It is furthermore <br />suitable as a levelling compound for swimming pool <br />tanks and other tanks as well as for forming pool <br />edge details for the subsequent application of bonded <br />waterproof membranes or the installation of tiles. <br />Technical Data: <br />Basis: <br />factory blended dry mortar <br />Colour: cement grey <br />Grain size: <br />< 1.0 mm <br />Bulk density: <br />approx. 2.0 kg/dm3 <br />Pot life*: <br />approx. 60 minutes <br />Overcoat after: <br />min. 1 day</p> <p>Substrate/ <br />application temp: <br />min. +5 °C, max. +30 °C <br />Compressive strength: 24 hrs, approx. 11 N/mm² <br /> <br />7 days, approx. 30 N/mm² <br /> <br />28 days, approx. 40 N/mm² <br />Flexural strength: <br />24 hrs, approx. 2 N/mm² <br /> <br />7 days, approx. 7 N/mm² <br /> <br />28 days, approx. 8 N/mm² <br />Consumption: approx. 1.6 kg/m²/mm <br />thickness <br />Cleaning: <br />Thoroughly clean work tools <br /> <br />with water after use <br />Packaging: <br />25 kg bag <br />Storage: cool and dry, 12 months in the <br />original unopened packaging. <br />Use opened packaging <br />promptly. <br />*) At +23°C and 50% RH. Due to weather and site conditions, these <br />given figures may lengthen or shorten.</p> <p>Substrate preparation: <br />The substrate must be load-bearing, sound, have a good <br />key and be free from adhesion inhibiting materials such <br />as release agents, dust, laitance layers etc. Substrate <br />preparation e.g. grit-blasting, shot-blasting or high pressure <br />water jetting (500–2,000 bar) is required if no previous <br />concrete repair works have been carried out. <br />Adequately pre-wet the prepared substrate before <br />applying ASOCRET- BIS-1/6 at a time when the substrate <br />is matt-damp. <br />Minimum age of concrete substrate: 28 days <br />Tensile adhesion strength of the <br />concrete substrate: <br />min. 1.5 N/mm2 <br />Product preparation: <br />Dependent on the desired consistency, place approx. <br />5.0–5.25 l of clean water into a clean mixing bucket and <br />whilst mechanically stirring (drill approx. 300–700 rpm), <br />mix in as much dry powder until a lump free, smooth paste</p> <p>1/3</p> <p>48/20</p> <p>is achieved. The mixing time is approx. 2–3 minutes. <br />Allow to mature for 5 minutes then mix through once <br />again. When mixing larger quantities, use a forced <br />action mixer. Only mix as much material as can be used <br />within the pot life given above. <br />Application by hand: <br />Apply a scratch coat of ASOCRET-BIS-1/6 to the <br />prepared substrate and then lay to the desired thickness. <br />Striking off the mortar is determined by the application <br />involved using a suitable tool (lath, trowel etc) within the <br />pot life. After leaving for the appropriate length of time, <br />the surface can be finished using a felt-board or spongeboard. <br />Wet spray application: <br />The surface to be treated must be adequately wetted <br />until matt-damp. <br />Re-profiling with wet spray techniques is carried out <br />after mixing in a compulsory mixer with a suitable feed <br />pump using a 12 mm spray re-profiling gun or a <br />35/12 mm MAWO nozzle. For an even spray <br />pattern a high output construction compressor (min. <br />4 m3 air / 4–5 bar operating pressure) is a mandatory <br />requirement. <br />Without compulsory mixer: <br />Pump system: High Comp Power <br />Pump unit: <br />XP 120 <br />Water demand: approx. 160–180 l/hr <br />Nozzle: <br />MAWO nozzle 35/12 mm or 12 mm <br /> <br />re-profiling spray gun <br />Max. Pipe length: 30 m <br />Control nozzle displacement: 0.5 –1.0 m <br />PFT pump system: <br />Multi Mix compulsory mixer <br />Feed pump N2FU4000 / screw conveyor D8-1.5 <br />Reprofiling spray gun 12 mm <br />Max. Pipe length: 30 m <br />Control nozzle displacement: 0.5 –1.0 m</p> <p>Inotec pump system: <br />Inomix compulsory mixer ZM80 Jet Mix <br />Inobeam F21 light / screw conveyor D8-1.5 <br />Reprofiling spray gun 12 mm <br />Max. Pipe length: 30 m <br />Control nozzle displacement: 0.5–1.0 m <br />Material application: <br />Through the addition of air at the spray nozzle, the <br />mortar is sprayed in a circular manner in order to <br />achieve a clean spray pattern. The first pass of the <br />spray head is to fill holes and cavities and to even out <br />irregularities in the substrate. The second spray pass is <br />to achieve the required thickness and to finish with a <br />suitable smoothing tool. <br />Post-treatment: <br />Following the application of ASOCRET-BIS-1/6, it is <br />fundamentally necessary to protect the mortar surfaces <br />from drying out too quickly using suitable measures <br />Keep damp for at least 3–5 days using mist spray <br />nozzles or wet jute sacking as required also covered <br />with polythene sheets. The polythene sheets must be <br />fastened to the area treated, so that air exchange is <br />excluded. If the area in question is exposed to direct <br />sunlight, draughts, large temperature fluctuations and/or <br />low humidity then after care treatment must be intensified. <br />If it is intended to apply a mineral-based waterproof <br />slurry, then this can be used as an alternative after care <br />treatment after approx. 24 hours. <br />Important advice: <br />• Prior to carrying out concrete repair works the <br />actual condition should be inspected by an expert <br />or Structural Engineer. The inspection report is to be <br />given to the applicator prior to commencement of <br />repair work. <br />• Protect surfaces not being treated with <br />ASOCRET-BIS-1/6.</p> <p>2/3</p> <p>48/20</p> <p>• ASOCRET-BIS-1/6 mortar, which has already <br />stiffened should not be re-lifed by adding more water <br />or fresh mortar as there is a risk of inadequate strength <br />development. <br />Please adhere to the valid EC Safety Data Sheet. <br />GISCODE: ZP1</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.
