Due to weather and site <br />conditions, the given timings may be longer or shorter.</p> <p>Areas of application: <br />INDUCRET-BIS-5/40 is used as an anti-sag re-profiling <br />mortar for vertical, horizontal and overhead areas for <br />voids up to 40 mm. It is also suitable as a levelling <br />compound on swimming pools and tanks as well as for <br />forming pool edge details for subsequent waterproofing <br />or tile installation.</p> <p>Substrate preparation: <br />Cement-based areas must be sound with a good key <br />and be load-bearing, free from cement laitance, loose <br />components as well as adhesion inhibiting materials <br />such as release agents, dust, laitance layers etc. <br />Dependent on the project, prepare the substrate e.g. by <br />grit blasting, shot blasting, high pressure water jetting <br />(500–2000 bar), scabbling or planing. The prepared <br />substrate must have an open textured surface structure. <br />Adequately pre-wet the treated substrate 24 hours as <br />well as 2 hours before applying ASOCRET-BIS-5/40, <br />which at the time of mortar application must be matt</p> <p>Technical Data: <br />Colour: <br />cement grey <br />Basis: cement</p> <p>1/3</p> <p>39/18</p> <p>damp. Exposed reinforcing steel is to be treated <br />with the corrosion protection ASOCRET-KS/HB (see <br />requirements in the technical data sheet). <br />Minimum age of the concrete substrate: <br />28 days <br />Tensile adhesion strength of the concrete substrate: <br />min. 1.5 N/mm2</p> <p>mortar by wet spray techniques. <br />The substrate must be matt-damp when installing <br />ASOCRET-BIS-5/40. Re-profiling by wet spray is carried <br />out after the material has been mixed in a compulsory <br />mixer with a suitable feed pump and the use of a <br />MAWO nozzle. To ensure a regular spray pattern, the <br />use of a high performance site compressor is mandatory <br />(min. 4 m3 air/ 4–5 bar operating pressure).</p> <p>Product preparation: <br />Each 25 kg ASOCRET-BIS-5/40 requires a water <br />quantity of approx. 3.5–3.75 l water. <br />Initially add approx. 2.8–3.0 l water/25 kg <br />ASOCRET-BIS-5/40 and mix with the powder for <br />approx. 3 minutes. Then add the remaining quantity of <br />water and mix for a further 2 minutes to a homogenous <br />and lump free consistency. When mixing larger <br />amounts, we recommend the use of a compulsory <br />mixer. Only mix as much material as can be used within <br />60 minutes.</p> <p>Without compulsory mixer: <br />Pump system: High Comp Power <br />Pump unit: XP 120 <br />Water demand: approx. 190–200 litres/hour <br />Nozzle: MAWO nozzle 35/12 mm <br />Max hose length: 30 m <br />Control nozzle distance: 0.5–1.0 m</p> <p>Hand application: <br />ASOCRET-BIS-5/40 is applied together with the <br />mineral-based bonding agent ASOCRET-KS/HB. <br />ASOCRET-KS/HB is brushed into the prepared <br />matt-damp substrate using a hard broom to give <br />full coverage and fill surface pores. Apply the <br />ASOCRET-BIS-5/40 repair mortar to the required <br />thickness whilst the bonding agent is still wet. <br />Subsequently compact the mortar and strike off flush <br />with the surface. When applying to larger areas, the <br />thickness can only be applied up to 20 mm in one <br />layer. We recommend building up layers for thicker <br />applications. As an alternative, applications up to <br />40 mm in one layer can be achieved by spraying. <br />Wet spray application process: <br />When applying by wet spray techniques, the use of a <br />mineral-based bonding agent can be skipped. Apply <br />2 layers of ASOCRET-KS/HB corrosion protection at <br />least 72 hours before applying the ASOCRET-BIS-5/40</p> <p>PFT pump system: <br />Multi Mix compulsory mixer <br />Conveyor pump N2FU400/screw feed D8-1.5 <br />Reprofiling nozzle 35/12 mm <br />(Reprofiling spray tool) <br />Max hose length: 30 m <br />Control nozzle distance: 0.5–1.0 m <br />Inotec pump system: <br />Inomix compulsory mixer ZM80 Jet Mix <br />Inobeam F21 light/screw feed D8-1.5 <br />Mortar hose 25 mm diameter <br />Reprofiling nozzle 35/12 mm <br />(Reprofiling spray tool) <br />Max hose length: 30 m <br />Control nozzle distance: 0.5–1.0 m <br />Material application: <br />Through introduction of compressed air at the spray <br />nozzle, the material should exit the nozzle in a uniform <br />circular pattern. During the first spray coat application, <br />blow holes, honeycombs, voids behind the rebar, <br />irregularities in the wall, etc, should be filled and evened <br />out. The second spray coat should be used to build up</p> <p>2/3</p> <p>39/18</p> <p>desired material thickness, which can then be finished <br />with proper smoothing methods. <br />Post application treatment: <br />Once the ASOCRET-BIS-5/40 has been applied, <br />carefully protect the mortar surface from drying out <br />too quickly by using suitable measures. This may be <br />achieved by keeping damp for at least 3-5 days using <br />water mist spray or wet jute sheeting or covering <br />with other sheeting as necessary. The sheeting must <br />fixed to the area so that there is no air exchange <br />possible. Pay particular attention to post application <br />treatment when the mortar surface is exposed to <br />direct sunlight, draughts, large temperature variations <br />and/or low humidity. If the application of a mineralbased waterproof slurry is planned, then this can be <br />applied after approx. 24 hours as an alternative post <br />application treatment method.</p> <p>Important advice: <br />• Prior to commencing any concrete restoration <br />measures, the actual condition is generally to be <br />assessed by a specialist and/or Structural Engineer. <br />The test record is to be made available to the <br />applicator before starting the renovation work. <br />• Protect areas not to be treated from the effects of <br />ASOCRET-BIS-5/40. <br />• ASOCRET-BIS-5/40 mortar that has already started <br />to harden, may not be re-lifed through the addition of <br />water or fresh mortar as there is a risk of inadequate <br />strength development. <br />• Applications that are not clearly explained in this <br />technical data sheet may only be carried out <br />after consultation with and written confirmation <br />from the Technical Services Department of <br />SCHOMBURG GmbH. <br />• Observe pertinent regulations and guidelines. <br />Please observe a valid EU safety data sheet. <br />GISCODE: ZP 1</p> <p>This technical data sheet is a translation from German and does not consider local building codes or legal requirements.
