Larger surface irregularities or steps <br />must be levelled out beforehand by means of suitable <br />mortar systems or suitable fillers, e.g. sand. <br />In the case of applications underneath floor slabs on <br />compacted, pressure-resistant, capillary-breaking layers, <br />there must be no sharp-edged or pointed components on <br />the surface. <br />Formwork may not deform during the concreting works. In <br />the case of vertical applications, the top finishing rail must <br />be secured using suitable measures.</p> <p>Watertightness in accordance <br />with EN 1928, <br />procedure B 60 kPa/24h): Watertight <br />Water vapour resistance <br />factor (EN 1931): </p> <p>700 mm</p> <p>approx. 29 m</p> <p>Tensile strength (MD/CMD), <br />in accordance with <br />EN 12311-2: <br />1056/1056 N/ 50 mm</p> <p>1/3</p> <p>05/19</p> <p>Application: <br />The substrate must be firm and load-bearing. Overlaps <br />should be established with min. 5 cm, and bonded through <br />hot air-welding or adhered with AQUAFIN-CA.</p> <p>layer. In doing so, direct contact between the AQUAFINWM12 and the compacting machine should be avoided. <br />Application as waterproofing in accordance with <br />DIN 18533: <br />The fresh concrete composite film must be applied with <br />the fleece side to the formwork or substrate, before the <br />concreting. Overlaps must be welded; adhesive bonding <br />is not permissible!</p> <p>Application as waterproofing under floor slabs: <br />The fresh concrete composite film must be applied <br />with the transparent side to the substrate, before the <br />concreting. Apply AQUAFIN-WM12 to the appropriately <br />compacted, pressure-resistant, capillary-breaking layer <br />or blinding layer (concrete or thermal insulation) in <br />overlapping linear sheets. The overlapping width is 5 cm. <br />The joints are bonded by means of hot air welding or <br />adhered with AQUAFIN-CA. Avoid damage during the <br />subsequent work steps, e.g. laying reinforcement. Spacers <br />used shall have a large surface area at the support points. <br />The concreting of the floor slab must be professionally <br />applied and in accordance with the applicable standards <br />and regulations. It is particularly important to ensure <br />that the concreting is implemented free of voids or that <br />bonding is implemented covering the whole area of the <br />fleece layer. In doing so, direct contact between the <br />AQUAFIN-WM12 and the compacting machine should <br />be avoided.</p> <p>Hot air welding: <br />Device parameters: <br />• 220V hot air blower with stepless temperature <br />adjustment up to +600 °C and air flow regulator <br />• Heating power > 1400 Watt <br />• Width slotted nozzle 40 mm (perforated on the underside) <br />The welding of the AQUAFIN-WM12 is carried out <br />with handheld welding devices (e.g. Leister Triac) with <br />a temperature of +450 °C to +650 °C (approx. level <br />6.5). The sealing sheets are laid overlapping and tacked <br />at a max. pitch of 50 cm, parallel with one another. Then <br />the handheld welding device is guided slowly over the <br />joint at an angle of approx. 30°. In doing so, the sheets <br />are pressed together with a moderate force of > 5–6 kp <br />using a silicone roller, parallel with the sheet edge, until <br />a weld seam is created at the joint edges. Welding <br />is implemented over a width of approx. 4 cm. With <br />professionally prepared welding, a weld bead running <br />along the seam can be considered an indication of <br />a perfect joint. The joint seams are immediately leak-proof <br />and are fully cured after 24 hours. <br />Carry out trial welding before the hot air welding work. <br />In the case of applications on thermal insulation, suitable <br />underlays, which will be slowly pulled along with the <br />sheets during welding, should be used. The welding zones <br />are to be cleaned of any adhesion inhibiting substances. <br />In doing so, it is not permitted to use solvents or splice <br />wash.</p> <p>Application as waterproofing in formwork constructions: <br />The fresh concrete composite film must be applied with the <br />transparent side to the formwork, before the concreting. <br />AQUAFIN-WM12 is fitted to the top side of the formwork <br />construction in linear sheets, overlapping and fastened by <br />means of nail strips. The overlapping width is 5 cm. The <br />joints are bonded by means of hot air welding or adhered <br />with AQUAFIN-CA. Avoid damage during the subsequent <br />work steps, e.g. laying reinforcement or spacing struts. The <br />concreting must be professionally applied in accordance <br />with the applicable standards and regulations. It is <br />particularly important to ensure that the concreting is <br />implemented free of voids (gravel pockets) or that bonding <br />is implemented covering the whole area of the fleece</p> <p>2/3</p> <p>05/19</p> <p>Adhered with AQUAFIN-CA: <br />Generously apply AQUAFIN-CA to the overlap area <br />of the substrate and press the next sheet into the fresh <br />adhesive. The concreting process can take place no <br />sooner than 8 hours after adhesion. <br />Notes: <br />• The fresh concrete composite system should be stored <br />dry as a matter of principle. <br />• Do not store sharp objects or pallets on the fresh <br />concrete composite film. <br />• The current applicable regulations and datasheets are <br />to be observed! <br />Please observe valid EU safety data sheets!</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
