Used as <br />a levelling mortar in swimming pools and on pool <br />surrounds, as well as for shaping pool edge details <br />for subsequent application of bonded waterproof <br />membranes or the installation of tiles. <br />Technical Data: <br />Colour: cement grey <br />Basis: cement <br />Grain size: <br />up to 2 mm <br />Bulk density: <br />1.6 kg/dm3 <br />Green density: <br />2.1 kg/dm3 <br />Working life: <br />approx. 60 mins at +20 °C <br />Overcoat after: <br />min. 1 day <br />Application temp.: <br />+5 °C to +30 °C <br />Compressive strength: 24 hrs approx. 14 N/mm² <br /> <br />7 days approx. 50 N/mm² <br /> <br />28 days approx. 60 N/mm² <br />Flexural strength: <br />24 hrs approx. 4 N/mm² <br /> <br />7 days approx. 8 N/mm² <br /> <br />28 days approx. 9 N/mm²</p> <p>Art.-No. 2 05557</p> <p>Covering with bonded <br />waterproof membranes/ <br />tiles: <br />approx. 24 hrs <br />Cleaning: <br />thoroughly clean tools after <br /> use with water <br />Packaging: <br />25 kg bag <br />Storage: <br />12 months when stored <br /> <br />dry in the original unopened <br /> <br />packaging. Use opened <br /> packaging promptly. <br />Substrate preparation: <br />Before applying ASOCRET-FM40, exposed reinforcing <br />steel must be treated with the corrosion inhibitor <br />ASOCRET-KS/HB according to the Technical Data <br />Sheet. Cement-based areas must be solid, finely textured <br />and load-bearing, free from cement laitance, loose parts <br />as well as adhesion inhibiting substances (oil, grease, <br />rubber marks, paint residues or other contamination). <br />Preparation of the substrate is necessary such as e.g. <br />grit blasting, shot blasting, high pressure jet washing <br />(500–2000 bar), scabbling or planing. The prepared <br />surface must have an open-pored structure. Adequately <br />pre-wet the treated substrate 24 and then 2 hours <br />before application of ASOCRET-FM40. At the time of <br />mortar application, the surface must be matt-damp. <br />Minimum concrete substrate age: 28 days <br />Mean surface tensile adhesion strength: <br />min. 1.5 N/mm² <br />Product preparation: <br />Production of the repair mortar: <br />• ASOCRET-FM40 <br />25.0 kg <br />• Water <br />approx. 3.5 – 3.75 litres <br />Material consumption (final mix): <br />Approx. 1.8 kg/m²/mm thickness <br />Approx. 1.0 l/mix = 2.13 kg <br />Fill up to 80% of the above water quantity into a clean <br />mixing bucket. Continuously add the above quantity <br />of ASOCRET-FM40 whilst continuously stirring with a <br />suitable drill mixer (approx. 300 rpm). Thoroughly mix <br />the material for 3 minutes to a lump free mortar. Then</p> <p>1/3</p> <p>49/14</p> <p>add the remaining water and mix for a further <br />2 minutes. Allow to stand for 2 minutes then re-mix <br />briefly. When large quantities are prepared, use a <br />compulsory mixer. Only mix as much material as can <br />be used within the times given above. <br />Application tools: <br />Hand mixing trowel, wooden board, steel trowel, hand <br />held lath, rubbing board <br />Application by hand: <br />ASOCRET-FM40 may only be used in combination with <br />the bonding coat ASOCRET-KS/HB. <br />The maximum exposed area applied must not exceed <br />1.0 m². <br />Bonding coat: <br />Cover the prepared matt-damp substrate with <br />ASOCRET-KS/HB by working deep into the pores <br />with a hard broom. <br />Subsequent application of the repair mortar <br />ASOCRET-FM40 is to be carried out into the wet <br />bonding coat. <br />Apply and spread ASOCRET-FM40 onto the wet <br />bonding coat to the required thickness using a suitable <br />tool. Subsequently compact and smoothen the mortar. <br />Application by wet-spraying method: <br />When applying using wet spraying methods, the use of <br />a mineral-based bonding coat can be omitted. Apply <br />2 layers of the corrosion inhibitor ASOCRET-KS/HB a <br />minimum of 72 hours before installing ASOCRET-FM40 <br />by wet spray methods. The prepared surface must have <br />an open-pored structure. Adequately pre-wet the treated <br />substrate 24 and then 2 hours before application of <br />ASOCRET-FM40. At the time of mortar application, the <br />surface must be matt-damp. Re-profiling by wet spray <br />methods follows mixing the material in a compulsory <br />mixer with a suitable feed pump and using a MAWU <br />nozzle. To achieve an even spray pattern a high <br />performance construction compressor (min. 4 m3 air/ <br />4 – 5 bar service pressure) is essential.</p> <p>Without compulsory mixer: <br />Pump system: High Comp Power <br />Pump unit: XP 120 <br />Water demand: approx. 190 – 200 l/hr <br />Nozzle: MAWO nozzle 35/12 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 as well as to fill <br />out voids behind the reinforcing steel 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-FM40, 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 <br />cannot take place. If the area in question is exposed to</p> <p>2/3</p> <p>49/14</p> <p>direct sunlight, draughts, large temperature fluctuations <br />and/or low humidity then after care treatment must be <br />intensified. If it is intended to apply a mineral-based <br />waterproof slurry, then this can be used as an alternative <br />after care treatment after approx. 24 hours. <br />Health & Safety: <br />ASOCRET-FM40 contains cement that forms an <br />alkaline reaction with moisture. Therefore contact with <br />the eyes and skin is to be avoided and mortar splashes <br />are to be thoroughly washed off immediately with <br />plenty of water. On contact with the eyes, seek <br />medical attention from an eye specialist. Please store <br />ASOCRET-FM40 out of the reach of children. <br />Important advice: <br />• P rior 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 />• P rotect surfaces not being treated with <br />ASOCRET-FM40. <br />• Cover with suitable sheeting to protect from rain. <br />• Marginal temperature: +5 °C to +30 °C. <br />•W <br /> hen preparing ASOCRET-FM40 only use mains or <br />drinking water. Material that has started to stiffen may <br />not be diluted with water or more powder added. <br />There is a risk of an inadequate bond. <br />• Application</p> <p>to larger areas can be carried out up to <br />max. 20 mm by hand with a trowel in one layer. For <br />greater thicknesses, we recommend building up in <br />multiple layers. If sprayed, thicknesses up to 40 mm <br />are possible in one layer. <br />•A <br /> pplications that are not clearly explained in <br />this technical data sheet may only be carried <br />out after consultation with and written confirmation <br />from the Technical Services Department of <br />SCHOMBURG GmbH & Co.
