Mix only that quantity which can be used within its potlife. ■ 7 Sikedur-Combflexe SC system 711 PDF created with pdfFactory Pro trial version www.pdffactory.com EFTA01121245  Application Method I Selection of tape size: Tools Selection of the correct tape size (thickness and width) and of a suitable Sika° adhesive depends on the expected performance. If necessary. ask for technical advice. Tapes of 1 mm thickness are suitable for sealing of joints subject to light load only. Max. permissible permanent elongation: 1 mm tape: 10% of the non adhered tape width 2 mm tape: 25% of the non adhered tape width Note: For higher movement, place and fix tape in a loop into the joint. Application of tape: In case of dirt clean the surface of the Sikadur-Combiflee SG Tape with a dry or wet cloth. Use water and no solvent for cleaning. Check the Sikadur-Combillee SG Tape in respect of damages during storage and transport (e.g. heavy scratches) and remove critical parts if necessary. Note: No activation on site required In case of expansion joints or cracks > 1 mm the centre of the tape must not be "bonded" to the substrate. In this case, apply masking tape on top of the joint / crack and on both sides of the joint before applying the adhesive. Apply a suitable thoroughly mixed Sikadurt° adhesive on both sides of the joint / crack onto the prepared substrate, using a suitable trowel. If the concrete substrate is damp. force the adhesive well into the substrate. Layer thickness of adhesive should be 1 - 2 mm and the width on each side at least 40 mm. Before placing the Combiflex tape remove the masking tape on top of the expansion joint / crack. Apply the Combiflex tape within the open time of the adhesive. Press the tape firmly and without trapping air into the adhesive by using a suitable roller. The adhesive should be squeezed out on both sides of the tape by - 5 mm. In cases of expansion joints / cracks > 1 mm apply the Sikadur-Combiflexe SG-10/-20 M Tape with the red red masking tape facing upwards. In cases of high joint movement place the tape as a loop into the joint. For fixing overhead or in difficult configurations, the tape may be temporarily held in place with Skit Trocal Adhesive C-705. This adhesive, however may only be used in the tape centre but never on the areas to be bonded with Sikadur-Combiflex® CF Adhesive, SikadurQs-31 CF or Sikadurt9-31 DW. 8 Sikedur-Combflexe SC system VII PDF created with pdfFactory Pro trial version www.pdffactory.com EFTA01121246  Let the base layer of the SikadurQ1-Combiflext CF Adhesive. and Sikadurg-31 CF resp. Sikadurt9-31 DW lightly harden before the top layer is applied. Apply the adhesive at a thickness of - 1 mm on both sides of the joint / crack. producing a cover which tapers outwards to almost zero. This is followed by the removal of the red middle strip and the masking tape on both sides to ensure a neat and precise detail. The adhesive top layer may be smoothed with a brush using a diluted detergent. Allow adhesive to start curing first. Note: Do not use detergent if any coating is to be applied. When sealing construction joints or cracks of up to 1 mm width, the tape may be completely covered with Sikadurg-Combiflexe CF Adhesive. Sikadurw-31 CF or Sikadure-31 DW which also then provides mechanical protection. In these instances the Sikadur-Combiflext SG Tape must be applied with the red middle strip facing downwards. Connection of Sikadur-Combiflex® SG Tape: Tape ends are connected by hot air thermal welding The welding area must be prepared by roughing the surface by scotch brite or sand paper. Roughen the tapes only in the welding area otherwise the bonding effect can be affected. Overlaps have to be 40 - 50 mm. Connection of Stkadur-Combiflex® SG Tape with Sucas PVC External Waterbar Type AR (only for construction joints): Sikadur-Combiflex® SG Tape must overlap the Waterbar Type AR by at least a tape width. Clean the Sikadur-Combiflexg SG Tape with a dry cloth. Clean the waterbar with Sika® Colma-Cleaner and let it dry. Prime waterbar with Sika® Aktivator and allow to dry (min. 30 minutes, max. 24 hours). Bond the Combiflex tape and the Sika Waterbar together using Sikaffet-11 FC adhesive sealant at the thickness of 1 - 3 mm. Overcoat the contact areas by spatula with Sikaflexe-11 FC. Cleaning of Tools Clean all tools and application equipment with Sikaw Colma-Cleaner immediately after use. Hardened / cured material (adhesive) can only be mechanically removed. 9 Sikedur-Combflexe SC system 9/I PDF created with pdfFactory Pro trial version www.pdffactory.com EFTA01121247  Potlite Sikadur-Combitlexe CF Adhesive (6 kg) Temperature Type Normal Type Rapid +5°C - - 60 minutes +10°C - 125 minutes - 45 minutes +15°C - 95 minutes - 25 minutes +23°C - 50 minutes • +30°C - 25 minutes • Sikadure-31 CF (0.2 kg) Type Slow Type Normal Type Rapid +5°C - - - 60 minutes +10°C - - 145 minutes - 55 minutes +23°C - 135 minutes - 55 minutes - 40 minutes +30°C - - 35 minutes - +35°C - 70 minutes - +45°C - 45 minutes - - Temperature Sikadur•31 DW (0.2 kg) +23°C - 90 minutes If larger quantities are being mixed the temperature of the adhesive will increase due to the chemical reaction, resulting in a reduced potlife. Waiting Time / The Sikadure-Combiflexe CF Adhesive, Sikadue-31 CF and Sikadure-31 DW may Overcoating be overcoated with an epoxy coating. In this case do not smooth the adhesive with detergent. If the waiting time between application of adhesive and overcoating is to be longer than 2 days, the adhesive must be blinded to excess with quartz sand immediately after application. Notes on Application If joints are to be subjected to water pressure, the tape must be supported in the Limitations joint. Hard foam or joint sealant is recommended. For exposure to negative water pressure the Sikadur-Combiflexe SG Tape must be secured with a steel plate fixed on one side. Limit without support: For 5 mm joints at +20°C and max. 1 bar water head a tape of 2 mm thickness has to be installed. If a bituminous wearing layer is installed on top of Sikadur-Combiflexe SG System the temperature of the hot mix must not exceed +180°C up to max. 50mm thickness. Up to 10 mm thickness the temperature may be max. +220°C. If necessary apply in layers and allow to cool in between. The Sikadur-Combiflexe SG Tape must be protected from mechanical damage. The Sikadur-Combiflexe SG Tape can not be connected to the Sikaplan WT membranes by hot air welding. All technical data stated in this Product Data Sheet are based on laboratory tests.
