 Temporary protection of the membrane shall be pro-vided at the end of each days work with a minimum 3 mm 18in. pro
